If you are building a new house or renovating an old roofing structure, you should be cautious when installing the supporting trusses. The choice will determine the ability of the frames to support the roofing material and withstand the wind load. Also, this element will affect roof durability after years of exposure to adverse weather and other structural stresses. If you are installing timber trusses for the first time, consider these practical tips for optimal success.
Choose Larger Timber for Trusses
Trusses can be made using timber members of different dimensions. It is important to select the right lumber sizes to match the needs of your home. In general, if you are building a small structure such as a shed or carport, you can utilise thin framing wood. However, house roofs are much wider. The broad structure has to bear more weight because of the increased units of roof tiles, shingles or panels. Moreover, the surface area will have to handle more wind loads. Therefore, you should choose timber sizes that match your needs. If your roof is large, invest in bigger truss members for ideal roof performance and longevity.
Install Strong Connectors
When building the roofing framing, you should make sure that the roofing trusses have resilient connectors. If the fasteners between the lumber are not robust enough, the constant stress on the roof could lead to untimely collapse. Under ideal circumstances, your trusses should have flat steel connectors to bind the timber. These products are sturdy and will not experience premature distortion. You should ensure that the fasteners are galvanised to prevent premature failure due to corrosion. If you are building the roof framing on the site, you should be careful not to substitute the connectors with screws. This choice could lead to premature failure.
Connect the Trusses Using Bracing
You should utilise a bracing system when installing the roof trusses over your house. The braces will connect the trusses and keep them secure with the appropriate gaps in between until you complete the installation work. In general, these roofing members are heavyweight units, so they are difficult to keep in place without structural support. If you attempt to install without external bracing, the framework might not perform as expected and your workers might sustain injury. Therefore, you should ensure that you have braces to stabilise the trusses until the structures are correctly installed.
Choosing the right trusses for your residential structure can be challenging. Consult a roof truss supplier for more information.
