The tile roof I asked about yesterday (replacing a tile) also needs cleaning. We'd like to do it ourselves rather than incurring the cost of a professional cleaner and the noise of pressure washing. We also have landscape plants and no gutters, so avoiding damage to plants is highly desirable.
I've found two products that seem to fit these specs: Wet&Forget, and Seal It Green Tile Roof Wash. Anyone have experience with either?
1) Wet&Forget is more widely distributed -- available from Home Depot (online), Amazon, and apparently from Costco (can't find it on their web site but other evidence says they carry it). Reviews on HD and Amazon are mostly very positive. Works slowly but that's fine with us. Would probably require 4 gallons for this house, lowest price I've seen is $33, so about $132.Edward
