Why does manufacturer training matter for roofing installation?

Short Answer

Manufacturer training matters because roofing and exterior products have specific installation requirements that vary by manufacturer and product line. A contractor who has been trained by the manufacturer understands these specific requirements — nailing patterns, underlayment specifications, flashing methods, ventilation requirements — and can install the product in a way that meets the manufacturer's standards for warranty coverage and performance. Without manufacturer training, a contractor may install a product using generic methods that don't meet the manufacturer's specific requirements.

Detailed Explanation

Roofing and exterior products are not all installed the same way. Each manufacturer has specific installation instructions for their products, and these instructions can vary by product line within the same manufacturer. For example, different shingle lines may have different nailing patterns, different underlayment requirements, and different wind-rating requirements that depend on the installation method. A contractor who has been trained by the manufacturer — through a certification program like Owens Corning Platinum Preferred, CertainTeed SidingMaster PREMIER, or VELUX Certified Installer — has learned the manufacturer's specific installation methods and requirements. This training matters for several reasons: warranty compliance — the manufacturer's warranty assumes the product was installed according to their instructions. If it wasn't, the warranty may be voided. Performance — products installed according to the manufacturer's methods perform as designed. Products installed with generic or incorrect methods may fail prematurely. Safety — some installation methods are specified for safety reasons, such as wind-resistance requirements. Consistency — manufacturer training ensures that the contractor's crews install products consistently across projects, reducing the risk of installation errors. A contractor who has not received manufacturer training may install products using generic methods that are 'close enough' but don't meet the specific requirements. This can result in warranty issues, performance problems, and premature failure. This is why manufacturer certification — which includes training — is an important factor in contractor selection.

Questions to Ask Your Contractor

• ?What manufacturer training have your crews received?
• ?Are you certified by the manufacturers whose products you install?
