Marley Undertile Membrane or Radiant Barrier is recommended at all pitches in exposed and coastal areas. The minimum pitch and minimum headlap must not be reduced under any circumstance. It is always better to raise the safety factor of the roof by adding a full course of tiles and increasing the tile headlap evenly on the rafter length. In exposed areas the tile headlap may be increased, but greater lap is not as effective as a steeper pitch. Due to natural variations in the raw materials and the occasional occurrence of efflorescence on concrete products, absolute colour uniformity on the roof cannot be guaranteed with Standard Through colour tiles. All tiling and fixing to comply with SANS 10062 and 10400L code of practice.
