First of all, the owner of the house and the architect of the roof have to sit together and decide what material is to be used to make the trusses. If wood is chosen as the material, it has to be ensured first that the wood is sturdy enough to bear the combined weight of the framing and other layers of the roof, such as the shingles, the sheathing and the insulation layers.
The other problem people often complain about is that the methods of joinery used are not effective enough to eliminate the problems of weak truss joints. Metal, wood, steel and aluminium are the most commonly used materials in the manufacture of roof trusses. But wood will always considered to be the ideal choice of material as it is a warm, natural and very reliable material, and many people consider it to be the symbol of a safe, friendly and congenial environment.
