Highly recommend Three Rivers Roofing for roofing and more. My first experience with Ryan and his crews was in the summer of 2022. I had rain coming through my ceiling on 4th of July weekend. I tried multiple companies but I couldn’t get anyone to come out. However I had several companies contact me the following Monday. Ryan from Three Rivers Roofing was the only one that did not try to sell me a new roof. He said I had an issue with one of my chimneys and some of the surrounding shingles needed to be replaced. He gave me a fair price and incredibly quick turn around. The guys that came out were courteous and professional and quickly repaired the area. However the next time it rained it started leaking in a different area. Ryan’s crew came out found the problem repaired it and they did not charge me. Ryan said he guaranteed his work including the inspection and he is man of his word. When it is time to replace my roof I will definitely be using Three Rivers Roofing.

I had a couple of shingles that blew off my roof from the recent wind gusts we have experienced. I called Three Rivers Roofing yesterday and they were here first thing this morning. Ryan and his co-worker (sorry I did not get his name) were so professional and kind, it's a pleasure to know there are still contractors that are professional. They assessed my roof, reattached the shingles and caulked a couple of areas. Thank you so much for your quick turn around in responding to my call.

Ryan and his crew are super knowledgeable, responsive and professional. We have an old slate roof and Ryan’s expertise in specific considerations for that have been really helpful as well. His prices are reasonable/fair and I would highly recommend him!

I was extremely satisfied with my new roof and siding. I received high quality service with clear communication. They promptly returned and fixed a section of the siding that didn’t turn out the way I expected. The crew was always polite and left absolutely no mess around the exterior of the house. I received many compliments from both neighbors and strangers riding by my house. I would highly recommend their service.

I cannot recommend Ryan and his team at Three Rivers Roofing enough! They are hands down the best roofing company I have ever worked with. When I had a leak in one of the valleys of my roof, they were quick to respond, assess the situation, and offer a solution at an affordable price. Later, when a few tiles fell off my roof, they came out promptly to take care of everything and reassure me the roof was good shape overall. Ryan has always provided exceptional service for my family’s home, which is why 3RR is my #1 recommended roofer. If you are looking for a professional, affordable, and friendly roofer in Pittsburgh, look no further than Three Rivers Roofing! 5 Stars is not enough for this company!

We have an 80 year old tile roof that is still in good shape. We had a few tiles that were either broken, displaced or missing, so I contacted Three Rivers Roofing & Waterproofing. Ryan came out and reviewed all of the areas with me. He put us on their schedule, and a few weeks later the crew showed up and knocked out all of the work in half a day. Everyone I dealt with was very professional, and provided excellent service. I highly recommend them for your roofing needs.

What an amazing team! They truly transformed our home into our dream. The wrap around porch turned out even better than I originally imagined in my head! They showed up promptly every day, and continuously communicated throughout the project and will use them again for future projects! Thanks guys for being so awesome!

Ryan came and fixed a downspout issue we had. He was able to complete the job in no time at all and it looks great! We were able to schedule the work and have it completed in less than a week. Would recommend Three Rivers Roofing to everyone and I will be using them again!

I needed some gutter repair work done and called Three Rivers Roofing. Ryan and Justin came out on time, both were polite and professional. They fixed the problem on the spot. Very pleased with their work and would recommend them for your roofing/gutter needs. Ryan and Justin were awesome!

Professional, honest, and fair pricing. Three Rivers Roofing is always a pleasure to work with. Doesn't try to sell you work that doesn't need to be done and will actually advise against doing unnecessary work that other companies would try to upsell you on

Ryan and his team were very responsive in both coming out to provide a quote and answering any questions we had. The work was done very professionally and they were also able to address problems that came up along the way. Would definitely recommend to friends and family.

Ryan was so quick to respond to my request for a quote on a damaged covered porch fascia and soffit. When he came to our property to provide us with a quote and was professional and honest about the situation and provided a few options that would work. Ryan and his team came by and finished the work and did an incredible job! We couldn’t ask for a better situation. We will continue to keep his number for future roofing projects! 5/5!

Ryan inspected our roof and fixed a clogged drain. He responded quickly to my message, was punctual, friendly, and explained everything clearly. He was recommended to us by my neighbor who also had a great experience with Three Rivers Roofing. I definitely recommend him 1000%.

