Revised November 2023 By Asphalt Roofing Manufacturers Association (ARMA) Attics are often overlooked and may be viewed by homeowners as just another place to store excess boxes of clothes and decorations. This is a mistake because, if not properly ventilated, an attic space can negatively affect energy

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
Read more →Attic ventilation is:Attic ventilation is the flow of outside air through the space at the underside of the deck of an asphalt shingle roof system. 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
