J M Gangloff Roofing | Roofing Services in Hanover, PA 17331

Absolutely. While the roof valley is a critical point, proper siding installation acts as a vital secondary defense. At J M Gangloff Roofing, we ensure your siding is correctly flashed and integrated with the roofing system. This prevents wind-driven rain and ice melt from seeping behind the siding and into vulnerable areas like the roof valley, providing a comprehensive, watertight seal for your entire home.

Not necessarily. Often, skylight leaks in our area stem from failed flashing or issues where the roof meets the siding. Our expert siding repair service includes inspecting and resealing these critical junctions. We can often resolve the leak by repairing or replacing the adjacent siding and flashing, saving you the cost of a full roof replacement if the shingles themselves are still in good condition.

If your Hanover home's siding is old, warped, or has sustained widespread water damage from recurring leaks, replacement is the more reliable, long-term solution. New siding provides a solid, uninterrupted barrier. We install siding with modern water-resistant underlayments and precise flashing, which is especially crucial around roof valleys and skylights. This proactive approach stops persistent moisture intrusion and protects your home's structural integrity for years to come.
