Roof Leak Causes Explained

Why roofs leak, from failed flashing and pipe boots to missing shingles, clogged valleys, poor ventilation and condensation.

Most roof leaks come from a short list of causes. Flashing around chimneys, walls and skylights fails or was never installed correctly. Rubber pipe boots crack in the sun. Shingles are missing, cracked or lifted by wind. Valleys wear or clog with debris. Nail pops and exposed fasteners let water in. Gutters back up and force water under the edge of the roof. Ventilation problems can cause condensation that looks like a leak.

Water travels, so a ceiling stain may be far from the opening in the roof. Finding the source takes an attic inspection and a careful look at the roof surface and penetrations. In Nashville, heavy storms and humid summers make small problems worse quickly. We explain what we look for, photograph what we find and recommend targeted repairs, and we tell you when the roof is simply worn out.
