Why Choose Aluminum Roofing vs. Other Materials
Aluminum roofing offers distinct advantages over traditional roofing materials such as asphalt shingles, steel, or wood. Homeowners and builders are increasingly choosing aluminum for its combination of longevity, strength, and sustainability. Key benefits include:
- Long Lifespan: Lasts 50+ years (up to 2–4× longer than asphalt shingles), meaning you may never need to re-roof again.
- Lightweight: About 70 lbs per 100 sq ft (extremely light): – much lighter than asphalt (~200–300 lbs) or tile (~900+ lbs). Its low weight puts less stress on your home’s structure.
- Corrosion Resistant: Aluminum naturally resists rust and corrosion, even in coastal salt-air climates. Unlike steel, it won’t rust over time, and it maintains its strength for decades without rotting.
- Weather & Fire Durable: Built to withstand extreme conditions – heavy storms, hail, and high winds. Aluminum roofs carry a Class IV hail impact rating (the highest in UL 2218 tests) and can withstand hurricane-level winds (120+ mph):contentReference. They’re also non-combustible, earning a Class A fire rating for maximum protection.
- Eco-Friendly: Often manufactured with high recycled content and 100% recyclable at end-of-life. Choosing aluminum helps keep roofing materials out of landfills and can contribute to energy savings through reflective coatings.
Cost: Aluminum roofing does have a higher upfront cost than asphalt (often a few times more), but it provides far greater long-term value. Thanks to its long lifespan and minimal upkeep, an aluminum roof can actually save money over decades compared to replacing asphalt roofs multiple times.

|---|---|---|---|---|
| Typical Lifespan | 50+ years | 15–25 years | 40–60 years | 20–30 years |
| Weight (per 100 sq ft) | ~50–75 lbs (very light) | ~250–300 lbs | ~100–150 lbs | ~300+ lbs (dry; heavier when wet) |
| Corrosion/Rot | Will not rust; ideal for coastal areas | Won’t rust, but shingles can decay or grow algae | Protected by coatings; can rust if coating fails | Prone to rot, mold, and insect damage |
| Fire Resistance | Class A (non-combustible) | Class A (fiberglass-based shingles) | Class A (non-combustible) | Low – wood is combustible (unless treated) |

