We had Eugene come out to inspect our flat roof after purchasing our home a week ago. He was very knowledgeable and provided us with honest feedback of the condition of our roof which, at this time did not need any repairs. I really appreciate the integrity and honesty, and would love to do future business.

I found Diamond through Reddit, and I’m glad I did. The owner, Eugene, is incredibly friendly and efficient—he got me quoted and scheduled for a roof repair quickly. My roof is a flat deck on top of a townhouse, which can be tricky, and it’s hard to find contractors experienced with this kind of work. Eugene and his crew did a fantastic job. They kept me updated with frequent progress photos and clear communication, so I never felt out of the loop. I also appreciated that Eugene personally visited the site often—it really shows how much he cares. Highly recommend!

Diamond Roofing replaced an entire roof for an apartment complex within 3 days. Fast, efficient and a job well done!

Eugene and his crew did a fantastic repair job on our condo roof. Reasonably priced and very professional. I highly recommend Diamond Roofing.

I highly recommend Diamond Roofing. They have now done two new roofs for me with excellent results. I won't use anyone else in the future. Their work is exceptional. My neighbors all admire the work they did. I was home during the process and I got to see the work they did. The crew was amazing each with expertise. Thanks Diamond.-Brian Russell

Eugene's crew were great. They were professional, incomparably hardworking and very considerate of my property with daily clean up. My roof looks fabulous. I would give them 10 stars if I could.

Eugene with Diamond Roofing completed a large multifamily apartment roofing project for our company and did an incredible job. His pricing was competitive, they began and completed the job on time, and the workmanship is excellent.
Eugene was recommended to me by a general contractor that I trust, and he told me that Diamond Roofing is the best roofing company in Seattle by far. Nothing I experienced makes me doubt his expert opinion. He’s getting started on another large multifamily project for me soon.
Highly recommended.

I could not be happier with Eugene and his team. I am a real estate agent with a client that needed a new roof. He came highly recommended to me by another agent in my office and she was absolutely right. His professionalism, responsiveness and quality of work was better than expected. I will be referring him to other clients in the future, and hire him when it comes time to do my own roof.

Eugene and his team provided a very competitive bid compared with other reputable roofers, and performed my client's roof replacement in the timeframe promised and price as stated. As a Realtor I really appreciate professionals like Eugene who provide a clear bid, commicate well, do quality work, and leave the job site as spotless as they did, even though nobody else was on site the days they did the work. I've already recommnded Diamond to other clients and friends !

Eugene and crew did an excellent job to install a new roof on our house. They offered one of the best prices when we shopped around and stuck to the original quote in the end. Based on my experience dealing with them, I would definitely hire them again for our next roof project.
Throughout, his crew worked very diligently. They came shortly after 8am everyday and worked until 7-8pm. While we would have liked to sleep in on those days (haha...), we appreciated that they kept the project on track without our involvement. Eugene also set the expectation upfront. In addition, he sent us updates during the day so we could see how the project progressed.
One thing that we really liked was that they cleaned up well at the end of each day. This was especially important since we had to live in the house while it was being worked on. We didn't want a construction zone.
Overall we were very happy about how well the project turned out. Our new roof looks pretty fantastic.

Eugene and his team did a fantastic job installing a NuRay standing seam metal roof! He was always available to answer questions and happy to address my ideas about installation. The job was completed on time so our solar system from Sunergy could be installed. Our neighbors stop by to comment on the beautiful roof we have now. Many thanks!

Eugene and his team did a great job on replacing our roof shingles. They started on a Tuesday and were finished by early afternoon on Thursday. Eugene was great at communicating with me. He sent photos every day with progress. This team is extremely hardworking. They made sure to tidy up at the end of each day. We are very happy with our new roof. I would highly recommend Diamond Roofing to anyone!

Eugene and his crew worked very well on this project. During the wind storm, a tree fell through our bathroom remodel project. Damaging 5 trusses. The old roofing was outdated and needed an upgrade. We needed a whole roof replacement and sheathing installation. We work together as unit, to demo the damaged roof, to rebuild the trusses and his crew reshingled everything! Everyone was professional, kind and hard working! The project was expected to take 7 days but was finished in 4 days. Pretty impressive! Highly recommending this company and reusing Eugene in Future projects!
Thank you!

