How do you lay big 6 roofing sheets?

To lay big 6 roofing sheets, start by ensuring the roof structure is clean and free of debris. Align the first sheet at the eaves, overlapping it with the previous sheet by at least 150mm to prevent water ingress. Secure the sheets using appropriate fasteners, typically at the ridges and in the valleys, ensuring they are spaced evenly. Finally, check for proper alignment and level before proceeding with additional sheets.
