Longview's older housing stock in neighborhoods such as Downtown Longview and Judson often features original flashing that has thinned after years of hot humid summers and repeated thunderstorm cycles. Thunderstorms drive water under lifted edges at chimneys and pipe boots, especially on homes built before modern step flashing standards became common in Gregg County. We inspect the full perimeter, replace corroded sections with compatible metals, and seal transitions to match the existing roof slope and material.
Homes near Eastman Road and in North Longview sit on flatter lots where poor drainage concentrates runoff at wall intersections. Flashing here must extend higher and tie into siding properly or leaks reappear within one season. Our crews carry both aluminum and copper stock to match the original installation and avoid galvanic corrosion with nearby fasteners or gutters.
Spring Hill and Pine Tree properties frequently need valley flashing work after wind-driven rain forces water under the existing metal. We remove the old flashing, check for deck rot, and install new pre-formed valleys with extended kickouts that direct water away from exterior walls. This prevents the interior staining that appears weeks after a storm passes.
Nearby cities such as Kilgore and Marshall share the same weather patterns, so we see identical flashing failures on ranch-style homes with low-pitch roofs. Proper counter-flashing at masonry chimneys and correct pipe boot heights remain the most common omissions that allow water entry during mild winters when condensation adds to the load.
Technician insight
In Longview the thing that catches most people out with roof flashing repair is how quickly thunderstorms push water under the old lead or aluminum on homes in Judson and Spring Hill where the original flashing has been in place since the houses were built decades ago. The humidity keeps the wood deck damp longer so rot spreads farther than the visible stain suggests.
North Longview ranch home valley leak
Homeowner noticed ceiling stains after spring storms. We found lifted valley flashing on the low-pitch roof where runoff from the main section met the garage addition. We replaced the valley metal, added a longer kickout, and sealed the new seams. No further leaks appeared during the next thunderstorm season.
