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
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.
2) Seal It Green seems to be available only direct from the
manufacturer. Makes strong non-toxic claims but does say to pressure
wash after applying and allowing to dry, which I'd rather not. Cannot
find any reviews. Would probably require 10 pounds, for $125 plus
perhaps $10 shipping. (It's one of these web sites that won't tell you
the shipping cost without entering all your personal details, grrr.)
