MERCER COUNTY ROOFS
Trenton’s older neighborhoods are full of attached, flat-roofed homes. Those roofs wear differently from a pitched suburban roof.
Attached homes share a roof line. A leak next door or a poorly sealed seam between roofs can send water into your home.
Water that sits for days after rain breaks down seams and flashing. Fixing low spots and drains matters as much as the patch.
Melting snow refreezes at cold edges and gutters, backing water under shingles. Repeated freezing also cracks old masonry.

MERCER COUNTY ROOFING FAQS
Yes, by appointment. We’re based in Clifton, in North Jersey, and schedule Mercer County jobs in advance, from Trenton to Princeton. Send us your town and ZIP code and we’ll confirm a date for your free inspection.
Each owner is usually responsible for their own section, but water doesn’t follow property lines. We inspect your section and the seams where it meets next door, and explain where the water is coming from so you can talk to your neighbor.
We install torch-down modified bitumen on flat and low-slope roofs. The seams are heat-welded, which holds up well against standing water. We also correct low spots and clear drains so water leaves the roof.
Often it’s an ice dam. Snow melts over a warm attic, refreezes at the cold edge and backs water under the shingles. Better insulation and ventilation help, and a new roof can include a waterproof underlayment along the eaves.
It depends on whether the roof is flat or pitched, its size, how many layers come off, decking repairs and the material. After a free inspection, you get a written estimate that lists the work so nothing is a surprise.
Yes. We repair chimneys and masonry, including loose brick, worn mortar and the flashing where the chimney meets the roof. On older homes, fixing both at once often stops leaks that keep coming back.
Yes. We install and repair vinyl siding and cedar shake. On older homes we check the trim and sheathing behind the siding for rot, and can plan siding with a roof job so the flashing ties in cleanly.
Move belongings, catch the water and keep people away from any bulging ceiling. Then call (201) 565-6664. We answer 24/7 and will confirm when a crew can reach your Mercer County home to secure the roof.
