| Typical homes | Paulus Hook, Van Vorst Park, Hamilton Park and Harsimus Cove are full of 19th-century row houses with flat roofs, cornices and parapet walls. Uptown and on the West Side, the typical house is a frame two-family with a gable roof and aluminum or vinyl siding. Many buildings share walls, so a leak can start on the building next door. |

Roofing Jersey City's brownstones and two-families
Downtown Jersey City is mostly 1800s brownstones and row houses with flat roofs behind a parapet wall. Up in the Heights and on the West Side you'll find frame two-families with pitched roofs and siding. Both take a beating from storms off the water, as Hurricanes Sandy and Ida showed. On a flat roof, leaks usually start at the parapet, drains and flashing. On a two-family, they start at shared walls and porch roofs.
Herts Roofing & Construction works on both kinds of Jersey City home: brownstone flat roofs downtown and frame two-families in the Heights and on the West Side. On a brownstone we check the parapets, coping, drains and bulkhead flashing, not just the membrane. On a two-family we look at the shared walls, porch roofs and old siding. Knowing how each kind of house was built is why our estimates hold up once the work starts. Book a free inspection.
Jersey City housing, block by block
Ponding water on flat roofs
Low spots and clogged drains leave standing water that breaks down the roof membrane. We fix the slope and drainage, not just the surface.
Parapet and coping leaks
Cracked mortar and loose coping stones let water run down inside the wall. It often shows up as a stain two floors down.
Wind off the water
Edges and ridges take the most wind. We use proper edge metal and nailing patterns so the roof stays put.
How old is your roof?
Type a year to see where your roof likely stands. Most asphalt shingle roofs last about 20 to 30 years.

Questions from Jersey City homeowners
Can you replace a flat roof on a Jersey City brownstone?
Yes. We remove the old roof down to the deck, repair any rotted boards, fix drainage and install a new membrane system. We also check parapets, coping and flashing at chimneys and bulkheads, since those are where most brownstone leaks start.
Do you go over the old roof or tear it off?
We tear off every layer down to the decking. That is the only way to find rotted wood and give you a roof that lasts.
What shingles do you install?
We are an Owens Corning Preferred Contractor, so most of our roofs are Owens Corning architectural shingles. Premium lines are available too.
What warranty comes with a new roof?
We give a 15-year workmanship warranty on roof replacements, and Owens Corning systems carry manufacturer coverage on top of that.
