Rick Gregor – Owner, Gregor Roofing

Locally owned by a proud roofing industry veteran

Hi, I’m Rick Gregor, Owner of Gregor Roofing Company for more than 20 years. I have been involved in the roofing industry since I was 14 years old. I worked for my father, who was a general contractor, doing home remodeling work. We did all exterior renovations. I found myself most interested in the roofing work. After graduating from college with a degree in Business Administration, I worked for a major roofing manufacturer. For ten years I worked with roofing contractors advising their projects, and promoting roofing products.

We're the Best Local Roofing Company for the Pittsburgh Region.

Whether you require residential or commercial roofing in the Pittsburgh area, we’ve got you covered.

What Customers are Saying about Gregor Roofing

I was very happy with Gregor Roofing. Not only did I get a return call, they came out the next day and handled my questions and concerns. They were very professional and polite, and the follow up was great. I would highly recommend them!

From the outset, Gregor was over and above any other roofing companies we looked at. They were attentive through the quote process and unlike any others, they followed up. We were able to schedule an installation within a few weeks and the day they came, it was flawless. The team worked quickly and efficiently and everything was cleaned up perfectly the day they were done. The roof looks amazing and we couldn’t be happier with choosing them. Highly recommended!!!

Really impressed with the Gregor Roofing. They had a detailed plan and they executed this plan. Very professional and hardworking crew. My roof looks fantastic. They stayed until the cleanup was complete. We are 100% satisfied and we would HIGHLY recommend this company to anyone.

We had an amazing experience! Rick was extremely knowledgeable and his crew was as curtious as they were talented. From beginning to end the process was well communicated and efficiently handled. The new roof looks great! So glad we chose Gregor Roofing for our roof replacement!

Working with Staci and Rick from Gregor Roofing was an amazing experience! They really know the roofing industry inside and out, and they are able to help families secure their homes with the best roofing products and materials. They have a highly skilled and knowledgeable staff that provides information to each homeowner throughout the roof installment process. They did a great job with my families roof installment in Bethel Park, PA. I highly recommend Gregor Roofing.

We are so happy with our new roof thanks to Gregor Roofing! Every step in the process was made easy by Rick and his team. From the initial consultation and estimate, we were able to choose from a selection of high quality products from GAF Roofing, including the latest in solar shingle technology. The installation teams were polite, tidy, and worked efficiently to get the job done quickly. We recommend Gregor Roofing 100 times over!
