We use a safe, professional-grade treatment to kill existing moss, followed by gentle manual removal to avoid damaging your shingles. To prevent regrowth, we can apply a zinc or copper-based strip near the roof ridge. These strips release ions with each rain, creating a protective barrier that inhibits moss and algae for years, a crucial step for our humid local climate.

Yes, flashing corrosion is a frequent and serious issue in Mount Joy due to moisture and temperature swings. Corroded flashing loses its watertight seal, leading to leaks in your roof valleys, around chimneys, and near skylights. We inspect all flashing points, remove the compromised material, and install new, high-quality aluminum or galvanized steel flashing sealed with premium caulking to ensure a durable, long-lasting repair.

We recommend a bi-annual inspection, ideally in spring and fall. Our check focuses on the areas most vulnerable to our local conditions: we look for early moss signs, check flashing for any corrosion or separation, clean out gutters to prevent water backup, and examine shingles for moisture damage. This proactive, local-focused approach helps catch small issues before they become costly leaks or structural problems.
