LEAK REPAIR, STEP BY STEP
We don’t guess, and we don’t just smear on sealant. Each repair follows the same steps, whatever kind of roof you have.

We inspect from inside and out, then show you photos of the entry point, the damage around it and what we recommend, so you see the problem for yourself.

On pitched roofs we replace damaged shingles, reseal pipe boots and rebuild chimney flashing, a common weak spot on older Clifton and Hawthorne homes.

On torch-down and other flat roofs, we cut out blistered or split areas, torch new modified bitumen over them and clear the drains that let water pond.

SIGNS OF A ROOF LEAK
Older homes and multi-family buildings tend to leak in predictable places. Here’s where to look first.
In two- and three-family homes, the top unit sees a leak first. A tenant’s report of a stain is worth checking quickly.
Water that sits on a flat porch or rear roof for days after rain wears the surface and finds every seam.
Rubber collars around plumbing vents crack with age. The leak often shows as a small stain near a bathroom ceiling.
Leak in a rental unit? Call (201) 565-6664. We answer 24/7, coordinate access with your tenant and send you photos of the repair.

SIMPLE FROM START TO FINISH
We inspect your roof and explain what we find. Your estimate outlines the recommended work, materials and next steps, with time to ask questions before you decide.
After you approve the plan, we agree on a schedule and explain how to prepare your home. The team completes the repair or installation and keeps you informed about any changes.
We review the finished work and clean up the work area. A final walkthrough lets you ask questions and discuss the care and warranty information that applies to your roof.

Some leaks are a one-time fix. Others point to a bigger job. Here’s what we offer when the inspection says more is needed.

If patches keep failing, a full tear-off and new roof can be the better value over time than repeated repairs.

ROOF LEAK FAQS
It depends on the roof type, where the leak is and how much has gotten wet underneath. A cracked pipe boot is a small job; a soaked deck is not. We inspect for free and give you a written price first.
Yes. We can arrange access with your tenant, inspect the roof and send you photos and a written estimate, so you don’t have to take time off to be there. That works well for two- and three-family owners.
Many flat roof leaks can be patched, especially at a single seam, drain or edge. If the surface is blistered and ponding across most of the roof, a new torch-down roof is the better investment. We’ll show you which applies.
Wind-driven rain gets under lifted shingles, loose flashing and gaps at the roof edge that normal rain never reaches. Nor’easters are the usual test. We look for those weak spots and secure them.
Sealant has its place, but used alone it rarely lasts through North Jersey freeze and thaw. We replace the damaged flashing or shingles and use sealant only where the manufacturer calls for it.
Yes. Chimney flashing is a common leak point on Clifton and Hawthorne homes. We replace step and counter flashing and, since we also do masonry, repair loose mortar or a cracked crown at the same visit.
We offer same-day service and answer the phone 24/7. If water is coming in, we secure the roof first so the damage stops, then book the permanent repair for the next safe stretch of weather.
Yes. The warranty details are written into your estimate before work begins, so you know what’s covered. ADZ Roofing is registered in New Jersey as HIC #13VH12840300 and carries liability insurance.
