How To Strengthen A Roof Structure

If you are building trusses it is easy to make part of the roof into a cantilevered extension.

How to strengthen a roof structure.

A cantilever is any structure such as a roof or floor overhang that is braced internally. If you have a stick frame roof there are a few basic techniques that you can use to strengthen your rafters. The bottom horizontal of the triangular truss form which corresponds to the joists in stick framed roofs is known as the lower cord. This open triangle requires bracing and the center vertical brace that supplies this is known as the king stud.

You can strengthen the roof to prevent damage by adding braces to the roof rafters inside your attic. Snow increases the overall weight of your roof adding to the forces acting on your rafters. Laterlite lightweight structural concretes can be used for casting loadbearing roof slabs for further information see structural slabs an beams or to strengthen existing slabs for further information please refer to the section on slab strengthening. To strengthen this frame shorter vertical bracing known as cripples can be added.

Because expanded clay is very strong and has a low self weight it permits longer structural spans and slimmer cross sections in new. This is a fairly basic project that can help protect your roof but consult a structural. The roof structure was unsound and required strengthening something that he could deal with at additional reasonable cost. If your roof is strong enough it can extend beyond the support walls without external bracing.

Strengthening existing roof rafters is a difficult process that often requires professional help. Just make one of the rafter members extend beyond the cross tie.