We had a great experience with Eugene and his team replacing our flat roof. The entire process was seamless and our new roof looks great!

Diamond Roofing just got done replacing our roof. The previous roof was a hack job. Eugene reviewed the work that was done, made suggestions on what can be done with minimal cost and what would be the right fix. Their quote was reasonable. The work was scheduled within days. The crew showed up as scheduled and finished the work with quality and on time. When they were done, the site was cleaned up and left as if no one had been there, except for the brand new roof. Eugene kept in contact through out the roof replacement with photos (I was traveling). Super courteous and responsive. I highly recommend Diamond Roofing.

I couldn't be happier with the team at Diamond Roofing and Construction. They show up, do what they promise, an provide quality workmanship.
My roof was done in a long day, and a little bit of work on flashing the next morning.
Gene is honest, and fair with the pricing.
I did shop around and got the best product and pricing from Diamond. If you need a roof, give Gene a call. We're very pleased with our new roof. Thanks Diamond Roofing and Construction Team!

Eugene and his team recently completed our condo's roof replacement and did an excellent job! Eugene came to do our estimate, and gave us a competitive proposal very quickly amongst several other roofing companies. He was very responsive and helpful throughout the process, keeping us updated with progress updates, photos, and answering our questions throughout the replacement process. His team worked tirelessly and finished our roof replacement ahead of schedule! I would not hesitate to recommend Diamond Roofing to anyone I know!

I’m a local property manager and I have been using Diamond Roofing for several years to do repairs and re-roofs. I recently needed their services to replace a composition roof and a detached garage torch down roof on a personal property of mine. I got 3 bids (just as I would for work) and they had the best pricing. Eugene was great about following up with me (we weren’t ready right away) and everything went according to his plan. Their crew was on time, very respectful, clean, and the schedule was exactly what I was told. I do plan to continue to use them for future projects. Thank you Eugene and Rene for being so professional

Eugene and his crew did a great job replacing the roof of my townhome. They communicated very well and replaced the wood when they saw it was needed. They finished the work in 3 days and provided updates throughout the entire process. I would recommend them.

Diamond Roofing recently completed the installation of our new Roof and I would recommend them to everyone without hesitation. I've dealt with many contractors/companies over the years on our house. These guys stand out. Eugene, the owner, takes great pride in his company and the work they do, and it shows. Eugene was great to work with, upfront with all costs and always with timely communications on the project's progress. His extensive hands-on knowledge of roofing was comforting to see and he told us about our roof in fully understandable detail. His crew was very courteous and as unobtrusive as a roofing crew could be. They cleaned up at the end of every day's work. All was much appreciated by my wife and I. Our roof is not easy, high with a number of different angles. Their craftmanship in handling that was obvious in the details of the work. Really nice touches. All with no hidden costs and fine pricing.

For any roofing project I will highly recommend Diamond Roofing. Very professional and what was the ultimate reason I choose them is their communication skills. Always responding, always answering any questions I had. They were sending me photos of the every step of the roof replacement starting with demolishing to the final finished roof. I have a great collection of photographs of the project.
Overall very professional and very reasonable priced.
All thumbs up!

Would highly recommend Diamond Roofing! Very professional. Crew was great, and cleaned each day before leaving my house. I really appreciated all the quality work you did!

Diamond Roofing did an amazing job on our Bellevue home: fast, economical, respectful to our privacy and polite with our neighbors. After 20+ years of PNW weather we couldn't list our home without this essential service.

From a property management prospective, this company is incredible! Their communication, turnaround time, pricing, and overall quality of work is amazing. Eugene and his team are great to work with :)

