Thanks once again to the Roof Dr. Team. David and Freddie worked hard in the summer heat and did an extensive and detailed job repairing some damaged wood along the fascia and soffit.

When I need a new roof in a few years, they will certainly be my first choice.…

I needed a part replaced. They offered a quick turnaround had it repaired in the same week. We missed getting a birds nest though so they came back later in the day to remove it and put the roof bits back together. Great service! I do recommend them!
