Actually I'm still not as confident as I'd like to be before I start this and I definitely don't want to have to leave the job unfinished. Basically it's what they call a "saltbox" roof I heard. The distance between the gutters and the peak of the roof is fairly large due to the fact that instead of going back down after it reaches the mid-point of the house, the roof keeps going up until about 3/4 back. I hope I'm describing this right. It is a little too steep for my comfort level on both sides. On the back side it's not a problem cause the gutters and peak are fairly close and I can easily rinse from the ladder. The front is where the problem lies. So, after i spray with chem. (either with my x-jet or duraflo pump) how can i rinse the roof without pressure to get the dead green mold or algae off. I was thinking of a garden hose just arching the stream to hit the algae off from the top but I would assume it's better to get as close as possible so I can clearly see the algae. I dont want it growing back in 3 months if I missed a spot. Another thought was to try to get the ladder to about the midpoint up the roof by taking a 40' and backing it away from the house to try and angle it over the gutter and up on to the roof itself a good ways up. Anyone know if this is possible. The roof is angled back quite a bit so I dont know if I can hit it with the ladder without the gutters gettin in the way. Anyone who is familiar with this type of roof that could help I would appreciate it very much. Im not really interested in any of the on roof pressure attachments.
