What a Teaneck roof is actually up against
The weather here is hard on roofs in a way that catches a lot of homeowners off guard. Summer in Teaneck arrives heavy and humid, and the heat that builds up under an asphalt roof bakes the shingles from below while the sun works on them from above. A poorly vented attic turns into an oven, and the trapped heat shortens the life of everything overhead. Then the storm season opens. The hard thunderstorms that build on a July afternoon push rain into any seam that is not sealed tight, and the coastal storms of autumn stack hours of steady soaking on top of real wind. A roof that aged quietly all summer is suddenly asked to shed a serious volume of water under genuine load, and the worn spots are the first to fail.
Winter is the slower test, and frequently the more punishing one. Snow settles on a roof warmed from below by the attic, melts, runs down to the cold overhang at the eave, and freezes into a ridge of ice that backs water up beneath the shingles. That same freeze-and-thaw cycle pries at every small crack and tired flashing detail, opening it a little wider with each cold snap. The leak that finally shows itself in February was often born from a brittle gap that gave way the previous summer. Knowing that pattern is half of keeping a Teaneck roof sound, and it is why we lean so hard on catching problems before the cold arrives.
