Roof repair in Middlesex County, NJ

A leak in a Carteret two-family can drip into the wrong apartment. A leak in a Monroe Township townhouse can start on the roof next door. Either way, we find where the water gets in before we touch anything.

In Perth Amboy, Dunellen and Carteret, about one home in five is a two-family house. Water that gets in above the top unit can follow a wall cavity down and show up in the first floor kitchen. The tenant often sees it before the owner does.

In Monroe Township about one home in four is attached, and in South Brunswick about one in five. On a row of townhouses, the weak spots are where two roofs meet, at a party wall or a change in height. A stain in your unit can come from a gap on the roof beside yours.

Middlesex sits in the middle of the Central Zone, where winter storms often turn from rain to snow and back. Slush packed into a valley or a full gutter freezes overnight and can push water under the bottom row of shingles. Summer is hard on the roof too: in full sun a dark roof runs far hotter than the air, and old vent boots crack.

The stain is where we start, not where we fix. You see photos of the source before any repair.

Tracing the water

How we find a leak on a Middlesex County roof

Water runs along rafters and inside walls before it drips. We go on the roof and into the attic, then follow it back to the place it gets in.

Where we look first

  • Flashing at the chimney, and any tar from earlier patches on older northern houses.
  • The joint between your roof and the next one on a townhouse row.
  • Valleys and eaves, where slush from a mixed storm freezes.
  • Rubber boots on plumbing vents, which split after enough summers.
  • Attic wood above the stain, and the trail the water left.
  • Both units of a two-family house, with your tenant's okay.

Where a leak shows up depends on the house

Two-family houses

One roof over two apartments. Water can skip the top unit and appear downstairs. We walk through both units with the tenant in agreement, find the entry on the roof and repair it there. On these older roofs it is often the chimney flashing or a valley.

Townhouse rows

Attached roofs share edges. A leak at the wall between two units may start on the roof next door, so we check both sides of the joint. Repair on an attached house usually goes through the town construction office, and in many developments the association decides who fixes the roof.

How it works

How a roof repair works in Middlesex 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 Middlesex 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. Cranbury has historic districts, where exterior work needs a certificate of approval from the Historic Preservation Commission. An in-kind replacement counts as ordinary maintenance there, but the town still wants the details first. We check with your town before we start, and any permit goes on the estimate.

FAQ

Roof repair questions in Middlesex County

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

If it is in Middlesex County, yes. We cover all 25 municipalities, from Carteret to Woodbridge. Put your ZIP code in the estimate form and we confirm it when we call you back.

Call us. We are open 24 hours. In freezing weather the first goal is to stop the water and protect the rooms under it. The lasting repair may need a warmer, dry day, and we tell you which part is temporary.

On an attached row, water can come in at the joint with the next unit and travel sideways. We check your roof and the edge it shares with your neighbor's. If the source is on their side, we show you the photos.

It depends on what let the water in and how much roof around it we need to open. A split vent boot is a small job. Rebuilding chimney flashing under old tar takes more. We do not quote over the phone. You get a written price once the source is found.

On a detached one- or two-family house, no construction permit. State code counts repairs to the roof covering as ordinary maintenance. Townhouses and other attached houses usually go through the town's construction office, so we call your town before we start.

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.
