For your particular home, your most beneficial moss control is the complete lack of shade on your main roof. You'll notice the parts of your architecture that shade portions of your roof expose the areas most susceptible to moss control. It is 10x worse once you start adding trees that tower over your surrounding area and block out the sun for large portions of the day. Sunlight, and plenty of it, is the best preventer of moss and algae on your roof, sidewalks, and driveways. Your house appears near-fully exposed so that helps a LOT. When I moved into my home in early 2000 it had zero moss problems for the first 14 or so years. That's because the stupidly planned Linden trees the city mandated lining the streets were nowhere near maturity. Once they breached the roofline the moss that had been reserved for the ground began appearing on the roof. Fast forward 10 more years and those trees are now 60+ feet tall, shade 3/4 of the home for the majority of the day (except the south side, where my neighbors ridiculous Sequoia's step up to the plate), and moss has become a significant problem. For general moss control, baking soda will also work. If you want to spray it for existing moss, dissolve a standard box (think: refrigerator box) in 2-3 gallons of water, then apply until soaked. Use a surfactant to assist in it 'sticking' to the sprayed surfaces. I use a commercial non-ionic surfactant from Liquid Harvest, and it works very well. Think of it as soap-on-steroids. For granular application of baking soda, just hit all the peaks and slant borders sufficiently. As it wets and reacts to existing or added moisture It will raise the pH enough to kill the moss that you already have, but it isn't a super-long-term solution. Baking soda (sodium bicarbonate) is fairly weak alkaline (around 8.5-9 pH on a 1-15 scale), It will weaken quickly over time as it dilutes and/or washes away. The upshot is it is generally much safer for plants and wildlife, as it doesn't contain harsh bleaches, etc. You *can* use too much of the stuff, and throw off the pH in your soil in runoff areas, so be careful.

Nice vid! Thanks! I want to see more of that lowered truck next time! 😂😂

Thank you tobby

Buy 5-10# of baking soda, where they have bulk bins, and scatter it on the roof. It is not toxic and it kills the moss just as well.

Every body watching NEVER WALK BACKWARDS ON A ROOF!

I thought you would have to wait to apply this product once the moss was already damp with rain. Are you applying this the day before it was forecasted to rain?

Do u apply only the ridges of roof? Or should i cover the whole roof? Thanks

How does it continue to be effective after a few good rains, let alone through the winter?

Nice how much was that WA house?

Usually your roof won't get moss if you don't have trees real close to the house keeping debris and shade on the house.

No tree no shade should be no moss

I'd wear one of those useless (for covid) covid masks to make sure you don't inhale the dust - seems like one would be breathing well after hauling up the roof.
