Roofing FAQ
Quick answers to the roofing questions Hackettstown homeowners ask most.
Frequently asked questions
What happens when I call?
You'll answer a couple of questions about the roof and where you are, then talk to a local roofer who serves your area.
Does it cost anything to use this service?
No. Calling through this site is free.
Why do I get leaks only in winter?
Usually ice dams: snow melts on a warm roof, refreezes at the cold eaves and backs water under the shingles. See ice dam roof repair.
How do I check a roofer is legitimate in New Jersey?
Home improvement contractors must be registered with the NJ Division of Consumer Affairs. Ask for the registration number and a written contract before any work starts.
How much snow does Hackettstown get?
Warren County averages roughly 30 to 40 inches a year, more than most of New Jersey. Higher ground often gets more.
Can a slate roof be repaired instead of replaced?
Often, yes. Good slate can last a century; the nails and flashing usually fail first. See slate roof repair.
Do metal roofs stop ice dams?
They shed snow well, which reduces ice dams, but snow can slide off in large sheets. Snow guards over entrances are a good idea.
Do I need a permit to replace my roof in New Jersey?
For a detached one- or two-family home, replacing the roof covering is generally ordinary maintenance with no permit needed. Replacing roof boards, structural work, new skylights, and attached or multi-family buildings are different.
When is the best time to replace a roof here?
Late spring to early fall, so shingles can seal properly and the work is done before snow. Leaking roofs shouldn't wait for the perfect season.
Should I rake snow off my roof?
Raking the lower few feet from the ground helps prevent ice dams. Never climb onto a snowy roof.
What is ice and water shield?
A self-sealing waterproof membrane installed under shingles at the eaves, valleys and around chimneys. It's standard on new roofs in snowy areas.
What should I do if a tree falls on my roof?
Get everyone out of the affected rooms, stay clear of wires, don't try to remove it yourself, and call. See storm and tree damage.
