Why Ridgeline Roofing Co. of New York City Is Dunellen’s Preferred Roof Repair Company
We’ve been climbing Dunellen roofs for over 42 years. The craftsman bungalows along Grant Avenue, the cape cods near Columbia Park, the colonials tucked behind North Avenue - we’ve worked on all of them, and we know the repeated trouble spots that borough inspectors flag.
Our technicians are background-checked, uniformed, and trained to document every inspection with photos taken from your actual roof, not from the driveway. Dunellen homeowners call us back because we explain what we found, show the pictures, and quote one number that matches the final invoice. No surprises. No paperwork runaround if something needs adjustment - our 90-Day Done Right Promise means we come back and make it right, period.
Response time matters in a one-square-mile borough where a small leak can saturate original wood decking fast. We keep materials stocked for Dunellen’s common roof types, including matching slate and copper flashing, so most repairs don’t wait on special orders.
Named for the ridge - the line where a roof proves itself. That’s where we do our work.
Our Roof Repair Services in Dunellen
Shingle Replacement
Dunellen’s older colonials and bungalows often carry two or three layers of asphalt shingles over original wood decking. That accumulated weight traps moisture and accelerates rot. We strip to bare deck when needed, replace compromised plywood, and install new shingles to current code. For homes with viable single-layer coverage, we match existing CertainTeed or Owens Corning products for a seamless repair. A typical shingle replacement on a Dunellen bungalow runs $350-$850.
Leak Repair
Leaks in Dunellen rarely travel straight down. The borough’s shallow-pitch roofs and complex dormers send water sideways, making the entry point hard to locate from inside. We trace the path, repair the source, and check adjacent decking for saturation. After Green Brook flooding events, we see kickout flashing failures that let water run behind siding and into crawl spaces - a roof repair, not a siding issue, though the symptoms look similar. Most leak repairs in Dunellen fall between $250-$680.
Flashing Repair
Flashing is where Dunellen roofs live or die. Step flashing at dormers, valley pans in slate roofs, and kickout diverters at wall junctions all take punishment from Central Jersey’s freeze-thaw cycles. Original lead flashing on 1920s homes has often hardened and cracked; we fabricate custom copper replacements where needed. We recently repaired a legacy slate valley on a 1920s craftsman bungalow on West Front Street, where decades-old lead flashing had cracked and was directing water into the attic. Using matching Vermont unfading purple slate and a custom-fabricated copper valley pan, we restored full water-shedding without altering the home’s historic roofline. Flashing repair in Dunellen typically costs $280-$750.
Flat Roof Patch
Some Dunellen bungalows retain original tar-and-gravel flat sections over porches or additions. These require different technique than pitched-roof work. We clean to sound substrate, apply modified bitumen or appropriate membrane, and ensure drainage doesn’t pond. Flat roof patches in Dunellen run $400-$1,200 depending on area and substrate condition.

Common Roof Repair Problems We See in Dunellen Homes
- Ice damming at eave edges on shallow-pitch cape cods. Dunellen’s 1950s capes often lack modern ice-and-water barrier. Back-to-back freeze-thaw cycles through January and February push water uphill under shingles, saturating insulation and drywall below.
- Multiple asphalt layers trapping moisture against original wood decking. Three or more accumulated shingle layers are common on Dunellen’s pre-war homes. The weight alone stresses structure; the trapped humidity rots decking from the inside out, requiring full tear-off before any repair will hold.
- Kickout flashing failures at dormer-to-wall junctions on bungalows. Green Brook flood events compound any weakness here. Water runs behind siding, into crawl spaces, and breeds mold before homeowners notice interior staining.
- Granule loss and deck rot from inadequate ventilation. Pre-1960 Dunellen homes rarely have properly sized soffit intake or ridge exhaust. Summer humidity bakes attic spaces, accelerating shingle degradation and rotting the deck from below.

FAQs - Roof Repair in Dunellen
Single cracked slates can be repaired without replacing the entire roof. We remove the damaged tile, install a stainless steel hook or nail, and bed the replacement in matching Vermont unfading purple slate that maintains your home’s historic character. Full replacement is only necessary when multiple valleys fail, decking rots extensively, or the slate itself has reached end of life - typically 75-100 years. Call (866) 756-1978 and we’ll inspect to give you an honest assessment - estimates are free.
That’s almost certainly a roof repair, specifically a flashing failure. Flood events in Dunellen expose weaknesses in kickout and step flashing that let water run behind siding and emerge at the eaves. The water path makes it look like a siding problem, but the source is upstream at the roof-wall junction. We trace the actual entry point, repair the flashing, and verify with water testing. Call (866) 756-1978 - we’ll sort out what’s really happening.
Valley and eave-edge flashing replacement is the most common repair on Dunellen’s 1950s colonials. These homes were built before modern ice-and-water barrier became standard, and their valleys see heavy runoff from shallow pitches. After 70 years, original galvanized flashing has corroded, and freeze-thaw cycles have opened seams that admit water. Most of these repairs run $450-$900 and are completed in one day.
Yes, provided the underlying substrate is sound. We remove saturated gravel and failed tar, inspect the decking for rot, then apply modified bitumen or appropriate membrane with proper slope for drainage. Original tar-and-gravel in Dunellen is often 50-80 years old, so we assess whether patch or full replacement makes financial sense. A typical patch runs $400-$1,200. Call for a free evaluation.
Yes, virtually all pre-1960 Dunellen homes have inadequate soffit ventilation by current standards. Original construction typically included small, intermittent vents or none at all. Summer heat and humidity build in attics, baking shingles from below and trapping moisture that rots decking. We can add continuous soffit intake and verify ridge exhaust without altering exterior appearance - a repair that protects your roof from the inside out. Most ventilation improvements run $600-$1,400.
