Expert roofing companies know that a roof is a system, and ventilation is an integral part of it. Ventilation generally keeps the air in the attic cool and dry. Ventilation happens when air flows from the intake vents to exhaust vents. The most common type of exhaust vent is the ridge vent which is found at the intersection of two roof planes called the ridges (hence the name). Intake vents can be found under the soffits, or at the drip edge, or under the shingles at the roof’s edge.
Here are the reasons why proper roof ventilation is important.
Extend the Life of Your Roof
In winter, the warm air trapped in your attic can cause snow to melt quickly then refreeze as ice, leading to the formation of ice dams which can eventually damage your roof. With proper attic ventilation to let the trapped hot air out and insulation to keep warm air from reaching the attic, this can be prevented. Likewise, the lack of proper ventilation in the hot summer months can wear asphalt shingles prematurely because of the extreme heat build-up in the attic.
Also, hot air that condenses in the attic will encourage the growth of mold and mildew. The moisture can also affect the integrity of the plywood decking and your entire roofing eventually. Proper ventilation can prevent all these issues.
Reduce Energy Costs
During summer, a properly vented roof allows heat to escape, thus decreasing the workload on your air conditioners.
