Face level for a bituminous tile

The face level for a roof in turn has the G-shaped design and is subject to fastening at lateral end faces of roofing slopes.
Overlapping of an end face the face level bears double function:

1. Protects an obreshetka from blotting.
2. Protects a roofing flooring from wind loading (does not allow to break roofs to strong flaws).

Owing to the last the face level also received the second name – a wind level.
