Sigma Exteriors’ Receives Excellence Awards

WAYNE, NJ (03/08) – GAF-Elk, North America’s largest roofing manufacturer, is pleased to announce that Sigma Exteriors of Milwaukee, WI, is one of only fifteen contractors in the country to receive all three of the prestigious GAF-Elk Master Elite Excellence Awards. These coveted industry awards recognize Sigma Exteriors’ dedication to quality roof system installations, and their commitment to continuous improvement and superior customer service.

Most consumers recognize that choosing a roofing contractor can be a confusing and sometimes risky decision. In fact, the Better Business Bureau lists roofing as one of the highest inquiry categories nationwide. As a factory-certified Master Elite™ Contractor, Sigma Exteriors has been carefully pre-screened by GAF-Elk.  In fact, only 2% of the roofing contractors in the country have earned GAF-Elk’s Master Elite status – a distinction that truly sets them apart from the rest, and ensures that Sigma Exteriors is dedicated to helping every customer make their best and safest roofing decision. As a GAF-Elk Master Elite Contractor, they are also dedicated to continuous improvement and training through access to CARE (the Center for the Advancement of Roofing Excellence). CARE is a non-profit educational institute supported by GAF Materials Corporation and dedicated to “changing an industry through excellence in education.”
