- "My roof was replaced yesterday and Gregor did a great job. Dillon was very attentive, professional, and a pleasure to work with. Everything was cleaned up. So nice to deal with a professional company that cares about the customer. Thank you so much for an awesome job."
- "Excellent service and work. Reasonably priced. Couldn't be happier.."
- "Gregor Roofing is a great company to do business with. The estimate was done by Rick the owner, and he stayed right on target. We had ventilation and leaking issues that Rick researched and specifically addressed. Rick’s crew was professional, courteous, and cleaned up each day prior to leaving. My neighbors commented on how hard his crew worked. The finished job was amazing and the final clean up immaculate. I would recommend Gregor Roofing over any other roofing company in the Pittsburgh area. A++"
- "Gregor Roofing We are happy with the roof and gutter service provided by Gregor Roofing. The new GAF shingles and Velux skylights look great. They also caulked the gutters and replaced damaged hangers. They did a thorough clean up afterwards and even used a magnet to make sure no nails were left in the grass. Rick and his crews were professional, friendly and a pleasure to work with. I would use them again."
- "The very very best experience with the roof and skylights install. Sergei, Dillon were both professional and respectful. Reliable in addressing our concerns. Great follow-up after install. We have had some crazy weather (tornado) after our install and they are very responsive about after-install follow-up. No leaks so far with this odd weather we have been having. Rick runs a great crew and business"
- "We just had our roof replaced and i highly recommend Gregor Roofing. We were going to be away for 4 days and we trusted them to do the job while we were gone. We told them the day we were leaving and they promised to begin that day and they did. They showed up before we left with an 8 man crew for our big roof. You hear about the tough labor market right now for hard work like this and yet they were all courteous, friendly and professional. The job supervisor went out of his way to make sure we would contact him with any concerns. They promised to finish the job in 2 days and they did despite the unusually high heat and humidity. When we got back into town, we had a beautiful new roof and there was absolutely no left over mess. Someone in the crew had actually watered the flower pots on our front porch!! If ever a business deserves a 5 star rating it is Gregor Roofing."
- "Gregor Roofing is an excellent company. Highly trained installers. And they stand behind their warranty. I had the roof replaced in 2013 by Gregor with an attic fan and gutters and downspouts. The roof, gutters & downspouts still look like new. The fan works hard during the Summer and I heard it making noise lately. I called Gregor to get a replacement and was surprised when I only had to pay $150 for the fan and $30 for shingles. That’s what I’m talking about!"
- "Gregor Roofing was a pleasure to work with. I felt comfortable from the initial consultation when Rick's experience showed through his ability to immediately assess the concerns and appropriate ways to complete my new roof installation. I walked through some additional concerns including gutters and downspouts, and he explained a solution for those as well. I had anticipated the work to start 6 weeks after the initial consultation, but was pleasantly surprised when they were able to get me scheduled in only 3 weeks. As luck would have it, it was on a day that I would be out of town, but Rick alleviated any concerns and said they could still start the work without me being at home and would keep in contact if anything popped up while I was away. I had family looking in on pets in my absence and they said the crew working on the roof were polite and friendly, and they had the bulk of the job done in a day! Ryan and Dylan then showed up three days later to finish up with the gutters, downspouts and vents. And the next day, we had a heavy downpour and everything was protected and worked as expected. Thank you Gregor Roofing for making this process easy. I love the new look, and the excellent warranty coverage that was included gives me peace of mind that I made the right decision!"
- "They are phenomenal! Very professional and timely in their work ethic and the project manager Ryan Ross was extremely helpful and always had time to answer my questions."
- "The crew did a great job. Sergei and his crew, showed up on time and were very responsive. They took pride in the work that they did and cleaned up daily and at the end of the job. Dillion checked in on the crews and also helped out if needed and they listened to what was requested. We had to let our dogs out at times and they worked around our schedule. They went above and beyond, working 12 hours the first day in the hottest day that we had had lately. I am extremely satisfied with the job completed by Gregor Roofing. I had 2 flat areas and 32 squares to be installed. They also installed a new skylight, drip edge, flashing, all new boots and roof venting. Highly recommend them for your roofing needs."
- "Great job.great price.Rick and Ryan both nice and professional guy."
- "I had a previous post where I complemented Gregor Roofing’s performance for a roof inspection on my house. Because of the great customer service, I decided to move forward with having them and install a new roof and gutters. I couldn’t have been happier with the service. They were responsive, calling and letting us know when they were coming. They cleaned up the property afterwards. When they had to leave the dumpster in my driveway for an extra day because of the Fourth of July holiday, the project manager called to let me know. The gutter installation was just as seamless. There are many disreputable roofing companies out there, but this is a second generation company that can be trusted to install the roof and finish the job properly, and you won’t need to worry about the quality of the service or the product."
- "Gregor Roofing did an excellent job and were very professional. They were attentive to all details. They truly care that you are happy with the finished job.....WE ARE! Rick has good people working for him. Ryan and Dillon did a great job overseeing our project....Sergey and his crew were very hard workers, and they all did a quality job. We would highly recommend Rick Gregor Roofing."
- "The roofing crew from Gregor Roofing was very professional. They showed up when scheduled, on time, and worked diligently throughout our roof replacement.. They organized & covered their supplies and cleaned up each day. They were all friendly, courteous, and respectful of us and our property. The crew did an excellent job and took pride in their workmanship. Overall, we are very pleased with our roof replacement and are happy to recommend them to our family and friends."
- "They were referred to us by our insurance agent. We are totally pleased with the workmanship and the professional attitude of the workers. We felt that we got a lot of value for the money, but more important. we felt that we got a great job. There were some challenges with ice in our driveway and roof and they worked around that. Clean-up was very very good. We were pleased so much that we have recommended them to friends and would use them again."
- "Excellent company. Did a full roof replacement including new plywood. Quick, courteous, and professional."
- "Gregor roofing company gave us a fair estimate. They were prompt and did good job replacing roof on our house. He wasn’t indifferent when we asked questions and made honest suggestions. We are satisfied with the job done. Would recommend this company to other potential clients."
- "I'm completely happy with their work. They are very friendly and professional. They are also very reasonable with their prices and very very easy to communicate with. One of the best companies I have ever worked with. Another plus is that, Rick doesn't subcontract the guys that put your roof on work for Rick."
- "Rick and his crew were prompt, professional and efficient. Their quote was competitive and they did a fantastic job on my roof. Rick was engaged with our project and very responsive; always called back promptly. The best testimonial I can offer is we had a small issue after the job was completed and paid, but Rick immediately responded and resolved the issue. Great work and service! Highly recommended."
- "Rick gave us a fair quote to do the work. So we hired him to replace our roof. Only took 2 days to tear off the old roof and put a new one on. The work crew were very professional. They are hard workers. I talked to the foreman on the job lots of times. He wanted to make sure I knew what they were doing and if it was alright with me. He was very polite. Gregor Roofing did my son's roof last year and he was pleased with the work. I would recommend this company with 10 stars!"
