LEAK REPAIR SERVICES

How we stop leaks in Warren County

Leaks on older and rural homes come from a few usual suspects. We check each one before deciding on a repair.

  • Shingle and ridge repair on an asphalt roof

    Porch and low-slope roofs

    Low porch roofs on older homes often leak where they meet the house wall. We repair the roofing surface and replace the wall flashing so water runs off, not in.

  • Crew on scaffolding at a stone colonial home

    Metal roof leaks

    On older metal roofs, leaks come from loose fasteners, rusted seams and failed flashing. We repair the problem areas and tell you how the rest of the roof is holding up.

  • Cape Cod house during a roof tear-off

    Wind-driven rain leaks

    Homes on hilltops and open fields take rain sideways. We find lifted shingles, gaps at the rakes and ridge and loose flashing, then reseal and secure them.

WHAT TO WATCH FOR

Clues that your roof is leaking.

Some leaks take a while to show. Keep an eye out for these, especially after windy storms.

  • Stains on the porch ceiling

    Water marks on a porch ceiling or where it meets the house usually point to failed wall flashing.

  • Leaks on one side only

    If leaks appear only when wind drives rain against one side of the house, look at that side’s edges and flashing.

  • Rusty nails in the attic

    Rust-stained nails or dark rings on the attic boards suggest slow, repeated moisture from above.

Don’t wait for the stain to spread. Call (201) 565-6664 for a free inspection, or any time if water is coming in.

Yes. We repair leaks across Warren County, in town and on rural properties. ADZ Roofing is based in Clifton, so we confirm scheduling by ZIP code. If water is coming in, call any time; we answer 24/7.

That joint depends on flashing tucked under the siding and over the porch roof. On older homes it’s often rusted, missing or covered with sealant that has cracked. We replace the flashing and repair the porch roof surface.

Often, yes. We tighten or replace loose fasteners, seal or repair seams and replace failed flashing. If the panels are rusted through in many places, we’ll explain when a new standing-seam roof makes more sense.

Exposed homes take most of their weather from one direction. Wind lifts shingles at the rakes and ridge and pushes rain under flashing on that side. We inspect the weather side closely and secure whatever is loose.

The cause, the roof material and how far the water has spread. Replacing a vent boot is a smaller job than rebuilding porch flashing or repairing a metal seam. You get a free inspection and a written estimate before work.

Yes. Water from failed flashing can run down inside a wall before it shows, often at a window or baseboard below. If you see stains low on a wall under a roof joint, we’ll check the flashing above.

We’d advise against it. Tar can trap water, hides the real problem and often has to be removed before a proper repair. If you need a stopgap, call us and we can secure the area safely.

Yes. We photograph the damage and its source and write down what we found and repaired. You can share these with your insurer. Coverage depends on your policy and on whether the damage was sudden.
