Homeowners considering a roof replacement must choose a roofing material that fits within their expectations of how long it will last. There are many types of roofing materials available today with varying lifespans of between 20 and 100-years or more. The following post will breakdown the lifespans of some of the most popular roofing materials used in the residential construction industry. In addition, it must be noted that regional weather conditions, the quality of the materials purchased, roofing maintenance and cleaning as well as the design of the structure plays an important role when it comes to the actual lifespan of the roofing material.
Expected Roofing Material Life Spans
• Asphalt 3-tab Shingles—20-years
• Asphalt Architectural Shingles—30-years
• Wood Shingles—30-years
• Metal Roofs—40 to 80-years
• Slate shingles, Concrete tile roofs and Clay Roofing Tiles—60 to 150-years
Roofing Types and Life Expectancy
Asphalt—three tab—shingles have held the title of the most popular roofing material for decades. This durable material consists of an asphalt/fiberglass base shingle covered with protective granules to add extra durability as well as color. They have held the top spot for so long due to their relative lower cost and ease of installation. The most common types of asphalt shingles last approximately 20 years, however higher-quality versions are available that can last up to 50 years.
Architectural Shingles are similar to asphalt shingles as they are composed of the same materials, and are recyclable as well. An extra tab or layer is added during manufacture to provide both increased durability as well as aesthetic appeal. The average life span of an architectural shingle roof is 30 years.
Wooden shingles or shakes have been used for centuries and are still popular today. This durable roofing material is often manufactured using hard woods or composite wood materials. In moderate climate zones, wooden shingles and shakes can last approximately 30 years. Before purchasing, you should verify with your roofing contractor or local building department regarding their use, as many states do not permit the manufacture or installation of wooden shingles and shakes.
Metal roofing materials can last between 40 to 80 years depending on regional climate conditions. Traditionally, metal roofs consisted of simple, corrugated panels that offered little in aesthetic appeal. Today, metal roofing products are available to fit most any architectural style. The attractive panels are often manufactured using steel, aluminum or copper. A metallic coating and painted finish is added to steel panels during manufacture to prevent rust and increase aesthetic appeal. Aluminum panels do not require the metallic coating as they naturally resist rust and corrosion.