Found a gutter detached from my house this morning and called Three Rivers Roofing. Ryan quickly returned my call. He was in the area and able to stop by to look at the situation. Within 2 hours of my initial call the gutter was fixed. Very pleasant and professional to work with. I will definitely call Three Rivers Roofing for future roof/gutter work.

Ryan from Three Rivers Roofing happened to be working on another house on my street when we had been experiencing a leak from some damaged/missing slate. When I asked him, Ryan happily fixed my roof on the spot!! He was so nice! It looks great and the price was reasonable. We will be calling Three Rivers for all of our roofing and gutter issues!

They quickly were able to get a team out to fix a leak in my roof that several other roofers weren't able to repair. They were honest and communicative throughout the entire process - letting us know exactly what they were going to do and providing pictures of the work that was done. Affordable pricing and very nice team.

Al and his team once again helped us when we discovered we needed to repair our master dormer window tiles due to an interior issue. He responded immediately to my call and worked with the contractor so we could address the internal/external issues in a timely manner. Al is an expert, he’s honest and he values his customers. He is always my first call! Highly recommend.

Al and his team did a fantastic job replacing broken/missing slates on our roof, replacing our copper downspouts that had broken seams, and inspecting and resealing flashing around the chimney and plumbing vents. He was thoughtful in choosing our materials to keep the character and aesthetic of our old home. He appreciates good craftsmanship and it shows! They also helped to clear our gutters and be sure water was flowing to the street adequately. This was great timing because Ida rolled through a few days later and our home was water tight. Thank you Al and team!

Ted Kyle

Al was prompt and thorough. His team worked at it all day and even found an issue with a plumbing vent for me, so I could get a plumber out to resolve every possibility for a problem. I am grateful for their good and careful work on my old slate roof.

Al and his crew are very responsive and professional. I have been working with them for over 10 years. Their fees are always fair and explained well in advance. Recently, we had a leak in our family room and Al’s team took care of it. We have not had any problems since the work was done. The repairs were done seamlessly with our existing roof. One cannot tell that the work was done. I highly recommend Al and his team.

Al and the gang at Three Rivers Roofing are fantastic. I have been using Al for years and he has helped me on two different homes. The workmanship and the quality are excellent. Al is very straightforward and has always given an estimate that meets the final bill. I trust Three Rivers very much.

Three Rivers Roofing is THE BEST. When I had a bad roof repair from another company and had a bad emergency leak, they came out right away to fix the problem. Al, Paul, and their team are professional, thorough, and lightning-quick. I am confident in their work, their diligence, and their quality. If you are having roof issues, don't hesitate to give them a call. They came highly-recommended from my friends, and my friends were right! As a new homeowner who wasn't used to the Pittsburgh rains, my roof used to be a constant source of stress. I now have ZERO worries about my roof and recommend them to everybody I know. <3 them!

Al and his team were very professional and easy to work with. We noticed a small leak in our roof after the long rain last week. After reaching out to Three Rivers, Al got back to me the same day. He was able to diagnose our issue and get us a quote the following day. I don’t know much about roofs or home construction, but Al even took the time to explain what to look for and how to solve the leak. A few days later – Al and his crew finished the repairs and even repaired some other issues on our roof that we weren’t initially aware of. If you’re looking to get a job done quickly and right, I highly recommend Al and Three Rivers Roofing.

I would very much recommend Al and Three Rivers Roofing. I have a flat roof that was leaking into the interior of my house. I had several roofing companies over to look at the roof and provide a quote to fix the leak. The solution for each company was to resurface the entire roof without even attempting to find where the leak was coming from. All the quotes I received were between $8k and $14k. Al responded to my call and was able to stop over the same day. He took the time to actually look for the leak rather than trying to sell me on an expensive roof replacement. He identified the leak source within minutes and filled the hole with rubber sealant FREE OF CHARGE! After the next few days following some heavy rain, Al called and followed up to make sure that the leak was fixed, it was. After confirmation, he stopped back over to put a permanent patch over the hole. He even patched over some other spots and seams on the roof that weren’t leaking, but could potentially cause some issues in the future, without me even asking about them. Total cost for the repair was under $200 vs the $14,000 quote I received from other companies. Incredibly happy with Al’s repair, promptness, and professionalism. I cannot recommend him enough!

