Minimum Roof Pitch

For roofs with continuous sheets and no end laps the minimum roof pitch is 1º (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 5º and 15º and 150mm above 15º. For walls allow maximum end laps of 100mm. End laps in roofs of less than 5º 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.

Length

Metroll can supply Metlok 500 sheeting up to a maximum length of 35 meters depending on availability of delivery. Lengths to be manufactured by Metroll should be site measurements, not those taken off plans.
