If you are planning on building a roof with timber trusses, you must engage a qualified contractor for the installation of this framework. Roof trusses are designed to support the roofing materials, ensuring protection of the interior space. If the framework is not built properly, it might not be able to support the weight of your metal panels or tiles. Also, the truss system might crumble under the pressure exerted by environmental wind and inclement weather. In addition to hiring an experienced contractor, you should use the practical tips below to promote optimal roof truss performance.

Do Not Cut the Trusses

Prefabricated timber trusses are built by experienced engineers after careful consideration of the design, dimensions and materials required for maximum strength. If you make an unauthorised alteration, you will damage the structural resilience of the roofing framework. Therefore, you should not plan on cutting the units after purchase. If you feel that this form of modification is necessary, you should talk to a structural engineer or your truss fabricator.

Plan for Excess Weight

If a lot of weight or pressure is exerted on trusses, the unit can spread and lose its structural integrity. Also, the spread of the trusses can cause damage to the building walls. If this is a real concern for your building work, you should think about using truss ties. These rafter ties are pieces of wood which are built to link the opposite supports of the truss, preventing the spread. Typically, the ties are not required except during the construction of small sheds and garages with onsite built trusses.

Brace the Truss

Timber trusses are lighter than steel alternatives. However, these roofing members are still quite heavy. If they are handled poorly, they could cause extensive property damage and even personal injuries. Therefore, you should make sure that you have a suitable truss bracing system before commissioning roof construction. The system will ensure that the units remain upright until they are built. Also, you can use the braces to ensure that the roofing trusses are properly spaced.

Protect the Connections

Your roof trusses will have multiple connection points. These connections are essential for the integrity of your roofing framework. If the fastening agents such as glue, bolts or metal plates are damaged, the roofing framework will no longer be stable. Therefore, you should prevent the damage of these ponts when handling the trusses during construction. You should be careful not to cut or otherwise interfere with these points without the approval of a professional.
