Core 4 Technology

Flexible Bendable Pliable
StormMaster® shingles with FlexCore bend and ex when others
crack and tear. Their elasticity is what makes them stronger in two ways:
BETTER TEAR STRENGTH: Because these shingles can bend and ex, they exceed
the industrys standard tear strength requirement by 50 percent. Even in cold weather
installation, they are more likely to withstand tearing and cracking that can lead to
blow-os, leaks, and compromised long-term roof stability.
FLATTER INSTALLATION: Shingles that don’t lay at won’t properly seal during
installation. FlexCore technology makes shingles more pliable, which means they lay atter,
seal properly, and provide greater protection for your home.
