Know Your Roof
1.
Hip & Ridge Shingles
These highly dimensional shingles add definition and style
to your roof's ridge line.
2. Ridge Vents
Ridge vents help keep air moving through the attic, balancing
the outdoor and indoor temperatures. A roof that's too hot
in the summer or too cold in the winter can result in damage
like a warped deck or cracked shingles. A well-ventilated
attic is key to a healthy roof.
3. Shingles
They come in a wide variety of distinctive choices to suit
ever budget and taste. And, all Owens Corning shingles have
a tough mat core that has become an industry standard for
quality in asphalt roofing.
4. Waterproofing Underlayment
Our waterproofing underlayment helps prevent leaks from water
buildup under ice dams in cold weather. Especially in coastal
areas, we can keep wind-driven rain from working its way in
between the shingles and deck.
More About Roofing Materials
The brochure,
Buying a new roof... and getting your money's worth, produced
by the National Roofing Contractors Association and State
Farm, describes six basic materials used in the manufacture
of roofing materials:
Asphalt
Shingles
- Representing the overwhelming share of the U.S. residential
market, asphalt shingles come in two types. Oldest style is
organic, consisting of a cellulose-filter (wood) base saturated
with asphalt and coated with mineral granules. Dominating
the market today is the fiberglass style consisting of a fiberglass
mat, top-and-bottom layers of asphalt, and mineral granules.
Typically, fiberglass offers greater durability.
Wood
Shingles and Shakes
- These are made from cedar, redwood, southern pine and other
woods. Shingles are machine-sawn, shakes are hand-hewn. (Some
local building codes limit their use because of fire resistance
concerns.)
Tile
- Made of clay or concrete, tile is as durable but fairly
expensive. Because of its weight, a homeowner should verify
fire structure would support the load, if tile were replacing
another type.
Slate
- Considered virtually indestructible, slate is quarried in
states such as Vermont, New York, Pennsylvania, and Canada.
Slate is more expensive than other materials and requires
more skill and experience to apply.
Metal
- Primarily perceived as a commercial roofing material, metal
shingles are being made to simulate traditional house roof
coverings. They are long-lasting, relatively light, fire resistant,
and effective look-alikes. They can be more vulnerable to
cosmetic damage.
Synthetic
- These products simulate traditional roof coverings but do
not necessarily have the same properties.
Roof Systems
All
roof systems have six basic components:
Roof
Structure
- Rafters and trusses that support the roof.
Deck/sheathing
- Boards or sheet metal fastened to the roof rafters.
Underlayment
-A sheet of asphalt-saturated material that provides a second
layer of protection for the roof deck.
Roof
Covering
- Exterior roofing materials such as shingles that protect
the sheathing.
Drainage
- The ability to shed water, primarily a function of design
(shape, slope, layout).
Flashing
- Sheet metal (usually) laid into the joints and valleys of
a roof to prevent water seepage.
