Valley leaks
Where two roof slopes meet
TPO is a single-ply membrane common on flat and low-slope roofs, heat-welded at the seams. It fails at those welds, at penetrations and curbs, and through punctures from foot traffic or debris. Repair is a welding job rather than a patching one — adhesive patches on TPO are a temporary measure at best, because the material does not bond reliably to anything other than itself under heat.
West Point sits in Georgia's hail belt, where the spring storm line coming across the state tends to organise. Hail is the dominant roof killer here and it works slowly: the stone bruises the asphalt mat under the granule surface without breaking through, so the roof keeps water out for another season or two and then starts leaking from spots that were damaged years earlier. Add the summer heat load — Harris County roofs run extremely hot, which ages the shingle and dries out the sealant around every penetration — and the failures cluster around pipe boots, flashing and anything with a rubber component.
West Point has a population of about 3,719, and the housing stock here sets the pattern for what fails first on a roof.
As an emergency measure only. The material is designed to be heat-welded to itself, and adhesive patches lift at the edges with temperature cycling. A welded repair is the actual fix.
Typically fifteen to twenty-five years depending on thickness and exposure. Seams and detailing fail well before the field of the membrane does, which is why most TPO work is repair rather than replacement.
