Roof vents help your home breathe. Not literally, of course, but this is why the best roofing contractors always factor proper venting when building a new roof. As one such contractor, Classic Remodeling Corp. shares an in-depth look at this small-yet-essential roofing component.
Problems Caused by Improper Ventilation
Ideally, the roof and attic should be close to outdoor temperatures. Different interior and exterior roof temperatures cause uneven expansion and contraction, which can later result in warping and other structural issues. Moisture level in the attic should likewise be minimal. Since most of the roofing structure is made of wood, exposure to excess trapped moisture, combined with trapped heat, can lead to roofing problems that often precede an unplanned roof replacement.
Heat and moisture can also damage attic insulation, as most types of insulating material tend to form clumps when they absorb too much moisture. Warm and moist areas also make the perfect breeding grounds for mold and mildew growth, both of which can trigger respiratory issues and allergies.
As part of the attic ventilation system, roof vents are an essential part of a modern roofing system. Since heat tends to rise, roof vents are positioned at the ridges. As heat is vented out, the resulting air pressure allows cool and fresh air into the vents along the roof edges. If the roof is built properly, air movement should be continuous along these areas. Roofing manufacturers like GAF offer complete roofing systems with roof vents that allow airflow while blocking insects and small animals from accessing the attic.
For large roofing systems that require more than passive ventilation, solar-powered exhaust fans can be installed near the roof ridge. They function the same way as rotating roof ventilators often seen on commercial properties, except that exhaust fans are smaller and require little maintenance. More importantly, they keep your roof cool without sacrificing your roof’s look.
