Certified Roofing & Exteriors

Certified Roofers put vinyl siding on the three gables of our house. They did an excellent job in a timely manner and cleaned up after themselves. The gables are now well-sealed and they look great. The price was very fair, not overpriced like some of the other estimates we initially got. Great job and highly recommended!

These guys we're Aces, Fast and professional. Cleaned up after all said and done. Didn't know they were here. Except the new roof of course.

Had Mark and his crew do my roof..very efficient and professional..did an amazing job..they were extremely great at cleaning up ..great company to work with...

These guys are great. From the moment Mark and Sean came to take a look and come up with a solution to the organization and cleanliness of the job. Highly recommend certified roofing!

After a wind storm I had my entire roof done by Certified Roofing. I’m probably one of those homeowners who are annoying but genuinely care about a contractors quality of work. I own a home that was built in 1919, and I feel like it deserves the absolute best so it can last another 100+ years. From start to finish Mark was there, he answered every question and had no problems going above and beyond when I asked for it. The prices were fair and the employees were top notch. Shawn, Tyson and Phoenix were absolutely the best guys you could ask for and I wouldn’t hesitate to hire them again.

Had some shingle damage on our home due to high winds. Called Certified Roofing ....and 3 other companies. Certified had a Roofing tech out within an hour. Highly recommend you give them a call! Thanks again for the quick repair.

Just an excellent experience from beginning to end. Mark responded very quickly to my inquiry and the work was done within a few days. His team is professional, friendly, and explained the work very clearly. We are very pleased. Thanks so much.

Not satisfied with the work. Roof still leaking. He informed that shape of roof is such that it will leak when more rain. My view is that he should not had accepted the assignment unless sure that it can be repaired. Instead of doing needful he advised to replaced the entire portion of roof. This advice should have been given at the initial stage. Resulting had to call someone else to do needful. It was found that the lower portion of shingles was not properly fixed and left over shingles portion and screws were lying in the valley. Actually I feel disappointed with his work and commitment.However wish him well and happiness with the request to do work accurately. Thanks.
Hello. i am still of the view that you have done my roofing as should be. The procedures of a dead valley roof should have been adopted rather than old traditional method you adopted. you were clearly informed that water is leaking in the area where two roofs are joining. i think it's should be covered under the warranty that you have given.
kindly look into it and do needful under warranty and no payment.
I just went with the reply of owner of certified roofing's. No doubt they may be professional but I am concerned with the work done on my house.
Firstly, before taking the quote, I have shown them the valley ( joint) from where it is leaking and also showed from inside. He confirmed that the issue will be solved and gave him 2000$. for the work. If I agree with him that the roof was not properly designed and the problem cannot be resolved, then should have not accepted the job. However, when he opened the roof and according to him there was some leaking from top. which according to him has been repaired. He didn't touched nor repaired the actual problem. He being a professional doesn't know how to do dead valley end. He satisfied me that the work has been done and balanced payment was made. after few days during rain, the roof was leaking from same place and also from downpour. I called him and informed. he visited and started making excuses and that the roof was not properly designed . Ok. then in my view was that he shouldn't have accepted the work. He shouldn't have repaired.
This is no excuse but should have accepted his mistake, ignorance is not the solution, but learning goes with the age and experience.
However, I will not recommend anyone to get the job done from him. I don't like to write further as whatever losesI made cannot be recovered. Best wishes to future customers.the pictures attached is the after work is done by him.

Certified roofing replaced two skylights for me. Mark was excellent with addressing my questions and concerns and the crew did an excellent job. Thanks so much! I would definitely recommend.

I paid over $900 to fix a leak last year. This company replaced the board and the shingles on 4x8 area. Replaced a vent but the leak happened at the vent because bad quality workmanship. A new company sent proof that less amount of material used around the vent. I reached to this company first but they did not even send a person to check even after multiple followup. Warranty is worthless for this company.

Great service. Did a wonderful job and it was done in a timely manner. Would highly recommend and would work with them again.
Thank you!

Mark and his team have done a wonderful job anytime I have called them to do work on my house . Highly recommend them .

This was our first encounter with Certified Roffers. Mark and his team responded swiftly and did an excellent job!!!
Perfect combination of great work ethic, polite and skilled from Mark and his team! No mess left after either. We will hire them again and recommend this company to everyone!

Certified roofing did an amazing job on my garage roof, they gave me a time and date and actually did the job and week early, the 2 young guys that did the work, did a great job they kept my property clean, when they were completely finished, I went looking for roof debris and nails, found nothing. Choosing Certified was probably the best decision I've made for an asphalt roof.

We had an issue with our roof around the old brick chimney , Mark came out right away to have a look.
He applied a temporary patch and gave us a quote to remove the old brick chimney and replace the roof.
Very fair price and excellent workmanship , our new roof looks excellent and it’s nice the chimney is gone.
Thanks Mark.

Mark and his worker Phoenix did a great job at assessing where my leak was originating and repairing the area abutting the chimney in a timely manner, after the first contractor did a very poor job and didn’t fix the leak. Very personable and cleaned the site after the repair. Also provided pictures for completed work. Wouldn’t hesitate to call on them again when needed for future jobs.

