Minimum roof pitch
For roofs with continuous sheets and no end laps the minimum roof pitch is 1° (1 to 60) to prevent ponding from occurring this minimum pitch must be adhered to at all points of the roof.
For roofs with end laps the minimum lap is 200mm for pitches between 5° and 15° and 150mm above 15°. For walls allow maximum end laps of 100mm.
End laps in roofs of less than 5° should be sealed with a suitable sealant. The sealant should be in two runs; one at the low end of the lap to prevent moisture being drawn in by capillary action. The other should be at the high end of the lap to prevent condensation that may form under the top sheet, from draining down the underside and entering the lap.
Sheets should be laid in the opposite direction to the prevailing weather.
