Sen Roofing | Roofing Services in Londonderry, NH 03053

Properly installed and maintained siding is a critical first line of defense. It directs water away from your roof's edge and walls, preventing ice dams and moisture from backing up under shingles—a common cause of leaks after snow melt. Our siding services ensure a tight seal that protects the vulnerable areas where your roof meets the walls.

In our cold winters, a clean chimney allows for proper ventilation of combustion gases and moisture. A blocked or dirty flue can cause condensation and ice buildup inside the chimney structure, which can lead to interior leaks and damage the surrounding roof flashing. Our sweep service helps maintain the integrity of your entire chimney and roof system.

Very likely, yes. In Londonderry, the freeze-thaw cycle is tough on roof flashing—the metal seals around chimneys, vents, and valleys. Flashing can separate or corrode, creating a direct path for water. This is a frequent local problem we address. We repair or replace compromised flashing with durable materials and expert techniques to create a lasting, watertight seal.