We highly recommend Al and Three Rivers Roofing. Al stuck with us over a period of months and fixed every problem with our roof, even ones traced to the work of an earlier contractor. We own a wooden Victorian house from the 1890s, with a steep asphalt shingle roof, located at the top of a high hill in Pittsburgh. Shingles kept blowing off in the wind and we had a troublesome leak. Al figured out every problem and solved it. He personally got on our roof and discovered three nails improperly placed and told us this was the cause of our leak. We did not believe it at first, but sure enough, after Al fixed the nail problem we have not had a leak. He also developed an attractive solution to an inadequate original copper gutter. Al is a great diagnostician of roof issues.

Al Lambert and his team are the best in the business. Over the years, they have installed seamless gutters on my home, repaired my existing roof, installed a rubber roof on my porch and more.
Al will not compromise when it comes to the quality of his work. The attention to detail is great and they are highly skilled when it comes to the job they do. They clean up the worksite when complete, and the overall experience with Three Rivers Roofing is nothing short of fantastic.
As a small business owner myself, I appreciate great service, a quality product and reasonable pricing. In my opinion, Three Rivers Roofing is the best in the business; I wouldn't go anywhere else, and have recommended them to my neighbors as well.

Three Rivers Roofing was referred by somebody else in the industry. I am very happy for that referral. Al and his team were thorough and made sure the job was done correctly.

All took time to explain what went wrong and what his team did to correct it. They're my first call for roofing going forward.

We have a tile roof and there was a leak; contacted Al who responded immediately and scheduled a visit to provide an estimate. He was very well versed with our issue and actually had worked on my home with previous owner! We received a few other estimates which were double the cost. Al explained that our roof is in great condition but the valleys needed some updates. His price was fair and his colleagues did great work. They were punctual, professional and tidy. We will continue to contact Three Rivers for our roofing needs and highly recommend them.

Al was quick to respond to my inquiry, within 24 hours. Came out within same day to view and assess the roof and provided written estimate on the spot after discussing what he felt the issues were causing the leaks. Very knowledgeable about slate roof and repairs. Job was started in same week. He stopped by while workers on site to check in and make sure all was going as planned. Provided photos of the before and after. Didn't just try to sell me a new roof like others have done before. Was clear in telling me what I needed and what I didn't need to do with the roof. I will be using him for all/any roofing needs and fully recommend him and Three Rivers Roofing!

We used 3 Rivers Roofing for many projects over the past 8 years. Shortly after we purchased our home in 2007 we realized that we had chronic roof problems in many different areas, especially around our stone chimney. We had 2-3 roofers do repairs and got countless other estimates. No one was able to diagnose or fix the problem...until we found Al at 3 Rivers Roofing. Not only did he solve our roofing problem that no one else could, but he also guaranteed his work. We have referred 3 Rivers Roofing to 2 neighbors to fix other complex roofing problems. They were able to fix their problems as well. We found out the hard way that there aren’t many good roofers out there. We’re glad we found this company!!

Al is a great guy who is very knowledgeable about roofing. He replaced broken tiles on my roof and showed me how to do it myself for the next time. Good guy and hardworking team!

I have had Al Lambert and his Three Rivers Roofing crew perform various and multiple roofing jobs both large and small over many years on the 1920s French Tile Roof of my home. This man is the totally professional, highly ethical roofing expert you pray you find when you need a roofer. Al has personally showed up on EVERY job his company has ever done to ensure the work was done to my satisfaction. This is the standard to which every contractor should be held. The "Al Lambert standard" shows he cares about the customer, is ethical in his business dealings and that he understands the value of having a customer be able to confidently refer others to his business. Al and his team are the only roofer I use. Don't waste your time with other roofers- just call Al at Three Rivers Roofing.

Awesome service. Agree with the others here that say they would not trust anyone else with their clay / slate tile roof. They even had tile to replace the broken ones that were a perfect match for my rare, 50 year old tile. Lifesaver!

