palnews26 Report post Posted February 25, 2018 Anyone ever clean a stone roof? I haven't checked it out but the customer says its stone not slate. I imagine the standard roof mix would work just fine. Any thoughts? Thanks in advance. Share this post Link to post Share on other sites
palnews26 Report post Posted March 1, 2018 Checked out the roof today and it's not stone. More like these above. Possibly reclaimed French Flat roof tiles. Looks like these things will soak up the mix like a sponge. Maybe you FL guys have seen these but here in the north east not so much. I'm still thinking standard mix but I think I'll do a test area first. Any tips for this. Share this post Link to post Share on other sites

Shingle Brite Report post Posted March 11, 2018 It will cleanup just like every other roof cleans up. You will probably need at least 40% and maybe 50% ratio to get it clean and might have to hit some of it more than once but it will work. I would tell the owner the algae stains will be gone when you leave but the lichen will still be there but not very noticeable and dead as a hammer. It will decay and weather off in a few weeks. Also, don’t be surprised if those tiles “bleed” color when you clean them. It won’t hurt anything but might scare you if it happens. 1 Roof Cleaning Virginia reacted to this Share this post Link to post Share on other sites
