Metal roofing lasts 40-70 years and is the longest-lasting option for most climates. Architectural asphalt shingles (the most common choice) last 25-30 years with proper ventilation. In Greenwich, NJ, factor in hail frequency, temperature swings, and snowfall load when picking your material.

Most municipalities in New Jersey require a roofing permit, though some exempt straightforward shingle replacements. Your contractor should pull and post the permit. If they suggest skipping it, that's a red flag. Unpermitted work can complicate home sales and void your homeowner's insurance if a leak occurs.

Ice dams form when heat escapes through the roof, melts snow near the ridge, and refreezes at the eaves. The root cause is usually inadequate attic insulation or ventilation, not the roof itself. A replacement is a good time to add an ice-and-water shield extending 24 inches past the interior wall line, which is the code minimum in most northern New Jersey jurisdictions.

ROI scores reflect what buyers pay for the improvement at resale relative to replacement cost. In markets like Cumberland County where home values are $282,629, a new roof is largely expected by buyers. It's a maintenance cost, not a value-add. That doesn't change whether you should replace it. A failing roof is still a priority. It just means the financial return is modest.

In 2026's high season for Cumberland County, most experienced roofing contractors are booking 4-8 weeks out. Getting three quotes now rather than waiting improves both your options and your pricing leverage. The best crews fill up first.

Homes built before 1940 often have skip sheathing (boards spaced apart) rather than solid plywood decking underneath the shingles. Modern shingles require solid decking, which means full sheathing installation as part of the project. This typically adds $1,500-$4,000 depending on roof size. Have your contractor inspect the decking type before finalizing the bid.
