Fast, Reliable Roof Replacement & Installation Across Dunellen
A full roof replacement on a typical Dunellen home runs $8,500-$18,000 depending on size, pitch, and how many layers need tearing off. Most Dunellen jobs we handle are completed in two to three days once materials arrive, and our crews are on the road to Middlesex County within the hour when you call. If you’re seeing water stains on your ceiling, missing shingles along North Avenue, or sagging at the eaves of your bungalow, waiting through another nor’easter season is a gamble you don’t need to take. Call (866) 756-1978 and a live person will pick up, day or night.
We’ve been climbing Dunellen roofs since the 1980s. We know the shallow-pitched capes off Lincoln Avenue, the dormered craftsmans near the train station, and the layered shingles that hide beneath on homes built before Eisenhower took office. That familiarity matters. A roofer who doesn’t recognize how Green Brook flooding changes the stakes here can miss the details that keep your basement dry.

Our Roof Replacement & Installation Services in Dunellen
Full Roof Replacement
Most Dunellen homes we replace are carrying two or three layers of asphalt shingles over original wood decking that has never seen proper ventilation. A full tear-off is non-negotiable here - we won’t roof over old layers, and we’ll show you why when we photograph the rot hiding beneath. Our Roof Replacement & Installation crew removes everything to the deck, replaces compromised sheathing, and installs complete water-shedding systems that address the kickout and step flashing failures so common in this borough’s pre-1950s housing stock.
New Construction Roofing
New builds in Dunellen are rare given the borough’s built-out character, but when they happen - additions, teardowns, or infill near the downtown corridor - we spec materials and ventilation systems suited to Central New Jersey’s freeze-thaw cycles and summer humidity. Proper ridge and soffit ventilation from day one prevents the granule loss and deck rot we see constantly on older homes that were never designed for airflow.
Asphalt Shingles
Asphalt remains the practical choice for Dunellen’s craftsman bungalows and modest colonials. We install IKO and Atlas architectural shingles with full manufacturer warranties, paired with synthetic underlayment and self-adhering ice-and-water barrier at all valleys and eaves. For homes near the Green Brook flood corridor, this combination of proper shingle installation and water-shedding details matters more than the shingle brand alone. A shingle is only as good as the flashing and underlayment beneath it.
Metal Roofing
Metal roofing suits Dunellen homeowners who plan to stay for decades and want to eliminate the reroofing cycle entirely. Standing seam systems shed snow loads efficiently and resist the wind uplift that stresses asphalt edges during nor’easters. We install Tamko metal products with proper fastening patterns for the shallow pitches common on Dunellen’s older homes, where standard installation methods can fail.
Flat Roofing
The low-slope sections on Dunellen’s older homes - porch roofs, rear additions, dormers - demand specialized flat roofing systems, not shingles pretending to work on a slope. We install modified bitumen and TPO membranes with proper drainage detailing, critical in a borough where poor water management compounds quickly with Green Brook flooding.
Tile Roofing
Some Dunellen homes retain original slate that deserves repair rather than replacement, and a few newer builds in the borough specify clay or concrete tile. We handle Boral tile products and slate repair through trained specialists, not general laborers who treat tile like heavy shingles.

Trusted Brands We Service in Dunellen
We are authorized installers for seven manufacturer lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Dunellen customers, this means we stock common shingle colors and accessory pieces locally, cutting wait times when you’re staring at a tarp and a weather forecast. We don’t substitute materials without your written approval, and we register every warranty directly with the manufacturer so there’s no paperwork for you to track down later. The brands we recommend for your specific roof depend on pitch, ventilation conditions, and whether your home sits in the flood-prone sections near Green Brook - not on what we have excess inventory of this month.
Common Roof Replacement & Installation Problems We See in Dunellen Homes
- Kickout and step flashing failures at dormers and valleys. On Dunellen’s pre-1950s homes, original flashing was often minimal or omitted entirely. Water runs behind gutters, soaks eaves, and ends up in basements already vulnerable to Green Brook flooding. We replace with integrated, weatherproof step flashing and proper kickout diverters.
- Ice damming along eave edges and in valleys. Central New Jersey nor’easters deliver snow loads that punish aging roofs. Multiple layers of old asphalt trap heat, melt snow unevenly, and create backup that penetrates beneath shingles. Modern ice-and-water barrier installation is essential.
- Granule loss and deck rot from inadequate ventilation. Pre-1960 Dunellen homes rarely have ridge vents or sufficient soffit intake. Summer humidity and heat cook shingles from below, accelerating deterioration that shows up as curling, cracking, and interior stains.
- Structural sag from overloaded decking. Two or three layers of shingles plus original wood decking near the end of its service life creates sagging ridges and valleys. We see this frequently on the cape cods and small colonials off Washington Avenue and Prospect Street.

