Eaves have a double course throughout their length using purpose-made eaves tiles for the undercourse. 

Eaves check points

• Twice nail all eaves tiles
  
  
• Supply support for under-eaves course and eaves course tiles using tiling fillet or fascia board
  
  
• Make allowance for strip ventilators fitted to the top of the fascia when calculating the pitch of the eaves course
  
  
• Ensure bottom courses overhang into gutter 50mm
