All material options are viable with the focus being the installation. Existing materials (matching a house), aesthetics, budget, warranty, and life span of a roof all need to be factored in when deciding which is best for your specific home or detached garage. The list below highlights the most common roofing used, but there are others like slate, clay tile, and rolled roofing.
Shingles are made from fiberglass, asphalt, and minerals. Asphalt shingles warranties and life expectancy can range from twenty year to the lifetime of the property owner (50 Years). The first type is called a 3-Tab shingle due to the design of three 12” tabs on each individual shingle. This is the cheapest option and has an expected life expectancy of 12-20 years. Dimensional shingles as known as Architectural shingles are the most popular type of shingle being installed due to better curb appeal (more variation in color and depth due to the 2 layers that makes up the shingle), longer manufacture warranty, higher wind resistance, better resistance to hail impacts and Includes protection against black algae stains. This type has a life expectancy of 20-50 years. Other shingle options are designed to mimic the aesthetics of stone slate or shake roof and are made similarly to an architectural shingles.
The two distinct differences in options are exposed fasteners and hidden fasteners commonly known as Standing Seam. There are also metal options to match the profile of shingles, shake, slate and tile. Exposed fasteners roof expected life span is 15-30 years when installed correctly and screws can be replaced to extend life even longer. Standing seam roof expected life span is 50-80 years.
EPDM rubber is used and is ideal for any roof that is less than a 3/12 pitch. The expected lifespan of a rubber roof is 40-50 years.
