Why Roof Ventilation is Important

Installing Attic Vent on Home Roof Replacement Project

Imagine sitting on the roof of your home during a hot summer’s day — you’re already sweating aren’t you? While roofing materials are durable and made to withstand harsh weather conditions they are still affected by extreme heat and UV rays. Luckily, roof ventilation exists and can help keep your roof from developing serious problems.

How Heat Affects Your Home
Think about a 90-degree day in the summer and how hot that can be if you’re outside for an extended period of time. That temperature can reach 150 degrees underneath your roof in the attic space. This heat can shorten the lifespan of roofing materials, cause your A/C unit to work harder, and promote the growth of mildew from condensation in the attic.

Intake Vents
Since roofing materials will heat up to extreme temperatures, vents will need to be installed underneath. Intake vents will be installed at the eaves of the roof, usually in the soffits. These vents will allow air to flow underneath the structure of your roof so the attic will not reach extremely harsh temperatures.

Exhaust Vent
The air that flows through the intake vents will have to be vented back outdoors through exhaust vents. These vents are usually placed towards the top of the roof and can be one of many different types of vents depending on the style and material of your roof. The more vents you have does not translate to a better ventilation system. The proper amount will be needed depending on your specific roof and attic space.

Having proper roof ventilation can help lower the temperature of your attic in the summer, thus protecting your roof from damage.
