How to Install Metal Corrugated Roofing Sheets
Step 1: Prepare Your Roof Structure
Ensure the roof frame is level & secure before installation.
Check for proper support, especially on low-pitch roofs (minimum 10 degrees).
Step 2: Position & Overlap the Sheets
Overlap each sheet by one corrugation for a tight seal.
Work from left to right, aligning the sheets to withstand wind pressure.
Step 3: Fixing the Sheets
Use 65mm screws with Baz washers at every third corrugation.
Attach the sheets to purlins at 600mm centres for optimal support.
Step 4: Secure with Flashings & Final Touches
Install ridge caps, barge boards, and flashings for a leak-proof finish.
Use a high-performance sealant to close any small gaps.
