Install Metal Shingle Roofs

Can you get a roof that looks like premium architectural shingles but performs like metal? Last fall we replaced an aging asphalt roof on a colonial in Garden City with a dimensional metal shingle system. Three neighbors stopped by before the install was even finished because they assumed it was just really high-end shingles. When the homeowner told them it was actually metal, they couldn’t believe it. That’s the sweet spot metal shingles occupy: the familiar curb appeal of a traditional shingle roof with the durability, wind resistance, and longevity of a metal system. For Nassau County homeowners who want to upgrade their roof protection without making their house look dramatically different, metal shingles offer a practical middle ground that works with almost any neighborhood aesthetic.

After two decades installing roofs in Nassau County-first asphalt shingles on hundreds of homes, now specializing in metal shingle installs-I’ve watched this material category grow from a niche specialty product to a serious consideration for homeowners who are tired of replacing their roof every 15 years. Metal shingles cost more up front than asphalt, but they typically last 40 to 60 years, resist storm damage better, and can actually increase home value in a market where buyers recognize the difference between a basic roof and a premium installation. This guide walks through what metal shingle roofs are, how they compare to asphalt and other metal systems, what installation involves, and what you should discuss with a local roofer before committing to the upgrade.

What Is a Metal Shingle Roof?

A metal shingle roof is made from individual or grouped steel or aluminum panels that are stamped, formed, or coated to mimic the look of traditional roofing materials-usually architectural asphalt shingles, slate, wood shake, or tile. Unlike standing seam metal roofs that run in long vertical panels, metal shingles are smaller units that interlock on all four sides and fasten to the roof deck in a staggered, overlapping pattern just like asphalt shingles. The difference is that each “shingle” is made from corrosion-resistant metal with a baked-on finish designed to handle decades of sun, rain, wind, and salt air.

How Metal Shingles Are Made

Most metal shingles start as galvanized steel or aluminum sheet stock, which is then roll-formed or stamped into a profile that creates dimension and shadow lines. The metal surface gets multiple coatings: a primer layer, a color coat (usually a high-performance paint system or stone-coated acrylic), and often a clear topcoat for UV resistance and dirt shedding. Some premium products add a granulated mineral surface-literally crushed stone embedded in an acrylic layer-that makes them look and feel almost identical to heavy asphalt shingles from the ground. The panels interlock with hidden clips or overlapping edges and are fastened with screws or nails placed at specific points that usually get covered by the next course, keeping the roofline clean and the fasteners protected from weather.

Common Metal Shingle Styles

• Architectural shingle look-alikes: Dimensional profiles with multiple tabs per panel that replicate the layered, textured appearance of high-end asphalt shingles.
• Slate-look panels: Crisp rectangular or diamond-shaped units with sharp edges and deep shadow lines that mimic natural slate without the weight or fragility.
• Wood shake-style metal shingles: Formed with irregular grain patterns and staggered edges for a rustic or coastal cedar shake appearance, popular in waterfront areas of Nassau County.
• Stone-coated metal shingles: Steel panels covered with an acrylic-bonded stone layer that closely replicates heavyweight asphalt, concrete tile, or even clay tile profiles.

The variety means you can usually find a metal shingle that fits your home’s architectural style and blends with your neighborhood, whether you’re in a community of traditional capes in Levittown or larger colonials in Rockville Centre.

Metal Shingles vs Asphalt Shingles vs Other Metal Roofs

Performance Compared to Asphalt

Metal shingles are non-combustible, resist rot and insect damage, and handle wind, hail, and debris impact better than asphalt. I’ve seen asphalt roofs in Massapequa lose entire sections during nor’easters because wind gets under a few loose shingles and peels back whole strips. Metal shingles interlock and are mechanically fastened in a pattern that resists uplift even in sustained 80-mph gusts. They also shed water faster because the smooth metal surface doesn’t absorb moisture or grow algae like asphalt granules do over time. In Nassau County storms-where we get wind-driven rain from multiple directions-that faster drainage and better fastening pattern mean fewer patchwork repairs and less risk of interior leaks after big weather events.

Metal Shingles vs Standing Seam

Standing seam metal roofs offer a very modern, clean look with continuous vertical panels and raised seams running from ridge to eave. Some homeowners love that aesthetic. Others feel it looks too industrial or doesn’t fit their colonial, cape, or tudor home. Metal shingles keep a more traditional appearance that neighbors and HOAs usually accept without question. They’re also easier to detail around complex rooflines with multiple hips, valleys, dormers, and roof planes because you’re working with smaller units that can adapt to direction changes. Standing seam requires careful planning on complicated roofs and can look odd if you have a lot of interruptions. Both systems offer strong performance when installed properly-the choice often comes down to aesthetics, architectural fit, and sometimes HOA rules.

