Has anyone ever seen a roof that looks to be like a coblestone drive-way? How would you go about cleaning something like this, Its not walkable by any means but you may could repel off the top.
This is a prime example of a roof that with a house wash mix and a Pitch witch rinse can make an instant difference....Personally I don't see the "softwash" rinse working on aged slate like this.
Hahaha! Let me, Nick, Kory, or Chris at it. Tile, Shingle, Slate etc... It doesn't matter. A non Pressure application WILL work on it. Boost up the % and the surfactant and spray. A couple of good rains to rinse and she'll look like new. :yeah:
Prior to meeting with Larry and seeing the softwash method of cleaning roofs first hand, I too was looking at rinsing with a pitch witch, water broom, etc...
I have seen the low pressure / softwash method first hand. Not only does it work very well, but it can be done at a fraction of the time & cost of manually rinsing using any method I have seen.
If your done with this, or other online pressure washing / roof cleaning forum's, because of this thread, it's only to your detriment.
