Your roof protects everything underneath it, so when replacement time comes, you want it done right. Derwent Roofing & Maintenance removes the existing roof completely, examines the decking for water damage, and installs a new system from underlayment through ridge cap. Every component matters.
We carry certifications from GAF, Owens Corning, and CertainTeed, the three largest shingle manufacturers in the country. Our Derwent crews are factory-trained and your roof qualifies for the best warranties available, including GAF Golden Pledge with 25-year workmanship plus 50-year materials.
