Composition Roofing Material

3 Tab Roof

3-tab shingles offer economical good looks and lasting performance with warranty years ranging from 30 to 20 years.

Composition roofing comes in an extensive choice of patterns, styles, colors and warranties. In the past, the most common composition shingle was 3-tab which is still widely used today. The 3-tab shingle has a flat appearance with 3 tabs per shingle - hence the name. It has warranties ranging from 20 years to 35 years.

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 two shingles laminated together to create the illusion of depth.

Landmark Crop

The colors and color blends of the shingles are seemingly endless and vary from manufacturer to manufacturer. The laminated shingles have warranties ranging from 25 years to 50 years. The 40 year Presidential shingle takes after woodshingles in design, but has a granular look.

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.
