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. The tail portion is provided with an adhesive coating and with stiffening means in order to secure the tail portion to and maintain conformity of the tail portion with the profile of the headlap portion of an adjacent tile, and is also provided with corrugations extending across the width thereof. A depending wall portion at the headlap portion of the rigid body portion assists in locating the ventilation tile on a roof batten.
