A new roof cover is a big investment.
We want to help you get a quality roof system at a fair
price from a professional roofing contractor.
Roof system components
All steep-slope roof systems (i.e., roofs with slopes of
25 percent or more) have five basic components:
1. Roof covering: shingles, tile, slate or metal and underlayment
that protect the sheathing from weather.
2. Sheathing: boards or sheet material that are fastened
to roof rafters to cover a house or building.
3. Roof structure: rafters and trusses constructed to support
the sheathing.
4. Flashing: sheet metal or other material installed into
a roof system's various joints and valleys to prevent water
seepage.
5. Drainage: a roof system's design features, such as shape,
slope and layout that affect its ability to shed water.
Asphalt shingles possess an overwhelming
share of the roofing market and can be reinforced with organic
or fiberglass materials. Although asphalt shingles reinforced
with organic felts have been around much longer, fiberglass-reinforced
products now dominate the market.
Organic shingles consist of a cellulose-fiber
(i.e., wood) base that is saturated with asphalt and coated
with colored mineral granules.
Fiberglass shingles consist of a fiberglass
mat, top-and-bottom layers of asphalt, and mineral granules.
Wood shingles and shakes are made from
cedar, redwood, southern pine and other woods.
Wood shingles are machine sawn; shakes are handmade and
rougher looking.
A point to consider; Some local building codes limit the
use of wood shingles and shakes because of concerns about
fire resistance.
Metal, There are two types of metal roofing
products: panels and shingles. Numerous metal panel shapes
and configurations exist.
Metal shingles typically are intended
to simulate traditional roof coverings, such as wood shakes,
shingles and tile.
Apart from metal roofing's longevity,
metal shingles are relatively lightweight, have a greater
resistance to adverse weather and can be aesthetically pleasing.
