SAME-DAY

Roof Repair

Leak repairs in New Gretna start at $350 for a simple fix. We find the source with a water test or thermal scan, repair the damage, and warranty the work. If the repair costs more than 30% of a replacement, we'll tell you.

storm damage repair
LICENSED

Storm Damage Repair

Wind speeds over 60 mph cause shingle tab lift and seal failure. Hail over 1" diameter causes fractures through the shingle mat to the fiberglass reinforcement. Our HAAG-trained inspectors know the difference between cosmetic damage and functional damage. That distinction determines your insurance payout.

New Roof Installation

We install new roofs on new construction, room additions, detached garages, and covered patios. Our New Gretna crews handle residential and light commercial. Standard install time is 1-3 days depending on size.

metal roofing
GUARANTEED

Metal Roofing

Corrugated metal and R-panel are cost-effective options for barns, detached shops, and covered patios in New Gretna. We install 29-gauge and 26-gauge corrugated with exposed fasteners using neoprene washer screws. For homes, we recommend 24-gauge standing seam with concealed fasteners. Cleaner look, no exposed fastener maintenance. DaVinci composite shake and slate profiles give you the metal longevity with a traditional New Jersey aesthetic.

INSURED

Shingle Roofing

GAF Timberline HDZ architectural shingles with StrikeZone nailing area. The highest-selling shingle in North America. Impact-rated to UL 2218 Class 4 when installed with the full GAF Roof System. Our New Gretna crews install Timberline in the full system configuration to qualify for Golden Pledge warranty. ASTM D3462 and D7158 Class H certified.

flat roofing
FREE ESTIMATE

Flat Roofing

PVC roofing membrane for New Gretna restaurants, commercial kitchens, and any rooftop near grease exhaust. PVC resists animal fats and chemical exposure that destroys TPO and EPDM. We install IB Roof Systems and Duro-Last PVC with heat-welded seams and custom-fabricated accessories. Built-up roofing (BUR) with 3-4 plies of fiberglass felt in hot asphalt is still the longest-proven flat roof system with a 30+ year track record in New Jersey.

commercial roofing
SAME-DAY

Commercial Roofing

TPO is our most-requested commercial membrane in New Jersey. Reflective, energy-efficient, and it welds together at the seams for a watertight bond. We install 60-mil and 80-mil systems with 15-20 year manufacturer warranties.

gutter installation
LICENSED

Gutter Installation

We install 5" and 6" seamless aluminum gutters in New Gretna. Standard homes get 5", high-volume areas and steeper pitches get 6". Downspouts every 30-40 ft of gutter run with splash blocks or underground drains.

roof inspection
TOP RATED

Roof Inspection

Our 27-point roof inspection covers: shingle condition, granule loss, nail pops, lifting tabs, ridge cap integrity, valley flashing, step flashing at walls, drip edge, pipe boot seals, vent function, soffit ventilation, gutter pitch, downspout capacity, fascia condition, decking (from attic if accessible), and visible signs of moisture in the attic. Written report with photos emailed same day.

emergency roof repair
GUARANTEED

Emergency Roof Repair

Emergency roof repairs for active water intrusion follow a strict protocol: tarping with reinforced polyethylene sheeting secured to the roof deck, interior water extraction guidance, and temporary flashing at penetrations. Our New Gretna emergency crews carry 20x30 tarps, 2x4 nailer boards, and masonry anchors for various deck types. Permanent repairs are scheduled within 48-72 hours once materials are sourced.

skylight installation
INSURED

Skylight Installation

VELUX FS fixed skylights and VS vented skylights installed with EDL flashing kits for profile roofing. The flashing integrates with your shingle courses per IRC R903.2 weather protection requirements. We cut the opening, frame the curb with doubled 2x lumber, install the skylight with factory sealant, and weave the flashing into the existing shingle field. Leak-proof when done right. And we do it right in New Gretna.

Simple Process

How It Works

1

Roof Evaluation

We climb up, walk the entire roof, and document what we find with photos and measurements. Takes about 30 minutes. You'll see exactly what we see.

2

Written Estimate

We price by the roofing square with all materials itemized. You'll see exactly what you're getting. Shingle brand, underlayment type, ventilation specs, flashing details.

3

Build Day

No subcontractors. Our crews, our equipment, our supervision. A project manager checks in throughout the day and does a final quality inspection before cleanup.

4

Final Walkthrough

Before we leave: magnetic nail sweep across the entire yard, driveway, and walkways. Dump trailer hauled off. Gutters cleaned out. Your property looks better than when we arrived.

"Got three quotes for a roof replacement. New Gretna Roofing & Maintenance was the middle price but the only one who actually got on the roof and showed me photos. Everyone else just eyeballed it from the driveway."

"Asked for a second opinion because another company said I needed a full replacement. New Gretna Roofing & Maintenance said I only needed valley flashing repair and some shingle replacement. Saved me about $14,000. I trust these guys."

FAQ

Frequently Asked Questions

Age is the biggest factor. If your shingles are 20+ years old and you're seeing curling, cracking, or granule buildup in the gutters, it's time. Other red flags: leaks, missing shingles, daylight in the attic, and your neighbors all getting new roofs (same-age homes in a subdivision often need replacement around the same time).

One day for most homes. Our crews are experienced and we pre-stage materials the day before install. Bigger or steeper roofs can run to two days. The dumpster shows up at 7 AM and leaves when we're done. Your life gets back to normal fast.

The shingles carry the manufacturer's warranty. Typically 30-50 years for architectural shingles. Our installation warranty covers any defects in our workmanship. If something goes wrong because of how we installed it, we fix it at no cost. Both warranties are in writing and we provide them at the final walkthrough.

Here's the process: we inspect your roof for free, document any storm damage with photos, and help you file the claim. Your insurance company sends an adjuster. We meet them on-site and walk the roof together. If approved, we do the work at the agreed price. If the estimate seems low, we supplement it with additional documentation.

Catch the water with a bucket, move valuables out of the drip zone, and call us at (877) 586-1316. Don't get on the roof yourself. It's dangerous and you probably can't fix it permanently anyway. We respond to emergency leaks within 24 hours in New Gretna and tarp the area to stop further damage.
