Extensions

Roof Trusses vs custom build

Anonymous user 23/02/2024 - 2.42 PM

I have a first floor extension with a flat roof and I want to build a second storey, my architect has produced plans with the roof design being custom built on site, the builder, very reputable local firm has proposed using prefab roof trusses which will save on cost. Is there anything that I should be aware of / worried by? The main concern appears to be the structural integrity of the floor and whether the walls will support the construction how would having a purpose bulit roof mitigate this concern?

Are you a tradesperson and able to answer this question?

In reply to your question, it would depend on why the architect has asked for a traditional roof build, generally speaking roof trusses are made out of a smaller timber section than traditional so therfore will be lighter and put less weight on the existing structure due to the 600mm spacings between ( a traditional roof has 450mm spacings so more timber) all trusses come with a bracing plan so therfore are easier and cheaper than a traditional roof as they can be installed in a day or so compared with a week at least for a trational roof.I would consult your architect and building control before you decide as the building regulations would need to be changed to a truss roof.
