Composition
Composition Roofing Material
Composition roofing comes in an extensive choice of patterns, styles, and colors. Composition shingles are the most common application today.
Laminate Shingles
One of the newer and most popular composition shingles today is the laminated shingle also known 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.
Installation
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.
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.
Flashings
Usually, pre-painted galvanized steel 28 gauge or thicker is used on the perimeter of the roof and where shingles meet penetrations such as walls, chimneys, skylights, etc.
