Quick answers for Middlesex County homeowners.

Yes. Keystone offers 24/7 emergency service, and same-day appointments are available for roofing, siding and windows. In most situations, we can also help you with your insurance claim.

Most roof replacements take just 1 day. We always do a full tear-off and never install a new roof over your old one. Vinyl siding takes about 4 to 7 days, and a combined siding and windows project about 7 to 10 days.

Yes. Keystone repairs siding, and a repair is often enough when only a few pieces are damaged. When damage is widespread, keeps coming back or has reached the wall underneath, we’ll recommend replacement and explain why.

On one- and two-family homes in New Jersey, replacing your roof, siding or windows generally doesn't need a permit. Installing any amount of polypropylene siding (like CertainTeed Cedar Impressions®) does, and so does making a window opening bigger, moving it or cutting a new one.

As a GAF Master Elite contractor, Keystone can offer GAF’s Silver Pledge and Golden Pledge warranties on new roofs. We also give our own 5-year labor warranty on siding and lifetime labor warranty on windows, and we offer financing through multiple lenders.
