Asphalt shingles cover the overwhelming majority of New Jersey homes — but metal roofing keeps gaining ground, and for good reasons. If you're deciding between them, the right answer depends on how long you plan to stay, your budget, and your tolerance for upfront cost versus long-term value. Here's the honest comparison.
Upfront cost
This is where asphalt wins clearly. Architectural asphalt shingles install for roughly $4.50–$7.00 per square foot in NJ, putting a typical 1,700 sq ft roof in the $9,000–$15,000 range. Standing-seam metal runs $9–$17 per square foot — frequently double the asphalt price or more, so the same roof can land between $18,000 and $30,000.
For a homeowner focused purely on the cheapest path to a sound, code-compliant roof, asphalt is the answer. The metal conversation is really about long-term math, not upfront math.
Lifespan — and the long-term math
A quality architectural asphalt roof lasts about 25–30 years in NJ's climate. Metal lasts 40–70 years. Over the life of a home, that often means installing two or three asphalt roofs in the time one metal roof serves — and when you spread metal's higher cost across its much longer life, the annual cost can actually come out lower. The catch: you only capture that value if you stay in the home long enough, or if a future buyer pays a premium for the remaining decades of roof life.
Snow and ice performance
New Jersey winters matter here. Metal's smooth surface sheds snow readily, reducing the snow load that builds on a roof and lessening ice-dam risk at the eaves. Asphalt holds snow longer, which contributes to the ice dams that are a chronic NJ problem in cold snaps. Many metal installs add snow guards specifically to control where shed snow lands so it doesn't avalanche onto walkways or landscaping below.
Wind and storm resistance
Both can be rated for NJ wind speeds — asphalt shingles are tested to ASTM standards and labeled with a wind classification, and quality architectural shingles handle typical NJ storms well when properly installed. But coastal and inland NJ storm events routinely exceed 60 mph, and a properly installed standing-seam metal roof, with its concealed fasteners and interlocking panels, generally has the edge in extreme wind. For shore-adjacent homes, that resilience is a real consideration.

The noise myth
The biggest misconception about metal roofing is that it's loud in the rain. That image comes from metal over an open barn structure. On a home with solid decking, underlayment, and attic insulation, a metal roof is no louder than asphalt in a storm. Don't let the noise myth steer your decision.
Appearance and curb appeal
Asphalt offers the widest range of looks and colors and reads as "expected" on most NJ streets, which can matter for resale in traditional neighborhoods. Modern metal comes in standing-seam profiles and even metal shingles that mimic slate or shake, and it carries a clean, premium look that many buyers now actively want. Some HOAs and historic districts in NJ restrict materials, so check local rules before committing to either.
Energy efficiency
Metal reflects solar heat rather than absorbing it, which can reduce attic heat gain and summer cooling costs — a real benefit in NJ's hot, humid summers. Asphalt absorbs more heat, though lighter "cool roof" shingle colors narrow the gap. If summer energy bills are a pain point, metal's reflectivity is a point in its favor.
Maintenance
Both are low-maintenance compared to wood or tile. Asphalt may need occasional shingle repairs and benefits from keeping moss and algae in check. Metal needs little beyond keeping debris out of valleys and occasional fastener checks on exposed-fastener systems (standing-seam hides its fasteners, which is why it lasts longer). Neither demands much from a homeowner who keeps gutters clear.
Resale value
A new roof of either type helps at resale by removing the "old roof" objection. Metal can command a premium with buyers who value its longevity, but it's also a bigger upfront spend you may not fully recoup if you sell soon after installing it. Asphalt's lower cost and universal acceptance make it the safer resale play for shorter ownership horizons.
So which should you choose?
Choose asphalt if you want the lowest upfront cost, you might move within 10–15 years, or you want a traditional look that matches your neighborhood. It's the right answer for most NJ homeowners, which is why most NJ roofs are asphalt.
Choose metal if you're staying long-term, you want to install once and never think about it again, you value snow-shedding and extreme-wind performance, or you want the energy and curb-appeal benefits and the budget allows for the higher upfront cost.
Frequently asked questions
Can you install metal over existing shingles?
In some cases metal can go over a single layer of asphalt with proper preparation, but a tear-off is often recommended so the deck can be inspected. We'll assess your specific roof and tell you what's appropriate.
Is metal roofing too heavy for my house?
The opposite — metal is generally lighter than asphalt and far lighter than slate or tile, so weight is rarely an issue for a typical NJ home.
Does metal roofing attract lightning?
No. Metal roofing does not increase the likelihood of a lightning strike, and if struck, it's non-combustible and can actually disperse the energy more safely than some materials.
What about the in-between option: metal shingles?
It's not strictly asphalt-or-metal. Metal shingles and stone-coated steel split the difference — they install more like traditional roofing and can mimic the look of slate, shake, or tile, while delivering metal's longevity and fire resistance. They typically cost less than standing-seam but more than asphalt. For a NJ homeowner who wants metal's durability without the distinctly modern standing-seam look, they're worth asking about. The trade-off is that some exposed-fastener metal-shingle systems need more fastener maintenance over time than concealed standing-seam.
Lifespan vs. how long you'll stay — the deciding question
If we had to reduce the whole decision to one question, it's this: how long will you own the home? If the answer is "5–12 years," asphalt almost always wins — you'll never recoup metal's premium, and asphalt will easily outlast your ownership. If the answer is "this is our forever home" or "20+ years," metal's longer life and lower lifetime cost start to make real financial sense, and you get decades of not thinking about your roof. Everything else — snow shedding, wind resistance, energy savings — is a tiebreaker on top of that core question.
