Roofing for Trenton homes
Trenton covers about 7.6 square miles of Mercer County and has roughly 35,870 homes and apartments. That’s a mature housing stock, with more than 60% of them built before 1960. A majority of homes are rentals, so a lot of our Trenton work is for landlords and property managers who need roofs fixed quickly and done right.
Housing figures: U.S. Census Bureau, 2019–2023 American Community Survey 5-year estimates.
Spring and fall are ideal
Spring, after winter’s freeze-thaw damage shows up, and fall, before leaves and snow arrive, are the best times to book roof work in Trenton. Shingles also seal best in mild weather.

What Trenton homeowners should know
Based on the age and type of homes in Trenton and the weather it gets.
Post-war homes on their second or third roof
The typical home in Trenton was built in the 1950s, and about 65% of homes predate 1960. Capes, ranches, and split-levels from this era have usually been re-roofed at least once, sometimes right over the original layer. Before a replacement, it’s worth confirming how many layers are up there and checking the decking once they come off.
A large stock of century-old buildings
Newer construction has pulled the median down, but about 41% of homes in Trenton were built in 1939 or earlier. Those older buildings often have board decking, several layers of old roofing, and decades of patches, so tear-offs and decking repairs are a regular part of roofing here.
Multi-family and rental buildings
About 64% of homes in Trenton are renter-occupied, so there are plenty of two-family homes, apartment buildings, and mixed-use blocks. Many have flat or low-slope roofs, where drains, seams, and parapet walls need regular attention. We work with owners, landlords, and property managers on repairs and replacements.
Trees, storms, and freeze-thaw
Mature trees, nor’easters, and winter freeze-thaw cycles are what wear roofs down in Trenton. Falling limbs damage shingles, leaves clog gutters and valleys, and water that freezes in small gaps opens them wider each winter.

Roof repair in Trenton
Most roof leaks in Trenton start small: a cracked pipe boot, a lifted shingle, or flashing that has pulled away from a wall. We trace the water back to where it actually gets in, which isn’t always right above the stain, and fix the cause instead of smearing sealant over the symptom. Typical repairs include replacing damaged or missing shingles, resealing or replacing flashing, swapping out worn pipe boots and vents, and cutting out soft decking so the repair sits on solid wood.
Roof replacement in Trenton
New roofs start at $6,500, and every Trenton replacement we do includes the layers you don’t see: tear-off of the old roofing, decking repairs, underlayment, new drip edge and flashing, and ridge ventilation, topped with the shingle color and style you choose. Many single-family roofs are finished in one to a few days, and we clean up before we leave.
Storm damage & 24/7 emergency roofing
When a roof emergency hits in Trenton, our first goal is stopping the water. We tarp or temporarily repair the damaged area, then come back to make a proper repair. Our written estimate describes the damage and the work, which helps if you’re filing an insurance claim. Call (201) 773-6635 any time, day or night.
Flat roof repair & replacement
Plenty of Trenton buildings have flat or low-slope roofs on additions, porches, garages, and multi-family homes. We repair and replace TPO, PVC, torch-down, and roll roofing. Most flat-roof leaks start at seams, roof drains, and the edges where the roof meets a wall, so those get special attention, and we make sure water drains instead of ponding.
