Plate level is the timber plate which is going to hold the roof structure including the roof joists hips and roof rafters.
Where a pitched roof abuts the wall at an angle a stepped cavity tray linked to a stepped flashing should be used.
Drill holes at these marks to allow a 6 nail to be driven through the wall plate into the joists.
Fixings used to connect the roof structure to the wall plate should be specified according to the roof construction and exposure of the site.
Stepped flashings should be cut from a strip at least 150mm wide.
Balcony abuts a wall.
Rafter sizes tend to differ massively and will normally be determined by finding out the length from the wall plate to the ridges as well as the type of roof covering that is being used.
