We cleaned our first glazed tile roof and with great results as you can see in the photos. We used a 50/50 mix with Gain in addition to Ammonyx LO.Even with the extra surfactant, the solution would quickly run off the tiles. These glazed tiles are smooth like ceramic tiles found in a kitchen. So we applied three light coats of solution versus one heavy coat that would have just ran into the gutters. This gave the solution plenty of time to set. I think we could have stopped at two coats and I'll try that on the next glazed tile roof. We then rinsed in which the algae, lichen and moss came off quite easily.
Looks great Dave and a timely post for me. We have a large and steep ceramic tile roof to do next week. The house is going on the market and they want the moss off ASAP.

EXACTLY, great point. I wouldnt have used a 50/50 mix, however the point about doing light coats and allowing to set was dead on. Congrats, you don't get allot of tile roofs up your way.
Watch going too hot on your mix with glazed or slurry coated tiles. The hotter mix can etch or remove the glaze.

I would try NP-9 to make it stick. We did a large church with a 14/12 pitch and found the NP-9 to be extremely helpful. The word is, it is not compatible with SH.

Brett,
In your experience with NP-9 did it seem to impede the effectiveness of SH or not really noticeable?

I didn't notice any difference in the actual working of the solution. I always hear is is not chlorine stable but I never tried to use the mix the next day to see what it does. On the church, we emptied the tank on the steep roof and stated fresh the next day, moving to lower pitches using other surfactants.

I do hear of incompatible chemicals that don't really degrade the solution unless you let it sit overnight.
