Once Over Roofing | Roofing Services in Rochester, NY 14624

In Rochester, chimney flashing leaks are often caused by the expansion and contraction from our freeze-thaw cycles, which can crack old caulk or loosen the metal flashing. We fix this by carefully removing the compromised material, installing new, heavy-duty step flashing that's properly woven into the shingles, and sealing it with a high-grade, flexible sealant designed for our climate to create a durable, watertight seal.

Roof valleys act as gutters on your roof, channeling a large volume of water and snowmelt. In our area, heavy snow and ice can cause wear or damage the valley lining. Our approach involves a thorough inspection to assess the damage. For a lasting repair, we often install a new, wide metal valley liner (like copper or galvanized steel) that provides superior protection and water-shedding capability, tailored to handle Rochester's specific precipitation challenges.

The signs can be similar: water stains on ceilings or walls, especially after a heavy rain or during snowmelt. A key local tip is to check in the attic after a weather event. Shine a flashlight along the chimney chase or where roof planes meet (the valley). Look for moisture, dark water stains, or drips in these specific areas. If you see this, it's time for a professional inspection from a roofer familiar with Rochester's common leak points.
