Metal vs. Slate Roofing: Which is Right for Your Long Island Home?
When it comes to investing in a new roof for your Long Island home, choosing the right material can feel overwhelming. Among the most sought-after options are metal roofing and slate roofing, two premium materials known for their longevity, aesthetics, and resilience.
At Bonac Builders, we’ve worked with both extensively across East End communities like Southampton, Quogue, East Hampton, and beyond. In this guide, we’ll break down the pros and cons of each material to help you decide whether a metal or slate roof is the best fit for your home.
Style & Curb Appeal
Metal Roofing:
Modern, clean, and available in a variety of colors and finishes, including standing seam, matte black, and copper. Metal roofs are a great choice for contemporary and coastal homes. They offer a bold aesthetic that pairs well with modern architecture and eco-friendly home designs.
Slate Roofing:
If you love timeless charm, a slate roof delivers. Often seen on historic estates and traditional Hamptons homes, slate shingles offer natural texture and a high-end look that can elevate any classic build. They’re perfect for cedar-shingle-sided homes or stone facades.
Durability & Lifespan
Slate roofing is virtually unmatched in longevity, often lasting 80–100 years or more when properly installed. However, it is heavier and requires structural support.
Metal roofing, while not quite as long-lasting as slate, still delivers 40–70 years of protection. It's a favorite among homeowners looking for durability without the weight of stone.
Both materials perform well in the weather conditions of Long Island, handling salt air, wind, heavy rain, and snow with ease.
Energy Efficiency & Environmental Impact
Metal roofing reflects heat, making it a fantastic choice for energy savings during the warmer months. Many homeowners see a noticeable drop in cooling bills after installation. It’s also 100% recyclable and considered one of the most sustainable roofing materials on the market.
Slate roofing, being a natural stone product, is inherently eco-friendly and provides natural insulation. It helps regulate indoor temperatures and offers excellent thermal performance.
Maintenance & Repairs
Metal roof maintenance is relatively low. It resists mildew, rot, and pests, and most issues can be addressed quickly by a qualified roof repair contractor.
Slate roof maintenance is minimal as well, but repairs must be handled by a roofer familiar with slate. Cracks or breaks require skilled labor, often more costly than metal roof repairs.
Cost Comparison
Slate roofing is typically more expensive upfront due to the cost of materials and the specialized labor needed for installation. Metal roofing is still a premium option but often comes in at a more budget-friendly price point.

Home Value & ROI
Both options increase curb appeal and raise the market value of your home. A metal roof replacement often returns between 60–70% of the project cost in resale value. Slate can offer even more value in luxury markets like the Hamptons, where buyers look for distinctive, long-lasting materials.
For custom homes, Bonac Builders frequently incorporates custom metal flashing or copper details to blend both aesthetics, giving homeowners the best of both worlds.
