Regardless if it’s warm or cold out, improper attic ventilation can lead to problems for homeowners. In the winter, improper ventilation can lead to the formation of ice dams. When it’s cold and heat bypasses insulation, it creates warm areas on the roof, melting an area of snow. This leads to dangerous build-ups of ice on colder parts of the roof. Ice dams can be easily eliminated when there is proper attic ventilation.
During the warmer months, heat is absorbed into the attic and can radiate into the living space, causing strain on air conditioners, fans, refrigerators and other appliances, which will be seen in increased energy bills.
To help homeowners learn more about ventilation, in both warm and cold climates, the Asphalt Roofers Manufacturers Association (ARMA) has easily accessible information on everything you need to know about attic ventilation, for the consumer and professional alike.
The Roof Assembly Ventilation Coalition (RAVC) was formed by ARMA in 2008, and is another resource that has invaluable information for roof maintenance, including ventilation on their website: http://www.ravcoalition.org/research.html
With the recently created press room, ARMA offers quick-hitting tip sheets on ventilation and other roof information including roofing reflectivity, BUR multi-ply built-up roofing, green roofing, as well as published articles about the asphaltic roofing industry.
The information is constantly growing and you’ll be able to find ARMA Fast Facts, which are interactive PDFs that serve as Q&A’s and can be downloaded for a presentation or if anybody is interested in answering a specific question.
There are also ARMA MAT Releases that can be used for publications or websites that cover specific roofing subjects in a more in-depth manner, or they can be used like the Fast Facts for the consumer to learn about important roofing information.
