Low Pitch Roof Repair for Leaking Extensions, Porches and Garages
Low pitch roof repair gets your leaking low-slope roof dry again, and Flat Roofers NY does it across Queens from Elmhurst.
- Leaks and open seams, patched and resealed
- Flashing at walls and edges
- Drains and scuppers, cleared so water runs off
Slow runoff: why a shallow pitch leaks
Rain drains slowly off a low slope, so it pools after every storm. Wind pushes that water under laps and seams. Standing water soaks into worn wall flashing.
We open the suspect seams and check every flashing run before we patch. Water still sitting two days after rain means the drainage needs fixing, not only the leak.
Warning signs
- Ceiling stains in the room below
- Blistering
- Cracked membrane
- Seams lifting at the edges
- Standing water after rain
Is the right covering on your pitch?
Plenty of low-slope leaks come from a covering never meant for that pitch, because pitch decides which roofing material holds.
| Covering | Lowest pitch | How it fails when too flat | Our repair |
|---|---|---|---|
| Asphalt shingles | 2:12 | Water backs up under the tabs | Flashing repair or membrane recover |
| Rolled roofing | 1:12 | Laps open, nails rust | Patch and reseal |
| Modified bitumen | 1/4:12 | Split seams, blistering | Patch and reseal |
| EPDM | 1/4:12 | Taped seams lift | Seam and flashing repair |
| TPO Suits the flattest roofs |
1/4:12 | Welds crack at walls and drains | Re-weld, then coating |
Shingles or rolled roofing leaking somewhere new each season? Repairs stop paying off, and we'll quote a membrane made for the slope.
Extensions, porches, garages, dormers: where each low roof gives out
You'll find them on attached rowhouses, two-family houses, multi-family buildings and mixed-use storefronts.
-
Rear extension
Weak pointFails where the roof meets the house wall.
Our fixWe reflash that joint, the usual cause of a leak over the kitchen at the back.
-
Porch roof
Weak pointThe edge wears and runoff spills onto the steps.
Our fixNew drip edge, sealed edge strip.
-
Garage
Weak pointWorn rolled roofing and a blocked scupper.
Our fixWe clear the scupper, then patch or recover.
-
Dormer
Weak pointSide flashing lets go and the shallow face holds water.
Our fixBoth sides get reflashed, the face resealed.
Yes, if the membrane around it is sound. Cracks across the whole surface call for a membrane recover instead.
Only once the leak is repaired. Coating goes on sound, dry membrane. Over wet layers it traps the water.
Yes, on every job. Clogged drains often start the leak.
Seam, patch and flashing work usually wraps up in one visit. If water is coming in right now, we stop it first.
