Head tilting fillet installed
This product is designed for the roofing underlay to drain over the head flashing and into the head gutter of the product.
The purpose of the tilting fillet is to support the apron and flashing at the head of the product. Lead used for flashing
must be supported or it will sag over time, allowing water to pool or even to run underneath the tiling to the sides of the
product.

Install the head flashing
Using either the head flashing supplied as part of the flashing kit (if specified), otherwise use 0
.042”
thick flashing lead, fit the head
flashing. The flashing should be at least 11-
3/4”
longer than the external width of the product and should be installed centrally.
