Abstract: A roof tile construction includes a ventilation tile having pliable portions provided by a membrane of PVC (polyvinyl chloride) which is readily deformable to complement the shapes and configurations of adjacent roof tiles, whereby gaps between the headlap, side-lock and tail portions of tiles immediately adjacent the ventilation tile are substantially closed. The ventilation tile also includes a rigid body portion for supporting the membrane, the body portion being generally of planar configuration and being provided with adapter means for accommodating ventilation means such as a ventilation cap, or a soil pipe. The membrane is also of generally planar configuration and includes a headlap portion, oppositely disposed side-lock portions and a tail portion which extends beyond the rigid body portion.
