Trusses, roofing Garland TX specialists say, are considered one of the most important parts of a roof, as they support both the underlayment and the roof cover. Here is some useful information they may provide you about the components of the framing system and the purpose each of them serves:
The elements that ensure the connection between the truss system’s lower and upper chords are known as “webbs”. They are of two types, those that connect the chords between them and those that serve for keeping the trusses attached to the walls. Besides their role as connection elements, the webbs also absorb some of the pressure put on the trusses. This is a great benefit, as the chords are prevented from bending.
The section passing over the chords placed at the truss bottom, called “overhangs”, is also very important. This is because it directs precipitations directly into the gutters, successfully avoiding leakages. The chances of humidity appearing and weakening the walls’ resistance are, thanks to the overhangs, significantly reduced.
Another key component of the truss framing system are the chords, those placed at the bottom serving for uniformly distributing tension. The upper chords, Garland roofing professionals say, create the support structure’s top part.
