Killing moss and algae on patio or roof

Rock salt disolved in warm water, chucked over the area, leave to dry, sweep off.No good for roofs unless you are 40' tall
Jeyes fluid, use as instructions on bottle.
have used the bleach method, which works too

 

Dont have your problem nixonf23, just paint preservative every 5 years, except on the Oast House Spire that is..
