To make the process somewhat easier, this article will touch on everything you need to know about roof trusses in Cape Town:

Why you should use roof trusses:

Roof trusses are typically used to address expensive, custom building code requirements. There are also many benefits of using trusses, one of which is that installing roof trusses doesn’t require extensive experience. Therefore, it reduces the labour costs, as workers with less experience can be hired for installation. One can also save on building materials. This is especially beneficial if you are renovating or building your house. The use of roof trusses allows for homeowners, or contractors, to use lighter, less expensive materials.

The different types of roof trusses:

While roof trusses come in several different types, there are three common types that tend to be the most popular. These include gangnailed trusses, exposed trusses and Ultraspan lightweight steel trusses.

Gangnailed trusses are roof trusses that use a steel plate with a collection of spikes or nails to ‘weld’ the two pieces of timber together to secure the roof truss by creating a Gang-Nail joint. An exposed truss is exactly what it sounds like. They are roof trusses that are visible in the house or building. Instead of the ceiling being placed below the truss, it is now placed above the truss, leaving it exposed and visible. Finally, the Ultraspan lightweight steel truss is a prefabricated steel roof truss. While the truss is developed using steel, it is still lightweight and compact for economical transportation costs.

The costs involved in utilising roof trusses:

There are several different factors that affect the cost of roof trusses. If one had to breakdown all the costs, one would see that majority of the expense is due to the material used for the truss. However, you can save on costs by having a prefabricated truss installed, as they are far more cost-effective than a customised truss. As mentioned previously, you won’t need to spend as much when it comes to the physical labour and having the truss installed. The main expense is definitely the type of truss you choose to use.

If you are interested in having any roof trusses installed in your home in Cape Town, be sure to make use of a reputable roofing contractor. The only thing worse than going over your budget when renovating is having to hire another contractor to fix the work the previous contractor, who you already paid, has done.
