Valley leaks
Where two roof slopes meet
Gutter guards stop leaves and debris filling the gutter, which matters because an overflowing gutter pushes water back under the shingle edge and down the fascia. They are not maintenance-free — fine debris still accumulates on top and needs clearing — but they turn a twice-yearly clearing job into an annual one and prevent the blockages that cause overflow in the first place. Quality varies enormously and the cheapest mesh types clog faster than no guard at all.
Belle Terre sits on a barrier-adjacent island where three things attack a roof at once. Salt air corrodes every metal component up there — flashing, fasteners, drip edge, vent collars — so the parts meant to outlast the shingles frequently do not, and most leaks here turn out to be metal failures rather than shingle failures. Nor'easters bring sustained wind with rain driven sideways, which gets under courses that would shed any amount of vertical water. Then winter adds ice damming at the eaves, where meltwater running down a warm roof refreezes over the cold overhang and backs up beneath the shingles. Housing stock across Suffolk County runs older than the national average, with a lot of complex roof geometry, dormers and additions — and every junction is another place flashing has to work.
Belle Terre has a population of about 808, and the housing stock here sets the pattern for what fails first on a roof.
No, and anyone saying so is overselling. Fine debris and pollen still accumulate on top and in the gutter beneath. They reduce the frequency substantially; they do not eliminate it.
Badly fitted ones can. Types that wedge under the first shingle course lift it and break the seal, which creates exactly the leak path you were trying to protect. Fitting matters more than the product.
