Intake and exhaust vents ensure a healthy, long-lasting roof and a comfortable indoor environment while reducing energy costs. Roof leak repair contractor Genesis Roofing explains the importance of these components and their significant roles in maintaining the longevity and performance of residential roofing systems.
The Basics of Roof Ventilation
The concept of roof ventilation is straightforward—allow air to flow through the attic to minimize the buildup of heat and moisture. It is usually done using mechanical or natural means. The former utilizes a power source while the latter takes advantage of the stack and wind effects to facilitate air circulation.
Roof ventilation systems aren’t the same in every home. Implementing them during residential roof replacement takes several factors into account, including regional climate, local building codes and roof and ceiling design. Two types of roof vents are used:
Intake vents – These are found at the eaves under the soffit. They allow cool air to enter the attic.
Exhaust vents – These are commonly found at the intersection between two roof planes. They allow hot, moist air from inside the attic to escape.
The Importance of Roof Vents
One of the many benefits of roof vents is that they help extend the roof’s lifespan. As long as there are no blockages, heat and moisture can’t accumulate inside the attic. This helps prevent issues such as shingle damage and mold and rot buildup.
Proper ventilation also helps reduce energy costs. If your roof is well-vented, the heat won’t radiate down to your indoor spaces. Your air conditioning system, in turn, doesn’t have to work harder just to keep the inside of your home cool and comfortable. In other words, HVAC systems that run less mean a lower electricity bill.
