Jms Roofing Pros | Roofing Services in Bethlehem, PA 18018

In our Bethlehem climate, the most common cause is failed sealant around the skylight frame or cracked flashing. Moisture and freeze-thaw cycles break down these materials over time. We fix it by carefully removing the old sealant, inspecting and repairing or replacing any damaged flashing, and applying a new, high-grade waterproof sealant designed for our local weather conditions to ensure a long-lasting repair.

Corrosion is frequent due to our area's humidity, winter salt exposure (from road treatments), and acidic runoff from older roofing materials. We offer replacement with more durable, corrosion-resistant materials like galvanized steel, aluminum, or copper. During replacement, we also ensure proper integration with your existing shingles or tiles and apply protective coatings to significantly extend the lifespan of your new flashing.

Look for water stains on ceilings or walls that correspond to roof penetrations like chimneys, vents, or where dormers meet the main roof—these are classic signs of flashing failure. If the leak appears directly under a skylight or after heavy wind-driven rain, flashing is often the culprit. The safest approach is to call us for a professional inspection; we can pinpoint the exact source from the attic and exterior to recommend the right fix for your specific home.