I had a bunch of leaks in my tile roof. Al came out, went up on the roof, and took pictures of everything he found. He found the same things and then more compared to the two other companies I had look. Needed to replace the valley flashing, a bunch of broken tiles, etc. We went into the attic to verify where leaks were getting in with what he found on the roof. I knew nothing about tiles roofs, and he explained the differences with a tile roof that would help with avoid damage in the future.
Soon after the crew came out and started working on my roof. Al sent pictures of everything they fixed. It was nice to see before and after pictures so I know what was actually done to my roof. I was informed of everything that was going on.
Been a couple weeks now and have zero leaks. Went into my attic to confirm as well. All in all a good experience. Al's a good guy that I trust isn't going to screw me over. Would recommend!

Three Rivers Roofing has been great to work with on numerous occasions. We have a house that's nearly 100 years old with a tile roof. The prior owners did not maintain the roof as well as they should have. TRR has done a great job with a few repairs since purchasing the house and their work has been of high quality each time. Al has been very responsive, thorough in explaining each issue and resolving it each time. I would highly recommend this contractor.

Gave Al a call on short notice for fascia installation following a home inspection. It was an extremely complicated job which I had been told by other roofers would be nearly impossible due to closeness of my neighbor's house. Al came out the same day I called to take a look and had a crew on site Monday morning. Really exceptional responsiveness and knowledge that's hard to find among contractors. If you need a job done well and are looking for someone who stays in touch, these are your guys.

I've worked with Al and his crew on several occasions. He's ALWAYS responsive and gets the job done when he says he will. Al and his crews do the job right and get it done in a timely manner. I've had nothing but good experiences and will continue to call Al for any roofing needs!

Al and his team were great! We had them fix our roofing issues. They take pictures of the issues and then when it’s fixed so you have great documentation. They were prompt and came in right on budget. I would highly recommend them!

Great service from Al and his crew. Always responsive and goes above and beyond to get the job done. Other roofers told us we needed a new roof for over 10k. Three Rivers said the roof just needed maintenance which saved us hugh

Very poor experience with Al and Three Rivers Contracting. I recently hired Three Rivers to fix a roof leak that was allowing water to enter my home. I’ll provide a very detailed account of the experience below for people who are considering hiring Three Rivers Contracting, but the short version is they told me it would cost $3,650 to fix the water issue. They completed the work but the issue is completely unresolved. Three Rivers Contracting and Al refuse to address the issue and have taken my money without doing what they were hired to do.

I called Al to discuss getting a quote for a roof leak that was allowing water to enter my main bedroom. Al was kind and prompt in setting up a time to inspect the roof and provide a quote. About a week later Al stated he had gotten up on the roof and suggested some repairs that would cost between $3500-$4000 depending on the final cost of materials. I asked if this would resolve the water issue (as this was the entire purpose of getting the work done) and Al said it would. A few weeks later I called Al back and agreed to hire him for the job.

Al wasn’t able to start the repairs for a few weeks because of rainy weather in the area, which was understandable. A few days later I sent Al photos of the damage the water was causing inside and asked if he knew where we were in terms of scheduling because the water damage was getting worse. Al said we would be the next job as soon as there is a clear day and even provided a couple of suggestions to mitigate the water damage in the meantime. It’s clear that the only reason I was getting the work done was to stop the water leak. As promised, a worker came by a few days later and completed the work. The work took less than a full day. Al came by the following day to pick up a check for the work and said we should be good to go and to call if there were any issues as the work comes with a 1-year warranty.

After the next rainstorm I noticed water still coming in all of the same spots as before. I sent Al a text message to let him know the issue was still happening and he gave me a call to discuss. Al advised there could be issues with the siding or maybe an issue with another totally separate portion of the roof. This was quite a surprise as this was NEVER mentioned before. The job was sold as $3,650 to fix the water leak, NOT $3,650 and it might fix it, it might not. I don’t know anything about roofs so I trusted what Al told me. Al then went on to tell me the contractor who remodeled the house prior to me purchasing the property should fix this and I should take it up with them or the home inspector? He went on to say he hates working on these “flip” homes because they are all junk, etc. Maybe that’s true, I don’t know, but why would you not review this before agreeing to the job. Instead they took my money and didn’t fix the problem. Three Rivers has been extremely unaccountable and have done nothing but blame the previous owners of the home and home inspector. I don’t understand how this is relevant since they were hired to fix the leak and they didn’t fix the leak at all. Now I’m out thousands of dollars and have to find someone else to fix the leak. Absolutely awful experience. Avoid at all costs.
