I pressure washed a shingle roof today!

[Looking Good]

Lots of moss and cedar needles everywhere. Moss was pretty thick too, took a bit to get off.
Before anyone gets too excited, the homeowner is having the roof redone but needed the moss gone first.
The first pic is just one of the views, a perk of MT living. It is overlooking Swan Lake.

What's the explanation he gave for needing to have the moss gone to re-do the roof? Did the roofing contractor request this? I suppose it would make for a cleaner and possibly safer work area for the roofer.

Maybe it is just me but my business promotes no-pressure roof washing. I would not start a thread stating that I pressure washed an asphalt shingle roof if I knew that my customers or potential customers could see the thread.

Even if they did read it, there are many, many others that might not and that puts you in the category that is not favorable if you are promoting roof washing, kind of contradictory to your business model and advertisements.

I am sure that you were helping out someone but you have to think of your business first and not promote something that goes against what you are putting out there in print, voice or internet.

I have done some jobs similar but I do not promote it as that is not the hack-image that I want for my business or what I want customers or potential customers to see.

Just my opinion.

I see your point in not trying to imply hack work. Just trying to get a few roofies excited.
Yes the roofer wanted it gone, it was like carpet in some spots, too thick to put shingles over. It was an 8/12 pitch, walking on those needles and moss would not be fun or safe.


As a side note, how would you handle a roof with moss buildup that needs to be removed for a sale/inspection or insurance?

Sodium Hypochlorite and soap!

I know that kills it and it will eventually fall off. That is my preferred method, but what if they can't wait two weeks? Say the house closure depends on the roof?
I pass on these because I do not use that kind of pressure to remove moss from the shingles.

If the house closing depends on that roof looking good, I would walk.

Not worth the hassle if the roof developed leaks from the moss or lichen being removed forcefully.

The downside could be something like this, not probable but very possible.

Homeowner: "The roof did not leak before that guy got up there with the pressure washer Your Honor but now it has some leaks that stained the ceiling, hardwood floors and now I have this nasty mold smell."

The Judge: "Son, what were you thinking getting up there with a pressure washing wand and blasting away at that roof, Don't you know that roofs can't handle pressure?" "What are you, a Moron?"

The Pressure Washing company getting sued: "Your honor, I was just trying to help that house get sold, it had moss and lichen all over the roof and make a few bucks."

It could get worse.

Just my opinion.
