McCann Roofing | Roofing Services in Drexel Hill, PA 19026

Moss is common here due to our shaded, humid conditions. We start by safely removing existing moss to prevent further damage to your shingles. Then, we apply a specialized zinc or copper-based treatment at the roof's ridge. This creates a protective strip that inhibits future moss growth with each rainfall. We also recommend trimming back overhanging tree branches to increase sunlight and airflow, which are key to keeping your roof moss-free.

In Drexel Hill, flashing around chimneys, skylights, and vents often fails due to temperature fluctuations, aging sealant, or storm damage. This separation is a major cause of leaks. Our repair process involves carefully removing the compromised flashing, preparing the surface, and installing new, high-grade metal flashing sealed with premium, weather-resistant caulking. We ensure a watertight fit that accommodates the natural expansion and contraction of your roof, providing a long-lasting solution.

We advise Drexel Hill homeowners to do a visual check each spring and fall. Look for dark streaks or green patches (moss/algae), missing or cracked shingles, and any rust or gaps in the metal flashing around roof penetrations. Inside your attic, check for water stains, damp insulation, or daylight coming through the roof boards. Catching these signs early, especially after our variable seasons, can prevent minor issues from becoming major, costly repairs. When in doubt, give us a call for a professional assessment.
