New beams would be required.
Strengthen roof trusses loft conversion.
For small loft conversions this can be done by installing additional wooden rafters but for large projects steel beams are usually required and these can be quite costly.
This will often work out cheaper than using conventional steels once you factor in savings on labour access and plant hire etc.
In addition to the way your loft is constructed occasionally the height of the roof may be too low when constructed with truss rafters which means that it may need to be raised in order to accommodate a loft conversion.
The conversion from a trussed roof to a trussless roof simply involves the redistribution of the roofs weight from the trusses to beams running from gable to gable.
Use a chalk line to draw a line along the floor parallel to the lower edge of the roof from one end of the attic to the other on both sides.
The role of the horizontal beam is to tie the truss together and carry the load that would otherwise be sustained by the support and vertical timber also known as the king post.
They also take up a lot of space and the process of installation can be quite involved.
In addition the design means the trusses occupy majority of the space within the loft therefore the whole structure will need strengthening if you decide to convert your loft.
Before work can begin a structural engineer will calculate the size of the steels required.
Measure the width of your roof trusses from inside to inside.
This process involves the installation and use of steel beams.
