Commercial Roofing in New Jersey
Flat, TPO, and EPDM systems for businesses, warehouses, retail, and multi-family buildings across New Jersey. As a GAF GoldElite Commercial contractor — GAF's top commercial credential — Green Apple can offer NDL warranty coverage on qualifying systems.
Commercial flat roofing backed by GAF's top credential.
Green Apple Roofing installs, replaces, and repairs commercial flat and low-slope roofs across New Jersey. We hold GAF GoldElite Commercial certification — GAF's highest commercial contractor credential — which lets us offer warranty coverage, including No Dollar Limit (NDL) options, that protects your building and your budget.
Holding both Master Elite (residential) and GoldElite Commercial is rare: fewer than 1% of U.S. roofers carry both. For a building owner or property manager, that means one accountable contractor for everything from a warehouse membrane to the multi-family pitched roof next door.
We understand that a commercial roof problem is a business problem. Leaks over inventory, tenants, or equipment can't wait — so we run a 24-hour line and respond same-day to protect what's underneath while we plan the permanent fix.
