Roof moss and algae control powders

[DriveHard]

Have used this in a 50/50 solution of Clorox/Water and 1 oz HTH

this is what I used...worked great

Yeah there is a reason everyone down there over 60 looks like a road kill lizard.

Yes, but you won't have to continue to wear this outfit when you play pickleball eight out of 12 months per year.

Newer asphalt shingles contain copper granules mixed in with the rest of the granules. It prevents moss and mildew for 10 or 15 years.

Lots of lore about Tide powdered detergent. It kinda works.

I know what works: copper sulfate. But can leave stains on lighter colored roofs and copper in the runoff? Can kill vegetation

Zinc sulfate should work. Ordered a couple pounds.

I think Tide is a base. Which as I understand would actually help algae.

I like bleach for killing stuff. The ratio is up to you, I normally go no more than 10%

Yeah some we can't cut - neighbors fenceline trees on shop side - house has no trees overhanging but when wind blows unpreventable from the forest the amount of small debris. For sure though, cedar trees and other evergreens are worse than any deciduous tree around here.

Especially on the north side of your house.

 

[Lubener]

Doesn’t work. At all.

Then you did not use it properly.

You assume much. I used the Costco kind multiple times over the years at my old house. It did NOTHING. I followed the instructions to the T.

Especially on the north side of your house.

No trees around the house thank goodness, just the west side of the shop.

Most (not all) algae prefer slightly acidic conditions, soaps do tend to be on the basic side, and I doubt Tide, a soap/detergent would help it grow with other goodies in it.

I like bleach as well but don't want it going straight in the under ground seep pit.

Most have zinc, sometimes copper, some have both.

The problem areas are the downspouts from the second story roof meeting the lower roof. Basically the downspouts pour right on the roof by design and the junk builds up there and near there.

I like it when builders extend the downspout all the way to the first storey gutter. Could you do the same?

Copper sulfate kills tree roots. That's what's recommended if you have a pipe blockage.

I use wet and forget each spring...on the siding and on the roof....both continue to look great...I use the one that you attach to your hose...spray it on and forget about it....

It would look goofy on the front of the house. Will post pictures later.

My detergent mix is working- need more rain. I need some to the right there up by the wall.

I'd lay a copper or zinc strip in that gutter.

I can scramble rocks and hike in the mountains all day @ 66 YO. But the roof pitch just won't let me throw my leg up there. EVERYTHING, every part of my body, including my 'nads, just says NOPE. So I sheepishly climb off the ladder.

That said, it wouldn't help with the dank NW green growth to the right

You have shot down every suggestion. Call a roofer.

No, some good ideas back and forth. No one here seems to use dry, which works the best on heavy build up, which was the point of my OP. Wasn’t really asking for suggestions - but shot down? No, I hadn’t shot down Spray and Forget. I'm going to try it - especially on the green area to the right in the picture above.

My zinc sulfate came, so I'm going to mix a batch 50/50 with sodium borate.

I had a roofer treat it once. Blow off with a 20V battery blower and treat with a little zinc sulfate solution, $500. I can afford that, but kind of a rip off.

Copper sulfate (powdered by me), cheap powdered detergent and Borax mix - pics from 2 days ago. Will take more pictures today, but is working

Good choice to stay off the ladder. Your wife is counting on you being around and productive for awhile.

Nothing I can think of more dangerous to a 55+ man than a ladder. I always think of General Shelton special forces guy with nearly 1,000 jumps from aircraft, both static line and haho/halo, and what happened to him on a ladder shortly after his retirement from the military.

Safe ladder ok. Pitched roof unt-uh but applying this stuff not scary

Wet and Forget is all you need....
