Roof Replacement in Trenton, Start to Finish
Roof replacement in Trenton is a one-to-three-day job for most houses, and the decisions that matter are made before the first shingle comes off. We inspect the roof and the attic, check the decking and ventilation, and give you a written estimate that lists the materials by name. Our Old Bridge office is about 40 minutes away.
On the day, the old roof is stripped to the deck, damaged boards are replaced, and the new system goes on as a whole: underlayment, ice and water shield at the eaves and valleys, flashing, shingles and ridge ventilation.
Trenton is the capital of New Jersey and the county seat of Mercer County, on the Delaware River.
Signs It's Time to Replace, Not Repair
Three tests decide it: age, how widespread the damage is, and the condition of the decking underneath.
- Age: asphalt roofs in New Jersey typically last 20 to 30 years, less on south-facing slopes and over poorly ventilated attics.
- Spread: curling, cracking or granule loss across whole slopes, not one spot.
- Decking: soft or sagging areas, or daylight through the boards in the attic.
- Repeat leaks: several repairs in a few years usually cost more than replacing once.
We show you the photos for each, so the decision is yours to make with the evidence in front of you.
What Trenton Roofs Are Up Against
Row houses, twins and older brick buildings, many over a century old, in tightly built neighbourhoods.
Flat and low-slope roofs, parapets and old brick chimneys are typical here.
Based on the homes we see in Trenton, these are the things worth asking about on an estimate:
- Two-family homes. Ask for both sides of the roof priced together, so the whole building is on one warranty and one schedule.
- Brick chimneys. On older brick, ask whether the price includes new step and counter flashing, not just sealant.
- Parapets and walls. Most flat-roof leaks start where the roof meets a wall. Ask for the parapet flashing to be part of the scope.

Roof Replacement Pricing in Trenton: What Moves the Number
A roof replacement is priced by the square (100 square feet) and adjusted for what is specific to your house:
- Size and pitch: steeper roofs take longer and need more safety equipment.
- Layers coming off: two or three old layers take longer to strip and fill more dumpsters.
- Decking: rotted boards are replaced; the estimate states how that is charged.
- Details: chimneys, skylights, valleys and walls each need flashing.
- The shingle line you choose, and the ventilation the attic needs.
Repair and replacement are priced separately when both are reasonable, with the materials named.
