We have a large warehouse with a central valley gutter which needs to be cleaned out to remove build up of debris. The gutter is load bearing but the roof structure is fragile. Access up on to the roof is via the main office plant room and is fairly inoccuous but in the area of the warehouse roof there is currently no lifeline or anchor points for attachment, no barrier along the length of the gutter and no edge protection at the far gable end. Suggestions gratefully received.....

Liz,
if, as you say, you have existing safe access to the roof and you have personnel who are trained, you could use a valley walker device. The one that we looked at was supplied by a company called "easi-dec".
Might be the answer to your problem.

There are a few companies out there now that have converted equipment into miniature 'gully-gulpers,' the pipe is big enough to move a house brick from up to eighty metres. Access initially is by whichever MEWP is best for task, up one side with the pipe and the lorry mounted motor takes over by pushing the pipe on it's journey sucking as it goes. If it will reach all the way in one-hit all the better, on the return route the small attached high pressure pipe washes the gully out, and job done.

If they are of a syphonic nature the only stumbling block for this equipment is guiding it to the down-pipe area, it can be a huge fiddle but does get there in the end. What I like about this method is absolutely zero roof access for personnel.

It won't fit every occasion but it is my preferred method for safely cleaning this type of gully. The trade name for the one I use here is 'big-brute,' I imagine it could probably be called something else by other manufacturers.
