First roof cleaning job - Small porch roof, what's is the best chemical

[steele]

I've just picked up my first roof job, just a small porch rood job. Perfect to get paid practice on.

I was initially thinking of removing all moss by hand, giving it a good brush then use blackwash to treat it.

I was looking at blackwash for it's ease of use, no mixing etc. I'm using a backpack sprayer (Once Gardiner provide me with a working one! )

What would you use on this job, bearing in mind I do want to use a hypo as I plan on doing more of this work and need the experience.

Many thanks

Answered my own question, I'm going to buy the Hypo and mix it myself. Happier with the cost and the amount it will produce.
