Full Tear-Off and What We Find Under Paterson Roofs
A real roof replacement starts by removing everything down to the wood — every shingle, every layer of old underlayment, and any prior overlay. We never roof over an existing roof in Paterson, and there's a reason: the city's older housing has often already been layered once or twice over the decades, and a fresh layer on top only hides what's failing underneath. Stripping to the deck is the only way to see — and fix — the part of the roof that actually keeps water out.
Once the deck is exposed, we inspect every board. On pre-1920 downtown and Eastside homes that often means plank decking — individual boards with gaps — where decades of slow leaks around chimneys, valleys, and old flashing have left soft, delaminated, or rotted wood. On post-war Wrigley Park and Hillcrest houses it's usually plywood or OSB sheathing, which can swell or rot where a flat porch roof or an old skylight let water track in. We replace any compromised decking before a single new layer goes down, because the best shingle in the world fails fast over rotten wood. Because decking replacement is impossible to fully predict from the ground, we explain up front how we handle it, and you see photos of anything we find.
Tear-off is also when the real condition of a Paterson roof becomes obvious — the unlined brick chimney with original step-flashing, the spot where a 1960s dormer was tied into older framing, the seam where a low-slope addition meets the main pitched roof. We document all of it so the new system is detailed correctly the first time. If a roof turns out to need more than full replacement can solve on its own, that's also when we'd flag it; for active leaks discovered before you're ready to replace, our Paterson roof repair crew can stabilize things in the meantime.
The Modern Roof System We Build From the Deck Up
A roof isn't a layer of shingles — it's a system, and each layer does a specific job. Once the deck is sound, we start at the eaves and valleys with a self-adhering ice-and-water shield, the membrane that protects the most leak-prone areas against wind-driven rain and the ice dams that form during New Jersey's freeze-thaw winters. Over the rest of the deck goes synthetic underlayment — lighter, tougher, and far more tear-resistant than the old felt paper — as a full secondary water barrier.
Next comes the metal: drip edge along the eaves and rakes, and new step-flashing and counter-flashing at every wall, chimney, and dormer. On Paterson's older homes this flashing work is often where the previous roof actually failed, so we don't reuse tired metal. Then the shingle assembly itself — a starter strip along the edges for wind resistance, the architectural shingle field, and a matching ridge cap. Tying the whole thing together is ventilation: balanced intake at the soffits or eaves and exhaust at the ridge, so the attic breathes, summer heat escapes, and winter moisture doesn't rot the new deck from below.
That ventilation piece matters more in Paterson than people expect. A lot of the city's housing has had additions, dormers, and finished attics added on top of older framing over the years, and ventilation rarely kept pace. Building a proper intake-and-exhaust path during replacement is what protects the new roof's lifespan — and it's part of what separates a full system from a crew that just lays shingles. Because we're certified with GAF, Owens Corning, and CertainTeed, installing the complete system the way the manufacturer specifies is also what lets us register the enhanced system warranties a one-off roofer typically can't offer.
Material Options for a Paterson Replacement
For the overwhelming majority of pitched Paterson roofs, an architectural asphalt shingle is the workhorse and the best value — GAF Timberline HDZ, Owens Corning Duration, or CertainTeed Landmark Pro. These are dimensional, wind-rated, and available in colors that suit everything from a plain 4th-ward ranch to a detailed period roofline near the Great Falls historic district. Designer and luxury shingle lines exist too, for homeowners who want the look of slate or shake on a distinctive home, and we'll show you the options. The deeper background on shingle systems lives on our asphalt shingle roofing page.
Not every Paterson roof is a shingle roof, though — and pretending otherwise is how leaks start. The city's dense downtown, its mill-era buildings, and its many two- and three-family homes mean a large share of roofs are flat or low-slope: main roofs, back-of-house additions, and porch decks. Those surfaces need a welded-seam membrane — TPO, EPDM rubber, or modified bitumen — not asphalt shingles, and they're built and detailed completely differently. Plenty of Paterson homes are a hybrid: a pitched main roof in shingles with a low-slope section that needs membrane. We handle both in one project and detail the tie-in seam properly; see our Paterson flat roofing page for how we approach the low-slope side.
Metal is the third path — standing-seam systems that last decades and suit modern or estate-style homes — though it's less common on Paterson's typical stock than on custom homes elsewhere in the county. Whatever the material, the goal of the conversation is the same: match the system to your building, your roofline, and how long you plan to own the home. Several factors drive where a replacement lands — roof size and pitch, the number of valleys and penetrations, how much decking needs replacing, whether there's a low-slope section, and the shingle line you choose — which is exactly why we quote every Paterson replacement in writing, line by line, after we've actually been on the roof.
What a Replacement Day Looks Like on a Paterson Street
Most single-roof replacements on a Paterson home are a one-to-three-day job, weather permitting. The crew arrives early and protects the property first — tarps over landscaping, plywood against the siding, and a plan for where the dumpster sits given the tight setbacks and street parking that come with dense city lots. Then the tear-off: the old roof comes off in sections, debris goes straight into the dumpster rather than piling on the lawn, and the exposed deck gets inspected and repaired the same day so it's never left open to weather.
From there the system goes back on in order — membrane and underlayment, flashing and edge metal, starter, field shingles, ridge cap, and ventilation — and the roof is buttoned up watertight before the crew leaves each day. We don't strip more roof than we can dry-in. At the end, cleanup is real cleanup: a magnetic sweep of the yard, driveway, and street for nails, a final debris check, and the dumpster hauled off. On a dense Paterson block that diligence matters — your neighbors' cars and your kids' driveway are a few feet away.
Throughout, you're not chasing anyone. We confirm the schedule in writing, handle the dumpster and material delivery, and keep you posted on what we found and what we did. If a nor'easter is what put you in this position in the first place, the replacement and the claim can run together — our Paterson storm damage and insurance claims team documents the damage and meets your adjuster on the roof so legitimate damage isn't under-counted.
Two- and Three-Family and Multi-Family Replacements
A large share of Paterson's housing is two- and three-family, much of it tenant-occupied, and replacing those roofs is routine work for us rather than an exception. The logistics are simply different: shared-wall buildings where one roof plane drains onto the next, tighter setbacks that limit how we stage materials and the dumpster, and the need to coordinate around tenants who are home during the day. We schedule with that in mind, keep shared entrances and driveways clear, and sequence the work so the building stays livable while we're on it.
The bigger difference is on paper: a true detached one- or two-family re-roof is usually permit-free ordinary maintenance, but any three-family, multi-family, or commercial roof needs a permit, as does new decking or framing — we confirm and pull whatever applies with Paterson's construction office, and the full Paterson permit rules lay out every case.
Many of these buildings also carry a flat or low-slope main roof or a low-slope rear section, which means the replacement is partly or wholly a membrane job. We build those to last and flash the parapets, drains, and the wall transition between a low-slope section and the pitched roof — our Paterson flat roofing page covers that detailing, and our Paterson roof installation page covers new construction, additions, and dormer work that goes beyond a straight replacement.