Eugene and his team did an awesome job replacing our roof. I would highly recommend Diamond roofing for anyone who wants the job to be done with a great price, reliable work and clear communication. I found Diamond roofing through google review and I hope my review here could save others some time finding the right contractor/company for their roofing project. Here is my story:
Shortly after contacting for a free quote, Eugene showed up and went through our project. Unlike other company’s salesman, he inspected around the house, and explained the process with professional opinions including potential saving points. Once the quote is out, he answered all my follow up questions, and revised the contract for multiple upgrades upon my request. All the communications are in-time and clear, the quote price is pretty good compare to other competitors, and I decided to sign the contract with Diamond roofing.
The work started on a Tuesday morning and completed by Saturday. Throughout the week, Rene and his team members always started work early in the morning. Unfortunately I have to stay at home during the project and hear the noises. But this also gets me the first-hand experience to share that I DID see the crew worked so hard and paid attention to the details; Rene was on site all the day and supervised team member’s work from time to time, and Eugene followed up with me for questions and shared tons of photos everyday.
A specific thing to call out is about our skylight. The original skylight is not the standard size and model. Eugene and Rene figured out a solution quickly and explained to us for approval. The solution requires additional wood frame to support the skylight. Rene painted the wood frame to match our dry wall. Check my photos, it is beautiful and looks like an original design. In the end, our skylight got upgraded to these fancy ones with remote controller, and my kid got very excited about it.
Once the project was completed, Eugene took a final check of the roof and reminded me multiple times that once the trash bin is removed from our driveway, I shall sweep the driveway again in case any nail was left.
I do not have the expertise to judge if the quality of their work is really good or not, only the time will tell. But for what I experienced so far, the team is professional with their on time work, rationale to pay attention to details, in time response, and clear communication. Our new roof looks beautiful and I would recommend Diamond roofing for others to get their premium service.

I work with Diamond Roofing over the years. I’ve never been disappointed. They really know what they are doing-anything roof. This is including specialty type of roof like mine (flat roof). Eugene the owner is very professional and he does train his crew very well. They start the job on time, well done, and cleans after well. If I could give them 6 stars, I would!

I contacted Eugene and Diamond Roofing to come out to take a look at a leaking, flat garage roof that had caused some interior damage. I had gotten a quote earlier in the same day from a different company, who told me that they weren't able to locate the exact source of the leak and recommended replacing the whole roof, which would cost ~$9,000.
Eugene was up on the roof for about 5 minutes, identified the problem as a completely clogged drain pipe (I'm a bit embarrassed), snapped some photos to show me, cleaned it out, and explained how it had caused water to get inside the garage.
He saved me from an unnecessary and wasteful $9k replacement roof, additional debt, and a lot of stress. That kind of honesty can be really hard to find, and is a stark contrast to the other bid I got that same morning.
I can't say enough good things, thank you!

Great company! Highly recommend! Very efficient, professional and clean! These guys work hard and do an excellent job! Such a relief to have a new roof in such a short time! Thank you guys for your work!

We had an amazing experience with Eugene and Diamond roofing! They were professional, punctual, and did an outstanding job on our roof! The work was completed earlier than promised and everything was cleaned up perfectly afterwards. They were careful while working and took extra care around the garden area.
Highly recommend them to anyone looking for quality roofing work!

The best roofers I have ever seen on site, fast, super clean, top notch quality, they replaced our roof in 2 days, with a bunch of repairs, Thank you Eugene, I will highly recommend to anyone who needs a new roof, but is afraid of the mess.

Eugene and his team did a great & thorough job on our roof repair. Eugene was easy to communicate with, on-time and straight-forward. The team was tidy and efficient. Also, they were competitively priced (lower than a second estimate we received from a different company).

Eugene and his guys were amazing! They did our entire roofing project in two days. At the end of each day, the crew picked up and left a clean job site. The porta potty and dumpster were picked up right away once the project was completed. I would definitely recommend them.

Eugene and his crew were so professional in all phases and details of replacing my roof. They went far beyond what my expectations were. This company is honest and communicated with me through the whole process. Excellent in every way, finishing the job as promised. Five stars isn’t enough many more stars are needed. I’m very happy. Thank you to Eugene , GS

Eugene
and his crew did an amazing job
On our roof and cyclone bombed roof and siding from the November storm they were the best price we got several estimates they got the job done fast and efficient I would give them 5 stars all the way highly recommend them

Eugene and his crew went above and beyond our expectations the crew was very professional our house was badly damaged by the cyclone bombing in November the roof and siding were severely damaged the new roof looks perfect we are so pleased and Thankful for the work they did very fair prices and got the job done on time 5 stars all the way

Diamond Roofing and Construction recently completed a roof replacement on our home in West Seattle. The owner, Eugene K, did a great job explaining the options and promptly provided a very reasonably priced estimate. Eugene's crew began the work several days later and did an excellent job, finishing the project in 2.5 days. Eugene and his foreman checked in with us each day to update us on their progress. We are 100% satisfied with every aspect of the project!

