Sierra Roofing Systems takes great pride in the fact that we are certified by a very select group of roofing material manufacturers. Many roofers will tell customers that certification is unimportant. We fervently believe that certification is vitally important. 65% of new roofs that fail, do so due to improper installation. Our certifications quarantee that we will install your new roof properly. Another benefit of being certified is that the manufacturers monitor our Worker’s Compensation and Liability Insurance - so that you know we actually have them... unlike many roofing contractors in California. Most of the certification programs require that a contractor be in business for a minimum of five (5) years, have indepth knowledge of the manufacturer's products, and demonstrate expert ability when installing the products. We hope you agree that certifications are important, and choose to read more.
