Proper Ventilation is one of the most important aspects to home construction, yet attic ventilation is often overlooked or dropped from contracts to save costs and time. Inadequate attic ventilation can lead to numerous problems, roof failure being one of the most common and also the most damaging.


It can be difficult for homeowners to understand building science, it takes time, and often the contractors or companies will abandon critical components necessary to both the lifetime of a roof and the health of a customer (mold).

Proper ventilation allows your home to "breath". Warm moist air rises and without adequate means of escape will build up as "condensation" causing serious problems in your roof and attic including "mold" and "mildew". Heat will also build up in the attic in excess of 165 degrees, "baking" the roofing material from underneath leading to premature aging and failure of the roofing material.

Unfortunately homeowners can also experience a larger setback, paying for a new roof because the manufacturer declares the warranty null and void after inspecting an improperly ventilated roof plus a bad installation. A manufacturers warranty is greatly "reduced" or "void" if the roof is not ventilated properly. As a result, homeowners have to replace roofs or do major repairs that should have another 10-20 years remaining on the warranty. This is why it is so important to choose a reliable roofing company, that knows all these aspects of your roof.

Most homeowners are unaware that attic ventilation is critical to the life of their roof and may not know to question the specifics of the ventilation process. Ventilation needs to be both at the eaves, underneath, and at the peak of the roof for proper "intake" and "exhaust" of excess heat and moisture. However every roof is different and ventilation formulas are used to alleviate "guessing" and are based on the square footage of the attic, the type and shape of the attic and vent sizes. A qualified Roofing Contractor should know all the specifics.


When homeowners are considering a roof replacement they should always have their roof inspected for proper attic ventilate. An inspection can save you thousands of dollars in the long run. It will extend the life of your roof and possibly reduce risk of health problems from attic mold and mildew.
