What's Included

Every Flat Roof Service Includes These 5 Things

When you book a flat roof job with us, you're not just getting new membrane. We've built a repeatable system that covers every detail, from tear-off to final inspection — no surprises, no cut corners.

    • Full Tear-Off & Deck Prep – We strip down to the structural deck, remove all old layers, and inspect for rot or soft spots. Any damaged plywood gets replaced before we lay a single square of new membrane.
    • High-Performance Membrane – We install TPO, PVC, or modified bitumen (your choice, based on your budget and building use). We're factory-certified for Malarkey, GAF, CertainTeed, and Owens Corning flat systems.
    • Seam Welding & Flashing – Every seam is heat-welded (no glue joints that fail in 3 years). All penetrations — vents, drains, skylights — get custom metal flashing and counter-flashing for a watertight seal.
    • Drainage & Slope Correction – We verify positive drainage to all roof drains and scuppers. If your roof has standing water, we'll add lightweight slope fill to eliminate ponding — a common cause of premature failure.
    • 20-Year Workmanship Warranty – Every flat roof we install comes with our own 20-year workmanship guarantee, plus the manufacturer's material warranty. We stand behind the work because we do it right the first time.

Real Flat Roof Job in Paterson

How We Replaced a Leaking Flat Roof on East 18th Street

Last fall, a homeowner on East 18th Street called us about a persistent leak over their living room. We found the old modified bitumen roof was cracked and ponding water. Here's what we did.

In October 2024, we replaced a 1,200-square-foot flat roof on a split-level home in Paterson's Eastside neighborhood. The original roof was 15-year-old modified bitumen with multiple patches that had failed. We tore off all three layers down to the wood deck, replaced 4 sheets of rotted plywood, and installed a new TPO membrane system from GAF. The homeowner chose a white membrane to reflect heat and lower cooling costs. We finished with new edge metal, seamless gutters, and a 20-year workmanship warranty. Total cost was $8,400. The job took two days, and we had a tarp on the same day we inspected. No more leaks.

Quick Answers

Flat Roofing Questions – Answered Straight

We’ve been nailing roofs in Paterson since 2008, so we’ve heard every flat-roof question there is. Here’s the real deal on materials, costs, and what to expect when you work with us.

What flat roofing materials do you use?

We install TPO, EPDM, and modified bitumen—all from top manufacturers like GAF, CertainTeed, and Owens Corning. For Paterson homes and businesses, TPO is our go-to for its durability and energy efficiency. We’ll walk you through the best option for your roof during a free inspection.

How much does flat roof replacement cost in Paterson?

Cost varies by size, material, and condition of your existing roof. On average, homeowners in Passaic County pay between $4,000 and $8,000 for a standard flat roof replacement. We give free, no-obligation estimates after a same-day inspection—no surprises.

Can you repair a flat roof, or does it need full replacement?

It depends. Small leaks or punctures can often be repaired with patches or sealants. But if the membrane is old or there’s widespread blistering, a full replacement is usually more cost-effective in the long run. We’ll tell you honestly which route saves you money.

How long does a flat roof last?

A properly installed TPO or EPDM roof can last 20–30 years. Modified bitumen roofs typically last 15–20 years. We back all our replacements with a 20-year workmanship warranty, so you’re covered long-term.

Do you handle insurance claims for storm-damaged flat roofs?

Yes, we’re storm damage specialists. We’ve helped homeowners in Eastside Paterson and Lakeview Clifton navigate claims from start to finish—including hail and wind damage. We’ll inspect your roof, document the damage, and work with your adjuster to get you a fair settlement.

Is flat roofing good for Paterson’s climate?

Absolutely. Modern flat roofs are designed to handle heavy rain and snow loads common in North Jersey. With proper drainage and a quality membrane, they outperform many sloped roofs in durability. We’ve installed dozens in Packanack Lake Wayne that have held up through Nor’easters.

How long does a flat roof installation take?

Most residential flat roof replacements take 2–4 days, depending on size and weather. We schedule around your timeline and keep the site clean—no debris left behind. You’ll get a same-day report after the inspection, and we’ll set a start date right away.
