The Value of Working with a GAF Certified Contractor
When you choose our GAF certified services, you’re investing in peace of mind that extends far beyond the initial installation. GAF, North America’s largest roofing manufacturer, produces approximately one in four asphalt shingles installed in the United States, controlling roughly 25% of the residential roofing market. This market dominance isn’t accidental—it’s the result of decades of innovation, quality control, and product development that has set industry benchmarks. As a certified installer, we have direct access to GAF’s complete product line, including their Designer Lifetime Shingles, Timberline HDZ shingles, and advanced roofing system components that work together to provide comprehensive protection for your home.
The certification enables us to offer enhanced warranty options that non-certified contractors simply cannot provide. These warranties can include coverage for both materials and workmanship, with some extending up to 50 years on materials and 25 years on workmanship when using GAF’s complete roofing system. This level of protection represents a significant advantage for homeowners, as studies show that proper installation accounts for approximately 40% of a roof’s long-term performance. Our certification ensures that every installation follows GAF’s strict Master Elite installation guidelines, which have been developed through extensive research and field testing across millions of installations nationwide.
Technical Excellence and Installation Standards
Our GAF certification requires us to maintain exceptional technical proficiency in all aspects of roofing system installation. We follow a comprehensive checklist that includes proper deck preparation, ice and water shield application in vulnerable areas, correct underlayment installation, precise shingle alignment, and optimal ventilation calculations based on your home’s specific requirements. Each component plays a crucial role in the overall system performance, and our certified installers understand how these elements work together to create a weatherproof barrier that protects your home for decades.
