Why is ventilation important? Proper ventilation reduces moisture build-up in your home The average family of four generates approximately 2 to 4 gallons of water vapor each day through activities such as breathing, perspiration, showering, cooking and dishwashing. When moisture vapor remains in a colder/dryer attic, it

The most common places insulation on top of the ceiling of the underlying rooms, resulting in an unconditioned space

The proper ventilation of this space is a critical design and performance consideration. The benefits of proper ventilation include:Ventilation moves heat out

Specific to built-up roofing systems, these challenges can include maintaining the proper asphalt temperature at the point of application, slower cure time of cold-applied adhesives, and increased stiffness of roofing materials.

Read more →The formation of a “tobacco juice” residue, so named for its color, has been widely attributed to the weathering of asphalt roofing (i.e., roof coatings, base and cap sheets, and shingles – to name a few) or the exudation of asphalt fractions from the roofing material. In
Read more →While volatile organic compound (VOC) regulations have tightened over the years, there continue to be compliant adhesive, cement, primer, and coating options available for the installation and maintenance of asphalt roofing systems. Asphalt roofing systems—installed and maintained with VOC-compliant adhesives, cements, primers, and coatings—continue to provide long-term
Read more →Asphalt shingles have been used successfully in cold climates for over one hundred years. Improved application efficiency, and more importantly, enhanced long-term shingle performance, can be achieved by following the cold weather application recommendations outlined below: Be sure to follow the manufacturer’s installation instructions carefully, as most
Read more →ASTM D3462, the Standard Specification for Asphalt Shingles Made from Glass Felt and Surfaced with Mineral Granules, provides that compliance is to be measured at the time of manufacture. Asphalt shingles are complex composite products made by combining materials with significantly different properties. Shingles that are in
