Roofing Contractor Frenchtown, NJ
Roof Repair and Replacement for Homes in the Delaware River Valley
Frenchtown sits in a river valley, and that geography decides what fails on your roof. Nor’easters push up the Delaware corridor, shaded slopes hold snow long enough to form ice dams, and steep pitches put valleys and flashing under the most stress. William Penn Roofing & Exteriors has worked as a licensed roofing contractor in Frenchtown and across Hunterdon County since 2008, handling inspections, repairs, and full replacements.
Not sure if you need a repair or a replacement? We photograph what we find and give you both options in writing, same as on the river-town homes we handle downstream in Stockton and Lambertville.

Complete Residential Roofing Solutions in Frenchtown
Roofs here rarely fail in one place. Our residential roofing services cover everything from a single leaking valley to a full system replacement, with photo documentation and written options at every stage.
Roof Inspection & Leak Diagnosis
Flashing, attic ventilation, and shingle condition explain most ceiling stains on steep-pitched roofs. You get a written report with photos and next steps.
Roof Repair
Leak repairs, shingle replacement, pipe boots, and chimney flashing, with the source corrected rather than covered. Ice dam damage is common on shaded river-facing slopes, and patching the shingle without fixing the ventilation behind it just moves the leak.
Roof Replacement & New Roof Installation
We tear off to the deck and inspect it. Many homes here have plank sheathing rather than plywood, and soft boards get replaced before anything new goes down. Ventilation and ice and water shield are included, not upsold.
Storm Damage Repair & Emergency Tarping
We tarp first to stop interior damage, then complete permanent storm damage repair once conditions allow. Dated photos and a written report go straight to your insurance carrier.
How We Run a Roof Replacement in Frenchtown
What You Are Seeing, and What It Usually Means
- A stain on a ceiling or an exterior wall. More often an ice dam backing water up under the shingles than a hole in the roof. Usually a ventilation correction plus targeted repair, not a replacement.
- Granules collecting in the gutters. The shingle is shedding its wear layer. On its own that is a budgeting signal rather than an emergency.
- Shingles missing or curled after a nor’easter. Repairable when the rest of the field is sound. If the same slope keeps losing shingles, the fasteners or the deck underneath are the real problem.
- A visible dip between rafters. Moisture has reached the plank sheathing. This is replacement territory and it gets more expensive every season it waits.
- Daylight in the attic or damp insulation. Water is actively getting in. Worth an inspection this week, not next season.
Transparent Pricing Guidance for Frenchtown Projects
Roof size, pitch, layers to tear off, decking condition, ventilation upgrades, flashing details, and Hunterdon County disposal all move the final number. Steep pitches and matching an existing slate or cedar roof sit at the top of the range.
Commercial and Low-Slope Roofing Expertise for Local Businesses
Bridge Street storefronts mostly run flat or low-slope, which fails differently than a pitched residential roof. We handle commercial roofing on those systems throughout the borough and the surrounding townships.
Commercial Roof Repair
Targeted repairs for membrane damage, seam failure, and standing water caused by poor drainage. Most low-slope leaks trace back to a seam or a blocked drain rather than the field of the roof, so we locate the source before patching anything.
Commercial Roof Replacement
Full system replacement built for durability and energy efficiency on flat and low-slope decks. We check insulation and slope to drain during tear-off, because a new membrane laid over an existing ponding problem fails the same way the last one did.
Commercial Roof Coating
Protective coatings that extend service life and restore waterproofing without a full tear-off. Worth pricing when the membrane is aging but the deck and insulation underneath are still sound.
High-Performance Roofing Systems Engineered for New Jersey Weather
Asphalt Shingles
The default on most roofs here and the cheapest to install, at 20 to 30 years. We set ice and water shield at the eaves and valleys, which is what stops a snow-holding slope from backing water under the field.
Metal Roofing
Sheds snow and ice better than anything else here, which is why it turns up on additions, porches, and outbuildings. Forty to seventy years, mid to upper range on cost, and metal against asphalt lays out the trade.
Cedar Roofing
Where a roof already has cedar, matching it is usually the requirement rather than the preference. Expect 30 to 40 years with upkeep, at an upper mid range price.
Copper Roofing
Almost always a detail material rather than a full roof: porch roofs, bay windows, dormers. Premium pricing, though the limited square footage keeps it reachable, and it will outlast 70 years.
Slate Roofing
Still in place on a fair number of homes in the borough. It costs more than anything else we install and returns 75 to 100+ years, and a slope failing in patches can often be restored rather than torn off, the same call we make in New Hope.
TPO Flat Roofing
Reflective single-ply for low-slope commercial decks, and the cheapest route to cutting cooling load on a flat roof. Fifteen to twenty-five years.
EPDM Rubber Roofing
The workhorse on flat additions and rear extensions. It stays flexible through freeze-thaw swings, runs 20 to 30 years, and sits at the low to mid end on cost.
Modified Bitumen Roofing
Multi-layer build for low-slope roofs that get walked on for HVAC or service access. Shortest life on this list at 15 to 20 years, and the least expensive flat system.
Exterior Improvements That Reinforce Your Roofing System
Gutter Replacement
Undersized gutters back up during heavy river-valley rain, so gutter installation is sized to the roof area draining into it.
Siding Replacement
Quality siding installation closes the wall-to-roof transition where wind-driven rain usually gets in.
Skylight Installation
Precision skylight installation adds light without creating the leak point most older skylights become.
Stucco Remediation
Trapped moisture behind stucco rots sheathing from the inside, and stucco remediation restores the drainage plane before it reaches framing.
Window & Door Installation
Energy-efficient window and door installation cuts drafts and reduces the attic moisture load that shortens roof life.

Straight Answers to Common Roofing Questions
Do I need a permit to replace a roof in Frenchtown?
Usually not. Straight replacement on a single-family home counts as ordinary maintenance in New Jersey. Structural work on decking or rafters changes that, and we check with the borough before scheduling.
Can you match the slate or cedar already on my roof?
Yes. We install both, and where budget or structure rules them out we source synthetic profiles that hold the original sightline.
Why do homes near the river get ice dams when others nearby do not?
Shaded north and east-facing slopes hold snow days longer than sun-exposed roofs a mile inland. Add a poorly ventilated attic and you have the conditions ice dams form in.
Do you work outside the borough, in Kingwood or Alexandria Township?
Yes. We cover the Route 12 corridor and the river road from Milford down to Stockton, townships included.
How fast can you get here after a storm?
We are twenty minutes away over the bridge in Bucks County. We tarp first and quote later, because the priority is keeping water off your ceilings.
One Leak Is Cheaper to Fix Than the Decking Under It
Water that reaches plank sheathing turns a repair into a tear-off, and it does that in a season, not a decade.
The inspection is free with nothing attached to it. We get on the roof, into the attic, and send you photos with a written estimate that prices repair and replacement separately. If the roof has a few more years in it, we will tell you that instead.
Serving Frenchtown and Surrounding Hunterdon County Communities
