A durable roof is made of more than just shingles. Protecting your home requires a complete roofing system that creates a waterproof barrier, defends against nature’s elements, and provides proper ventilation. In San Diego, homeowners need to think about the extra heat and sun exposure, too.

Your total roof system needs to consist of barriers, underlayment, starter shingles, hip and ridge shingles, ventilation products, and insulation.

In order to prevent leaks, you need to start with the right underlayment.

Water barrier products, such as the Owens Corning Weather Lock, protect your new roof from wind, rain, and other elements, while barriers and underlayment stop moisture and mold from seeping through your roof.

For added quality, a synthetic material like Owens Corning ProArmour with Fusion Back Coating Technology is stronger than traditional felt underlayment, reducing the chance of tears and leaks.

Terminology of a Roofing System

Your roof protects your most important investment – your home. Here are all the components of a high-quality roofing system, including some of the main parts we mentioned above:

• Deck: The structural base of the roof, which is usually made of wood.

• Underlayment: The protective material between the deck and shingles.

• Eave: The lower border of the roof that overhangs the wall.

• Rake: The outer edge of the roof.

• Flashing: The intersection of two roof planes.

• Ridge: The horizontal peak formed from intersection of two roof planes.

• Exposure: The portion of each shingle exposed to nature’s elements.

• Ice and water barrier: Waterproofing material used to protect from ice and rain.

• Metal drip edge: A strip of non corrosive metal to help water runoff.

• Valley: An intersection of two, sloping roofs, joined at an angle, which provides water runoff.

• Off-ridge exhaust vent: The vent that allows warm air to escape the attic, which is usually located on the upper half of the roof.

• Ridge vent: The vent on the peak of the roof, that allows warm air to escape from the attic.

• Undereave vent: The vent that draws cool air into the attic, which is located under the eaves.