I called Certified at noon and they arrived at 2:30 and completed the repair buy 3:30.
I was and still am very satisfied with there work.

I enjoyed dealing with the owner of Certified Roofing Windsor they were very professional and pleasant to deal with them I would recommend them any time.

Mark and his team did a great job of diagnosing and solving my leaky roof problem. They were fast and very responsive. Would highly recommend them for any roofing needs.

We got several estimates for our roof. A couple of companies went on the roof and left an estimate at the door. One did not get back to us. Two emailed us highly inflated prices with financing information. Certified was the only company that spent time with us explaining all options. Mark left us a very reasonable estimate for upgraded materials as compared to the other estimates.

His team, a trio of personable, hardworking young men came as scheduled and did a good job. They cleaned the yard and swept for nails before they left.

We highly recommend this company and we have hired them since to install a chimney cap.

These guys are the best! Instead of upselling me an entire roof, the owner Mark explained to me that I just needed my caps replaced. Saved me thousands. I highly recommend this trustworthy company.

Mark was very professional and timely, throughout the process of replacing our roof. He listened to concerns, and responded quickly to all questions we had. Thank for the great workmanship Certified Roofing.

Mark and his guys did a great job at my house they were quick and cleaned up after themselves. I will use them again when I need any roof work in the future.

I highly recommend Certified Roofing to anyone wanting a professional job done for a reasonable price. I will be using them and recommending them to all my friends and family. Thankyou Mark and Sean.

After getting 3 quotes, Mark from Certified Roofing was the ONLY one who took the time to actually meet with me, climb up on my roof, take pictures, and give me a thorough inspection. He didn’t just tell me what needed to be fixed—he showed me the issues and explained why they mattered.

The quality of work has been top-notch, and his crew was super respectful throughout the whole process. Plus, Mark’s prices are fair, and he’s going above and beyond to make sure my roof is better than ever. If you’re looking for someone reliable, knowledgeable, and just genuinely great to work with, I highly recommend Certified Roofing. You won’t regret it!

Certified Roofing provided excellent service. They were fast to inspect the work needed to be done and they did a great job repairing the issues. I would definitely recommend this company..

Super nice owner and professional crew, got us in quickly for a roof leak. Fair price too. Would def recommend!

Mark and his team at Certified Roofing were wonderful to work with, from start to finish. Mark's focus on customer service was evident from the initial consultation at my house all the way through to the completion of my roofing project. Mark took the time to educate me on various roof shingle options, venting solutions, and sky light options, during the initial consultation and also provided me with the addresses of some of his recent roofing jobs to see some of the various shingle options that I was contemplating, which helped with the decision-making process. Throughout the installation, he and his wonderful team always kept the property clean and tidy at the end of each day. I couldn't be happier with the roofing job, including the ridge vent and skylights installations.

Great job on my roof. Guys were professional. Looks great too. Also nice that it doesn't rain in my kitchen anymore. Did a really good job cleaning up afterwards as well.

Mark and his team have twice done work and each time they have done a top notch job.....thanks ***** Five star rating and I will never use any one else in Windsor for my roofing needs.

Hi Mark! First things first. Tyson and Phoenix were amazing! Polite, respectful and incredibly hard workers. Even my next door neighbor commented on all of the above. It was a refreshing interaction and please thank them again for us. The job was done quickly and exceeded our expectations. We don't expect to need another roof, but we will definitely recommend certified roofing Windsor.

Mark and his team went above and beyond for my house. I asked them to do a repair and while checking it out he was more than happy to inspect my roof for any other damage. He gave me a very reasonable price for quality work and his team went above and beyond to do another separate repair they noticed during their work. Respectful, honest, and hardworking.

Saved from another rouge roofer. MIKE is a gem in the field. He was so amazing. His prices are not even what make him the best. Sent a nice employee to fix a mess we had been left with the last (claimed) roofer. We owe him still to this day. Knowing how many horrible roofers are out there he's a God sent. Made my kids feel safe again in their home. We can't thank him enough. Best by far.

We needed a new roof as we had a leak. We called Certified Roofing and they were very quick to respond and to come out look and give their opiniona and what options we could take and give an estimate for a new roof. Mark was very professional and knowledgeable and took the time to explain everything we needed to know and answered all our questions. His crew was as amazing as well early arrivals and worked all day as well very clean and tidy a great group of guys who are knowledgeable smart and answered all questions we had as well Mark has very talented group and we would definitely recommend Certified Roofing to anyone we know needs a roof Thank you so much and we couldn't be happier

Mark did two roof vents for me. One for kitchen hood and the other bathroom fan. Was happy with the work. He was proficient, on time, knowledgeable, and reasonably priced. So far, no issues. Will use agian in future. Thanks Mark

Mark (the owner) came to check out a leak on my roof in extreme freezing weather, when no other company would even take my call, and checked in weekly. In the end I didn't need a repair but he had no issues assessing weekly and checking in with me to reassure me. Highly recommend, great customer service!

