Z Construction Is El Reno, Oklahoma's only Manufacturer Certified Roofing Contractor.
John Zawlocki of Z Construction has earned CertainTeed's Master Shingle Applicator Wizard Certification having passed both the CertainTeed Shingle
Applicator's Manual test and very challenging Wizard test on the first attempt. The Wizard test is optional. 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 edition of the shingle Applicator's Manual. Topics covered include the specific installation instructions for CertainTeed Shingles, workmanship, estimating, shingle underlayment, flashing specifications, ventilation and more. Including the Grand Manor and Carriage House Shingles.
Tom Smith President of CertainTeed Roofing has endorsed this certification through January 26, 2020.
