CertainTeed Master Shingle Applicator

The Wizard test is optional.  It is therefore only attempted by a small group of dedicated individuals.  This certificate is rare and prestigious. 

Both tests are based on the CertainTeed Shingle Applicator’s Manual.  This publication discusses the complex requirements and recommendations for the installation of a high-quality shingle roof system.  Renewal is required every two years by examining the updated information contained in the current addition of the CertainTeed Shingle Applicator’s Manual

Topics covered include the specific installation instructions for CertainTeed Shingles, workmanship, estimating, roof ventilation, shingle underlayment, flashing specifications, and more.