We were in need of new skylights to replace old leaking ones and most of the companies would only do it if we replaced the whole roof. Mark from Certified came to our rescue and seamless replaced our old leaking with brand new Velux ones. They look great!
From outside Mark and his crew replaced shingles and fixed part of the roof seamlessly integrating new shingles with old like they were always there.

Thank you certified roofing!! They did a wonderful job. Mark explains everything during the consult and helps you decide on the perfect colour for my home! The workers were very nice and helpful and cleaned up. I would highly recommend this company!!

I had a great experience with Certified Roofing!. Mark and his team came through with an professional and reassuring experience that I would get a great roof. Thier attention to detail and doing little extras was a bonus.
I will be calling them again.

Mark and his team are good at what they do. He took his time to explain the whole process to me, helped me choose the best shingles for my roof, all at a fair price and even came back to help me fix my eavestrough for free. Am satisfied with the job they did for me. Would highly recommend them.

Thank you Mark and all teem for excellent job to fix my flat roof you deserve five star , very recommended

Mark and his team replaced the deteriorating capping on my roof. They were so fast, efficient and cleaned up after themselves. Mark and the job done earlier than our conversation. I will be calling him again when I need to replace my roof.

Mark and his team from certified roofing windsor were great!
The professionalism, the honesty, the price was exceptional. My roof was done in 1 day from start to finish and they do a great job at keeping your property clean while doing their work. I will definitely recommend them to any friends or family.

Highly recommend Certified Roofing. Mark went out of his way to seal a leak in our skylight, after hours and on a weekend. He also came back to place a tarp over it. They replaced the roof with exceptional quality. He is very honest, his crew was professional and went above and beyond to ensure a clean job site.

I had our leaking roof shingles, caulcking and improper metal covering and gaps around chimney work done through them this end of August 2023. Mark and his team are very knowledgeable, fair and honest.

Will update here after few rains on how things are. I would highly recommend Mark for getting your roof issues fixed

I had several roofing companies provide an estimate. For me, what stood out was not the price, which was very reasonable, it was how Mark spoke about his employees. He spoke highly of them. I can see why. They were early starting the roof, very courteous and professional. I would highly recommend Certified Roofing.

The owner contacted me and was very helpful, polite and not money hungry. He was genuine and actually wanted to help us and was not annoyed at answering our questions. Took his time with the job and got it done before our set date. I would highly recommend their service. Thank you.

Mark Elliott was timely in his response and gave us fair pricing and quality work. Sean was efficient and skilled in putting up our soffits after the heavy storm. I would highly recommend Certified roofing to do any exterior work to your home.

Took my call right away the day after a big storm. Came to my house to fix a leak same day as requested. Very professional and knowledgeable. Found the leak, performed surgery, fixed the issue and alleviated my worries as more storms were on the way.

The gentlemen were quick and efficient and friendly while repairing my roof after the storm. I would highly recommend their services.

I was very happy with the work. The workers were friendly and professional, and you can't even tell where they did the work. The person I was in contact with, Mark, kept in constant contact. Overall, a very good experience.

They are an honest company that are very busy and keep their promises albeit a little slow due to the volume of their work.
I would give them 4.9 out of 5 stars as they did their warranty work for me for free after regular hours.
A man of his word.
Mark went out of his way to patch an older section of my shingles

Mark and his team were extremely professional in the work they conducted and were there every step of the way answering our questions. Mark offers a wide arrange of products and delivered an affordable and reliable product for our price range. I recommend Certified Roofing to everyone looking for a new roof.

Mark has been so good to us replacing shingles over the years, that when we decided to redo the roof, we only contacted him. We are not disappointed. Our roof looks amazing & his crew is very professional & does good work. Any concerns we had were addressed immediately.
Mark also went beyond, searching for an antenna mount for us & then returning to install it.
We certainly recommend Certified Roofing.

Owner was down to earth, friendly, and aims to meet the needs of his customers. Very competitive pricing without ripping you off. Crew was kind, courteous, and hard working. Got the job done quickly without complicating the sale of my home. I will be contacting Mark again for my roofing/gutters/venting needs in the future!

Mark and the installers were knowledgeable, efficient and personable. Our calls and texts were responded to every time, and if we had questions or concerns they were handled immediately.

Cost was more than reasonable and the shingles look amazing…can’t ask for much more when doing a roof.

Thanks guys, it was a pleasure dealing with all of you…we’ll be sure to call you in 18-25 years when this one needs replacing

Glad to have found Certified Roofing Windsor for our roofing/ drainage repair and maintenance needs. Mark was extremely professional and patient in explaining the details of the service, and in providing guidance for continued maintenance. Top quality service! Will be using Certified Roofing for future work too. Was glad to have found from Mark that they also do renovation work. Thank you Mark for inspecting the basement space and providing suggestions and estimates. Will be looking to utilize their services for that as well.

We were very satisfied with certified roofing. The workers were professional and courteous. The roof is top quality at an excellent price. Would highly recommend this company.

Certified Roofing did an outstanding job on our cottage. They were punctual, hardworking and did a great cleanup job. Price was very fair. Thanks Mark Elloitt and crew. Much appreciated