Bid and followed through on a 1/2 day repair job. Excellent communication, easy to work with, good crew and job well done! Rare these days to find a company that will do this type of small job
work well. Thank you.

Working with Eugene and his crew was great. Anytime you called Eugene with a question, he either answered right then and there or he got back to you within just a few minutes.
They did a great job on the roof and they picked up after themselves. The price they charged was extremely reasonable.

Diamond Roofing has been a shining example of hard work, integrity, and quality customer service. When we needed roof and chimney repairs for our building, Eugene and his crew provided us with a fair quote, and high quality results.
As a condo HOA, we need to be mindful in our hiring, and we don't hesitate to give Diamond Roofing the highest marks.
Thanks guys!

Eugene and his crew were top notch professionals from start to finish. They really went the extra mile for us. I highly recommend giving Diamond Roofing a call for all your roofing needs.

We had a leak in a flat section of our roof. Eugene responded quickly and dispatched a crew without delay. They were friendly, seem to have done good work, and left the site totally clean.
10/10. No notes.

Not five stars.
10 stars.
Eugene (the owner) and his team (Rene & Crew).
Did the work in Feb 2025.
The weather was perfect but cold in the first two days.
After that it was rain, cold, snow, and freeze.
Somehow, someway, they got it done in less than a week.
I was concerned with the weather conditions all around.
But the work got done on time.
Eugene kept me calm by responding to all my questions and concerns.
The crew was unbelievable.
Their work ethic and professionalism are second to none.
The roofing product was first class.
The workmanship was of highest quality.
Almost impossible to put these into words.
As an owner of the house and getting the roof replaced will only happen once in my lifetime.
This was so important to get it done right.
I got a lot of bids.
The price was too good to be true.
Now that the work was completed.
I would pay the higher end of my bids knowing the excellent work they did.
Throughout, Eugene was communicating with me timely.
How can anyone top this?
It would be very difficult.
But not with Diamond Roofing.

Eugene and his guys did an amazing job repairing my damaged roof from the crazy storm. Very
professional and on time and great company to work with.
I could not be happier with the quality, service, and attention to detail. The repaired section completely blends into the rest of the roof.

I had a great experience with Eugene and his crew at Diamond roofing. They were very responsive after I found my flat tar-down roof leaking and began work a few days later, working through snow. They finished a day ahead of schedule and were competitively priced. Eugene and his crew were very professional and personable. They replaced some damaged plywood and insulation. They even added additional venting for free. I highly recommend them.

I had my entire roof replaced a week ago that also included replacing all existing plywoods and repairing several damaged rafter tails, and I had a tight dead line to have it all done. Eugene and crew did a great job. The new roof was done professionally and ahead of schedule. I would not hesitate to recommend to anyone who is looking for a skilled and trustworthy roofing contractor.

I normally don't write reviews but was so pleased with Diamond's responsiveness and professionalism I felt compelled to. Eugene was quick to put an estimate together which was very competitive and they were able to fit in a fairly sizeable flat roof repair job on short notice. There was a lot of extra rot damage that was not initially discoverable and the cost for the extra work required was very reasonable. The job site was left spotless. I would definitely use them again.

Eugene came out to do a free estimate and his bid was competitive with two other companies we were working with. Ultimately decided on diamond roofing because of the communication, attention to detail, and honest feedback. Team came out during a busy holiday week to complete the repair. Easiest fix I’ve ever done as a new home owner! Was of excellent quality and would highly recommend Eugene and his team!

Eugene with Diamond roofing did a great job on our apartment building roof. We found him through The Apartment House Association. He came out to give us a bid which was competitive with others we had received. He got us on the schedule quickly after finalizing our contract. He and his crew worked around the fall rainy weather and communicated every step of the way through text, email and lots of photos. Eugene went above and beyond to make sure that everything went smoothly. Thank you so much for everything! We appreciate it!

A+++ So thankful for the work Diamond Roofing did for us! We had a leaking skylight replaced and a tree branch that had penetrated our roof, we didn't even know about. The team was great and the work was timely, fairly priced and very professionally done. We went with Diamond Roofing off a recommendation from Next Level Chimneys. They were spot on. Use this business and you will be very happy!

