Loft Boarding and Loft Ladders

[Simon42]

I thought the general consensus was to AVOID loading roof trusses?

Trusses shouldn't have much extra load on them. However if they are supported mid span from below properly by block walls not stud on stud (unless designed for it) or the re-reinforcement timber for the new loft floor spans near enough/to the walls the trusses rest on then that's a different matter.

There are so many variables that there's no simple answer without specifics of overall construction.

My understanding from the surveyor was that the frame was the full size of the existing one.
With the downward force onto the trusses I thought that meant that the joists wouldn't be impacted and therefore no risk of issues with the ceiling.

There is a light storage loading included in a Trussed Rafter design of 250N/m2 on the bottom chord of the trusses only. You just need to remember the decking system eats into that provision so if your system has a weight of 150N/m2 you have used over half the load in boarding out.
