Princeton's rain, by the numbers

Princeton sees about 39.8 inches of rain most years.

May alone brings roughly 5.1 inches, more than any other month on the calendar.

A roof inspection ahead of that stretch is cheaper than a repair during it, for any Princeton homeowner watching for the first drip.

FEMA rates both hurricane risk (Very Low) and wind risk (Relatively Moderate) for the county that includes Princeton.

Either one is a common trigger for a sudden new Princeton leak rather than a slow, years-long one.

If a Princeton leak shows up right after a storm, start with flashing and shingle edges before assuming the worst.

Alphabetical by business name, nothing more. Speed and quality aren't part of the sort.

Can you find the actual source before you quote a repair, not just patch where the ceiling is wet?
Is this a contained repair, or does it point to a bigger problem with the roof?
Will you check the attic and insulation for existing water damage, not just the roof surface?
What's your timeline if it's actively raining versus once it's dry?
Do you offer a temporary tarp while a full repair is scheduled?
What's covered by a workmanship warranty on the repair itself?
