FASTENING

To ensure a secure roof, we recommend the use of self-drilling screws 45mm or 55mm length. Roofing nail of twisted shank with neo-prene washer can also be used. Roofing sheets are to be fasten through the upper crest, holes for the screws are to be pre-drilled. We would recommend the use of silicone sealant (non-acidic) to ensure water tightness at screw points.
