Tyler’s humid subtropical climate brings hot summers and frequent rain that accelerates corrosion on metal flashing, especially around chimneys and valleys in older neighborhoods like Charnwood and the Azalea District. Homes built before the 1980s often have galvanized or copper flashing that develops pinholes where sealant has dried out, allowing water to migrate under shingles during heavy downpours. Proper repair requires removing damaged sections, installing new step flashing with correct overlap, and sealing with high-temperature butyl tape rated for our summer roof temperatures rather than standard caulk that fails quickly here.
In Smith County, building practices for homes in Hollytree and near the Tyler Municipal Rose Garden frequently include complex rooflines with multiple penetrations that collect debris and hold moisture. Flashing at wall intersections and skylights must be integrated with the underlayment so water sheds properly; shortcuts like surface patching over existing flashing commonly lead to hidden rot in the decking. Local crews inspect for ice-dam equivalents during rare winter cold snaps and ensure counter-flashing is tucked into masonry joints at least 1.5 inches to meet regional wind-driven rain standards.
Edge cases appear often in Downtown Tyler properties where additions created mismatched roof pitches, forcing custom-fabricated flashing pieces rather than off-the-shelf solutions. Using aluminum or stainless steel instead of cheaper galvanized material extends service life in our mild winters when condensation still forms under the roof deck. Homeowners should avoid painting over flashing because trapped moisture underneath causes faster deterioration than leaving the metal exposed.
Technician insight
In Tyler, the thing that catches most people out with roof flashing repair is how quickly humidity and leaf debris in the Azalea District valleys turn small pinholes into deck rot before homeowners notice anything inside. Older Charnwood homes with original galvanized flashing need the metal swapped out entirely rather than just recaulked, or the same spots fail again after the next summer heat cycle.
Valley Leak on Hollytree Home
Heavy spring rain had been entering along a closed valley on a 1970s ranch in Hollytree. We found the original galvanized flashing had corroded through at the overlap. We replaced the valley with stainless steel, integrated new underlayment, and restored the shingles so water now sheds cleanly into the gutter.
