Metal Roofing vs. Asphalt Shingles: Which Is Best for Your Home?
A clear, side-by-side comparison to help St. Louis homeowners and property managers choose the right roofing system for their budget, climate, and long-term goals.
Choosing between metal roofing and asphalt shingles is one of the biggest decisions a homeowner will make. Both systems can protect a home for decades, but they differ significantly in cost, durability, and performance against St. Louis’s mix of summer heat, hailstorms, and winter freeze-thaw cycles. Here’s how the two compare, category by category.
Longevity Comparison
Asphalt shingles typically last 15 to 30 years, depending on the quality of the shingle and how well the roof is ventilated and maintained. Standard three-tab shingles fall on the shorter end, while architectural (dimensional) shingles can approach 30 years with proper care.
Metal roofing lasts significantly longer, with a lifespan of 40 to 70 years depending on the material and coating. Steel, aluminum, and copper panels resist the granule loss, curling, and cracking that eventually retire an asphalt roof. For homeowners planning to stay in a property long-term, metal often means installing a roof only once.
Wind and Hail Resistance
Metal Roofing
Standing seam and steel panel systems are rated to withstand winds of 140 mph or higher and hold up well against hail, especially thicker gauge panels. Impact-resistant metal roofing can carry a Class 4 rating, the highest available.
Asphalt Shingles
Quality architectural shingles with proper nailing can resist winds up to 130 mph and are available in Class 4 impact-resistant versions. Standard shingles are more prone to granule loss and bruising from hail, which can shorten lifespan even without a visible leak.
In St. Louis, where severe thunderstorms and hail are common, both systems perform best when installed correctly and paired with impact-resistant ratings where available.
Energy Efficiency Considerations
Metal roofing reflects more solar radiant heat than asphalt, which can lower cooling costs during hot Midwest summers, particularly with a cool-roof coating or light color finish. Metal also sheds heat quickly once the sun sets, reducing heat retention overnight.
Asphalt shingles absorb more heat, which can raise attic and interior temperatures in the summer. Proper attic insulation and ventilation narrow this gap, but metal generally holds an edge in energy performance, especially on homes with large roof surfaces.
Upfront Cost vs. Lifecycle Cost
| Factor | Asphalt Shingles | Metal Roofing |
|---|---|---|
| Typical installed cost | Lower upfront | 2 to 3 times higher upfront |
| Expected lifespan | 15 to 30 years | 40 to 70 years |
| Replacements over 50 years | Likely 2 or more | Often 0 to 1 |
| Long-term cost per year | Can be higher over time | Often lower over time |
Maintenance Differences
Asphalt roofs need periodic inspections for granule loss, cracked or curling shingles, and moss or algae growth, along with occasional shingle replacement after storms. Gutters should be checked regularly since shingle granules can accumulate and cause clogs.
Metal roofs require comparatively little maintenance: mainly checking fasteners and sealants on exposed-fastener systems and clearing debris. Standing seam systems, which use no exposed fasteners, need even less upkeep over the life of the roof.
Noise Myths About Metal Roofs
A common concern is that metal roofs are noisy in the rain. In practice, modern metal roofing is installed over solid decking with an underlayment, and often insulation, between the panels and the living space. This construction absorbs sound the same way it does under an asphalt roof. Most homeowners report no noticeable difference in rain or hail noise once the roof is properly installed.
Insurance Benefits
Many insurance carriers offer premium discounts for impact-resistant roofing, including Class 4 metal systems, since they reduce the likelihood of hail damage claims. Some insurers also view metal’s wind resistance favorably in areas prone to severe storms. Homeowners should ask their carrier directly, as discounts vary by insurer and region.
Exposed Fastener vs. Standing Seam Systems
Exposed Fastener Panels
Screws are visible on the panel face, and the system is more affordable and faster to install. Fasteners and their rubber washers need periodic inspection since they can loosen or wear over time.
Standing Seam Panels
Panels interlock with hidden fasteners, giving a cleaner look and eliminating exposed points where leaks can develop. It costs more upfront but generally lasts longer with less maintenance.
Best Applications for Each System
Asphalt shingles work well for homeowners prioritizing lower upfront cost, standard residential aesthetics, and a roof style that fits most neighborhood guidelines and resale expectations.
Metal roofing is a strong fit for homeowners planning to stay long-term, properties in storm-prone areas, energy-conscious households, and commercial or steep-slope applications where durability and low maintenance matter most.
