Roof Material Overview

Asphalt Shingles

Asphalt shingles have long been America’s most popular roofing option. They are made from fiberglass or organic mats saturated in asphalt and topped with mineral granules. Their popularity stems from affordability, ease of installation, and a wide range of colors and styles. Asphalt roofs suit most architectural designs, making them a versatile choice.

Metal Roofing

Metal roofs are gaining traction due to their longevity and modern aesthetics. These roofs include options such as steel, aluminum, copper, and zinc. Metal panels or shingles are installed with interlocking seams or fasteners, offering enhanced weather resistance. Metal roofing is available in an array of colors, profiles, and finishes.

Initial Installation Cost

Asphalt Roof Cost

Asphalt shingles are the least expensive roofing option in the U.S. Installation costs average between $3.50 and $6.50 per square foot. For a standard 2,000-square-foot roof, total expenses often range from $7,000 to $13,000, depending on region, roof complexity, and shingle grade.

Metal Roof Cost

Metal roofing requires a higher upfront investment. Installation costs typically fall between $7 and $14 per square foot. This means a 2,000-square-foot roof can cost $14,000 to $28,000 or more. Longevity and reduced maintenance often justify this expense over time, as explored in upcoming sections.

Lifespan And Durability

Asphalt Longevity

Most asphalt shingles last 15 to 30 years, with premium “architectural” shingles edging closer to 30. Lifespan depends on quality, weather exposure, and proper installation. High heat, severe storms, and rapid temperature changes can reduce shingle longevity.

Metal Longevity

Metal roofs can last 40 to 70 years or more, with some copper and zinc options exceeding a century. Metal’s resistance to rot, insects, and impact damage surpasses that of asphalt. Homeowners choosing metal can often install once and avoid future replacement costs.

Maintenance Requirements

Asphalt Maintenance

Asphalt shingles require moderate ongoing maintenance. Periodic inspections are necessary to spot broken, curled, or missing shingles. Granule loss and algae growth need attention. Repairs and replacement of aging or storm-damaged shingles are common tasks.

Metal Maintenance

Metal roofing is low-maintenance in comparison. Maintenance usually includes occasional cleaning to remove debris and checking seams or fasteners for tightness. While paint finishes can fade or peel over decades, most problems are cosmetic and easy to address.

Weather And Fire Resistance

Weather Resistance Of Asphalt

Asphalt shingles perform well in a variety of climates but are susceptible to wind and hail damage. High winds can lift or blow off shingles, while hail, especially golf-ball-sized or larger, may crack them. Advanced “impact-resistant” products improve performance but add cost.

Weather Resistance Of Metal

Metal roofs excel in all weather conditions. Panels interlock tightly, making them virtually impervious to wind, even up to 140 miles per hour. Metal sheds snow and ice effectively, resists hail dents, and will not rot. This makes metal an ideal choice in hurricane, tornado, or wildfire-prone areas.

Fire Resistance Considerations

Metal roofs are inherently noncombustible and carry Class A fire ratings, the highest available. Asphalt shingles can also achieve a Class A rating, but only when installed with accompanying fire-resistant underlayments.

Energy Efficiency And Environmental Impact

Asphalt Roofing Efficiency

Asphalt shingles absorb sunlight, which can heat interiors unless reflective “cool roof” shingle options are used. Attic insulation and venting help mitigate heat gain. Traditional asphalt is less eco-friendly, with petroleum-based content and limited recyclability.

Metal Roofing Efficiency

Metal roofs naturally reflect solar radiation, reducing cooling loads by up to 25%. Many metal products have special “cool roof” coatings for enhanced performance. Most metal roofing is made from recycled material and is 100% recyclable at end of life, reducing landfill waste.

Curb Appeal And Style Options

Design Choices With Asphalt

Modern asphalt shingles offer strong curb appeal with classic looks suited to most U.S. neighborhoods. They mimic slate, wood, and even tile at a fraction of the cost. Color diversity is vast, but fade is a concern over time.

