Composition Roofing Material
Composition roofing comes in an extensive choice of patterns, styles, and
colors. Composition shingles are the most common application today.
One of the newer and most popular composition shingles today is the laminated
shingle also know as architectural or dimensional shingles. These shingles
distinctive in their design have had at least two shingles laminated together
to create the illusion of depth.
The colors and color blends of the shingles are seemingly endless and vary
from manufacturer to manufacturer. The laminated shingles all carry limited
lifetime warranties.
The ridge cap is made in two styles: the standard or flat ridge and the
high-profile ridge. The high-profile ridge has a look similar to tile
and accents hips, ridge and rakes.
Typical composition installation involves underlayment, flashings, vents,
fasteners and shingles.
Underlayment: Acting as a moisture and condensation barrier, it comes in
saturated felt and self-adhering membranes.
Flashings: Usually pre-painted galvanized steel 28 gauge or thicker, is
used on perimeter of roof and where shingles meet penetrations such as
walls, chimneys, skylights, etc.
Vents: Used to circulate air in attics or confined spaces. Vents help keep
condensation from forming during cool weather and extreme temperatures
during hot weather. There are typical square gravity vents, power vents
and ridge vents which can be concealed underneath the ridgecaps.
Fasteners: Galvanized hand nails, coated pneumatic coil nails and zinc
coated staples. Coil nails and staples also come in stainless steel.
