Choosing The Right Timber Roof Truss Design
In the early days of housing building, roofs that where also built where flat. This was generally because we didn’t know much better and it was also cheaper to build a flat roof. Unfortunately a flat roof is extremely ineffective within our climate, and within a few years of putting up these roofs they began to collapse. Nowadays when we construct houses along with other buildings for the roof we use a timber roof truss.
Roof trusses are frame of kiln-dried timber that is strongly joined together using steal nail plates to create an effective strong supporting shape for your roof. roof trusses will be designed to match your constructions needs. It will be measures and designed to suit your roof extremely accurately to make certain that there is no weakness. A roof truss needs to be accurate as to support your own roofs coverings, plus any additional strength for the weather.
There are three main characteristics which make up a timber roof trusses.
First the timber needs to become lightweight but without the loss of strength, and this is done by using kiln dried and strength rated timber.
The design of a timber roof truss is critical; any changes made without the proceed from a structural engineer can end in a collapse.
The connection of the timber also needs to be precisely done by a good engineer, as any changes within the blots, screws or pegs that hold it together may also decrease its strength and find themselves in a collapse.
Timber roof trusses are really reliable, however sometimes things can fail so you need to watch out for things that could cause failing.
If your truss is exposed to damp over a long time period, even if the timber roofing truss is treated, the damp will affect the wood, leading to strength decrease. This is more common in older building.
Another damp related problem could originate from rot and insect damage. Again this will affect the strength of your truss. This is again common in older buildings in which the ends of the trusses are supported by stone walls.
Joint failure is again common in older structures in which the trusses have been connected by Mortise and Tenon joints, as these can be eaten by woodworm.
A timber roof truss is essential in roof construction, and providing you consult a great company with a great roof trussing reputation, your roof truss will be extremely reliable for years to come.