Built for Tough Weather
Aluminum roofing is engineered to protect your property in the harshest conditions. These roofs hold up against Mother Nature’s worst:
- Hail: Impact-tested to the highest standard (UL 2218 Class IV), meaning it resists damage from hailstones. The tough aluminum surface won’t crack or puncture like some shingles do.
- High Winds: Interlocking panels and secure fasteners keep the roof anchored in extreme winds. Aluminum roofs are rated for hurricane-force gusts (120+ mph) and meet rigorous wind uplift codes in storm-prone regions.
- Fire: As a metal, aluminum is non-combustible and will not catch fire. An aluminum roof achieves a Class A fire rating (highest level), providing critical protection in wildfire zones and against wind-blown sparks.
- Corrosion & Snow: Unlike steel, aluminum won’t rust even in coastal salt air or heavy humidity. It sheds snow and ice easily, and its panels are built to withstand heavy snow loads without damage. Whether you face blazing sun, salt spray, or freeze-thaw cycles, aluminum roofing won’t deteriorate under extreme weather.
Total Ownership Value
An aluminum roof isn’t just a shelter – it’s an investment that pays off over time. While an asphalt roof might need to be replaced two or three times over 50 years, a quality aluminum roof will last that long with minimal upkeep. This means you avoid the recurring expense and hassle of re-roofing every couple of decades. Beyond longevity, aluminum roofs require little maintenance—no shingle replacements, no rot repairs, no frequent inspections. They maintain their appearance and performance year after year.
The savings extend further: aluminum roofs can improve energy efficiency by reflecting heat away, keeping your home cooler in summer (some coatings can reduce cooling costs by up to 25%). You may also benefit from lower insurance premiums, as metal roofing is highly fire- and impact-resistant. When it’s time to sell, the enduring quality of an aluminum roof is a strong selling point – prospective buyers value a roof that won’t need replacement soon, potentially boosting your property’s resale value. In short, the total cost of ownership for aluminum is often lower than that of cheaper roofing when you factor in longevity, energy savings, and maintenance costs over decades.
For Homes, Places of Worship, and Commercial Buildings
We understand that different buildings have different priorities. Our aluminum roofing solutions address the unique needs of residential homes, churches and historic buildings, and commercial properties:
Residential Homes
For homeowners, aluminum roofing provides peace of mind and lasting beauty. No more curling shingles, mold streaks, or surprise leaks – your home stays protected in all weather. With a wide range of styles and colors, you can enhance your curb appeal and match any architectural design, from modern to traditional. Plus, aluminum’s energy efficiency helps keep indoor temperatures comfortable, potentially lowering your cooling bills in the summer.
Places of Worship & Historic Buildings
Churches, heritage buildings, and other places of worship often feature steep pitches and classic designs that demand a premium look. Aluminum roofing allows these buildings to preserve their historic or sacred appearance (whether it’s the look of slate, cedar, or tile) while significantly improving durability. The lightweight nature of aluminum is especially beneficial for older structures – it can often replace a heavy old roof (like slate or clay tile) without requiring structural reinforcement. And with a lifespan measured in decades, an aluminum roof ensures the congregation or organization won’t need to budget for another new roof for generations. It’s a respectful way to maintain tradition and integrity while providing modern protection.
Commercial Buildings
Businesses and commercial properties choose aluminum roofing for its long-term cost savings and reliability. Whether it’s an office, a retail plaza, or a community center, an aluminum roof means fewer disruptions – you won’t be dealing with leaks or having to shut down for re-roofing every 15 years. The fire-resistant and high-wind ratings of aluminum roofing can help commercial buildings meet strict building codes and safety requirements, especially for schools, hotels, or facilities where safety is paramount. Additionally, the sleek look of options like standing seam provides a professional, modern image. Over the life of the building, the reduced maintenance and potential energy savings (thanks to reflective metal surfaces) make aluminum roofing a smart business decision as much as an aesthetic one.

Frequently Asked Questions
How long does an aluminum roof last?
A properly installed aluminum roof can easily last 50 years or more. In fact, many aluminum roofing systems come with 50-year or even lifetime warranties. This is significantly longer than the lifespan of a typical asphalt shingle roof (which lasts around 15–20 years on average). With minimal maintenance, an aluminum roof will provide reliable protection for decades – most homeowners will never need to replace it in their lifetime.
How much does an aluminum roof cost compared to shingles?
Aluminum roofing generally costs more upfront than asphalt shingles – often about 2 to 3 times the price per square foot. For example, if asphalt shingles cost $4 per sq. ft., an aluminum roof might cost $10–$12 per sq. ft. installed (exact pricing depends on the profile and your location). While the initial investment is higher, it’s essential to consider the long-term value: you get a roof that lasts much longer and requires far less upkeep. Over 30–50 years, an aluminum roof often costs less overall than replacing multiple shingle roofs.
Are aluminum roofs noisy when it rains?
Can an aluminum roof be installed over my existing shingles?
In many cases, yes. Aluminum roofing is very lightweight, which often allows it to be installed over a single layer of existing asphalt shingles. This method (called a retrofit installation) can save you the time, cost, and mess of a full tear-off. However, your roofing contractor will need to inspect the existing roof to ensure the decking and shingles are in good condition, and local building codes must allow it. If the old roof is too deteriorated or if two layers are already present, a tear-off may be required. Always consult with a professional roofer to determine the best approach for your home.
Will an aluminum roof rust or corrode over time?
No – aluminum by its nature will not rust. Rust is the corrosion of iron or steel, and since aluminum contains no iron, it can’t form rust (the reddish oxide). Aluminum does oxidize, but the oxidation forms a thin protective layer of aluminum oxide that shields the metal underneath from further corrosion. This is why aluminum is ideal for coastal and humid climates; it withstands salt spray and moisture without corroding. Additionally, our aluminum roofing panels are finished with high-performance coatings that further prevent any degradation. The result is a roof that stays corrosion-free and looking great for its entire lifespan.
