After 83 posts a photo of you using your new ladders is now mandatory
May not work. You're meant to apply wet & forget on an overcast day.
After much deliberation and a couple of occasions during lock down where I didn’t have access to son in law for roof duty I purchased a 3.2 telescopic ladder off Amazon. Used it a couple of times now and it’s great to now have access. Ladder weighs 9kg and cost £63
Especially if it’s a dripping skylight and you are sharing the bed with a bucket ha haAgreed, good to have access with telescopic ladder when needed.
