All structures must have adequate roof support. Whether you are constructing a residential or commercial building, it is important to select the right roof trusses for your project.

To help you make the choice between timber and steel roof trusses, we have prepared a simple guide. Steel is fast becoming a viable and more cost-effective alternative to traditional timber roof trusses.

Timber trusses

Timber trusses are a very popular type of roofing construction material because wood is generally more affordable than steel. Timber trusses can be installed much faster, saving time and resources.

But if you think that wood is the best roofing material for your home or building then think again. Wood has quite a few negative aspects you need to consider before you decide on this type of truss.

Timber trusses are often used in residential buildings since it seems economical and requires less labor and time to install.