If your looking for a honest price and a contractor who is willing to stand behind his work, look no further. We have worked together on numerous projects and will continue to trust him with our clients and our business. From residential to commercial, new builds, windstorm tree damage to remodels and new penetrations Eugene at Diamond has come through for us on each project. We recommend him to anyone who asks for roof work. No questions asked. We have been at this a while and he's one of the good ones, were more than happy we have him on our team.

Diamond Roofing is seriously a game-changer! From start to finish, their communication was on point—no guessing, no stress, just smooth sailing. And Eugene? What a rockstar! He’s got an incredible eye for detail and was so easy to work with—it felt like teaming up with a friend who just happens to be a roofing pro. The work they did was top-notch and lightning fast. If you want a roofing experience that’s actually enjoyable, Diamond Roofing is the way to go. Highly highly recommend them!

Had a leak in my roof over the holidays and they were out to fix it quickly. Reasonable price friendly crew easy to work with

Had a fantastic experience with Eugene, Rene, and the whole crew! These guys installed a new roof for me in less than a week and did a phenomenal job. They were extremely proactive in communications and meticulous in their work. Really happy with the entire job.

I would Highly Recommend Diamond Roofing to anyone wanting an honest bid, hard workers and good communication.
Diamond Roofing is an awesome company to work with. I called and asked for a quote due to the reviews I read about the company. Eugene responded within a day and I got the quote within a couple of days. The estimate was right in the ballpark of others and lower then some.
My roof was old and I lost many shingles due to the bomb cyclone in November. I had hoped they could start soon. Sure enough Eugene was able to put me on the schedule for the following week.
Eugene and his crew were great. They kept me informed of all that was happening and Eugene would send me photos all along the process. The job was started on a Tuesday and they finished by Saturday morning. They worked hard and the site was cleaned up at the end of the day. I was very impressed by their work ethic.

Diamond roofing and construction are fantastic. Had an issue with my parents after the last big windstorm and owner sent a man out day after and repaired a defect from the storm asap and did it as a courtesy. Very efficient and courteous. Prior to the storm Diamond Roofing put a new roof on my parents house and price and service were great. Highly recommend and thankful we still have great people like that out there . Trustworthy people, it is like having a good buddy in the business

As a Property Manager, I love having trusted vendors available to assist. Diamond Roofing has been nothing but great to work with and I will be using them in the future. Thank You!

We just had Diamond Roofing do 2 urgent roof replacements on our rentals. They are very good, fast and did a great job of cleaning up any mess. Would highly recommend.

Eugene and his team was a pleasure to work with. Efficient communication and high quality work. They were able to find all the leaking issues on my roof and patch them before the continuous raining days. Thanks for the help! Definitely recommend!

I got 7 quotes over two weeks and decided to go with Diamond Roofing. My project had quotes ranging from $16,000 to $32,000, which really shows the huge spectrum of prices that will get thrown at you, and the range in quality. Their offer was best priced for the quality - provided the best shingle (Malarkey Legacy), and said that they can do any shingle I wanted, giving me quotes for other shingles such as the Northgate Certainteed upon my request, with no bias on their side. I added on new 6K gutters and downspouts, they removed an unused and ugly chimney at no extra cost to me, and kept me informed every step of the way. No hick-ups, top quality, and 15 year warranty.

I recently had roofing work done by Abel and Max, small torch down roofing. Eugene the estimator arrived on time to the appointment, later same day I received and estimate. We had a reviewed to the estimate, detailed and transparent estimate, and we got scheduled a week after.
Abel and Max were hard at work, remarkable efficiency ensuring that the work was carried out meticulously and on schedule. Two days work, maintaining a clean and organized work site.
The quality is the torch down roofing work was exceptional. The attention to details and craftsmanship was evident from Abel and Max.
Seamless communication with pictures during the installation. Highly recommended if you have a project like this.

Eugene was helpful with coordinating a small roof leak repair for our old home. The team is professional and responsive. I highly recommend Diamond Roofing + Construction!

I'm very happy with our roof replacement from Diamond Roofing. They did quality work, communicated every day with progress, and they were proactive with suggestions to make sure every piece of my project was exactly what I wanted.

