Pvc and polycarbonate sheet roofing come in a variety of profiles, sizes and colors. The quality and the prices can vary extremely. The most common profile is corrugated. The most common lengths are 1800mm, 2400mm, 3000mm and 3600mm and less common, 4200mm, 4800mm, 5400mm and 6000mm. The cover width ranges from 610mm to 760mm and the colours clear, opal, white, solar grey, blue, and green. The quality varies enormously from cheaper pvc sheets up to lifetime guaranteed polycarbonate sheets and the price varies because of this. Warranties vary from zero-long life. Prices vary from $ 10 per square metre to $ 36 per square foot (not including screws or flashings). Sometimes, “cheap” is not the most cost-effective. Brochures are relevant to the type of required sheets is widely available in most stores, it is advisable to read them.
Most types of PVC or polycarbonate manufacturers recommend a 10 degree pitch (approx 1 in 5.7 fall).A smaller area may require additional weatherproofing such as extra flashings or appropriate sealants.
the Garden scissors or a fine toothed saw can be used to cut most sheets. The higher the quality, the easier to cut. Sometimes a carborundum blade on a disk grinder will do the trick, but only one sheet at a time, or it can lead to fusion and welding of sheets.
Pre-drill the holes in the sheets before fixing. The holes should be 8 mm to 10 mm and at least 2 mm larger than the shaft of the screws to allow for expansion and contraction. Ensure that the holes in the high part of the wave. Sometimes it can be easier to put the leaves up and down on the floor and pre-drill. Another tip is to use a stick with a hole in the middle as a guide for the drill.
Suitable screws are available from any suppliers that stock the PVC plastic or polycarbonate roof sheets. If the option is available, the hexagonal head is the most easy to use. Most of the sheets must be fixed at every fourth corrugation and every second corrugation at gutters, ridging and overlaps.
Accessories such as ridge flashings, apron flashings and foam eave fillers are also readily available from any suppliers that stock the PVC plastic or polycarbonate roof sheets.
