Warren County roofs

Old joints, shared seams and a snowy winter

76%Of Phillipsburg homes were built before 1960. New Jersey: 36%.
44%Of Allamuchy homes are attached houses. New Jersey: 10%.
29%Attached houses in Independence.
40+Inches of snow in an average Warren County winter, 40 to 50 by the State Climatologist.

Three Phillipsburg homes in four predate 1960. On roofs that old, the shingles in the middle of a slope often outlast the joints around them: chimney flashing, valleys, vent boots and the metal along a wall. Many have been patched before, sometimes with roofing cement smeared over the metal.

Allamuchy has 44 percent of its homes in attached houses and Independence 29 percent. Where two roofs meet, water can enter on one side and come out on the other. We look at both sides of the seam where we are allowed to, and a repair on an attached house goes through the town's construction office.

In winter the eaves are the usual suspect. Heat from the attic melts snow from below, the water runs to the cold overhang and freezes, and that ridge of ice holds the next melt against the shingles. The stain then turns up near an outside wall.

A stain tells you water got in, not where. We go up when it is safe, follow the water back to the opening, and photograph it before we put a price on the repair.

Before we fix it

Finding the leak on a Warren County roof

Water runs along rafters and boards before it drips, so the spot on the ceiling is a clue, not an answer. We start at the roof and in the attic.

On Warren County roofs, we check

  • The eaves and the lowest rows of shingles, where ice holds melt water.
  • Chimney flashing, and any roofing cement smeared over it. Many chimneys here vent an oil boiler.
  • Valleys, where two slopes drain into one line.
  • Rubber vent boots, which crack as they dry out.
  • On an attached house, the seam with the house next door.
  • The attic boards above the stain, for the path the water took.

When a roof leaks in more than one place and the shingles are worn through, another patch only buys time. If that is where yours is, we say so. Roof replacement in Warren County

Attached houses

Allamuchy, Independence, Phillipsburg

Allamuchy is 44 percent attached houses, Independence 29 and Phillipsburg 18. On a shared roof the seam between units is a joint like any other, and it leaks like one. The repair goes through the town's construction office, and if an association owns the roof, the board hires the contractor.

Detached houses

Blairstown, Frelinghuysen, Hope and the other townships

In Frelinghuysen 99 percent of homes are detached houses, and Hope and Blairstown are close behind. Most of them heat with oil, so the brick chimney through the roof is a common leak point, and after a snowfall the eaves join the list. A roof repair on one of these houses needs no construction permit.

If the flashing is fine but water is coming through the brick above it, the repair belongs to the chimney. Chimney repair in Warren County

How it works

How a roof repair works in Warren 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 Warren 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. Belvidere's historic district has its own review by the Historic Preservation Advisory Commission, but maintenance of existing roof material and in-kind siding replacement are exempt. We check with your town before we start, and any permit goes on the estimate.

FAQ

Roof repair questions in Warren County

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

If it is in Warren County, yes. We cover all 22 municipalities, from Allamuchy to White. Put your ZIP code in the estimate form and we confirm it when we call you back.

Yes, call when you see water. We are open 24 hours. In a storm the first job is a temporary fix that stops the water and protects the rooms below. The lasting repair waits until the roof is safe to work on, and we tell you which is which.

Usually ice at the eaves. Melt water from higher up freezes at the cold edge, then the next melt backs up behind it and finds a way under the shingles. We look at the eaves and the attic above them and show you in photos.

Not a construction permit on a detached one- or two-family house. State code counts roof covering repairs there as ordinary maintenance. Attached houses, common in Allamuchy and Independence, go through the town's construction office. In Belvidere's historic district, maintenance of existing roof material is exempt from the Historic Preservation Advisory Commission review.

It comes down to what failed and how much roof has to be opened to reach it. A cracked vent boot is a short job. Flashing around an old chimney, or ice damage along a whole eave, is more. We do not quote over the phone. Once we have found the opening, you get the price in writing.

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.
