Valley leaks
Where two roof slopes meet
A roof certification is a written statement of condition and estimated remaining life, usually required by an insurer or requested during a property sale. It is not the same as an inspection report — it is a shorter document making a specific assertion about how long the roof has left, which means it carries more weight and is correspondingly harder to obtain on a roof in doubtful condition.
Lynbrook 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 Nassau 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.
Lynbrook has a population of about 20,438, and the housing stock here sets the pattern for what fails first on a roof.
An inspection tells you the condition. A certification asserts a remaining life in years, which is what insurers and buyers actually ask for. It is a stronger statement and some roofs cannot be certified without remedial work first.
You get a list of what needs doing to meet it. That is often a small amount of specific work rather than replacement, and having it itemised is useful regardless of whether you proceed.
