Gomes Sheet Metal | Roofing Services in Salem, MA 01970

In Salem's damp climate, excess moisture is the primary cause of algae and moss growth. Our moisture control installation creates a properly ventilated and sealed roof system. This manages attic humidity and prevents the condensation that creates the damp environment these organisms need to thrive. By controlling moisture at the source, we stop the problem before unsightly stains and damaging growth can take hold on your roof.

Absolutely. We first repair the compromised waterproofing layer—whether it's flashing, sealants, or membrane—to stop active water intrusion. Once the structure is dry and protected, we address the resulting moss or algae stains. Our approach ensures the root cause (water damage) is solved, preventing the issue from quickly returning, which is common when only cleaning the surface stains.

Salem's historic and older homes are especially vulnerable. Over time, waterproofing materials degrade, allowing small amounts of water to seep in. This constant dampness behind walls or under shingles is the perfect breeding ground for moss and algae on the exterior and can lead to rot and mold inside. Our targeted repairs restore the waterproof barrier, protecting your home's integrity and preventing the moisture that fuels exterior biological growth.
