Roser is a premier solution in areas that have a potential for wildfires due to its class A fire rating. The steel core and 3M granules are non-combustible materials which means that the Stone Coated Steel System is an exceptional first line of defense for burning cinders or other fire-causing materials. The interlocking profile does not allow embers to fall through any section of the roof, and acts as a single, non-permeable unit.
Collapsing roofs during a fire are a significant safety concern. Most types of roofs will fall in sections from weight and lack of interconnectedness. Every section of a Roser Roof is interlocked as as a single, lightweight unit.
The air gap between the roofing panels and the roof underlayment dissipates heat by creating a convection current. This is not only a great energy saver during hot or cold periods but is the reason for the effectiveness of the Roser system in an event of an external fire.
