Roofing serves as part of your house’s defense against the elements, and investing in the right material can make all the difference in keeping your home protected. Between asphalt shingles, metal roofing, tile, and slate, there are many types of roofing from which you can choose, and each has its own advantages and disadvantages. Read our guide below to learn how these roofing materials compare with respect to cost, durability, and maintenance requirements.
Asphalt Roofing Shingles
Asphalt shingles are the most common roofing material for residential homes, and offer a balance of durability and affordability.
Types of Asphalt Shingles
There are three main types of asphalt shingles: three-tab shingles, architectural shingles, and premium shingles. Three-tab shingles are the most traditional shingles, and are affordable and flat-shaped. Architectural shingles, also known as dimensional shingles, have a more textured, layered look, and are more durable than three-tab shingles. Premium shingles are high-end options that mimic slate or wood, but offer even better protection.
Durability and Lifespan
Basic three-tab shingles typically last between 15 and 20 years, architectural shingles can last for up to 30 years, and some premium options include warranties that last for up to 50 years.
Cost-Effectiveness
Asphalt shingles are the most affordable roofing option up front, but they require more frequent replacements and maintenance.
Wood Roofing Shingles
Wood shingles offer homeowners a classic, rustic appeal. Cedar is the most popular choice for wood roofing because it’s naturally resistant to decay and insects.
Installation Considerations
Installing wood shingles is a nuanced task that requires getting the shingles wet, then drying them out to maintain their watertightness. This is necessary to prevent rot, mold and mildew.
Ventilation Requirements
You must keep wood shingle roofs ventilated to avoid issues. Homeowners once used skip sheathing to maintain proper air circulation, but contemporary solutions include special venting materials that lift the shingles off the substrate for better airflow.
Cost and Lifespan
Wood shingles can cost twice as much as asphalt, or more. They can last up to 50 years, though, which makes them a valuable long-term investment.
Metal Roofing
Metal roofing has gained popularity among homeowners because of its durability and long lifespan. It protects against the elements especially successfully, and can outlast many other roofing materials.
Types of Metal Roofing
There are many types of metal roofing available to homeowners. Aluminum is lightweight and corrosion-resistant, which makes it suitable for coastal areas. Copper is a premium option that is visually striking and lasts long, while steel is cost-effective, whether it’s galvanized or galvalume-coated. Zinc, finally, is especially durable and develops a patina over time.
Benefits of Metal Roofing
Metal roofs are wind-resistant, fire-resistant, energy-efficient, and can successfully shed water. They require very little maintenance.
Cost and Lifespan
Metal roofing can cost five times as much as asphalt shingles, but it lasts much longer than other roofing types. A metal roof can last for up to 100 years if you install it correctly and properly maintain it.
Tile and Slate Roofing
Tile and slate roofing materials are common among high-end homes and historic restorations.
Clay and Concrete Tiles
Clay and concrete tiles are available in many different designs, such as traditional Spanish tile and more modern tile. Tiles are durable, fire-resistant, and can last for more than 100 years.
Slate Roofing
Natural slate can last for centuries if you properly install and maintain it. It also offers a unique appearance.
Structural Considerations
Tile and slate roofing materials are much heavier than other options. Your home’s structure must be able to support the weight of these materials, especially in areas that feature shallow roof pitches.
Green Roofs
Green roofs are environmentally friendly options that incorporate vegetation into their designs.
Types of Green Roofs
There are three primary types of green roofs: extensive, intensive, and semi-intensive. Extensive green roofs feature shallow soil layers and low-maintenance plants, which makes them suitable for homes with limited load-bearing capacities. Intensive green roofs feature deeper soil layers and a wider variety of plants that collectively resemble traditional gardens. Semi-intensive green roofs are a combination of the two. They offer diverse plant options and require only moderate maintenance.
Benefits of Green Roofs
Green roofs manage stormwater successfully, offer improved insulation for homeowners, and add more biodiversity to any property. These features can make your home more energy-efficient, reduce your carbon footprint, and provide nearby wildlife a habitat.
Cost and Maintenance
Green roofs are more expensive than other roofing types because they require structural support, waterproofing, and special installation techniques. The environmental benefits they offer can lead to long-term energy savings, though. Maintenance requirements depend on the type of roof you choose: Extensive roofs need little upkeep, while intensive roofs call for more frequent care.
Factors to Consider When Choosing Roofing Materials
Consider your budget for installation, maintenance requirements, and the weather conditions in your area when deciding which type of roofing material is best for you. You must also think about how long you want your roof to last, as well as local building codes and potential restrictions. Consult with local roofing professionals if you need help making the right choice.
