Trenton roofs see big swings from humid summers to freezing winters. Shingles expand and contract until nails pop or seals crack around vents. We check every seam on asphalt and modified bitumen roofs because those are the usual failure points in East Trenton homes built before 1980.
Cheap crews often slap tar over a leak without tracing where water actually enters. That leaves rot under the deck in places like Mill Hill. We pull back shingles, inspect the felt, and replace any soft plywood so the fix lasts through the next freeze cycle.
Mercer County requires a permit for any roof work over 100 square feet. We pull the paperwork and make sure the patch meets current wind and snow load rules. Skipping this step risks fines when you sell the house later.
Call us 24/7 for emergency roof leak repair. We show up with tarps and materials to stop water the same day in South Trenton or Cadwalader Park neighborhoods.

How it works
- 1
Inspect The Roof
We walk the whole roof and attic, mark every suspect spot, and check inside for water stains. Takes 30 to 60 minutes.
- 2
Trace The Leak Path
Remove shingles or membrane around the wet area to follow water back to the entry point. Usually 1 hour.
- 3
Make The Repair
Install new flashing, sealant, or matching shingles, then test with a hose. Most patches finish in 2 to 4 hours.
- 4
Clean Up And Check
Remove debris, check the attic again for dryness, and give you a written note on what was fixed.
Pricing
Most leak repairs fall between 350 and 1200 dollars. Bigger access issues or rotted decking push the high end.
