Types of Roofing
Types of roofing you can choose from:
BUILT-UP-ROOFING
Commonly referred to as; “Tar & Gravel” or “Hot Tar”.
A roof system with a demonstrated track record of 75 –100 years, which still to this day accounts for over
half of the flat roofing systems installed in California. A tough, durable system with multiple redundant layers of waterproofing
material, available in a variety of finishes.
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.
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.”
In addition to many high end 50 year and very distinctive lifetime designs. 20-year shingles are used on most starter homes
and have no texture. 30, 40, and 50 year shingles have a dimensional or architectural look with good curb appeal. The lifetime
design shingles 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 (A square is a roofing term for
a 100 square foot area).
DECK COATINGS
Attractive, durable and trafficable
fluid applied deck coatings. Available in GACO, Metacrylics and most other major coating manufacturers.
GREEN
ROOFING
Complete Green LEED approved, Title 24 compliant, green roofing systems. Including roof top gardens
to offset carbon footprint, energy savings and use of recycled materials.
METAL ROOFING
There
are two styles of metal roofing to choose from. Screwdown (using exposed fasteners) is used on most standard homes. 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.
(MODIFIED) FLAT ROOFING
Modified
roofing is made by all shingle manufacturers. It can be installed by many methods including "hot mopped", "self-adhering"
so no heat source is required, etc.. Modified roofing is used on most commercial applications as well as patio roofs and in
the waterproofing of walk on decks.
SINGLE-PLY ROOFING
Single-ply roofing is available in
Carlisle, Duro-Last or other major manufacturers, which do not require a flame for installation or a kettle. Systems typically
qualify for up to 20 year commercial warranties.
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.
SPRAY POLYURETHANE FOAM
Spray polyurethane foam, commonly referred to as SPF, is a spray-applied
insulating foam that is installed as a liquid and then expands many times its original size. High density roofing foam is
resistant to foot traffic and water. SPF has a high insulating value of R-6.0 per inch. The excellent insulation efficiency
of SPF can reduce heating and cooling usage dramatically. SPF insulates and eliminates thermal bridging through fasteners
or gaps in decking while providing a long-lasting roofing system that has a life expectancy that can be extended by re-coating
at 10-15 year intervals.
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.
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.
