The most likely allowable imposed load that a typical domestic timber roof could be guaranteed to safely support is the snow load. This is generally around 0.6 kN per m2 depending on the location. Double boards under the base plates could be expected to spread the load over a few trusses depending on the centres. Assuming the scaffold is not in place in a blizzard, the max safe leg load can be worked out based on the snow load.
Of course exceeding these loads doesn't mean the roof will collapse just that an engineer couldn't stand higher loads.
Positioning legs over purlins would allow higher leg loads.
A more detailed look by a structural engineer could allow higher loads but I'd start with the snow load.:bigsmile:
