Different types of roofing materials


Today, advanced roofing materials provide an unprecedented range of alternatives, as well as new looks for existing materials.     

    1. Solar tiles

Advanced solar collectors integrate seamlessly into existing shingles, generating up to 1 kilowatt of energy per 100 square feet. They’re particularly good for sunny roofs in homeowners’ associations that forbid typical solar panels.

    2. Asphalt shingles

Asphalt shingles are the most common roofing materials in America because they’re effective in all environmental conditions. Quality varies widely, so ask whether they pass the ASTM D3161, Class F (110 mph) or ASTM D7158, Class H (150 mph) wind tests and the AC438 durability test.

    3. Metal roofing

Metal roofing comes in vertical panels or shingles resembling slate, tile and shake – and lasts about 60 years. Metal excels at sloughing off heavy snow and rain, won’t burn and resists high winds.

    4. Stone-coated steel

Interlocking panels mimic slate, clay or shingles and resist damage caused by heavy rains (up to 8.8 inches per hour), winds of 120 miles per hour, uplifting, hail and freeze-thaw cycles.

    5. Slate

Slate roofing lasts more than 100 years. It won’t burn, is waterproof and resists mold and fungus. Slate is effective in wet climates but is expensive, heavy and may be easily broken when stepped on. Keep this in mind if you live in an area that experiences hail.
    6. Rubber slate
Rubber slate looks natural and can be cut with a knife to fit intricate roofs like those found on Victorian homes. Rubber slate roofs can last 100 years but can be damaged by satellite dishes and walking – so may also be susceptible to damage by hail, similar to slate.
    7. Clay and concrete tiles 
Clay and concrete roof tiles can withstand damage from tornadoes, hurricanes or winds up to 125 miles per hour and even earthquakes, according to "A Summary of Experimental Studies on Seismic Performance of Concrete and Clay Roofing Tiles" by the University of Southern California for the Tile Roofing Institute.
    8. Green roofs
Green roofs are covered with plants and can improve air quality, reduce water runoff and insulate homes to reduce urban heat islands.
    9. Built-up roofing
This heavy roofing consists of layers of asphalt, tar or adhesive topped with an aggregate and is only for flat roofs. Tar and gravel roofs, also for flat roofs, are best for roof-top decks with heavy foot traffic.
