While many roofers tell clients that certification is unimportant, we at Sierra Roofing strongly believe in the gravity of certification. Sixty-five percent of new roofs that fail are a result of improper installation. Our certifications guarantee that we will install your roof without error. Another benefit of being certified is that manufacturers monitor Worker's Compensation and Liability Insurance. Unlike numerous roofing contractors in California, you can be certain that we hold these designations. A majority of the certification programs require that a contractor be in business for a minimum of five years, have in depth knowledge of the manufacturer's products, and demonstrate expert ability when installing the products. Certifications are undoubtedly a fantastic asset; if you would like more information on the subject, please references the links below.
