Types of Roofing
Types of roofing you can choose from:
COMPOSITION SHINGLES
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 an unlimited-life 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.
CONCRETE TILE
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 two months to be fulfilled; only small amounts of tile
are normally in stock.
CLAY TILE
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. Two piece clay is a minimum of $150/square more than one piece.
SLATE ROOFING
Slate is a very expensive and heavy material. In order to
install slate roofing, a house must be engineered to support over 1,000 pounds per square. There is normally a two-month lead
time for the product and typically a lengthy installation period.
SYNTHETIC SLATE
Not as pricey as real slate but also not as heavy. No special bracing is required as most homes can handle the weight.
Allow at least six weeks for material and extended time for installation.
WOOD
SHINGLES
Two styles of wood shingles are available. Wood shingles are the smaller of the styles (18") and
installed over open lathe at a 5" exposure. Wood shakes are 24" installed using #30 felt at a 10" exposure.
Most city codes require that any installed wood shingles be fire treated. Wood shingles are high priced and require at least
a four week lead time.
(MODIFIED) FLAT ROOFING
Modified roofing is
made by all shingle manufacturers. It can be installed by the "self-adhering" method so no heat source is required.
Modified roofing is used on most commercial applications as well as patio roofs and in the waterproofing of walk on decks.
Single-ply roofing also is available in TPO and PVC which does not require a flame for installation and carries a 15 year
warranty.
