Roofing Contractor:What are some NRCA guidelines/recommendations for asphalt shingle roof assemblies you’ll be reviewing during your IRE seminar?
Maciek Rupar: We won’t just be addressing NRCA recommendations. There will be discussions of the latest round of asphalt shingle product warranty changes and asphalt shingle recycling. The presentation will provide background information about asphalt shingle performance metrics provided in material and test standards referenced in building codes and specifications. We will review the latest model code changes applicable to asphalt shingle roof assemblies. We will also review NRCA best practices for asphalt shingle fastening, various flashing conditions and attic ventilation, and address related questions.
