If anyone can help, I need to have a contractor paint some waterproof gunk on my edwardian zinc roof (viz water ingress into the bay window). I understand that either 'flexacryl' or 'cromapol' should do the job.
Does anyone have experience of either of these 2 products (or maybe a recommendation of another similar).
Roof got painted with bitumin a while ago but this has not sorted the problem.
thanks
