3 Vital Tips for Novice Installers When Working With Prefabricated Roof Trusses

More and more homes are now using prefabricated roof trusses for framing roofs. Trusses provide a flexible, simple and cost-effective roofing option for prospective homeowners. Due to their extended span, trusses are ideal when homeowners desire for an open floor plan. Furthermore, the structures can increase the interior height of a house without necessarily raising the height of the structure. Because of the prefabrication process, on-site installation of roof trusses reduces labour costs. Here are some tips for novice installers when working with prefabricated roof trusses.    

Storage -- One major challenge that construction contractors face when dealing with prefabricated roof trusses is storage. Ensure that you prepare a flat surface to store the roof trusses. For a sloping terrain, it is recommended that you hoist the truss packs straight on the wall as they await installation. Uneven storage surface can lead to truss damage in the form of bents and twists. For long-term storage, protect the trusses from weather elements by covering them with sheeting or cloth, but leave the ends open for improved ventilation. Before installation, roofers must inspect the truss packs to ensure that there is no damage. In case you spot any defects, report the matter to the truss supplier. A good roof truss supplier will conduct an independent inspection and give a written consent to use the trusses.

Installation -- The method of installing roof trusses should be consistent with architectural specifications and plans. Therefore, the installer should familiarise themselves with such plans and not deviate from any specifications. The method of installing trusses, usually by machines or by hand, depends on factors such as availability of installation equipment, the span of trusses and height above ground. In this sense, contractors must be furnished with all the relevant information before beginning installation. The report includes truss placement plans, design drawings, and safety precautions during installation.

Internal wall brackets -- A good rule of thumb is to install trusses with precise clearance from interior walls in mind. Roof trusses bend when they encounter heavy loads, and thus, inner wall brackets help to reinforce the structures and enable vertical movements. There are several types of truss brackets for installing on interior walls. Use brackets that have been recommended by the truss manufacturer to avoid any weak points when fitting the trusses.  Also, the brackets should be installed correctly following the supplier's manual to allow truss movement. In this sense, avoid punching or driving nails entirely into the brackets.
