Roofing, Siding & Windows in New London County, CT
Cooper Modifications is based in Milford and takes select projects east into New London County, including the shoreline around Mystic, Stonington, Groton, Waterford, and Old Lyme, and inland toward Norwich. This is farther from our shop, so we're upfront: call us and we'll tell you honestly whether we can take your project and when.
Your Trusted Contractor in New London County
Southeastern Connecticut's coast
The New London County shore sits at the eastern end of Long Island Sound, where the Connecticut coast's wind-borne-debris zone runs from Madison to Stonington. Homes here take strong wind, salt air, and flooding. We build with high-wind roofing, corrosion-resistant flashing and fasteners, and gutters sized for coastal storms.
What we do here
Roofing (asphalt, metal, slate, composite, copper), fiber cement and vinyl siding, replacement windows, gutters, and doors, on a project basis. For larger jobs where a trip east makes sense, we can run roof and siding together.
