Williamstown, NJ
Why Williamstown Roofs Take a Beating
Williamstown mixes older homes near the centre of Monroe Township with newer developments on open lots, where roofs take the full force of the wind. After a storm, lifted and creased shingles are what we find most often here, and they are easy to miss from the ground.
After a storm, be wary of crews knocking on doors along your street. Ask for the company’s NJ registration number and look it up yourself (our two-minute guide), and don’t sign anything that lets a contractor negotiate your insurance claim for you. Our storm damage guide explains how claims should work.

FAQs
Frequently Asked Questions
Straight answers on cost, permits, storm claims and choosing a roofer in New Jersey.
Still have a question?
Talk to M&J’s office in Blackwood. Monday to Friday, 8am to 4:30pm.
How much does a roof replacement cost in South Jersey?
Most residential replacements run roughly $8,000 to $18,000, driven by roof size, pitch and material. Asphalt shingle sits at the lower end; metal costs more upfront and lasts decades longer. Our South Jersey roofing cost guide breaks the numbers down.
Do I need a permit to replace my roof in New Jersey?
Usually not. Since 2018, New Jersey has not required a construction permit for like-for-like roof replacement on one- and two-family homes. Structural changes, commercial buildings and multi-family properties still do.
Someone knocked on my door after the storm. Should I sign?
Not on the spot. Storm-chasing crews follow weather events, take a deposit, and are frequently gone before the warranty matters. Our guide on how to choose a roofing contractor covers what to check first.
How long does the work take?
Most repairs are done in a single visit. A typical residential replacement is a one to two day job once materials arrive.
Can you help with a storm damage insurance claim?
Yes. We document wind and hail damage with dated photographs and a written report for your adjuster, and can meet them on site. See storm damage and insurance claims.
How do I verify a contractor's license in New Jersey?
Search the name or license number on the NJ Division of Consumer Affairs verification site. Ours is NJ HIC #13VH12363400.
