Most homeowners assume that if water enters the home, the roof itself must be leaking. While roofing problems are often involved, the source of water intrusion is not always caused by the roofing materials alone.

Over the years, we have inspected homes where the roof design itself created drainage and water flow problems. In one example, two roof valleys intersected too close to the edge of the roof, creating a flat section where water could not drain properly. Over time, the standing water caused the plywood decking to rot and created severe leaking issues inside the home.

Situations like this may involve several contributing factors. The architectural design may create poor drainage. The framing may allow water to collect in vulnerable areas. Roofing installation decisions may also affect how well the roof handles heavy rain, snow, and ice buildup.

At Casey Roofing Inc., we believe homeowners deserve honest communication about potential roofing concerns before problems become severe. When inspecting residential roofs, we discuss drainage issues, valley placement, ventilation concerns, and areas vulnerable to leaks or ice dams. Asking questions during construction or remodeling projects can help homeowners better understand how roofing systems will perform over time.

For this particular home, we removed the damaged plywood, reinforced the framing, repositioned the valley correctly, and installed updated underlayment, TPO membrane, and shingles to permanently correct the issue. Proper roofing repairs and design corrections helped restore long-term protection for the home.