Cost and Long-Term Value

Metal shingles generally cost more upfront than quality architectural asphalt shingles. A typical asphalt roof replacement in Nassau County runs $8,000 to $15,000 depending on size and complexity. A metal shingle roof on the same house typically costs $16,000 to $28,000, sometimes more for premium profiles or difficult layouts. That’s roughly double the cost of asphalt, but you’re also getting a roof that can last 40 to 60 years compared to 18 to 25 years for asphalt. Over the long term, you may only install one metal roof in your ownership compared to two or even three asphalt roofs. Factor in fewer repairs, better storm performance, and potential energy savings from reflective finishes, and the total cost of ownership often favors metal shingles-especially if you plan to stay in your home for many years or want to market a premium roof when you sell.

Where Metal Shingle Roofs Make the Most Sense

Roof Style and Complexity

Metal shingles work very well on roofs with hips, valleys, dormers, and multiple roof planes where smaller interlocking units can adapt more easily than long straight panels. I’ve installed metal shingles on complex colonials in Merrick with six different roof planes, multiple chimneys, and several dormers. The shingle format made it straightforward to transition between sections and maintain proper water flow in all the valleys. Standing seam metal would have required custom pans and more complicated flashing details. Metal shingles are also typically used on slopes similar to asphalt shingles-usually 3:12 pitch or steeper-so they’re a natural fit for most Nassau County homes with pitched roofs. If you have a very low slope, standing seam or a membrane system might be a better choice.

Home Style and Neighborhood Expectations

Colonial, cape, split-level, ranch, and tudor homes all look natural with shingle-style metal roofs because the profiles preserve a familiar residential streetscape. On a street in Wantagh full of 1960s ranch homes, we installed a slate-look metal shingle roof that blended perfectly with the neighborhood while quietly upgrading the homeowner’s protection and eliminating the need for another roof replacement. In areas where a big visual change might draw pushback-either from neighbors or from an HOA-metal shingles can be a quieter upgrade than going to a bold standing seam profile. You still get metal performance, but you don’t change the character of your home or your block.

HOA and Local Rules

Before committing to any metal roof, check your HOA covenants or village guidelines about roof materials and appearance. Many HOAs that restrict “metal roofs” will approve metal shingles once they see product photos and realize they look like upscale architectural shingles or slate, not corrugated barn metal. I’ve worked with homeowners in several Nassau County communities where the HOA initially said no to metal, then approved the project once we submitted samples and installation photos from similar homes. If you’re in a deed-restricted community, bring product literature and photos to your architectural review board early in the process so you don’t waste time planning a roof you can’t actually install.

Overview of Metal Shingle Roof Installation

1. Roof Assessment and Product Selection

A good contractor starts by inspecting your existing roof deck, flashings, and attic ventilation to identify any structural issues, water damage, or ventilation problems that need to be addressed before the new roof goes on. We measure the roof, note all the penetrations (chimneys, vents, skylights), and evaluate how complex the layout is. Then we recommend specific metal shingle products that suit your slope, exposure, budget, and aesthetic goals. You’ll choose a style (architectural, slate, shake), a substrate (steel or aluminum), and a color that complements your siding and trim. Most manufacturers offer 10 to 20 standard colors plus custom options if you need a specific match.

2. Tear-Off vs Install Over Existing Shingles

Best practice usually involves tearing off your old asphalt shingles so we can inspect the roof deck, replace any damaged or rotted plywood, and ensure a clean, flat substrate for the metal shingles. If there are existing leak issues, multiple shingle layers, or any signs of trapped moisture, tear-off is mandatory. In some cases-if you have a single layer of sound asphalt shingles and the manufacturer allows it-you can install metal shingles over the existing roof. This saves disposal cost and time, but you lose the opportunity to inspect and repair hidden problems. I always recommend tear-off on Nassau County homes because the salt air, storm exposure, and age of many roofs here mean there’s often hidden damage that you don’t want to trap under a new 50-year roof.

3. Underlayment, Ice Barrier, and Ventilation

Once the deck is clean and repaired, we install synthetic underlayment across the entire roof as a secondary water barrier. At the eaves, in valleys, and around chimneys and skylights, we add ice-and-water shield-a self-sealing membrane that protects against wind-driven rain and ice dams. Ice dams aren’t as severe in Nassau County as they are further upstate, but we still get them during certain winter storms, and ice-and-water shield is cheap insurance. We also check and adjust attic ventilation, adding or upgrading ridge vents, soffit vents, or gable vents as needed so the new roof works with proper airflow. Good ventilation helps with both summer cooling and winter condensation control, and it’s a critical part of any long-lasting roof system.

