Kent Roofing: Article About Roof Vent Features
Roofs may appear to be closed systems, but they actually breathe with the surrounding atmosphere. There are strategic vents allowing air into the structure, easing temperatures across the roof. Without proper venting, the roof can overheat and expand dramatically. Roof materials applied by a Kent roofing professional can actually crack, curl or break down without this venting. Homeowners should understand their vent options and features to keep the roof as strong as possible.
It's a goal to have a balanced system that includes soffit vents. These vents are located behind the roof eave and hidden within the soffit. They act as an incoming ventilation opening. The soffit is sheltered from rain, snow and other weather occurrences, so incoming air is free to move into the home without any problems or internal clogs. Contractors will check these vents and even add more to bring extra air into the structure.
Ridge vents are located along roof peaks, making them perfect for exhaust applications. Attic air is usually warm any time of year, forcing air to rise within the structure. The ridge vents simply allow that warm air to escape, creating balanced air pressure across the roof. The ridge area may need extra vents too, based on a professional's evaluation. Although these vents are more open to the elements, their design makes them less vulnerable to blockages compared to other ventilation areas.

Contractors will still clean out the ridge vents as a standard service, however.
If a home is located in a snowy region, ice damming is possible with poor roof ventilation. Ice dams occur when the roof is warm but the eaves are cold. Snow melts and slides to the eave where it turns into ice. This built up ice melts into the roof, creeping into crevices and staining interiors. Roofers ensure all vents are working properly to create conditions that prevent any ice damming through winter.
Proper ventilation also contributes to less attic condensation. Warm air trapped in the attic is often humid. This moisture condenses on the attic ceiling, creating indoor water leaks. Ventilation allows this humid air to move out of the structure, stopping condensation entirely.
During yearly inspections, contractors can clean out and verify that a roof has all the venting necessary for the structure. Although they're usually hidden from weathering damage, vents can become lodged with debris. Even pests may infiltrate the space. When homeowners keep up with yearly maintenance, roof vents remain in good health for ample breezes between the exterior and interior.
