J A Greenwood Roofing & Siding | Roofing Services in Derry, NH 03038

Yes, properly installed siding plays a crucial role. In Derry, ice dams often form at the roof's edge, causing meltwater to back up under shingles. We ensure your siding and roof edge (drip edge, fascia, and soffits) are seamlessly integrated. This prevents water from sneaking behind the siding and into the roof structure, addressing a common failure point during spring thaws.

Absolutely. A frequent culprit for skylight leaks in our area is failing or improperly flashed siding and trim around the skylight's curb. Wind-driven rain and snowmelt can penetrate these vulnerable junctions. Our siding repair and replacement services include meticulous re-flashing and sealing of the skylight surround with durable, code-compliant materials to create a watertight seal and stop the leak at its source.

For Derry homeowners facing recurring moisture issues, a replacement is often the most reliable long-term solution. If leaks are frequent, or if your siding is warped, cracked, or has extensive moisture damage behind it, repairs may only be a temporary fix. We provide honest assessments and recommend full replacement with modern, weather-tight systems when needed to properly resolve underlying water infiltration that can lead to roof and structural damage.
