WHY CONSIDER IT
Product strengths.
Lightweight roof covering
Low-mass sheets or tiles can simplify handling and reduce the load imposed by the roof covering, subject to structural review.
System-specific laps
Side laps, end laps and fixing locations vary with pitch and exposure and should be set from current manufacturer guidance.
Coordinated accessories
Ridges, verges, apron details and compatible fasteners complete the weathering path around the roof perimeter.
