Marsen Roofing | Roofing Services in Rockland, MA 02370

In Rockland, our proximity to the coast means roofs are exposed to salt air and high humidity, which accelerate metal corrosion. Combined with our freeze-thaw cycles, this can cause flashing to weaken, warp, and pull away from chimneys, vents, and roof valleys. This separation creates openings for water to seep in, leading to interior damage. A professional inspection can determine if your flashing needs cleaning, sealing, or full replacement.

It depends on the extent of the damage. For minor surface corrosion, a thorough cleaning and application of a protective sealant may be sufficient. However, if the corrosion has caused holes, significant thinning, or the flashing is already separating from the roof structure, replacement is the only reliable, long-term solution. We use high-quality, corrosion-resistant metals like aluminum or coated steel to ensure your new flashing stands up to Rockland's weather for years to come.

Immediately. Even a small gap in your flashing can allow a surprising amount of water into your attic, walls, and ceilings, especially during our nor'easters and heavy rains. This moisture can quickly lead to mold growth, wood rot, and compromised insulation. If you notice leaks, water stains, or visible gaps around your flashing, contact a professional roofer right away. Prompt repair is far more cost-effective than dealing with the extensive structural damage that can follow.
