Attic VentilationTexas Star Roofing is versed in all types of ventilation and understands the importance of a properly installed system. Roof ventilation, or more accurately, attic ventilation, is an important component of your roof that oftentimes is overlooked. Ventilation can be addressed cost-effectively whether the roof is being replaced or not. Shingle, paint and insulation warranties are based on FHA Minimum Property Standards, and the Universal Building Code among others. They call for a minimum of one square foot of ventilation for every 300 square feet of attic space. One half of the vent area should be intake, and the other half should be exhaust. For example, a 3,000-square-foot home would require 10 square feet of ventilation, five square feet of intake, and five square feet of exhaust. Three important reasons our professionals ventilate include:
- Shingles — Shingles deteriorate twice as fast when installed over improperly (voids manufacturer warranty) ventilated attics. Heat causes them to dry out, become brittle, and blister, causing a loss of granules.
- Attics — Ventilation reduces the attic temperature, relieving pressure from the air conditioner and duct work. A cooler attic also reduces the amount of heat transfer into the house.
- Moisture — Proper ventilation helps prevent moisture from condensing in cold weather, which can damage insulation, rafters and roof deck. Trapped moisture rots wood, robs insulation of its R-value, and even contributes to the growth of mold in the attic.
