What to know about roofs on Trenton's row homes

Much of Trenton is brick row homes built between the 1850s and the 1920s, usually with a pitched or mansard roof in front and a flat roof in back. Because they share walls, water often gets in where one roof meets the next. Heavy rain from Hurricanes Irene in 2011 and Ida in 2021 tends to find those joints first.

Herts Roofing & Construction in Trenton

Herts Roofing & Construction understands Trenton row homes: a pitched or mansard front, a flat roof in back, and a shared joint with the neighbor on each side. We inspect all three, because that is where these houses leak. We replace flat rear roofs, reflash mansard dormers and seal party-wall joints properly, and we handle siding, porches and decks on single-family homes across the city. Book a free inspection.

Row homes, mansards and flat backs

In Mill Hill, Chambersburg and much of downtown, you'll see brick row homes and some mansard roofs with dormers. In Cadwalader Heights and the West Trenton area there are more single-family homes with steeper pitched roofs.

1Flat back roofs

Rear roofs on row homes are often flat and patched many times. We tear off and install a real membrane system.

2Mansard fronts

Mansard roofs are steep and detailed. Dormers and the transition to the flat top need careful flashing.

3Shared walls

On attached homes, the joint with your neighbor's roof has to be sealed and flashed correctly or water finds its way in.

FAQ

Can you replace just the flat back roof on my Trenton row home?

Yes. If the front roof is in good shape, we can replace only the rear flat section. We tie the new roof into the existing roof and the neighbor's walls so the joints stay watertight.

Are you licensed and insured?

Yes. We hold NJ HIC# 13VH11388400 and carry liability and workers' comp insurance. We are happy to send certificates.

Are your estimates free?

Yes. We come out, inspect the roof, take photos and give you a written price. There is no charge and no pressure.

Do you offer financing?

Yes. Financing is available on roof replacements and larger projects. Ask about it at your estimate and we will send you the options.