4. Installing Metal Shingles

Installation starts with starter strips at the eaves to provide a secure attachment point and proper drip edge alignment. Then we begin laying interlocking metal shingle panels in staggered courses up the roof, following the manufacturer’s layout pattern to maintain proper alignment and water flow. Each panel locks into the one below and beside it, and fasteners (screws or nails) are placed at designated points-usually hidden by the overlapping shingles-so you get a clean look and strong wind resistance. Valleys get either woven metal shingles or dedicated valley panels depending on the system. The process looks a lot like installing asphalt shingles but requires more attention to alignment and fastener placement because metal is less forgiving than asphalt if you get off-course.

5. Flashing, Ridge, and Trim Work

Once the main roof surface is complete, we install or upgrade all the trim and flashing components: new step flashing at wall intersections, custom chimney flashings, ridge caps, hip caps, drip edge at eaves and rakes, and transition flashings around skylights and roof penetrations. Metal shingles need careful flashing integration because water moves faster on metal than on asphalt, so any gaps or poorly sealed transitions can cause leaks. We also pay close attention to valleys-where two roof planes meet and water converges-because those are high-flow areas that need robust flashing and proper overlap. The final result should be a seamless-looking roof where all the metal components work together to shed water efficiently and resist wind uplift at every edge.

Metal Shingle Roofs in Nassau County’s Climate

Handling Nor’easters and Wind-Driven Rain

Interlocking metal shingles and secure fastening patterns help resist lifting and water intrusion from sideways rain better than loose or aging asphalt shingles. During a nor’easter, wind doesn’t just blow straight down on your roof-it comes from different directions, changes speed, and creates uplift pressure at roof edges and peaks. Metal shingles are mechanically fastened at multiple points per panel and interlock on all sides, so they resist that uplift pressure much more effectively than individual asphalt shingles that rely on adhesive strips that weaken over time. Edge detailing-at eaves, rakes, and ridges-is engineered to meet local wind codes and is a key focus during installation. A properly installed metal shingle roof should handle anything Nassau County weather throws at it without losing panels or allowing water penetration.

Salt Air and Corrosion Resistance

Homes closer to the bay or ocean face more aggressive corrosion from salt-laden air. Aluminum metal shingles or Galvalume-based steel shingles with robust coatings, plus stainless steel or ceramic-coated fasteners, handle that exposure better than standard galvanized steel. I’ve worked on homes in Long Beach and Island Park where we specifically chose aluminum or stone-coated steel with upgraded fasteners because the salt air accelerates corrosion on any exposed metal. Further inland-in towns like East Meadow or Hicksville-coated steel shingles perform very well if cut edges, flashings, and fasteners are detailed correctly and the finish stays intact. The key is matching the product and installation details to your specific exposure level so the roof lasts its full design life without premature rust or coating failure.

Heat, Sun, and Reflective Finishes

Many metal shingles come with reflective finishes or “cool roof” colors that reduce heat absorption compared with dark asphalt shingles, helping lower attic and interior temperatures on summer days. Metal roofs can also re-radiate absorbed heat faster than asphalt once the sun sets, so attic temperatures drop more quickly in the evening. Real comfort gains depend on insulation and ventilation as much as roof color-if your attic is poorly insulated or badly ventilated, a reflective roof won’t fix that by itself. But if you combine a light-colored or reflective metal shingle roof with proper attic insulation and ventilation, you can reduce cooling costs and extend the life of your HVAC equipment by keeping your attic cooler during July and August.

Maintenance Expectations for a Metal Shingle Roof

Routine Visual Checks

Metal shingle roofs need less maintenance than asphalt, but they’re not maintenance-free. I recommend periodic visual inspections from the ground or by drone photo after major storms to look for displaced shingles, damaged flashings, or tree-limb impact areas. Keep gutters clean so water and debris don’t back up at the eaves. Trim tree branches that hang over the roof to reduce debris accumulation, prevent scratching, and minimize the chance of a falling limb punching through during a storm. If you notice any loose or damaged panels, call a roofer to reattach or replace them before water gets underneath and causes bigger problems.

Professional Inspections Over Time

Have a roofer inspect your metal shingle roof every 3 to 5 years to check fasteners, flashings, sealant condition, and finish wear-especially if you’re near the coast or if the roof is 20+ years old. Catching small issues early (sealant wear around chimneys, minor coating chips from hail, a few loose fasteners) helps maintain both performance and appearance for decades. Metal roofs can last 40 to 60 years, but that lifespan assumes you catch and fix little problems before they turn into big leaks or structural damage. The good news is that maintenance visits are usually quick and inexpensive compared to the ongoing repairs and partial replacements that asphalt roofs often need as they age.

