Asphalt: Asphalt-saturated felt (good) and asphalt-saturated felt with fiberglass reinforcement (much better) is made in two grades; # 15 (called 15 pound) paper weighs about 8-12.5 pounds per 100 square feet, while # 30 paper is thicker and weighs approximately two times that.

Popular brand names consist of GAF DeckArmor and FeltBuster, Titanium and Owens Corning ProArmor, though there are numerous others on the marketplace that use good efficiency. Wetness and Ice Barrier AKA Ice and Water: A big volume of moving water flows through valleys where roofing system sections come together. The water can quickly wash beneath shingles.
Many roof professionals in climates with freezing winter weather condition likewise like to install a layer of moisture barrier at the eaves where ice dams may form. GAF’s moisture barrier is called WeatherWatch and Owens Corning calls its product WeatherLock. These are two of the many quality options.

Ridge vent: Ridge vent always needs the existence of soffit vents. The decking on your roofing system has, or must have, a space at the peak.
Ridge vent has a strong top and vents on the side. The ridge vent can be covered with cap shingles that will not obstruct the vent opening. Soffit vents: Perforated soffit is the easiest method to get ventilation at the soffit. If your soffit (the location under the eaves) is solid, then private vents must be installed.

Keep in mind: Make sure that the soffit vents are not covered with attic installation. Gable vents: These are especially handy when the attic has two gabled sides where vents can be installed. Cross-breezes efficiently move hot, damp air out of an attic. Roofing system vents: Any house, particularly big homes and homes with hip roofs, take advantage of offering heat other points of escape.
The correct amount of insulation in the attic lowers energy loss and the expense of running the HEATING AND COOLING system. Sufficient insulation will avoid ice dams when there is snow on the roof. In winter season,. When heat from your house increases through the roofing because the attic does not have adequate insulation (R-60 in freezing environments), snow on the roof melts.
