Grayco Roofing Consultants Air Barrier Association of America INC. Member CertificateGrayco Roofing Consultants is now a professional member of the Air Barrier Association of America.  ABAA is a national organization that patrols the air barrier industry for compliance with minimum standards, codes and related requirements.

Air barriers have become an integral part of a healthy, fully functional facility, and education and training have evolved significantly in recent years. David Cook, RRO, CIT, our resident in-house building envelope expert, has been trained by ABAA in site quality control audits through prescribed courses. He has been performing quality assurance of air barrier audits since 2015. Let us assist you with understanding the importance of air barrier design, installation and the QA/QC process, among other critical elements of the building envelope.

Grayco has made the move toward consulting for the entire building envelope in addition to the full spectrum of roof consulting already offered by the firm. As a result, Grayco is updating their list of capabilities and offerings, and this important information will be posted to the company website in the near future.
