Chesapeake Roofers: Article About Rooftop Ventilation Components
The main concerns regarding rooftops usually center around leak protection. Although this concept is critical to any roof's functionality, homeowners should also be aware of proper ventilation. The home's interior may have a comfortable climate, but the attic heats up and cools down with extreme temperatures. All of these excessive temperatures directly impact the roof's lifespan. Proper ventilation components serviced by Chesapeake roofers will keep a roof in top shape for decades at a time.
The most common rooftop ventilation components are the soffit and ridge vents. When homeowners look up at their eaves from ground level, they should see subtle vents hidden in this alcove. These soffit vents are designed to incorporate incoming air as it strikes the structure each day. Exhaust vents for that air are located at the roof's peak or ridge. These ridge vents are more difficult to see from the ground, but they allow warm air from the structure to release into the atmosphere.
Connecting the soffit and ridge vents is a rooftop shaft. This passageway is located beneath the roof decking and above the attic. Each structure has unique construction around the passageway, making it a challenge to find for most residents.

This channel must remain clear at all times, so air can move unimpeded between the soffit and the ridge. Positive air flow keeps the roof decking cooler.
Homeowners won't be able to see ridge vents in most cases because they're strategically covered with caps. Ridge caps create a protected area around these vents, preventing any rains from leaking into the ventilation shaft. These caps are also designed for aesthetic purposes too. Their umbrella effect shelters the vents and makes the entire rooftop appear as one continuous surface.
The best ventilation care can still leave the home with poor air circulation, so homeowners can choose to add rooftop turbine vents. These domed vents aren't static, but actually spin in place. Their action forces air out of the attic. With less warm air trapped in the structure, the soffit and ridge vents can keep up with steady rooftop temperatures. As a result, shingles and underlayment don't have to succumb to a short lifespan with extreme hot and cold conditions.
To further enhance the structure, hire contractors to install blown in insulation within the attic. Along with regulating temperatures inside the home, insulation also benefits the rooftop. Shingles and underlayment will withstand extreme temperatures with the moderating help of insulation and proper ventilation. Reputable contractors verify these components with each yearly service call.
