- It is not recommended to install partial areas of roof with Wedge-It®, as this will cause bumps in the roof. It is recommended to install entire sides and sections with Wedge-It®.
- It is recommended to paint the front edge of the first course of Wedge-it to avoid seeing this course from over the riser metal. Roofmaster™ Paint is recommended.
- While Wedge-It® can double the load capacity of some lite-weight roof tiles and increase the walkability of the roof, there is no guarantee against some breakage of tile. Wedge-It® accepts no responsibility if manufacturer instructions are not followed for installation of Wedge-It® and roof tile.
