Roof framing has evolved so much over the last few decades. While we used to rely on rafters to provide framing for our roofs, more and more people are finding that a roof truss system is not only more economical but also faster and simpler as part of the whole process.
Roof framing ranges from the simplicity of pre-fab roof trusses as to the complexity of assembling a complex roof design entirely from scratch. This article will cover only the basic truss construction, as this is the recommended procedure for novice builders. Trusses are a pre-built series of structural members designed to bear the full load of the roof, distributing weight along the outside walls.
Our job for the roof manufacturing process is to make things as easy as possible, and as such,
the structural members are quite often 2×4’s or 2×6’s. These trusses are ordered through your supplier (possibly us) and are built-in special factories over to the individual specifications.
When ordering with us, you can rest assured that all roof trusses are made to specification, however, you or a professional you have on the site should have a check to make sure that it is up to standard.
We take the following considerations into account when designing our roof trusses.
- Size of rafters.
- The spacing of racers.
- The length of the overhang.
- The location and size of ceiling joists.
- The size of the ridge beam, and also other bearing beams.
- Load weight.
In roof production and installation, one of the most common mistakes is ordering inaccurate trusses, not accounting for overhang and rake rafters. Placing the rafter on the wrong side of the layout mark. This is also a mistake when accounting for feature trusses.
When you go with a reputable company like Aber Roof Truss, the potential of these mistakes occurring is minimised, as well as having systems and procedures in place that make sure that everything is produced to a high standard.
Once the roof is installed, it will have to be sheathed. It’s true that this part of the job isn’t particularly cheap, however, there are many great roofing North Wales companies in the local area who will do a sterling job when it comes to roofing.
Common mistakes that are made here are:
- Not staggering the seams of the sheathing, aligning sheathing with the edge of a rood rather than perpendicular to the rafters/
- Attaching the sheathing the wrong side up.
- Inadequate nailing.
- Panels not meeting in the centre of a truss or rafter.
