What Is Asphalt Shingle Roof Replacement?
Asphalt shingle roof replacement strips an existing roof to the deck and installs new asphalt shingles, in either the three-tab or architectural type, over fresh underlayment. It rebuilds the full shingle system rather than overlaying or patching the old covering.
What Asphalt Shingle Roof Replacement Do We Provide?

Newark Quality Roofing replaces 2 asphalt shingle types across Essex County: 3-tab shingles and architectural (laminated) shingles — for residential and steep-slope commercial properties. Asphalt shingle roof replacement strips the existing roof to the deck, repairs the sheathing, installs an ice barrier and synthetic underlayment, and installs new asphalt shingles, the work that ends an aged asphalt roof rather than patching a single failed detail.
Asphalt shingles cover roughly 73% of US residential roofs per 2024 roofing-market data, the most common roof covering Newark Quality Roofing installs. A 3-tab asphalt roof lasts 20 years and an architectural asphalt roof lasts 30 years, per the InterNACHI life-expectancy chart, and the NRCA notes the actual asphalt service life varies up to 40% with climate, install, and maintenance. A Newark Quality Roofing replacement matches the shingle line and wind rating to the building and the Essex County climate before tear-off.
- 3-tab asphalt shingle replacement — 3-tab asphalt shingle replacement installs flat single-tab shingles that last 20 years and carry roughly a 60 mph wind rating, the ASTM D3161 Class A class, per the InterNACHI life-expectancy chart and ARMA wind-class guidance.
- Architectural asphalt shingle replacement — Architectural asphalt shingle replacement installs laminated dimensional shingles that last 30 years and carry a wind warranty up to 130 mph with 6-nail installation, per the InterNACHI life-expectancy chart and ARMA and manufacturer wind-class guidance.
- Tear-off and deck repair — Tear-off and deck repair strips the existing asphalt roof to the bare sheathing and replaces deteriorated plywood or OSB, the removal the NJ Rehabilitation Subcode requires when the covering is water-soaked or the roof already carries 2 or more layers, per N.J.A.C. 5:23-6.4.
- Ice barrier and underlayment installation — Ice barrier and underlayment installation applies a self-adhering ice barrier at the eaves and synthetic underlayment across the deck, because the IRC ice-barrier provision (R905.1.2) requires an ice barrier from the eave to a point at least 24 inches inside the exterior wall line in ice-prone climates, per the International Residential Code.
How Do You Know If You Need Asphalt Shingle Roof Replacement?




- An asphalt roof at or past its material lifespan signals replacement, because a 3-tab asphalt roof lasts 20 years and an architectural asphalt roof lasts 30 years, and the actual life varies up to 40% with climate and maintenance, per the InterNACHI life-expectancy chart and the NRCA.
- Granule loss with sandy grit in gutters and bald asphalt mat indicates shingles nearing end of life; granule loss exceeding 30% of the surface is the common rule-of-thumb for beyond repair, and 50% loss cuts remaining life by up to 70%, per GAF.
- Damage across more than 25–30% of the roof area crosses the contractor-consensus 25% rule, the threshold above which full replacement costs less than continued spot repair, per roofing industry guidance.
- Curling, cupping, and zipper cracking along the shingle cutouts indicate advanced asphalt degradation from thermal cycling and aging, per GAF and InterNACHI inspection guidance.
- Three or more repairs in 2 years signals systemic asphalt failure rather than an isolated defect, the contractor-consensus 3-repairs rule that favors replacement, per roofing industry guidance.
- A spongy or sagging roof deck under the asphalt indicates moisture-rotted sheathing, a structural condition that points toward tear-off and deck replacement rather than a surface patch, per GAF inspection guidance.
- Daylight through the roof deck seen from inside the attic indicates holes in the decking and shingles, a sign that points toward replacement rather than a patch, per This Old House.
- An asphalt roof past 20 years, or 15 on the coast, favors replacement, because a localized repair can cost 5 to 10 times less than replacement only while the asphalt roof stays under 10 to 15 years old, per Home Depot and Kelly Roofing cost data.

How Do Our Roofing Contractors Perform Asphalt Shingle Roof Replacement?

