My roof is covered in moss, and with the scaffolding around the house for the builders to finish the extension I thought it a good time to give the roof a good clean.
So as subject suggests, I am after a pressure washer and have no idea what to look for. I intend to use it to clean the roof tiles, and once that is done probably use it to clean the two cars - no more than once per month...
What spec.? makes? features? should I look for?
Thanks a lot in advance for any tips.
