Asphalt Shingles vs Metal Roofing on Long Island
Two of the most popular roofing options for Long Island homeowners, compared head-to-head on cost, lifespan, weather performance, and total value.
The Two Best Options for Long Island Roofs
If you are replacing a roof on Long Island, your two best options are architectural asphalt shingles and metal roofing. Together, they account for the vast majority of residential roof installations in Nassau and Suffolk County. Each has clear advantages depending on your budget, timeline, and priorities.
This guide compares them side by side so you can make an informed decision. We install both materials and will give you our honest recommendation based on what we see working on Long Island homes every day.

Cost Breakdown: What You Actually Pay on Long Island
Let us start with the number everyone wants to know. On a typical Long Island home (1,500-2,200 sq ft of roof area), here is what each option costs:
Asphalt shingle cost
- Budget (3-tab shingles): $6,000 - $12,000. We do not recommend 3-tab for Long Island due to lower wind ratings.
- Mid-range (architectural shingles): $8,000 - $18,000. This is the sweet spot for most homeowners. Brands like GAF Timberline, Owens Corning Duration, and CertainTeed Landmark fall in this range.
- Premium (designer shingles): $12,000 - $22,000. Thicker profiles, better warranties, enhanced aesthetics.

Metal roofing cost
- Metal shingles: $15,000 - $28,000. Individual metal pieces that install like shingles and look similar from the street.
- Standing seam: $18,000 - $35,000+. Vertical panels with raised, interlocking seams. The most durable and weather-tight metal option.
Metal costs 2-3 times more upfront. But the cost calculation changes when you factor in lifespan. Over 50 years, you would need two asphalt roofs ($16,000 - $36,000 total) versus one metal roof ($18,000 - $35,000). On a pure cost-per-year basis, metal can actually be cheaper.
Lifespan: How Long Each Roof Actually Lasts on Long Island
Manufacturer warranties are one thing. Real-world performance on Long Island is another. Here is what we actually see:
- Asphalt shingles: 20-25 years is typical on Long Island. Homes on the South Shore with direct coastal exposure tend to see the lower end. North Shore and inland homes can push 25-30 years with quality materials and good ventilation. The key factor beyond material quality is attic ventilation. Poor ventilation cooks shingles from below and cuts lifespan significantly.
- Metal roofing: 40-70 years. We have seen older metal roofs on Long Island still performing well after 40+ years. The material itself does not degrade from UV, freeze-thaw, or moisture the way asphalt does. The paint finish may fade over decades, but the structural integrity remains. The main maintenance item is checking fasteners and seams every 10-15 years.
Wind Performance: A Critical Factor for Long Island
Long Island gets serious wind. Nor'easters regularly produce sustained winds of 40-60 mph with gusts reaching 70-80 mph. Tropical storms and occasional hurricanes (Sandy in 2012, Ida remnants in 2021) can bring even higher winds.
Asphalt shingles are individual pieces nailed to the deck and sealed together by an adhesive strip activated by heat. When the seal breaks, whether from age, improper nailing, or extreme wind, individual shingles can lift and tear off. Premium architectural shingles are rated to 130-150 mph, and they perform well in most Long Island storms when properly installed. But they are inherently more vulnerable than a continuous surface.
Metal roofing uses panels that interlock at the seams (standing seam) or overlap with concealed fasteners (metal shingles). There are no individual tabs to catch wind. Standing seam systems are rated to 140-180 mph. After major storms on Long Island, we see significantly fewer service calls for metal roofs compared to shingle roofs.
Salt Air and Coastal Performance
If your home is within 2-3 miles of the coast, whether the South Shore, Fire Island, or the Long Island Sound, salt air is a factor in your roofing decision.
- Asphalt shingles: The shingle surface itself handles salt air fine. The issue is the metal components underneath: nails, flashing, drip edge, and vent boots. Standard galvanized steel corrodes in salt air within 5-10 years. Coastal installations need stainless steel or hot-dipped galvanized fasteners and aluminum flashing. For more on how different materials handle coastal conditions, see our roofing materials guide.
- Metal roofing: Aluminum and galvalume (aluminum-coated steel) panels resist salt corrosion well. Standard galvanized steel panels do not hold up near the coast. For coastal Long Island homes, we only install aluminum standing seam or galvalume panels with stainless steel fasteners. Properly specified, a metal roof on the South Shore outperforms asphalt in salt air resistance.
Ice Dams and Winter Performance
Ice dams are a real problem on Long Island during cold winters. They form when heat escaping through the attic melts snow on the upper roof, and the meltwater refreezes at the cold eaves, creating a dam that backs water under the shingles.
- Asphalt shingles: Vulnerable to ice dam damage. Water backed up behind an ice dam can work its way under shingle tabs and into the roof deck. Ice and water shield membrane at the eaves helps, but it is a backup, not a solution. The real fix is proper attic ventilation and insulation.
- Metal roofing: Metal's smooth surface sheds snow before it has a chance to melt and refreeze at the eaves. This significantly reduces ice dam formation. Snow guards can be installed to control how snow slides off to prevent sudden avalanches over doorways and walkways.
Energy Efficiency
Long Island summers are hot and humid. Attic temperatures can reach 140-160 degrees in July and August, which increases your cooling costs and stresses the roofing materials from below.
- Asphalt shingles: Dark-colored shingles absorb more heat. Lighter colors help, and some products have reflective granules that earn Energy Star ratings. But asphalt is inherently an absorptive material.
- Metal roofing: Reflects significantly more solar radiation than asphalt. Metal roofs with reflective coatings can reduce cooling costs by 10-25%. This is especially noticeable on homes without great attic insulation or on ranch-style homes where the living space is directly below the roof.
Appearance and Curb Appeal
This used to be a clear win for asphalt. Not anymore.
Asphalt shingles are available in dozens of colors and profiles. Architectural shingles create a dimensional, textured appearance that looks good on nearly any home style. They blend seamlessly into Long Island neighborhoods where asphalt is the standard.
Metal roofing has come a long way in aesthetics. Metal shingle products mimic the look of traditional shingles, slate, or wood shake. Standing seam has a clean, modern look that works well on contemporary and colonial homes alike. Color options are extensive, and the paint finish holds up far longer than the granule surface on asphalt.
Insurance Considerations
Some homeowners insurance companies offer premium discounts for impact-resistant and wind-resistant roofing. Metal roofs often qualify for these discounts because of their superior wind and impact ratings. The discount varies by carrier but can be 5-15% off your annual premium.
On the other hand, some insurance companies are increasing rates or dropping coverage for homes with asphalt shingle roofs older than 15-20 years. If your insurance situation is a factor, a metal roof can provide both performance and financial benefits.

Our Recommendation for Long Island Homeowners
After installing hundreds of roofs across Long Island, here is our honest take:
- Choose asphalt shingles if: Your budget is under $20,000, you plan to sell within 10-15 years, your home is inland with moderate weather exposure, or you want the most cost-effective roof replacement right now.
- Choose metal roofing if: You plan to stay in your home long-term (15+ years), you live near the coast where salt air is a factor, ice dams are a recurring issue, you want the best wind performance available, or you want to avoid ever replacing your roof again.
Both are excellent options when installed correctly. The wrong choice is skipping quality installation to save money, regardless of material. Ready to explore your options? Visit our roof replacement page for details on our process.
