I did use a brush. I tied a rope to it and handed down the bucket full of moss and gutter debris. It was a two story roof. easy roof but didn't want to try to carry buckets down the ladder.
yep the siding took two trips around but came off real nice. I also treated the roof. The roof had an old seagulls nest by the chimney. all in all not a bad job only took about 3hrs, and charged 1000 bucks.
no pressure here. Here is how I do it and my two options. Okay first I offer them two variations of roof cleaning. first I offer a chemical treatment. I tell them I will treat the moss and algae then leave, but the moss will be dead and stay on your roof for a while before drying up and blowing off. then I give them a second option of treating the roof then using a standard garden hose I will remove as much of the moss that will come off ( yes a standard garden hose!!!) I repeat nnnnnnnnnnoooooooooo power washing at all. the price does go up if I hose off the roof. Oh and I also retreat the roof after the hose job. so again it is ( 1. treat roof ) (2. let roof sit for about an hour) (3. hose off roof with garden hose.) (4. treat roof again.) (5. pack up and leave.) most of my costumers go for this option if they have a lot off moss.
I am new to this so this may be wrong, but don't you pull granular off with the moss by hosing it away before the roots have had a chance to disintegrate? I ask because I tried this and thats what happened to me. Maybe I didnt let it sit long enough?
Great pictures Bob!! They really show the typical conditions we deal with in the Northwest. I wouldn't bother treating the same day before the moss removal. It has no real effect that quick. I find it gentler to brush when this type of moss is dry then soft wash and treat.
My reason is, when the moss is dry it will come off with a single pass of your brush or hand. As soon as its wet with SH or water it can become like mud and creates an even bigger project for yourself.
Roof moss cleaning on composition roofs can be done gently with no significant granule loss this way.
I think you did a fine job for Northwest roof conditions! We should get together soon!

I typically spend about 2hrs using a garden hose and hosing only the big moss that will come off. I only retreat the roof after it has dried. I no this is a bugger but the home owners are satisfied with the end results and I am also. Remember the first treatment is put on thick. I saturate the moss with the chemical. I always use alcohol because I get better and faster results. The cost is typically 200 or more to do it this way because of the time and effort. Thanks for the post its been fun.
