This proprietary design assembly protects the part of the house most vulnerable to fire. The Flame Deflectorâ„¢ assembly also dresses up the house with its shape and limestone look. Because it replaces the soffit, fascia, and frieze assembly on the house, it is actually cheaper and maintenance-free compared to traditional materials. In areas susceptible to hurricanes or tornadoes, this assembly also serves to protect the roof from being torn off by intense winds.
