Fix it with 12 x 50 Multifix roofing screws through the flashing and the sheet into the ridge purlin, spacing them along the ridge. Overlap the lengths at the ridge joints and seal them so the ridge line is continuous and watertight.

Applications

• Ridge lines on 20 degree pitched corrugated roofs
• Sealing the apex where two sheet slopes meet
• Coastal and high-moisture areas
