FLEX or STORM?
FLEX is rubberized all the way through, which keeps it flexible. STORM adds a tough backing layer. Both are Class 4. Owens Corning's literature notes that the Class 4 system rating depends on using its impact-rated hip and ridge, so we always install the matched accessories. Texas insurers must offer a premium credit for UL 2218 impact-rated roofs, but each company sets its own amount, and Class 4 earns the largest. We can't promise a discount; ask your insurer for their figure in writing. After a qualifying install we fill out TDI Form PC068 for you.
Getting the full warranty
Every major shingle maker ties its best warranty to its own accessories: starter strip, hip and ridge, underlayment and ventilation. We install the matched system to the manufacturer's instructions, photograph the components, and give you the paperwork. Every inspection comes with a free digital photo report, so you see what we see.
