James Nelson Roofing | Roofing Services in Rochester, NY 14615

Rochester's harsh winters and frequent freeze-thaw cycles are tough on roofing materials. Chimney flashing, the metal seal that connects your chimney to the roof, constantly expands and contracts. Over time, this movement can break the sealant, loosen fasteners, or create gaps, allowing water to seep in. We see this often and address it with durable, properly installed flashing tailored to our local climate.

Safety and integrity come first. If we find soft or rotted decking (plywood/OSB) during an inspection or repair—a common issue here from undetected moisture—we will clearly explain the extent to you. The damaged sections must be replaced to provide a solid, safe base for new shingles. Leaving rot in place compromises your entire roof structure and voids material warranties. We ensure the new decking is properly secured and ventilated.

We don't just look for the obvious drip. In Rochester, a small leak often signals a larger problem like trapped moisture in the attic or compromised decking. Our repair process includes a thorough inspection of the entire roof system, especially common failure points like valleys, vents, and of course, chimney flashing. We find the root cause, fix it correctly, and help prevent the cycle of recurring leaks and hidden rot that plagues many local homes.