Newark Quality Roofing matches the asphalt shingle line and wind rating to the building from 2 shingle types: 3-tab shingles at a 20-year life and architectural shingles at a 30-year life. A 3-tab asphalt roof lasts 20 years and an architectural asphalt roof lasts 30 years, per the InterNACHI life-expectancy chart, and ASTM D3161 sets the asphalt wind classes — Class A near 60 mph and Class F near 110 mph — while many architectural lines warranty to 130 mph with 6-nail installation, per ARMA and manufacturer guidance. Newark Quality Roofing installs GAF, Owens Corning, and CertainTeed asphalt shingle systems.
Newark Quality Roofing assesses the roof deck, the attic ventilation, and the NJ code triggers before quoting an asphalt replacement, because a tear-off exposes deck rot, undersized ventilation, and structural conditions a surface inspection misses. The NRCA and ARMA specify 1 square foot of net-free vent area per 150 square feet of attic floor, and proper attic ventilation reduces the heat and moisture stress that shortens roof life, per the NRCA, so a Newark Quality Roofing assessment corrects undersized ventilation as part of the asphalt replacement. A structural change to rafters or trusses triggers a permit under N.J.A.C. 5:23-2.7, separate from the ordinary-maintenance re-roof exemption, per the NJ Uniform Construction Code.
Newark Quality Roofing strips the asphalt roof to the deck, repairs the sheathing, installs an ice barrier and synthetic underlayment, and installs the shingles to manufacturer specification, the sequence that keeps the manufacturer system warranty intact. The IRC ice-barrier provision (R905.1.2) requires a self-adhering ice barrier from the eave to a point at least 24 inches inside the exterior wall line in ice-prone climates, per the International Residential Code, and Newark crosses the 32°F freezing point repeatedly through winter, driving freeze-thaw stress on the shingle seals. Installing to manufacturer specification preserves the material warranty covering factory defects, separate from the written workmanship warranty backing the labor, per Owens Corning warranty guidance.
What Residential Asphalt Shingle Roof Replacement Do We Provide?
Newark Quality Roofing replaces residential asphalt shingle roofs across Essex County, re-roofing detached one- and two-family homes with 3-tab or architectural shingles and no construction permit required for the roof covering. A complete tear-off and replacement of the roof covering on a detached one- and two-family dwelling counts as ordinary maintenance under N.J.A.C. 5:23-2.7 and requires no construction permit, no inspection, and no notice to the construction official, per the NJ Uniform Construction Code, while a structural change to rafters or trusses still triggers a permit.
A new asphalt roof recoups roughly 60 to 68% of project cost at resale, per a Zillow resale analysis, so an asphalt replacement returns value at sale as well as ending the leak risk. A Newark Quality Roofing residential asphalt replacement installs an ice barrier at the eaves per the IRC R905.1.2 provision, replaces decking rotted under the old shingles, and contains debris with ground tarps and a magnet sweep for nails before leaving the property across Newark, East Orange, Bloomfield, Montclair, Belleville, Irvington, and Glen Ridge. A storm-driven asphalt replacement documents the damage with timestamped photographs for the insurance adjuster, because Newark Quality Roofing inspects and documents the damage and performs the approved work while the homeowner files and negotiates the claim.

What Commercial Asphalt Shingle Roof Replacement Do We Provide?
Newark Quality Roofing installs asphalt shingles on steep-slope commercial and mixed-use roofs across Essex County, the same 3-tab and architectural systems used on residential roofs where the roof slope sheds water. Asphalt shingles suit a steep-slope commercial roof, while a low-slope commercial roof drains too slowly for shingles and uses a membrane system instead, because a low-slope roof needs at least ¼ inch per foot of slope to drain, per the NRCA and ARMA.
On a commercial building, an asphalt roof replacement requires a permit under N.J.A.C. 5:23-2.7, because the ordinary-maintenance exemption covers only the repair of up to 25% of the total roof area in a 12-month period, per the NJ Uniform Construction Code. A flat or low-slope commercial roof uses EPDM, TPO, or modified-bitumen membrane rather than asphalt shingles, the low-slope systems Newark Quality Roofing services on the flat-roof replacement scope.

What Are the Steps in Our Asphalt Shingle Roof Replacement Process?

- Deck, Ventilation, and Shingle Assessment
A Newark Quality Roofing technician inspects the roof deck, the attic ventilation, and the existing asphalt covering, sizing ventilation against the NRCA and ARMA standard of 1 square foot of net-free vent area per 150 square feet of attic floor before quoting the asphalt replacement.
- Written Estimate and Shingle Selection
A Newark Quality Roofing written estimate sets the scope, labor, materials, and timeline and presents the shingle options from 2 types — 3-tab at a 20-year life and architectural at a 30-year life — with the wind rating of each named, naming GAF, Owens Corning, and CertainTeed lines, per Integrity Home Exteriors documentation guidance.
- Permits and Material Ordering
A Newark Quality Roofing crew files the construction permit when the job triggers one — a commercial roof or a structural change — separate from the detached one- and two-family ordinary-maintenance exemption under N.J.A.C. 5:23-2.7, and orders the shingles to arrive on the scheduled start date, per the NJ Uniform Construction Code.
- Tear-Off and Deck Repair
A Newark Quality Roofing crew strips the existing asphalt roof to the bare sheathing, inspects every section, and replaces deteriorated plywood or OSB, with complete removal required by N.J.A.C. 5:23-6.4 when the roof is water-soaked or already carries 2 or more layers.
- Ice Barrier, Underlayment, and Shingle Installation
A Newark Quality Roofing crew installs the ice barrier from the eave to a point at least 24 inches inside the exterior wall line per the IRC R905.1.2 provision, applies synthetic underlayment across the deck, and installs the asphalt shingles to manufacturer specification with the specified nail pattern that keeps the wind warranty intact.
- Verification, Cleanup, and Warranty
A Newark Quality Roofing lead verifies the install against manufacturer specification, runs a magnet sweep for nails at cleanup, and issues a written workmanship warranty on the labor, separate from the manufacturer material warranty, per Integrity Home Exteriors verification and Owens Corning warranty guidance.

- Tear-off and deck repair add cost when the roof carries 2 or more existing layers or the sheathing is deteriorated, because N.J.A.C. 5:23-6.4 requires full removal of a multi-layer or water-soaked roof, per the NJ Rehabilitation Subcode.
- Labor accounts for roughly 60–70% of an asphalt-install total, and NJ ranges sit 10–40% above national figures because of higher labor and stricter NJ code, per HomeGuide and Integrity Home Exteriors.