Eugene did a great job of communicating the status of the job with me. His team had a “can do” attitude and finished a difficult job at the price he committed to. His team is honest and did more work than I anticipated. Great work Eugene and team.

Eugene and his crew did a great job on our Church roof repair and decided to call him back to install a new cap on our exhaust stack that got blown off during the wind storm. I highly recommend them.

I had the pleasure of working with Eugene and the guys at Diamond Roofing. Eugene was on top of everything. Very professional and responsive. The guys worked quick and efficiently. Strongly recommend them for anyone looking to get their roofing replaced.

Eugen, you’ve done it again! Five-star work doesn’t just happen, and I’m so glad I hired you for my main house again. The job was fantastic, and you went above and beyond by coming out to replace a flipper vent to match the color of the others after it was mistakenly painted with gloss paint. That’s the level of attention to detail you provide. I’m really grateful for the hard work you all put in, especially during the cold winter months. Rene and his crew did an amazing job with the meticulous work. Your dedication really shows, and I’m so excited to enjoy my new roof and gutters. Thank you for everything!

Our HOA had a fantastic experience with Diamond Roofing! Diamond replaced multiple roofs in our community this past summer and the entire process was positive and seamless. Their pricing was highly competitive and fair and Eugene’s exceptional communication and responsiveness really set Diamond apart. I really enjoyed working with Eugene and his team on this project and would readily work with them again.
In addition to replacing multiple roofs, Diamond also replaced all of our gutter systems, vent caps, skylights, skyhooks, multiple fascia boards, and multiple soffits.
While here, Diamond discovered several builder errors that Diamond then remedied. The original builder had failed to install any flashing on the roofs or fascia; had improperly vented multiple ducts on one building; and had failed to install the proper venting structures throughout two of the buildings’ roofs (which caused mold). Diamond corrected all of these issues. For the latter, they collaborated with our mold remediation company to install the proper venting structure design to create proper airflow.
Eugene was on site almost daily to check in with his team and with me to make sure everything was going well. He was generous with his time and was happy to walk me through the elements of the work when I had questions. He sent me photo updates regularly of the work progress, which was awesome because I could then send those photos to update everyone. This was also great for transparency. We didn’t have to wonder what quality of work was being done, because we could see it.
Diamond’s bid was accurate and the project completed within budget and on time! Diamond was early or on time each day, and cleaned up at the close of each afternoon. Eugene maintained excellent, proactive communication throughout the project and was a fantastic person to work with. Our roofs and gutters look amazing! I highly and enthusiastically recommend Eugene and Diamond Roofing!

The other reviews are spot on. These guys re-roofed my house and did an awesome job, on schedule, and at very competitive price. And unlike some of the other companies that quoted us, they chose the best materials and approach for each aspect of the job. Communications from the owner were great from the start to the finish of the job, and we received photos daily of progress from the roof. Once the job was done, they left the property exactly as they found it. Overall, highly recommended.

Eugene and his team displayed great workmanship and care for their clients. From start to finish, he was very communicative and ensured that all of my concerns were thoroughly addressed. He made sure to include me throughout every step of the roof replacement process, providing full transparency while being educational. In comparison to many other roofers during the screening process, Diamond Roofing checked every requirement and proved to be a great choice by the end, not leaving any stone unturned until I was 100% satisfied.

I had my roof replaced with Diamond Roofing. I worked with Eugene to get a roof estimate first since I wasn't sure if it was the right time for replacement. He gave me a very honest feedback and 2 quotes, one for replacement and one for repair. I got quotes from other roofing companies too and they all pushed for replacement but Eugene wasn't pushy like that at all and actually advocated for repair.
My wife and I decided for replacement. It simply was because we had 2 leaks before caused by unprofessional roof cleaning using pressure washer(!!!) and didn't trust the roof anymore. From prior inspections we also knew that the roof was also installed poorly. Eugene and his team however did a fantastic job installing the new roof. No shortcuts and high quality materials. He kept me up to date by sending me pictures in the different stages. The crew did cleanup of the site every day. Overall a great experience and very competitive pricing but of course what I value the most is the honesty and excellent workmanship. I must recommend Diamond Roofing to anyone who cares to listen :)

As a Project Manager I am always looking to work with professionals that will get the job done no matter what is thrown at them. Diamond Roofing has done great work on multiple projects for CDK Construction. Look forward to working with them again in the future.

