Houston's subtropical climate with hot humid summers and mild winters drives most leak calls. Heat bakes asphalt shingles until they crack around pipe boots and skylights. Then sudden rain pours through those gaps and soaks insulation before homeowners notice ceiling stains. We check every penetration on roofs in the Heights and Midtown because those older homes often have single-layer shingles that hide damage until it spreads.
Cheap crews skip the moisture meter and just look for daylight. That misses wet decking under the shingles, especially around AC units where condensation drips all summer. Harris County requires a permit for any roof work that uncovers more than 25 percent of the deck, so we pull the paperwork before we start. We also pull back flashing at chimneys because that is the number one failure point on homes built before 1990.
We mark every wet spot on a roof diagram and give the homeowner a printed copy before any repair starts. This keeps surprises out of the final bill and shows exactly where new underlayment or boots go. In Downtown and near Minute Maid Park we see more commercial flat roofs, so we carry different probes for modified bitumen and TPO seams that split from UV exposure.
Call 713-555-0199 today if you see brown water rings or smell mildew after a storm. We book same-day leak scans in Montrose and River Oaks and can tarp the spot before the next rain if needed.
