Proper ventilation 

Owens corning roofing system 
A high-performance roof takes more than just shingles. The performance of any roof depends on an entire system of Roofing Essentials™ accessory products working and performing together, including ventilation, hip and ridge shingles, underlayment, and attic insulation. The Owens Corning Roofing System is a lineup of essential products that can help provide maximum durability for your roof, and the most protection for your home.

Typical household activities can wreak havoc on a roof and attic if proper roof ventilation is not provided: 

■In the summer, heat build-up encourages the premature aging and cracking of wood and other roofing materials. Unwanted heat also can transfer back down into living areas - which reduces energy efficiency.

■In cold weather, warm air generated by laundry, showers, dish washing and cooking can linger in the house and cause moisture build-up.


The only way to combat these problems is with a balanced Top of the House® roofing system. That means it’s important to have proper ventilation, plus the appropriate amount of attic insulation to maximize performance.
In a balanced system, wind blowing over the ridge creates negative pressure that draws the warmer air out of the attic. Replacement air then enters through the undereave or soffit vents, bathes the underside of the roof, and exits at the ridge cap through ridge, roof or gable vents. Even without wind, the natural convection action of rising warm air maintains a continuous air flow along the underside of the roof.

Ultimately, proper ventilation — along with attic insulation — helps maintain a comfortable temperature inside a home, increase energy efficiency, prevent moisture damage and contribute to the longevity of a roof.

Ventilation is an important component of Owens Corning's Complete Roofing System. These Owens Corning ventilation products will help prevent damage and premature aging caused by moisture in the winter and excess heat in the summer.

When it comes to roofing, there are many options available. Among these options includes asphalt shingles. Asphalt shingles happen to be one of the most popular roofing options. They offer several benefits which include easy installation, affordability, versatility, and stylish good looks. Furthermore, asphalt shingles don't require any specialized accessories for the roof edges, wall terminations, and chimney or vent flashings.

Asphalt shingles traditionally come in 3-tab profiles. However, you will now see newer homes that have steeper roof pitches coming in laminate shingle profiles. A wide range of "architectural" shingles are available, whose profiles suggest the random shadows and patterns of slate, wood shingles, or ceramic tile. Furthermore, you should know that there are also two kinds of asphalt shingles on the market which include fiberglass shingles and organic-mat shingles. Both types are made with asphalt.

Quality and durability are important factors to consider with roofing materials. Asphalt singles come with a wind warranty. Quality shingles range from a 60 mph wind warranty to a 110 mph wind warranty. There are also several other options in between. Keep in mind, however, that warranties are a marketing device and are not a reliable predictor of lifespan.

To ensure quality, be sure to demand shingles that meet industry manufacturing standards. New shingle products are designed to resist damage from impact and high winds. Several manufacturers offer asphalt shingles designed to resist the effects of severe weather such as wind and impact from flying debris or hail. Make sure that you do your homework before selecting just any asphalt shingle for your roof.

It’s easy to find a shingle that will suit your home because there is such a wide range of colors and patterns available to choose from. If you find yourself having a hard time selecting one that will best suit your home, consider asking a Klingelhut roofing specialist to help you out. They can usually direct you to homes that have examples of different shingles. Seeing the shingles on real homes gives you a much better idea of what to expect.