Gene was nothing short of professional. He and his crew were on time, honest, upfront, and friendly. They explained what they were going to do, provided information and did exactly what they said they would do. Gene’s bid was great, no hidden fees or surprises. He went out of his way to match the roof he was replacing on my external garage with the color of the roof on my house.
I highly recommend you giving them a call for your roofing and or construction needs/desires.

The crew did a great job! Our roof was in a state of disrepair and they really did an amazing job of helping us maximize our budget to really do our roof right. They were quick to respond, updated us along the way at regular intervals, super friendly and overall a joy to work with. I would highly recommend this business to anyone looking for this kind of work! Thank again!

Eugene and his crew were on time, and came quickly after our first conversation. They were able to complete the repair work and clean up in one afternoon. Did a great job, and supplied good information about the condition of my roof. Would recommend them to anyone needing roof repairs!

This is the 2nd time using Diamond Roofing for replacing our skylights. They are prompt and completed the job quickly without a mess or any hassle. Definitely recommend!!

Had Eugene out because someone we know used this company. We just wanted to see what the shape our roof was in. He was so very kind and checked everything and said we could go approximately 2 more years and did not lie and say we need to do right away like others. I’m positive when the time comes, this is the company we will use! They are A+

Eugene was super responsive and thorough with a request for him give us a quote/assess for potential damage on my townhouse rooftop deck. He was honest in his assessment of our rooftop deck not needing any repairs and super helpful in educating us on what to look out for.

Eugene at Diamond Roofing has become our go-to recommendation for anyone needing roofing work. Our customers always have great things to say about him—he’s professional, easy to work with, and his work speaks for itself. He’s reliable, gets people scheduled in a reasonable timeframe, and always delivers quality results. We wouldn’t hesitate to recommend him to anyone looking for a trustworthy roofer.

I’ve referred quite a few of our customers to Eugene at Diamond Roofing, and the feedback has been nothing but positive. Everyone comments on how smoothly the process goes and how professional and friendly Eugene is. He consistently does great work and gets people scheduled within a reasonable time, which we really appreciate. It’s always a relief to know that when we recommend Eugene, our clients are in good hands.

We just had our roof replaced by Diamond Roofing & Construction for our home, and I am very happy with the results! The team was professional, efficient, did a thorough work from start to finish, and the crew was very respectable to my home, and left my place immaculate after the work was completed. They used high-quality materials, and the workmanship was excellent. The price for a new roof is reasonable and there is no hidden cost. I want to call out our project manager Eugene, who not only kept us informed on every step of the project, but also made sure the project is completed on time and within budget. I definitely recommend Diamond Roofing & Construction for anyone needing roofing services. Thank you for an excellent job!

We've had the pleasure of working with Eugene and Diamond Roofing on two roofing projects over the past few years. Both times, we've been thoroughly impressed by them -- their quotes were competitive, their communication was timely and clear, their workmanship was excellent, and their cleanup immaculate.
We highly recommend Diamond Roofing for anyone in need of reliable and high-quality roofing services!

Eugene did a tremendous job on our roof!! It wasn’t your typical reroof. His crew had to replace a lot of plywood and fix rotten roof joist. Most impressive is they did the job in less than a week !! I’ve been in construction for 30 years and have seen alot of good and bad. Diamond Roofing if definitely one of the good ones !!!!

Diamond Roofing installed a new roof for us and we had a super positive experience end to end. Clear communication, high quality workmanship, and a fair price. Would recommend to anyone needing roofing services.

They are very professional. and Eugene was very careful, knowing that I was not there, and would take the initiative to send me pictures to see the progress of every step. Saved me a lot of time

They Did an excellent job with everything. The estimate, the explanation of the work, the installation and clean up after all the work was done. They Completed work in a timely matter (quicker than I expected) and resolved any issues I had, Roofing guys were great.Definitely would recommend going with Diamond roofing !

To hire a roofing contractor, start by researching local companies with good reviews and proper licensing. Request quotes from multiple contractors, verify their insurance and certifications, and ask for references. Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.
Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.
When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.
Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
