Why Wyckoff roofs wear the way they do
Northern New Jersey gives a roof no easy season. Summer here is hot and humid, and the heat that builds in an unvented Wyckoff attic bakes asphalt shingles from below while the sun cooks them from above. Then the storms arrive. The afternoon thunderstorms that roll across Bergen County in midsummer drive rain sideways into anything not flashed tight, and the nor'easters that come later in the year stack sustained wind on top of hours of heavy rain. A roof that has been quietly aging through the warm months suddenly has to shed a serious volume of water under real wind pressure, and that is when the weak points let go.
Winter brings the slowest and most destructive force of all. When snow sits on a Wyckoff roof and the attic below is warm, the snow melts, runs to the cold eave, and refreezes into an ice dam that backs water up under the shingles. The same freeze-thaw cycling that builds ice dams also works on every small crack and gap, prying each one open a little further with every cold snap. The leak that surfaces in February was often created by a brittle flashing detail the previous August. That is why we push so hard for an inspection before the cold sets in, while there is still time to seal the vulnerable spots before water and ice ever reach them.
