Understanding the Importance of roof ventilation
Ventilation prevents the attic from overheating in the summer
Adequate ventilation is essential in any home, and the roof is no exception. Such provisions protect the roof's structural integrity and help it last longer.
Here is a look at why roof ventilation matters.
Why ventilate the roof
Ventilation prevents the attic from overheating in the summer. As a result, the HVAC system doesn't need to work as hard. On the other hand, it keeps the heat inside during winter, so the system doesn't need to waste energy producing more heat.
A well-ventilated roof also reduces condensation in the attic and under the roof. Less dampness means mold is less likely to grow, and wood is less likely to rot.
Components
The roof ventilation system consists of intake vents and exhaust vents. The former lets fresh air into the attic to circulate and vent out the moisture. Usually, these vents sit in soffits or eaves. The latter releases hot and damp air from the attic into the outside world. Typically, these vents are situated near the roof's peak.
What is ventilation good for
The house benefits greatly if the air can circulate freely under the roof. The air conditioning system doesn't have to work so hard, translating into lower energy costs and bills. The roof lasts longer when mold and rot aren't a problem.
Furthermore, it protects the roof from heat damage. No less significant is the general comfort inside the house due to more stable attic temperatures.
How to know the ventilation isn't adequate
Conversely, inadequate ventilation can make the wooden boards under the roof rot, forcing the HVAC to work harder and increasing energy costs. Look for ice dams in winter to see if the roof releases enough air outside. Ice dams indicate uneven roof temperatures. Also, if energy bills are higher than usual due to overworked HVAC, improper roof ventilation could be to blame.
Finally, mold and mildew in the attic are linked to trapped moisture, likely because of improper ventilation.
How to improve ventilation
Check the state of roof ventilation and see if it needs any upgrades or if there is anything to fix. Professionals can inspect the roof and clean and fix the vents if necessary. It isn't enough to have vents installed. Keep in mind that the intake and exhaust vents must be balanced for the ventilation to be effective.
Professional installation
Hire professionals to install vents if they aren't installed or need replacement or upgrade. Having professional assistance is better than attempting a DIY fix. The experts can also maintain the vents to keep them working correctly.
