VALLEY FORGE, Pa. — CertainTeed Corporation is offering updates to its comprehensive shingle roofing installation manual, the Shingle Applicator’s Manual (SAM). Written for roofing professionals, SAM is a fully illustrated manual, with the most-up-to-date shingle roofing installation instructions and tips.

The ninth edition SAM contains new information on ventilation, Flintlastic SA roof systems and tips for installing WinterGuard over existing waterproofing shingle underlayments. It also contains new and updated flashing diagrams, an alternative method to install open metal valleys with laminate shingles, and a newly approved method for installing Landmark Series shingles. The updated manual also reflects product line revisions, including the addition of Swiftstart starter shingles.

“This manual is the roofing industry’s most authoritative guide to proper steep-slope roof system installation,” said Jay Butch, senior marketing manager of contractor programs for CertainTeed Roofing.

Contractors can use SAM as a training tool for installers, a reference guide and a sales aid to demonstrate to customers that they install a roof “according to the book.” In addition, contractors can earn the Master Shingle Applicator qualification from CertainTeed when they pass the test associated with SAM.

SAM is published in both English and Spanish, and a companion DVD is available in both languages. For more information, call 800-233-8990.
