They could clean the window from on top with a reach and wash taken up through the house. They could probably get there without actually stepping onto the roof. I was thinking that, yes. But is that OK for the english regulators?

October 17, 20215 yr Author 2 hours ago, joe90 said: I have only just come across this thread and as an ex mountaineer and climber find the rules over the top. If it were my roof I would simply install a large eye bolt near the side of the large window, secured down to the roof trusses, reachable from the access small window, lanyard (short enough to not fall over the edge of the roof) and screw carabiner and harness. This will be sufficient to clean said window but not fall, so no arrest equipment would not be needed. I still have harnesses and ropes many years old and still in good condition (they have to be stored correctly, no damp or sunlight. It’s simple enough to inspect ropes fir chaffing and harnessing fir stitching problems) but then again I would clean my own windows ?. Just out of curiosity, of course a rope and hook shouldn't *just* be able to hold say 150kg (assuming our average builder isn't that obese) but also the strain of such a 150kg load falling straight down for say 1m first - short drop and then a sudden stop, as a matter of speaking How do you spec this out? What is the actual requirement on such loops and ropes? Do you have any tips (URL?) for what type of harness and rope would be needed? Edited October 17, 20215 yr by puntloos
October 17, 20215 yr An anchor point for fall arrest (single person attachment) requires a 15KN pull test .. approx 1.5 tons. This is to simulate a 100kg load falling 2 metres. in reality you should use a short landyard to prevent going over the edge so work restraint.

No, I said “short enough to stop falling from the roof” I.e. to stop the wearer going over the edge, not a “fall arrest “ first hit on tinternet shows a fall arrest https://www.screwfix.com/p/delta-plus-elara130-fall-restraint-kit-1-5m/6674R?tc=IA6&ds_kid=92700048793290415&ds_rl=1244069&gclid=EAIaIQobChMIx9P9ua3S8wIVk2DmCh36dwUnEAQYASABEgKdFPD_BwE&gclsrc=aw.ds, it’s not a “hook and rope”, it’s a locking carabiner and landyard with full body harness designed specifically for this purpose. What more is required? Edited October 17, 20215 yr by joe90

Therefore needs access equipment on the ground too. Trust me I have spent a long time hanging in a climbing harness (not a full body harness) and it does not cut off arterial blood ?. Plus I am talking about a restraint (too short to allow the wearer to venture over the roof edge) not a fall arrest!.

Top 2/3rd had nowhere to put in protection. Pretty scary that was. Did see a sunfish from the top, so worth it.

I do believe health and safety is OTT, people should be allowed to make their own judgement and take responsibility for their actions without the constant blame culture. Like a previous poster, I was pulled up by a BC inspector fir climbing a ladder that had not been tied off, when I asked him how I was supposed to tie it off from the ground he muttered and walked away. Jobs worth with no real grasp on reality.
October 18, 20215 yr Health and safety isn’t over the top it’s there to protect you, your kids, grandkids workmates at work etc. too many people take short cuts when building.
October 18, 20215 yr @puntloos do you intend cleaning your own roof lights?, if not find someone who will and ask them what they consider adequate (and get it in writing!)

A lot of H&S is definitely over the top! recent job, working on a scaffold with a platform height of 18inches the guys had to wear full body harnesses and remain clipped on at all times, but in the office they can stand on a chair to pin posters up. yes the chair is higher than the scaffold tower fitted with handrails and toe boards etc. Edited October 18, 20215 yr by markc

A decent idea. No I don't really intend to clean them myself if it requires any sort of skill to not die. :)
October 19, 20214 yr To help the window cleaner to survive, a strategy would be good. I think I would favour access through an opening skylight. Next choice is one ladder onto the lower flat roof (with a tie position permanently fixed at the eaves) then an additional ladder from there to the main roof (tied at the top, and a good idea to have a fixed block at the bottom too. That way each ladder is relatively short.
October 19, 20214 yr We have large inaccessible velux in our atrium, have never washed them in 6 years, rain seems to do the trick. I assume even your flat windows would have some profile to allow rain to run off? Have you considered a self cleaning coating on the outside to minimise any need for actual cleaning?

As I understand it we need to aim for 2.5-5% incline, and yes, was planning to have that coating too. I'll see if I can get away with an openable skylight for access but perhaps it's overkill
