Thornwood Roofing & Maintenance has replaced 210+ roofs across Thornwood and Van Etten, Wyandanch, Bloomingburg, Churchville, East Durham. Every replacement starts with a full tear-off and decking inspection. We find the damage the old roof was hiding, fix it, and build a new system designed for NY weather conditions.
We carry certifications from GAF, Owens Corning, and CertainTeed, the three largest shingle manufacturers in the country. Our Thornwood 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.
