What Are the Main Roofing Materials?
The main roofing materials are asphalt shingle, metal, natural slate, clay or concrete tile, and cedar shake for steep slopes, plus membrane systems for low slopes — each carrying a distinct lifespan, weight, and cost.
What Roofing Materials Does Newark Quality Roofing Install?
Newark Quality Roofing installs six roofing materials across Newark and Essex County, New Jersey: asphalt shingle, metal, natural slate, clay or concrete tile, and cedar shake on steep slopes, plus membrane systems on low slopes. Newark Quality Roofing is a roofing contractor and registered New Jersey Home Improvement Contractor.
Asphalt shingle, metal, slate, tile, and cedar shake cover steep-slope roofs pitched above 3:12 — the architectural-shingle, standing-seam metal, and natural-slate roofs common across Newark, Montclair, and the Caldwells. Asphalt shingle holds the largest share of New Jersey residential roofs; slate and tile carry the heaviest dead load and define many of Essex County's historic homes.
Membrane systems cover low-slope roofs pitched at 3:12 or less, the flat decks on Newark row buildings, additions, and commercial structures. Per the NRCA, low-slope roofs require positive drainage, so Newark Quality Roofing installs single-ply membranes — TPO, EPDM, and PVC — alongside modified bitumen, built-up roofing (BUR), and spray polyurethane foam (SPF) that shed water to interior drains and scuppers.
Each roofing material matches a slope, a budget, and a home style: a registered New Jersey Home Improvement Contractor specifies asphalt for cost, metal for span, slate or tile for historic-district homes, cedar for shake-style roofs, and membrane for the flat decks that asphalt and slate cannot serve.
How Do Asphalt, Metal, Slate, Tile, and Cedar Compare?
Asphalt, metal, slate, tile, and cedar differ most in service life: architectural asphalt lasts roughly 25–30 years, metal 40–70 years, natural slate 75–150-plus years, clay or concrete tile 50–100 years, and cedar shake 25–30 years, per InterNACHI.
Asphalt shingle and cedar shake share the shortest service life at roughly 25–30 years, but differ in cost and weight: architectural asphalt is the lowest-cost steep-slope material and the lightest mainstream option, while cedar shake costs more, weighs more, and demands more upkeep against rot in New Jersey's humidity.
Metal lasts roughly 40–70 years, per InterNACHI service-life ranges — longer than asphalt or cedar — and sheds snow and ice with a smooth standing-seam profile, unlike the granular surface of asphalt that holds snow longer.
Natural slate and clay or concrete tile carry the longest service life and the heaviest weight: slate lasts 75–150-plus years and tile 50–100 years, per InterNACHI, against asphalt's 25–30. Both load a roof structure far beyond asphalt or metal, so slate and tile suit homes engineered for the dead weight, a point a registered New Jersey Home Improvement Contractor verifies before specifying either.
Which Roofing Materials Suit New Jersey's Climate?
New Jersey's freeze-thaw cycles, snow load, wind, and humidity favor materials that resist water intrusion: metal and slate shed snow and last decades, while CRRC-rated reflective membranes cut heat gain on low-slope roofs.
Freeze-thaw cycles and snow load drive water behind shingles and stress the deck across Essex County, New Jersey winters; metal sheds snow with a smooth standing-seam surface, and slate's 75–150-plus-year life resists the repeated freeze-thaw that shortens shorter-lived materials.
Wind and humidity test fastening and rot resistance: New Jersey's coastal-influenced wind exposure rewards mechanically fastened metal and properly nailed architectural asphalt, while humidity accelerates rot in cedar shake, the material that demands the most maintenance of the six.
CRRC-rated reflective membranes address summer heat gain on low-slope roofs: the Cool Roof Rating Council rates membranes and coatings for solar reflectance and thermal emittance, and a reflective coating adds reflectance, not R-value — a distinction Newark Quality Roofing states before recommending a cool-roof system on a flat Newark, New Jersey deck.

What Questions Do Homeowners Ask About Roofing Materials?
Which roofing material lasts the longest?
Natural slate lasts the longest among common roofing materials at roughly 75–150-plus years, per InterNACHI service-life ranges, followed by clay or concrete tile at 50–100 years and metal at 40–70 years. Architectural asphalt and cedar shake last about 25–30 years.
What roofing materials work on a flat or low-slope roof?
Flat and low-slope roofs — pitched at 3:12 or less — take membrane systems: single-ply TPO, EPDM, and PVC, plus modified bitumen, built-up roofing (BUR), and spray polyurethane foam (SPF). Per the NRCA, low-slope roofs require positive drainage, because ponding water accelerates membrane aging.
Does a new asphalt roof in New Jersey need a permit?
A re-roof on a detached one- or two-family home is ordinary maintenance under N.J.A.C. 5:23-2.7 and needs no construction permit. Commercial and multi-family reroofs follow the New Jersey Uniform Construction Code, and recover is limited by the Rehab Subcode.
Can a new roof go over the existing layer?
The New Jersey Rehab Subcode, N.J.A.C. 5:23-6.4, limits roof recover: no new layer goes over two existing layers, over wet or deteriorated decking, or over wood shake. The rule mirrors IRC R908, so Newark Quality Roofing inspects the deck first.
Are reflective cool roofs worth it in Essex County, New Jersey?
Reflective cool roofs cut summer heat gain on low-slope roofs, rated by the Cool Roof Rating Council for solar reflectance and thermal emittance. A reflective coating adds reflectance, not R-value, so Newark Quality Roofing pairs it with proper insulation on Essex County, New Jersey decks.
