Why Attic Ventilation Matters
Thought it may seem strange to want a “hole” in your roof, ventilation plays a vital role in your roof’s integrity. Without ventilation — whether it’s a roof fan, electric roof vent, ridge vent, soffit vent, or another type of ventilation, unfinished attics will develop stagnant air. Without any air flow, attic temperatures soar in summer and go below freezing in winter. Attic fans and roof vents, however, let out stale air and bring air into the attic from outside. This prevents big temperature extremes and maximizes the performance of your roof.
Got Moisture Problems? Use a Roof Fan.
Water vapor can enter unfinished attics easily, typically rising from the lower level of the house. This moist air condenses on the home’s framing and can cause mildew problems and icicles in the attic during different seasons. This can damage the underside of your roof decking, rafters and insulation. When allowed to accumulate unchecked, you can find insect infestations and wood rot. Electric powered roof fans send this moist air out. It is more powerful than convection currents because it uses rotating fan blades to draw air out of the attic. Gable fans can use solar or electric powered motors, providing reliable power to create healthy air flow through the attic. Currently, electric roof fans move the largest quantity of air and are recommended for homes that tend to have moisture problems.
Just Need Temperature Stabilization and Air Flow? Use Convection Vents.
Roof vents that rely on natural convection currents are also effective when you aren’t dealing with a moisture issue. When hot air rises, it gets sent through the convection vent naturally. Air also moves naturally when cool air drops. Roofers prefer to install convection vents close to the peaks of sloped roofs. Ridge vents and soffit vents are the most popular types of convection vents that are effective in stabilizing roofs and attic environments.
