The guttering of our house is about 5.5m above the ground. I want a ladder which will reach that height safely. I've no plans on doing any serious work up there - I just want to check it because its dripping at the moment and want to see what the problem might be. I don't want to buy one which won't reach the highest point I'll need to do (as we don't have a gable end, the guttering will be the highest point I'll be going!). I also don't really want to by buying one deliberately longer than I need (ie. I don't need an additional 1m for stepping onto the roof - I'll leave that work to pros, plus, I don't have a roof ladder!)
What is the recommended angle for ladders? If I need to reach 5.5m vertical and the ladder is at the recommended angle - what length (extended) ladder do I require? I've been looking at 7m+ ones - though I'm wondering whether
6.5m will be sufficient.The other thing is once I've got the required length I want to find a suitable supplier. Screwfix seem to do 3 section, non-domestic (ie. 150kg rather than 95kg limit) 7m ladders for about £130 with free 2 week delivery. B&Q (if you can find the required one in stock in your local store) is a similar price (£124 I think according to their website, though delivery isn't free).
Does anyone have a better/cheaper place to get it from for a similar price? £130 is the max I'll go to, so please don't suggest scaffold towers etc! Its for very occasional use and I know the risks of doing things up ladders. :)
Incidentally, any good places to purchase a standoff unit for the ladder? Screwfix does one for £29.99 but I've seen one in B&Q for £22.99 made my Abru. I'm wondering though whether the Abru one will only suit Abru ladders... Any better/cheaper place to get one?
Thanks
