BML Contracting | Roofing Services in Lancaster, NY 14086

In our area, the most common cause is failed or deteriorated flashing—the metal sealing around the base of the chimney. Harsh winters and temperature swings in Lancaster can cause the metal and sealants to crack and pull away. We fix it by carefully removing the old flashing, inspecting the underlying structure, and installing new, custom-fitted flashing with durable, waterproof sealants designed for our local climate to ensure a long-lasting seal.

Moss is more than an eyesore; it traps moisture against your shingles, leading to rot, granule loss, and a shortened roof lifespan, especially with our damp springs and falls. We safely remove moss using specialized, eco-friendly cleaning solutions that kill the growth without damaging your roofing materials. More importantly, we identify and address the underlying cause—often shaded areas or clogged gutters—and can install zinc or copper strips to prevent future regrowth.

Keep an eye out for local warning signs. Externally, look for cracked or rusted metal around chimneys, vents, or skylights, or visible gaps where the flashing meets the roof or masonry. Inside your attic after a rain, check for dampness or water stains on the sheathing or rafters near the chimney. If you notice any of these signs, it's time for a professional inspection. Catching flashing issues early here in Lancaster can prevent much more extensive and costly interior water damage.
