If your commercial roof is leaking, ponding water, or the seams are starting to bubble, you’re not the only owner in Trenton dealing with it. Flat and low-slope roofs around the city see a lot of stress from storms, traffic on the roof, and older patch jobs. Not gonna lie, one small roof leak can turn into damaged inventory pretty fast.
Keystone Roofing, Siding & Windows provides full commercial roofing services for Trenton businesses. From small storefronts downtown to warehouses off Route 1 and mixed-use buildings near the State House, we repair, restore, and replace commercial roofs with systems built for New Jersey weather.
Many commercial roofs in Trenton are older EPDM or built-up systems that are past their best years. Add in rooftop HVAC units, skylights, and drains, and there are a lot of places for water to sneak in.
