by Introduction to Common Roofing Materials
One of the most important decisions a homeowner faces is selecting a durable roofing material. The roof protects the entire home from weather elements like rain, snow, wind, and sun damage. Homeowners have several roofing material options to choose from, each with their own pros and cons.
Asphalt Shingles
Asphalt shingles are the most widely used roofing material due to their affordability and availability. Made from fiberglass coated with asphalt and gravel on the surface, asphalt shingles are lightweight and economical. They come in various styles resembling wood, slate, or tiles for aesthetic appeal. Asphalt shingles are easy to install over existing Roofing Systems. However, they have a shorter lifespan of 15-20 years compared to other options. Intense heat can melt asphalt shingles and cause damage. Proper attic ventilation is important to keep asphalt roofs cool.
Concrete and Clay Tile Roofs
Concrete and clay roof tiles have classy appeal resembling natural materials like terra cotta or slate. Made from concrete or fired and glazed clay, tile roofs have fireproofing and insulation properties in addition to aesthetic benefits. However, tiles are heavy requiring strong roof decking to support the weight. Tile installation also requires expertise and is more expensive than asphalt shingles. But tiles have longevity up to 50 years with low maintenance. Several profile designs, textures, and colors are available for tile roofs.
Metal Roofing Systems
Metal roofs made of steel, copper, aluminum or zinc have gained popularity recently. Lightweight and rust-resistant steel is the most common type used. Some advantages of metal roofing include resistance to fire, impact, and wind uplift. With little maintenance, metal roofs last 50 years or longer. Unlike shingles, they do not need to be replaced after 15-20 years. Installing a metal roof is also simpler and faster compared to other materials. Nevertheless, the high material and installation costs of metal roofs negate their longevity benefits for some homeowners.
Green or Sustainable Roofing
Environmentally-friendly green roofing or cool roof systems using plants or special roofing materials aim to reduce heat absorption on homes. Extensive or intensive green roofs planted with modular trays of vegetation provide insulation and manage stormwater runoff naturally. Cool roofing made of white-colored or specially formulated materials reflects solar heat and stays 40-60°F cooler than traditional roofs. This minimizes air conditioning needs and heat transfer into attics. While offering energy savings, green or cool roofs require specialized installation by licensed contractors. Their higher cost limits widespread adoption currently. However, more homeowners are investing in sustainable roofing for long-term benefits.
Built-Up and Single Ply Membrane Roofing
Commercial and industrial buildings commonly employ built-up roofing systems comprising multiple layers of bitumen and roofing felts. Built-up roofs last decades but require maintenance, repair costs, and potential leakage issues. Single ply membranes made of synthetic rubber, thermoplastic or modified bitumen provide a monolithic waterproof surface as an alternative. Easier to install than built-up variants, single ply can be mechanically fastened or fully adhered based on contractors’ preference. Both systems have flat profiles suitable for large, flat roof areas. Regular inspections and repairs help maintain membrane roof performance over 20-30 years.
Roof Installation, Inspection and Maintenance
Regardless of material choice, proper installation is vital for roof longevity. Contractors must follow manufacturers’ guidelines for surface preparation and application methods. Homeowners should verify contractor licensing and request warranty documentation. Regular inspections every 2-3 years allow early detection of damage from weathering, foot traffic or falling objects. Drains and gutters must be cleaned periodically to prevent waterlogging. Trees surrounding a house require pruning to avoid broken branches hurting the roof. Damage repairs like replacing cracked or missing shingles maintain a roof’s watertight seal. With scheduled maintenance, most roofing materials can function effectively for decades. Selecting the suitable system and contractor ensures a home’s roof fulfills its protective function for a long time.
