Davis Roofing & Siding | Roofing Services in Perkasie, PA 18944

In Perkasie, the most common cause is failed or deteriorated chimney flashing. Our freeze-thaw cycles and heavy rains can cause the sealant to crack and metal to corrode. We fix this by carefully removing the old flashing, inspecting the underlying structure, and installing new, code-compliant flashing with high-quality sealants specifically chosen for our climate to ensure a watertight seal for years.

We use a low-pressure soft wash system with eco-friendly cleaning solutions. This method kills the moss and algae at the root without the damaging force of high-pressure washing, which can strip away protective roof granules. After cleaning, we can apply a zinc or copper-based treatment along the roof ridge. As rain washes over it, this creates a protective zone that inhibits future moss growth, which is especially helpful in our humid Pennsylvania climate.

Look for water stains on interior ceilings or walls near the chimney or roof valleys, especially after a storm. Outside, check for visible rust, cracks, or gaps in the metal flashing, or spots where the flashing has pulled away from the chimney or wall. If you see granules from your shingles accumulating in gutters near these areas, it's a sign of water runoff issues. We offer free, no-obligation inspections to give you a clear assessment and peace of mind.
