INSTALLATION INSTRUCTIONS
Multi Roll
MULTI-PURPOSE VENT
SHED ROOFS (ROOF-TO-WALL)
Wildland Urban Interface Compliant
Vents for roof ventilation are often found in the
soffit. Placing vents in these locations creates a
perfect path for fire to enter the roof structure.
If the vent must be in this location it is better to
place it farther from the wall and closer to the
fascia. The vent can also be placed in the fascia
or near the lower edge of the roof.
