LEAK REPAIRS WE DO
Most leaks we see in Union County come from three places. Here is how we handle each one.

On torch-down flat roofs we repair split seams, blisters and worn areas around drains and scuppers, and deal with the low spots where water ponds after rain.

Cape dormers and walls meeting the roof rely on step flashing. We open the area, replace worn flashing and reseal it so water stops running behind the siding.

Older brick chimneys leak at the flashing, the crown or through the mortar. We repair the flashing and show you any masonry work the chimney needs as well.

WHERE TO LOOK
Leaks in older city and suburban homes often show up away from the source. These are the places to check.
In a two-family home, the upstairs unit usually sees a roof leak first, often near walls or the chimney.
Blisters, cracks or soft spots on a flat roof are where water gets under the membrane.
Peeling paint or damp plaster at a dormer or knee wall can mean the flashing above has failed.

LEAK REPAIR FAQS
We offer same-day service and answer the phone 24/7. If water is coming in now, we secure the roof first, and the permanent repair follows as soon as the weather and the materials allow.
Common causes are split seams, blisters, worn flashing at walls and water ponding in low spots. Patching one spot won’t help if water keeps sitting on the roof. We find the cause and explain how to deal with the drainage too.
Ask them to move belongings, catch the water and stay clear of any bulging ceiling. Then call us. We’ll inspect the roof, secure it if needed and send you, as the owner, photos and a written estimate.
Usually. Cape dormers leak where the side walls meet the roof, at the valleys or along the dormer’s own roof edge. We find which one it is, replace the flashing and shingles involved and seal it properly.
It depends on the roof type, the source and how much is damaged. A flat roof seam, a dormer wall and a chimney all need different work. We inspect for free and give you a written estimate before starting.
It can be either. Water can enter through worn flashing, a cracked crown or porous brick. We check all three and explain which one is the cause. We repair chimneys and masonry too, so you only need one contractor.
Some can. Torch-down repairs need a dry surface and suitable conditions. If a lasting repair isn’t possible on the day, we’ll secure the area to stop the water and come back to finish when conditions allow.
It depends on the cause. Sudden damage, like wind lifting shingles or tearing a flat roof, is often covered; slow wear usually isn’t. Check your policy. We’ll give you photos and notes to pass on to your insurer.
