The wooden structure of the roof occupies a large part in the construction structure, so you need to choose wood for the roof carefully. Wood for roof construction can be bought in the form of ready-made structures, after cutting rails and boards in cubic meters. Regardless of the type of purchase, builders advise buying ten percent more wood than your building plan says, because projects often don’t account for waste and undercutting materials. If you need to buy boards, slats and beams, specifying the number of boards in cubic meters, it is best to prepare the necessary wood for building a roof on the construction site. But this can lead to some risks: firstly, wood waste will increase, and secondly, it is necessary to ensure a good quality of sawing, impregnating and polishing wood.
Buying a pre-prepared cut wood billet will reduce your cash costs and waste, reduce the construction time of buildings – at the construction site, the builder will only need to connect the finished structural elements from the roof. But to buy a finished tree for a roof, you need to know exactly the number and dimensions of all the necessary elements. This specific roof design is not provided with the construction project – but it can be ordered from the contractor or designer.
Buying ready-made building structures will allow you to speed up the construction of the roof up to three days. Assembled at the factory and factory building trusses are usually of higher quality and more expensive than simple cubic meters of wood. Before buying ready-made building trusses, the seller gives his measurer for the construction, who specifies the distance between the walls of the house for compliance with the plan.
