NB, for more complex roofs, or where you have detailing; you will use more membrane:

  • Ridge lines - on a duo-pitch roof, the membrane overlaps 150mm on both elevations. 
  • Abutments (Wall/Chimneys) - the membrane continues up the vertical a min 75mm. 
  • Valleys- you will utilise more membrane depending on the complexity.

 

It was great! Thank you so much. So easy to use.
