45%Of Lambertville homes are attached houses. New Jersey: 10%.
52%Of Lambertville homes were built before 1940. New Jersey: 17%.
22%Of Raritan Township homes are attached houses.
40+Inches of snow a year on average in the Highlands, 40 to 50 per the State Climatologist. Fifteen of the 26 Hunterdon County towns are there.

Lambertville's median house dates to 1938, and 45 percent of its homes are attached houses, many of them in rows. On a row, each roof meets the next at a seam, and the seam is where a lot of leaks begin. Water that gets in there can show up on either side of the shared wall.

Raritan Township is newer, with a median house from 1986, but 22 percent of its homes are attached too. The same seam needs checking there, along with the flashing wherever a roof runs into a taller wall.

In the Highlands towns, from Lebanon Township to High Bridge, winter leaks often start at the eaves. Snow sits on the roof longer, melt water freezes at the cold edge, and the ice can push water back up under the shingles. The stain then turns up near an outside wall, a long way from the middle of the ceiling.

A ceiling stain tells you water got in. It does not tell you where. We go up, follow it back, and photograph the spot before we price the repair.

Before we fix it

How we trace a leak on a Hunterdon County house

Water runs along the rafters and the deck before it drips, so the stain is often a few feet from the hole. We start on the roof and in the attic and work back from there.

On Hunterdon County roofs, we check

  • On an attached house, the seam between your roof and the next one.
  • The eaves and the first rows of shingles, where Highlands ice backs water up.
  • Flashing at the chimney, which on many houses here still carries boiler exhaust.
  • Valleys and dormer walls, where two surfaces meet.
  • The rubber boots around vent pipes, which crack as they dry out.
  • The attic above the stain, for wet boards and the path the water took.

The Highlands

Alexandria to Tewksbury, 15 towns

After a snowstorm, a leak in these 15 towns is often an ice dam. Ice builds at the overhang, melt water pools behind it, and it finds a way under the shingles. We repair the spot, and then we look in the attic to see why ice keeps building on that edge.

Delaware, East Amwell, Flemington, Franklin, Frenchtown, Kingwood, Lambertville, Raritan, Readington, Stockton, West Amwell

Here the house tells us where to look. On attached houses in Lambertville and Raritan Township, we start at the seam with the house next door. On the older houses in Frenchtown, where half the homes went up before 1940, and in Stockton, we start at the chimney and wall flashing, and at any tar someone has spread over it.

If the flashing is fine and the brick above it is soaking up water, the chimney needs the work, not the roof. Chimney repair in Hunterdon County

How it works

How a roof repair works in Hunterdon County

Finding the cause comes first, and your written estimate lists what we will fix and how long it will take. All six steps are on the roof repair page.

  1. We find where the water gets in

    We get on the roof when it is safe to, check the attic under the stain, and trace the water back to where it enters. You get the photos.

  2. Written estimate

    What is wrong, what we will fix and the price, on paper. If the roof is past repairing, we tell you that and show you why.

  3. We fix the cause

    New flashing, replaced shingles or a section of new underlayment. If the deck under it is soft, you get photos and a price before we replace it.

  4. Seal, clean up and show you

    New shingles get nailed and sealed to the ones around them. We run a magnet over the lawn for nails and go over photos of the repair with you.

Do you need a permit for a roof repair in Hunterdon County?

On a detached one- or two-family house, no. New Jersey's construction code treats repairing the roof covering on a detached one- or two-family house as ordinary maintenance, so there is no permit and no notice to the town. A townhouse or other attached house usually goes through the town's construction office. Lambertville has historic districts, where the Historic Preservation Commission reviews exterior work, though in-kind roof and siding repair does not need its review. We check with your town before we start, and any permit goes on the estimate.

FAQ

Roof repair questions in Hunterdon County

Still not covered? Call 732-682-9251 and ask.

If it is in Hunterdon County, yes. We cover all 26 municipalities, from Alexandria to West Amwell. Put your ZIP code in the estimate form and we confirm it when we call you back.

We are open 24 hours, so call when you see water. If the roof is iced over or the wind is up, we stop the water for now and come back to do the real repair when it is safe. We tell you which work is temporary.

Sometimes yours, sometimes your neighbor's, and often the seam between them. Water that gets in at the seam can run down either side of the shared wall. We look at your roof and the line where it meets theirs. We do not step onto their roof without their say so, but you get photos to show them.

Ice at the edge of the roof is the usual suspect, most of all in the Highlands towns. Melt water backs up behind the ice, gets under the shingles, and stops once it thaws. We look at the eaves and the attic boards above them and send you photos.

It depends on what failed and how much roof we have to open to get at it. A cracked vent boot is a small job. Ice damage along an eave, or a seam between two attached roofs, takes more. We do not quote over the phone. The written price comes once we know where the water gets in.

On a detached one- or two-family house, roof covering repairs need no construction permit, because state code counts them as ordinary maintenance. On an attached house, like a Lambertville rowhouse or a Raritan Township townhouse, the repair goes through the town's construction office. Lambertville has historic districts, where the Historic Preservation Commission reviews exterior work, though in-kind roof and siding repair does not need its review.

Call us, but check with your association first. In most condos the roof and the siding belong to the association, and the board hires the contractor. Townhouses vary. Your association documents say who owns what.