What moves you within these ranges? Roof pitch matters - Dunellen’s steeper colonials take longer and require more safety setup. Deck condition matters more. We’ve stripped roofs on South Washington Avenue and found three layers over rotted planks that all needed replacement. That adds material and labor, but we quote it upfront, not halfway through the job. The number on our estimate is the number on your invoice. No surprises.
Every estimate is free, and we provide a written breakdown you can compare against any other bid. We also offer a free second opinion on any written estimate you’ve already received - a service Dunellen homeowners use more than you’d expect, especially after storm-chasing contractors roll through with high-pressure pitches.

FAQs - Roof Replacement & Installation in Dunellen
Because Dunellen’s pre-1950s housing stock and Green Brook flood corridor mean roof failures often start at flashing points, not the shingles themselves. Original construction on many bungalows and colonials used minimal or absent kickout flashing at dormer and wall junctions, allowing water to run behind gutters and soak eaves, fascia, and eventually the walls above basements already prone to flooding. Proper water-shedding details at these junctions prevent the hidden intrusion that compounds into structural damage. Call (866) 756-1978 and we’ll show you exactly what your flashing looks like from the roof - estimates are free.
Yes, and in most cases it’s required by New Jersey building code once you reach two layers. Dunellen homes frequently have multiple accumulated layers that trap heat, accelerate rot, and hide deck damage. We tear off to bare wood on every full replacement, replace compromised sheathing, and install modern underlayment and ventilation systems that perform properly. A roof-over might save a few hundred dollars today and cost thousands in trapped moisture damage within five years. Call (866) 756-1978 for a free inspection - we’ll photograph what you’re really walking on.
Synthetic underlayment paired with self-adhering ice-and-water barrier at all valleys, eaves, and penetrations. Central New Jersey’s January and February freeze-thaw cycles create expansion and contraction that felt underlayment cannot withstand; synthetic products remain flexible and provide a secondary water barrier if wind-driven rain gets past shingles. The ice-and-water barrier is particularly critical on Dunellen’s older homes with complex valley configurations and shallow pitches where snow sits longer. Call (866) 756-1978 and we’ll spec the right system for your roof geometry.
Yes, Dunellen requires a building permit for any roof replacement involving structural work, tear-off, or changes to roofline or materials. We handle permit application, scheduling, and inspection coordination as part of our standard process. Our familiarity with the Dunellen building department means we know the inspectors, their preferences for documentation, and how to keep your job moving without delays. You won’t need to take time off work to wait for inspections. Call (866) 756-1978 and we’ll walk you through the timeline.
Green Brook flooding makes proper roof water-shedding a higher-stakes decision in Dunellen than in drier-sited neighboring communities. When basements and crawl spaces already face groundwater pressure, any roof failure that sends additional water down exterior walls or into soffit cavities compounds the damage dramatically. We prioritize kickout flashing, valley drainage, and ice-and-water barrier installation on every Dunellen job because we’ve seen what happens when these details are treated as afterthoughts. The right roof doesn’t just keep rain out of your attic - it keeps water away from your foundation. Call (866) 756-1978 for a free assessment of your home’s water-shedding details.
We recently completed a full roof replacement on a 1920s craftsman bungalow on South Washington Avenue near the Green Brook. The original wood decking had significant rot from decades of inadequate kickout flashing at the dormer valleys, allowing water to run behind the gutters and soak the eaves. We installed GAF Timberline HD shingles with matching weatherproof step flashing, integrated a self-adhering ice-and-water barrier at all valleys and eaves, and added ridge vents to improve attic airflow - eliminating the chronic moisture issues the homeowners had battled for years.
