How would you clean this roof?

I gave an estimate on this roof today, but the owner wants me to be sure that I can do it before I get started. He had another roof cleaner walk away after starting. I'm honestly not sure how I would do it though. It looks like it's too steep to walk, and I don't think I can reach the top with a zero degree nozzle. At least not with the 4 GPM pump that I've been using. Any tips on how I can safely wash this, and how much Snot I'm going to need to stop runoff?

Josh, I am not seeing why you couldn't reach the top w a zero tip. You could put on an extension wand if needed. I wouldn't use any more Snot than normal, just adjust your spray technique to control the run off. Looks to me you could also walk up on both of those front gables and stand on the ridge if needed. Also looks like you got full gutters so that should help as well.

What Doug said.

Here is one of the tougher ones we did last year.

I don't see to much of a problem walk up the valleys to get to dormers you should be able to spray most of the roof from the front peaks.

Okay, maybe a zero degree tip will work, I just wasn't sure. This is my first roof cleaning job where the roof looks like it might not be walkable. I guess I was just a little nervous especially since the home owner wants me to be positive that I can finish the job. Otherwise, I probably would have just gone for it and figured it out along the way.

Josh if you have never walked a steep roof make sure you walk in the valley for better footing and bring a helper just in case. Its very easy to loose your footing and go down if your not comfortable use a longer ladder and lay it up the the roof and spray from that.

Josh, dont worry You can make that one happen. Just be careful. when it comes to roofs i usually dont push the limits, theres no need to. with the right mixture ( you will have to find that mixture ) that roof should clean like up easily from a distance.

If you have trouble cleaning that roof you are in trouble. That is a simple roof.

A bit harsh, but true..... There should be no problem to clean that roof with a 4-5gpm 60psi 12v pump, a 0050 tip and a 4040 or similar fan tip.... From a ladder with a stabilizer bar, standing at the gutter line.

I was thinking the same thing Andy.

Use a 0020 tip. This orifice will be a little small for that size pump. And yes it will cause the pump to cycle a bit more but you'll get the distance you need to complete the job. And yes that roof is simple.

Thanks for the help guys. It may end up being easy like you guys have said. I have only been doing roof cleaning for less than a year though, and most of the ones I have done were much smaller, and easily walkable. This one just looks a little intimidating compared to those I guess. I'm sure it will be fine.
