Types of Roofing

Types of roofing you can choose from:

Composition is far and away the most popular and widely-used home roofing material. It typically comes in 20-, 30-, 40-year “lives.” (There is also a lifetime variety) 20-year shingles are used on most starter homes and have no texture. 30-year shingles have a dimensional or architectural look with good curb appeal. 40-year shingles and higher are considered specialty shingles and recommended as an upgrade to consider.

Single ply roofs are the most common products use for low slope roofs and decks on homes, industrial and commercial projects. PVC membranes perform the best offering 15-, 20-, 25- and lifetime warranties. They are energy efficient and environmentally friendly. This product also complies with the new Cool Roof requirements

This type is considered a "lifetime" roof and is typically used on upper-end homes. Weight is an issue so a home must be engineered, or otherwise evaluated, to handle 1,000 pounds per square of roofing space. Most concrete-tile orders take several weeks to be fulfilled; only small amounts of tile are normally in stock.

Clay is considered an upgrade over concrete tile. Special underlayment is required. Clay can be offered in one piece and two piece styles. Two piece tiles require perpendicular batten boards and additional labor.

There are two styles of metal roofing to choose from. Screwdown (using exposed fasteners) is used on most agricultural and industrial buildings. The screws have a tendency to "back out" after seven to ten years, requiring normal maintenance. Standing seam (using concealed fasteners) is considered an upgrade and is the more costly of the two, it is recommended for residential and office buildings.

Two styles of wood shingles are available. Wood shingles are the smaller of the styles (18") and installed with 5" exposure. Wood shakes are 24" installed using #30 felt at a 10" exposure. Most codes require that any installed wood shingles be fire treated. Wood shingles are high priced and in many instances require at least a four week lead time.
