Many types of roofing permit the application of a coating or rejuvenator for a variety of reasons, such as increasing solar reflectivity, resisting biological growth, improving impact resistance, or increasing roof life. However, ARMA strongly advises against the field application of any type of coatings or rejuvenators

Read more →Introduction The ASTM D71581 Standard provides a method to classify asphalt shingles for wind resistance by conducting a two-part assessment: (1) determining wind uplift pressure coefficients and (2) determining the uplift resistance of the asphalt shingle sealant strip. The first part involves testing to determine wind uplift

One of the reasons asphalt shingles are a great choice for steep-slope roofing is that they are easy to repair if they become damaged due to unforeseen circumstances, such as impact from windborne debris.
Read more →Asphalt shingles continue to be the most popular choice for residential roof coverings in North America. There are many reasons for their continued dominance in the market, including their ability to provide excellent performance under a wide range of climate conditions. Most homeowners and building owners would
Read more →Asphalt shingles may be used on lower sloped roofs, that is, those with slopes ranging from 2″ per foot (2:12) to less than 4″ per foot (4:12), but only if special procedures are followed. Never apply shingles on roofs with slopes lower than 2″ per foot (2:12).

Read more →Asphalt shingles should not be installed directly on a wood deck roof substrate. Rather, the deck should first be covered by a roofing underlayment. This bulletin describes commonly available types of underlayment products, their respective industry specifications, and useful features and benefits. Always consult local building codes
Read more →Asphalt shingles are manufactured with factory-applied adhesive sealant strips to enhance wind resistance in shingle roof systems. The sealant is typically an asphalt-based adhesive that adheres shingles together after installation. This adhesive strip may be located on the front or back surface of shingles, depending on the
