What a Parsippany year does to the roof over your head
A roof in Parsippany lives through a wider swing of weather than people give it credit for. The summers here turn hot and heavy with humidity, and the afternoon storms that build over Morris County can drop straight-line winds and pea-size hail in the span of ten minutes before clearing as if nothing happened. Those quick, violent cells are what loosen shingles, dent metal flashing, and split aging tabs, and because the storm passes so fast a homeowner often never connects the brief downpour to the leak that shows up a month later. By the time the ceiling stains, the actual damage is old news.
Then the seasons turn. The winters bring the freeze-thaw cycle that works at every small opening a roof has, prying at nail heads and flashing seams a little more with each cold night and mild afternoon. Spring runs the rain hard and steady, which is the season that finds out whether the gutters and valleys can actually move water. Across all of it, the township's heavy tree cover keeps roofs shaded and damp, and shade plus moisture is exactly the recipe for the dark algae streaking and the soft, holding-water spots we find on so many north-facing slopes here. We inspect with the whole calendar in mind, because the roof that looks sound on a dry June morning may already be carrying three different problems waiting for three different seasons.
