1. Ensure the roof truss has a minimum slope of 50.
2. Install purlins with 300mm spacing between the first and second purlins and 600-800mm spacing for the remaining purlins.
3. Lay roofing sheets starting from the eave and working toward the ridge.
4. Align the first sheet squarely with the roof edge before fastening.
5. Maintain a minimum of 150mm end overlap.
6. Provide a side overlap of at least one and a half corrugations.
7. Select the appropriate Tekscrew based on the purlins material, whether wood or metal.
8. Fasten sheets at the recommended locations without over tightening the screws.
9. Install ridge rolls and flashings, ensuring proper overlaps to prevent water leakage.
10. Remove all metal fillings, loose screws, and debris after installation.
