Hi,
This could be my first roof clean it's a bungalow which would be good to start with it got normal clay tiles with a fair bit of moss on my plan was to scrape down the moss and gutter vac out of gutters as we go there's an old house One with the moss on and a separate building (annex) which is only a year old but tiles are going green to but no moss to scrape the next problem is there's clean, new decking around both buildings , which chemicals would you use? And would it look like new once applied?
Any advice would be appreciated.
Jamie
