Flat sections over porches, garages and additions use a membrane (EPDM, TPO or modified bitumen), priced per square foot. See flat roofing.
Chimney work at the same time
Most North Jersey homes we re-roof have at least one brick chimney. Doing it while the roof is open saves a second setup.

Questions homeowners ask us
What's the average cost of a new roof in New Jersey?
Bigger, steeper or more complicated roofs cost more.
Why do roofing quotes vary so much?
Mostly scope: some quotes leave out decking, flashing or ice & water shield, or plan to go over the old roof. Compare line by line.
Is it cheaper to roof over the old shingles?
Up front, a little. But it hides rotten decking, adds weight and usually shortens the new roof's life. We tear off.
How long does a new roof last in NJ?
Architectural asphalt shingles commonly last 20–30 years here, less on shaded or poorly ventilated roofs.
When is the cheapest time to replace a roof?
Late fall and early spring can be easier to schedule. Prices change more with material costs than with season.
Do I pay everything up front?
No. The payment schedule is in your written contract.
Can I get an exact price without a visit?
A rough range from photos, yes. An exact written price needs us on the roof and in the attic.
