When fixing roofing in either very wind graded areas, or known cyclonic regions - fix roof sheets using a suitable cyclonic screw. Designed to withstand much higher wind pressures, the screw fixing also includes a steel cap that shoulders the crest of the sheet thus applying more down pressure to resist the forces of wind whether it 'downforce' or 'upforce'.