Questions to Ask a Nassau County Roofer About Metal Shingle Installation

Product and Design Questions

• Which metal shingle brand and profile do you recommend for my home, and is it steel or aluminum?
• What wind and impact ratings does this product have, and is it approved for our local code and exposure?
• How will the new roof work with my existing ventilation and insulation setup?
• What colors are available, and can I see samples on a house similar to mine?
• How does this system handle ice dams, and what underlayment will you use at the eaves and valleys?

Installation and Warranty Questions

• Will you remove my existing roofing, and how will you handle any damaged decking you find?
• What manufacturer and workmanship warranties come with this metal shingle roof, and what exactly do they cover?
• Can you show examples or references for other metal shingle installations you’ve completed in Nassau County?
• How long will the installation take, and what happens if we get rain during the project?
• What’s included in your estimate (tear-off, disposal, new flashings, ridge vents, cleanup)?

Frequently Asked Questions About Metal Shingle Roofs

Are metal shingles noisy when it rains?

Over solid decking with proper underlayment and attic insulation, noise is usually comparable to asphalt shingles. The “loud metal roof” reputation comes mostly from metal installed over open framing with no insulation-like old barn roofs or porch covers. On a typical Nassau County home with plywood or OSB sheathing, synthetic underlayment, and attic insulation, most homeowners report no noticeable increase in rain noise compared to their old asphalt roof. Some even say the sound is softer because the metal shingles are textured and the stone-coated versions have a granulated surface that dampens impact noise.

Will a metal shingle roof make my home hotter?

With reflective finishes, good ventilation, and proper insulation, metal roofs often reduce heat gain compared with dark asphalt shingles. Any increase or decrease in indoor temperature is about the whole roof-attic-insulation system, not just the metal surface. If you choose a light color or a “cool roof” rated finish and make sure your attic has adequate ventilation and insulation, a metal shingle roof can actually keep your home cooler than an old dark asphalt roof. The metal surface also cools down faster after sunset, which helps reduce overnight attic temperatures during summer heat waves.

Can you walk on a metal shingle roof?

Professionals can walk on metal shingle roofs using proper techniques, clean soft-soled shoes, and by stepping on the lower, flatter parts of each panel where they’re supported by the deck underneath. Homeowners should avoid unnecessary foot traffic to prevent denting, scratching the finish, or accidentally loosening fasteners. If you need to access the roof for maintenance or to clean gutters, have a roofer do it or at least show you the safest path and techniques. Metal shingles are durable but they’re not indestructible-concentrated weight on an unsupported section can dent the metal and compromise the finish, which can lead to corrosion down the road.

Can a metal shingle roof be installed over my old shingles?

It’s sometimes allowed over a single, sound layer of asphalt shingles if the manufacturer approves it and local code permits it. But tear-off is often the more thorough and future-proof approach because it lets us inspect the deck, replace damaged wood, and ensure proper ventilation and underlayment. Installing over old shingles saves disposal cost but traps any existing problems underneath a new 50-year roof. I usually recommend tear-off, especially in Nassau County where salt air, moisture, and age mean there’s often hidden damage that you don’t want to discover 10 years into your new roof.

Do you install metal shingle roofs throughout Nassau County?

Yes. Metal shingle installation services are available across Nassau County-from coastal communities like Long Beach and Island Park to inland towns like Levittown, Hicksville, Massapequa, Garden City, and Rockville Centre. Every neighborhood and house style has specific considerations, and matching the right metal shingle product and installation details to your home’s exposure, architecture, and HOA rules is what makes the difference between a good roof and a great one.

Upgrade to Metal Shingles with Confidence

Metal shingle roofs offer a strong blend of traditional curb appeal and metal-level performance, making them well-suited to many Nassau County homes where homeowners want better protection without changing the character of their house or neighborhood. Success comes from choosing the right product for your exposure and style, making sure it meets any HOA requirements, and having it installed by a roofer who understands both metal roofing systems and the specific challenges of Long Island weather.

Collect photos of your current roof from all sides, note any recurring problems (leaks, ice dams, wind damage), and review your HOA rules if applicable. Then meet with a local contractor experienced with metal shingles to design a solution tailored to your property. Use the questions and comparisons from this guide as a checklist so your final choice feels informed and aligned with both your budget and your long-term goals. A well-chosen and properly installed metal shingle roof can protect your home for 40 to 60 years with minimal maintenance-making it one of the last roofs you’ll ever need to buy.
