About Our Denton Texas based roofing company

Our roofing company started with our founder, Dan Gillean. Years ago, Dan worked with his father as a general contractor. While he was working on businesses and homes, he realized that people’s roofs were often falling apart without the property owner’s knowledge. To help businesses and homeowners alike, he started Gillean Brothers Roofing, LLC and began fulfilling roofing repair and roof replacement needs in the greater Denton area.

Since our start in 2017, our roofing company has grown to exceptional heights! Dan now works with his team to provide Denton and the surrounding areas with roofs they can count on. From small leaks to roof restorations, our family-owned and -operated company can do it all. We even help with your home insurance claims!

Joe Currin, sales representative for Gillian Brothers Roofing, along with his crew were phenomenal with our roofing and fence needs. All were professional and honest!!! The main factors … More were skilled handling of our insurance claim, very precise but fast with installation of shingles and a very thorough cleanup. Joe’s crew also fixed our fence and stained it. I would definitely use them again!

I can't say enough great things about my experience with GBR, and Joe Currin. Probably the most professional company I have ever had doing work at my home. Joe was very clear and specific … More with his communication on all work to be performed. He was extremely consistent with keeping me up to date with scheduling and any changes. There were never any surprises during the entire process. The workers took unbelievable care to protect my property during the process. GBR uses high quality materials and they're employees are friendly and professional. I highly recommend GBR and Joe Currin to anyone in need of roofing repairs.

After dealing with a persistent roof leak for six years — and hiring six different roofing companies who were unable to fix it — I was beyond frustrated. Then I found Gillean Brothers Roofing, … More and they solved the problem.
From the very beginning, Joe and the team took the time to thoroughly inspect the issue instead of offering a quick patch. They explained exactly what had been missed before and provided a clear, honest plan to fix it correctly. Their professionalism, expertise, and attention to detail were on a completely different level.
The crew was punctual, respectful, and meticulous with their work and cleanup. Most importantly — the leak is finally gone!
If you’re tired of temporary fixes and want a roofing company that truly knows what they’re doing, I highly recommend Gillian Brothers Roofing. They delivered results when no one else could.

After noticing water dripping from my bathroom light fixture during the recent ice storm, I contacted Gillean Brothers Roofing. Joe responded promptly, but the dripping had stopped before … More he arrived. Although it appeared there may not be an issue, Joe followed up a few days later once the ice melted and inspected the roof. He found no issues and assured me no repairs were needed. I appreciate the honesty and professionalism of Joe and his team and would highly recommend their services.

This is a great roofing company! They have fixed my dead valley leak in my roof.a couple years ago. Also came out today to remove ice from the ice dam that caused water to move up under … More shingles. Very prompt and very courteous. I first tried them after a recommendation I had a couple years ago. I dealt with Joe. Thanks for listening and the great service and the advice about better guttering I would recommend them if you need a new roof or repair.
