    Asked for a full replacement roofing quote. Estimator came out checked the roof and never followed up with a quote. Have called 3 or 4 times and still no quote for 3 weeks.

    Buyer beware! We received work on our clay tile roof. They did the work but they over charged by at least 2000 dollars. I think they are good roofers but beware of you have a difficult roof to work on.

    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 s

    If I could give less than 1 star i would. He stops out for an estimate and DOES THE JOB without consulting. NEVER call again!! Buyer beware!

    Ryan and his crew at Three Rivers Roofing did a great job replacing my roof. It looks like a new house. Attention to details from start to finish. The cleanup was like they were never here. I highly recommend them for any roofing needs. Couldn't be happier.

    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 …

    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 …

    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!

  • 5 out of 5Ed Sauera year ago

    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!

  • 5 out of 5Aaron Thomas2 years ago

    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!

  • 5 out of 5Larry2 years ago

    We have used Three Rivers Roofing twice and were pleased with the price and the experience both times.

  • 5 out of 5Chris Myer2 years ago

    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!
