Residential Roofing | Roof Vents

Roof Vents are the most overlooked function of a roofing system. A properly ventilated roof can extend the life of your roof system and help with energy bills by removing the hot, moist air that can get trapped in an attic space. However, just the opposite can happen if a roof is poorly ventilated.

The International Building Code (ICC) has taken action on roof vents regarding the types, sizes, and amount of roof vents needed to properly ventilate today’s homes. With contractors using innovative insulation systems the once free air flow has now tightened up dramatically. This is causing moist air that once escaped through cracks and bad seals around windows to be forced up through the walls and into attic or roof area. Which makes the roof vents extremely important to remove that moisture from the home.

Did you know that it is recommended to have only (1) style of roof vent on your roof? Are you aware that roof vents should only be installed at the upper most ridge of the home? Was it known that roof vents are only installed on (1) side of the ridge line? Do all roof vents work the same? Are some roof vents better than others? Should your house be considered for powered roof vents? I heard about Johnson County using the 2012 code book….what does that mean for me? Do I really need twice as many roof vents since the last time I got a new roof?…………..

Wait…..we forgot to mention soffit vents or intake vents. There needs to be a balance between the soffit vents and the roof vents. Roofs should see a full air exchange several times and hour. This process will pull the latent moisture from the home and avoid any mold or unnecessary wood rot to the roof decking or rafters.

Common Problems with Poor Roof Ventilation: curling shingles, blisters on the singles, granule loss, warped sheathing/decking, wood rot, condensation, frozen vapor, water stains, etc.
