Ventilation is very important when you replace a roof
We work hard at making sure we know what you need, using formulas rather than assumptions when determining the right amount of ventilation and other materials necessary. Our consultations include the right air exchanges in your attic, so your attic is cooler and your roof last longer.
In cold weather, warm air generated by laundry, showers, dishwashing, and cooking can linger in the house and cause moisture build-up. In the summer, heat build-up encourages premature aging and cracking of wood and roofing materials. Unwanted heat can also transfer back down into living areas, reducing energy efficiency.
The only way to combat these problems is with a balanced ventilation system. In a balanced system, wind blowing over the ridge creates a negative pressure that draws the warmer air out of the attic. Replacement air enters through the undereave or soffit vents, bathes the underside of the roof, and exits at the ridge cap through ridge vents, roof vents, or gable vents. Even with no wind, the natural convection action of rising warm air maintains a continuous airflow along the underside of the roof. It’s a system that works year-round with no moving parts or energy consumption.
Roof ventilation allows outside air to flow naturally upward and out of the attic, promotes a cooler, drier attic and helps prevent moisture from becoming trapped in insulation, structural wood, shingles and the roof deck. It also helps prevent rotting, mildew, drywall damage, peeling paint and warped siding, and provides year-round performance for consistent ventilation without energy consumption.
