What wears out an Englewood roof
A roof in this part of New Jersey never gets an easy stretch. Summer arrives humid and hot, and the heat that piles up in an unvented Englewood attic cooks asphalt shingles from underneath while the sun works on them from above. Then the storms roll in. The fast, hard thunderstorms that build over the ridge on a July afternoon drive rain sideways into anything that is not sealed tight, and the autumn coastal storms stack wind on top of hours of steady rain. A roof that spent the summer quietly aging is suddenly asked to shed a serious volume of water under real pressure, and the tired spots are the first to let go.
Winter is slower and more punishing. When snow settles on an Englewood roof above a warm attic, it melts, slides down to the cold overhang at the eave, and freezes into an ice dam that backs water up beneath the shingles. The same freeze-and-thaw rhythm that builds those dams goes to work on every small crack and gap, widening it a little with each cold snap. The leak that finally shows up in February was frequently born from a brittle flashing detail that gave out the previous summer. That is exactly why we push so hard for an inspection before the cold settles in, while there is still time to seal the vulnerable spots before water and ice ever reach them.
