Most consumers, roof system designers and roofing contractors
choose asphalt shingles for steep-slope roof coverings. Asphalt
shingle products, the most widely used steep-slope roof covering in
the United States, are available in a wide array of styles and
colors. This variety enables asphalt shingles to satisfy a majority
of aesthetic and economic criteria for steep-slope structures.
Other conventional materials used for steep-slope roof coverings
include wood shakes and shingles, slate, clay and concrete tile,
and standing-seam metal panels. Although they enjoy a lesser share
of the steep-slope roofing market than asphalt shingles, each of
these products has a definite market niche.
In addition to these conventional materials, an assortment of
new, nontraditional steep-slope roof coverings are available. This
product group includes plastic or resin-based tile, simulated slate
and wood, synthetic slate and tile, individual metal shingles,
horizontal metal panels, and natural and synthetic thatch.
