The Importance of Roofing Ventilation
Your roofing system not only protects your home from damaging external conditions but from internal ones as well. The air inside your attic can cause serious damage if the space is not properly ventilated. Many roofing contractors in Houston install improperly ventilated roof which will fail and void the factory warranty. Here are some things to watch out for.
WHY YOU NEED ROOF VENTILATIONOne of the most important parts of your roofing system is ventilation. If not properly ventilated, your roofing system and the contents of your attic are at high risk of damage. The moist, hot air in Houston gets trapped in your attic and causes condensation to build up. This condensation can rot the decking, rust nails, and allow mold and mildew growth. By utilizing the correct combination of intake and exhaust vents, the air in your attic can be properly vented and prevent costly damage.
TYPES OF ROOF VENTILATIONMost air intake vents are located under the soffit. There are also gable end vents, hip vent, and fascia vents which allow ambient air to flow into the attic. The most commonly utilized exhaust vents are called ridge vents. Ridge vents utilize pressure differences that pull air from inside your attic and then replaced with cooler air from the intakes. Other common exhaust vents include different types of turbines, louvers and powered exhaust fans.
PROPER INSTALLATIONIf the right combination and type of intake and exhaust are not used, your roof can be damaged. And, YES, you CAN over-ventilate your roof! This is as serious a problem as not using enough ventilation. Make sure you choose a contractor like Houston Roofing & Construction who can properly calculate the correct number and type of intake and exhaust vent products for your particular roof.
