ScanRoof, a scalloped tile with a Northern European flair, is an easy-to-install metal roof panel. The panels are structural, practical and economically efficient for any project. ScanRoof is the ideal roof system to stand up against Mother Nature’s storms, typhoons, hurricanes, damaging winds and driving rains. The panel is installed horizontally, from eave to ridge. ScanRoof has a 2” high integral Z purlin allowing for air flow between the panel and substrate. It is lightweight, allowing installation over an existing roof without the need for tear-off and disposal*. Typical applications for ScanRoof are commercial and residential roofing with a recommended minimum slope of 3:12. It also is suitable for mansards.