Design Choices With Metal

Metal roofing has evolved with a range of profiles, from standing seam panels to shingles mimicking clay, slate, or shake. It’s available in glossy, matte, or textured finishes across vibrant and neutral palettes. For contemporary homes, metal offers striking architectural interest.

Installation Complexity And Timing

Asphalt Installation

Asphalt shingles are fast and straightforward to install by any licensed roofing contractor. Most residential jobs complete within one to three days. If old shingles need removal, labor may increase slightly.

Metal Installation

Metal installation requires specialized skills and more time due to panel interlocking or hidden fasteners. Installation can take three to ten days, depending on roof size and complexity. Skilled installers ensure watertight seams and proper flashing for optimal longevity.

Cost Over The Roof’s Lifetime

Long-Term Cost Analysis For Asphalt

Lower upfront cost but higher long-term costs come with asphalt shingles. Most homeowners will need at least one replacement over a 40-50 year span. Ongoing repairs and routine maintenance add to the total expense. Insurance premiums are typically moderate.

Long-Term Cost Analysis For Metal

Metal roofs cost more initially but pay off with fewer replacements and repairs. Maintenance is minimal, insurance premiums may decrease due to fire/weather resistance, and higher resale value is possible. For those staying long-term, metal is often more affordable over the decades.

Environmental Impact

Asphalt Roofing And Sustainability

Asphalt shingles pose environmental challenges due to moderate recyclability and petroleum content. Old shingles often end up in landfills; however, some are repurposed for paving material in certain communities.

Metal Roofing And Sustainability

Metal roofing is one of the most sustainable options available. It commonly includes post-consumer recycled content and is itself fully recyclable at end of life. The long service span means fewer raw materials are needed over time.

Insurance, Incentives, And Home Resale Value

Insurance Considerations

Insurance premiums can be lower for metal roofs due to superior resistance to disaster and fire. Some insurers offer specific discounts for metal installations, particularly in high-risk areas.

Tax Credits And Incentives

Homeowners may qualify for federal or local incentives for energy-efficient metal roofing. Asphalt products, unless reflective or designated “cool roof,” typically do not qualify. Always check with local building authorities for current programs.

Impact On Home Value

Both roofing choices increase curb appeal and marketability. Metal may yield a higher resale return in markets where longevity and low maintenance are prized, while asphalt remains universally accepted.

Climate And Regional Suitability

Best Roof For Snow, Rain, And Ice

Metal is optimal for heavy snow, ice, and rain regions, thanks to its slick surface and strength. It sheds precipitation rapidly and resists freeze-thaw damage. Asphalt can perform well with proper attic insulation and ventilation, but ice dams and water intrusion are greater risks.

Best Roof For Hot Climates

Metal’s reflective surface makes it ideal for hot, sunny climates, reducing attic heat and cooling bills. Special coatings further boost performance. Asphalt absorbs heat more readily, but “cool” shingles help mitigate this effect in some products.

High-Wind And Storm Areas

Both materials can be rated for high wind, but metal performs exceptionally in hurricane-prone zones and wildfires. Proper installation is vital for both to maintain wind and rain resistance.

Noise, Comfort, And Insulation Factors

Noise Concerns

Metal roofs can be louder during rain or hail than asphalt. Proper insulation and attic design virtually eliminate this difference, making both options quiet and comfortable indoors.

Insulation And Comfort

Both systems require adequate underlayment, attic insulation, and proper attic ventilation. Either can maintain comfortable, energy-efficient interiors with correct design and installation.

Common Myths And Misconceptions

• Myth: Metal roofs attract lightning. In reality, metal neither increases nor decreases the likelihood of a strike, but it safely dissipates the charge if struck.
• Myth: Asphalt roofs are waterproof. Shingles themselves are water-shedding, not fully waterproof. Proper underlayment and installation are required for water tightness.
• Myth: Metal roofs cause higher home temperatures in summer. Reflective coatings improve energy efficiency, often keeping attics cooler than asphalt.
