If you’re considering re-roofing, your choice of materials will directly impact the longevity of your new roof. While the most durable roofing materials can be more expensive, their extended lifespan and durability often justify the investment. Keep reading to learn more about popular roofing materials and how long they typically last when installed by a professional roofing company.
Common Roofing Materials and Their Lifespans
According to the NAHB, most roofing products are designed to last at least several decades under normal weather conditions. Here’s an overview of the expected longevity for various roofing materials:
Asphalt Shingles
- Lifespan: 15-30 years
- Details: Asphalt shingles are the most popular roofing material in North America due to their affordability and ease of installation. They come in three main types:
- 3-Tab Shingles: Flat, with a uniform shape and size, these are the most basic type.
- Architectural Shingles: Thicker and more durable, offering a more dimensional and layered look.
- Premium Shingles: High-end options that can mimic the look of slate or wood. Proper maintenance includes regular inspections and replacing damaged shingles to ensure longevity.
Wood Shingles and Shakes
- Lifespan: 25-40 years
- Details: Wood roofing provides a natural and rustic look, often using cedar, redwood, or pine.
- Shingles: Machine-cut for a uniform appearance.
- Shakes: Hand-split for a more rugged texture. They offer good insulation properties but require regular maintenance, including cleaning to prevent moss and mold growth and treatments to prevent rot and insect damage.
Metal Roofing
- Lifespan: 40-70 years
- Details: Metal roofing is known for its durability, resistance to extreme weather conditions, and energy efficiency due to its reflective properties. Common types include:
- Steel: Often coated with zinc or a mixture of zinc and aluminum to prevent rust.
- Aluminum: Lightweight and resistant to corrosion.
- Copper: Offers a distinctive look that develops a green patina over time, but is more expensive.
- Zinc: Durable and environmentally friendly, as it’s recyclable. Metal roofing can be installed as large panels or as smaller shingles and requires minimal maintenance.
Clay and Concrete Tiles
- Lifespan: 50-100 years
- Details: Clay and concrete tiles are prized for their durability, fire resistance, and ability to withstand harsh weather conditions.
- Clay Tiles: Available in traditional terracotta and various other colors. They are heavy, so the roof structure must be able to support them.
- Concrete Tiles: Less expensive than clay and can be designed to mimic the look of clay, slate, or wood. Both types require minimal maintenance but should be inspected regularly for cracked or broken tiles.
Synthetic Roofing Materials
- Lifespan: 20-50 years
- Details: Synthetic roofing materials are designed to mimic the appearance of natural materials while offering enhanced durability and lower maintenance.
- Synthetic Slate and Shake: Made from rubber, plastic, or polymer blends, differ from roofs like asphalt as they are lighter and often more cost-effective than their natural counterparts.
- Composite Roofing: Blends of various materials to achieve specific aesthetic and performance characteristics. These materials are resistant to impact, fire, and extreme weather conditions.
Green Roofs
- Lifespan: 30-50 years
- Details: Green roofs, also known as living roofs, consist of a waterproof membrane, a growing medium, and vegetation. They provide several benefits:
- Insulation: Improved energy efficiency by providing additional insulation.
- Stormwater Management: Reduces runoff and improves water management.
- Aesthetic and Environmental Benefits: Enhances urban biodiversity and provides green space. Maintenance includes regular watering, weeding, and ensuring proper drainage.
Slate Roofing
- Lifespan: 75-200 years
- Details: Slate roofing is one of the most durable and long-lasting roofing materials available. It is made from natural stone, providing a sophisticated and timeless look.
- Natural Slate: Offers unparalleled longevity and resistance to fire and weather.
- Synthetic Slate: Made from rubber and plastic composites, it provides a similar look at a lower cost and weight. Slate roofs require professional installation and regular maintenance to replace any broken tiles.
Roofing Material Factors to Consider for Longevity and Design
With so many great roofing materials to choose from, it can be hard to feel like there is only one best choice. To make the decision easier, consider all of the following factors that apply to the roofing material that meets your needs.
Climate and Weather
- Temperature Extremes: Some materials perform well in hot climates as they reflect sunlight and reduce cooling costs, while others may deteriorate faster under intense heat.
- Rain and Humidity: In areas with heavy rainfall or high humidity, materials like metal or slate, which are less susceptible to water damage and mold, are preferred.
- Wind and Storms: For regions prone to high winds or storms, durable materials with high wind resistance ratings are advisable.
- Snow and Ice: In cold climates, materials that can withstand freeze-thaw cycles, are ideal to prevent damage from snow and ice accumulation.
Installation Process
- Complexity: Some materials, like slate or tile, require specialized skills and more time for installation.
- Ease of Installation: Materials like asphalt shingles are relatively easy to install, making them a popular choice and reduce labor costs.
- Roof Structure: The existing roof structure must be able to support the weight and type of material chosen, affecting the ease and cost of installation.
Weight
- Structural Support: Heavier materials like slate and concrete tiles require a stronger roof structure, which may necessitate additional structural reinforcement.
- Transport and Handling: Heavier materials can also be more challenging and costly to transport and handle during installation.
Cost
- Initial Cost: Materials like asphalt shingles are generally cheaper initially, while others like slate or metal can be significantly more expensive.
- Long-Term Cost: Higher initial costs of durable materials like metal or slate may be offset by their longevity and lower maintenance requirements.
- Life Cycle: Considering the total cost over the roof’s lifespan, including installation, maintenance, and potential replacement costs, is crucial.
Maintenance
- Durability: Materials like metal and slate require minimal maintenance compared to others like wood, which needs regular treatment to prevent rot and insect damage.
- Repairs: The ease and cost of repairing or replacing damaged sections can vary widely between materials. For example, replacing individual asphalt shingles is relatively simple, whereas repairing a slate roof can be more complex and costly.
- Cleaning: Some materials, such as certain types of shingles, may require regular cleaning to prevent algae and moss growth, especially in humid climates.
Design
- Aesthetics: The appearance of the roofing material can significantly affect the overall look of the home. Materials like tile, slate, or wood shingles offer distinct and appealing aesthetics that can enhance the home’s curb appeal.
- Versatility: Some materials come in a variety of colors and styles, providing more options to match the home’s design. Asphalt shingles, for instance, are available in numerous colors and patterns.
- Architectural Style: Certain materials are better suited to specific architectural styles. For example, clay tiles are often used in Mediterranean-style homes, while slate might be preferred for historic or high-end homes.
