Although they are more common in desert areas, some tiles are suitable for use in cold climates. Tile roofs dominate on the Mission- and Spanish-style homes of the U.S. They are also the most easily recycled roofing material. Metal roofs last at least 40 years and can last as long as 75 years. Proper installation and good insulation are required to minimize noise from rainfall and wind “chatter.” Metal is lightweight, virtually fireproof, and particularly suited to thin-film solar power systems. Metal can be more expensive than asphalt, but except for copper, it is still among the cheaper roofing options. They come in various shapes and textures, from standing seam panels to shingles that resemble tile or slate. Metal roofing options include steel, aluminum, copper, and alloy strips. Whether sourcing locally or from a national brand, look for FSC-certified wood. Sourcing wood shingle or shakes from a local sawmill will reduce the greenhouse gases associated with transport and ensure a regionally appropriate wood species is used. Meticulous maintenance and mild climates can extend the lifespan to 50 years. Despite these vulnerabilities, wood roofs can last 25 to 30 years. However, composters will not accept chemically treated shingles. Including additional materials in the roof assembly can help them meet a Class A rating. Fire retardants can help wood shingles and shakes achieve a Class B fire rating. Untreated wood shakes are unrated for fire safety and therefore are not permitted by building codes in many areas prone to wildfires. Wood shingles can mold, split, or rot in wet climates. Prized for their natural look, handmade shakes have earned their reputation for being expensive, but machine-made wooden shingles do not cost much more than asphalt.
Although technically recyclable, most asphalt roof shingles end up in the landfill. Several asphalt tile manufacturers even offer solar-integrated asphalt roofs.Īsphalt roofs usually last 20 to 25 years, but some newer, high-quality products will last 40 years or more. Single-plane shingle roofs (also called 3-tab) are the easiest roof to retrofit with a solar panel system. Although slightly more expensive than basic three-tab asphalt shingles, laminate shingles perform better. They can be made to look like more expensive materials, such as tile, wood, and slate. Laminate shingles (also called architectural or dimensional) are fiberglass layered between asphalt and ceramic granules. It is so common that many people assume you are talking about asphalt shingles when you talk about roofing. Asphalt ShingleĪsphalt is the cheapest option. Natural roofing materials are not manufactured, so they are not included in the comparison chart. In this article, we consider the merits of the most common manufactured roofing materials.
#MARKLY SINGLE ROOF UPDATE#
When they do, we’ll update our sustainable roofing results. Our results are far from comprehensive, but as more consumers begin to demand this information, more manufacturers will begin to provide it. We’ve researched roofing materials and manufacturers to make buying an eco-friendly roof easier. But the impact of our roofing choices, both on our homes and on the environment, is too great to ignore. It can be even harder to find out if they recycle or work to minimize their environmental impact.
It’s not always easy to find out who makes your roofing material.
For many homeowners, the cheapest option is always the default choice while others choose a style they like and leave the details to a contractor. For most people, buying a new roof is one of the most important and expensive maintenance decisions for their biggest investment.
