Roof Strut Spacing

The trusses should be a little longer than the exact width to allow for overhang and you will need sufficient trusses to mount across the length.

Roof strut spacing.

Standard roof truss spacing. Typical roof truss. Maximum strut spacing 1 8m. These standards are as follows.

A timber roof truss is a structural framework of timbers designed to bridge the space above a room and to provide support for a roof trusses usually occur at regular intervals linked by longitudinal timbers such as purlins the space between each truss is known as a bay. The spacing between rafters in a given building is part of the engineering calculations that determine the required structure of the roof. Maximum supported roof area 7 0m 2. They should have anti slip blocks where necessary to prevent them sliding horizontally.

4 5 maximum for both sheet and tile roof. Maximum strut spacing 2 1m. The struts are needed in the roof frame to transfer the loads from underpurlins and other beams to the load bearing walls. The roof truss spacing standard is important because eighty percent of new homes are built with standard pre fabricated trusses.

Struts should be adequately supported over studs in timber walls. This means that if you re in charge of repairing or installing roofing trusses you ll be expected to hold to these standards. Rafters have a tendency to flatten under gravity thrusting outwards on the walls. Follow this guide to ensure the spacing and stability of your diy roof trusses.
