Flat Roof Repair in North New Jersey

Black rubber sheets with glued seams are EPDM. White or light-gray plastic-like sheets with welded seams are TPO or PVC. Granulated rolls that look like a thick shingle surface are modified bitumen. A surface of gravel over tar is a built-up roof. It matters because each one requires compatible repair materials, and we confirm it before we start.

Either it cannot get to the drain or the drain cannot take it. Blocked drains and scuppers are the common cause and the easy fix. Sagging insulation, a deflected deck, or a roof that was never sloped properly create low spots that need crickets or tapered insulation to correct. We find out which before recommending anything.

Yes, within limits. Heat-welded membranes like TPO can be repaired in cold weather. Adhesives for EPDM and some modified bitumen products need minimum temperatures to cure, so certain repairs are scheduled for a milder day. An active leak gets addressed regardless, with a permanent repair to follow if the material requires it.

It depends on the membrane type, the size and number of areas being repaired, whether wet insulation has to be removed, how much flashing is involved, and access to the roof. A single seam or drain repair is a small job; rebuilding parapet flashing around an entire roof is not. We assess the roof and give you a free written estimate.

Coatings have a place on a roof that is structurally sound and dry but weathered. They do not fix open seams, wet insulation, or failed flashing; those have to be repaired first. A coating over problems hides them for a season. We will tell you honestly whether your roof is a candidate.

Twice a year is a good habit: once in late fall after leaves have dropped, and once in spring after winter. Clear the drains, look for standing water, check seams and flashing, and walk it after any contractor has been up there. Catching a split seam early is a patch; finding it a year later is wet insulation.
