First Source Roofing & More | Roofing Services in Dayton, OH 45414

In Dayton, heavy rain and seasonal freeze-thaw cycles can overwhelm or damage the flashing in roof valleys—the critical channels where two roof slopes meet. Our repair process starts with a thorough inspection to locate the failure point. We then carefully remove old, compromised materials, install new, corrosion-resistant flashing sealed with premium waterproofing, and ensure proper integration with your existing shingles. This targeted repair restores the valley's ability to safely channel water away from your home.

Yes, skylight leaks are a common issue we address. Leaks often occur due to failed or shrunken sealant around the frame, cracked flashing, or improper original installation that doesn't account for Dayton's wind-driven rain. We don't just re-caulk; we perform a complete diagnostic to identify the root cause. Our repair typically involves removing the surrounding shingles, installing new step-flashing integrated with the roof deck, and applying high-performance sealants to create a watertight, long-lasting seal specific to your skylight type.

It can be tricky! While water stains on your ceiling are a clear sign, the leak's origin is often higher up. A leak directly below a skylight usually points to its flashing. Water stains running down an interior wall or appearing away from fixtures often trace back to a compromised roof valley. The best course of action is to call us for a professional inspection. We'll safely access your roof, track the water pathway, and give you a precise diagnosis so we can fix the right problem the first time, saving you from repeated repairs.
