Metro Roofing
Developed by some of New Zealand’s most accomplished roofing professionals who have been actively involved in the roofing industry for over quarter of a century, Maxispan® is a strong and aesthetically pleasing high rib roofing and cladding profile. The profile incorporates a number of innovative practical design features and provides significant advantages to building designers Applications
  • Convex ribs provide strength and water run-off away from the fixings
  • Twin capillary breaks on the lap
  • Purpose designed leg provides support to the underlap
  • Installers feet fit neatly in the pan avoiding damage to the ribs
  • Can be “reverse run” and the swage removed for wall cladding application
  • Lap can be altered in the reverse run process to ensure improved aesthetics and water tightness (.55 BMT recommended)
  • High volume water carrying capacity
  • Wide cover reduces installation time
  • Superior spanning at low pitch
  • Supported by Wind and Concentrated Load Span Design graphs derived from extensive industry test rig trials
Roof PitchThe minimum pitch for Maxispan® is 3°
(approximately 1 in 20).

Our new roof was completed today. All up it has taken just one and and half days to do the job. We think the job is excellent. Our home looks so much the better with a new shiny roof. Your crew worked very hard to finish the job in such a short time...
