BELOW ARE 2 CUT and PASTES FROM THE ASPHALT ROOFING MANUFACTURERS ASSOCIATION.
I THINK USING A BROOM WOULD REMOVE GRANULES and HOT WATER WOULD MAKE THEM COME OFF EASIER THAN COLD WATER WOULD. BUT THAT'S JUST MY THOUGHTS???
WHAT THE ARMA SAYS SHOULD BE RELIABLE, AS THE ROOFING MANUFACTURERS DON'T WANT PREMATURE ROOF REPLACEMENTS UNDER WARRANTY.


<P>"A typical solution should be one part chlorine bleach and one part water. Other cleaning chemicals or methods should not be used without approval of the shingle manufacturer.

First, gently disperse this solution on the roofing surface. Use normal precautions for handling bleach including eye protection and rubber gloves. Be sure to apply it carefully to avoid damage to other parts of the building and the surrounding landscape. Avoid scrubbing the surface, as this friction may loosen and remove granules
Caution!

High pressure washing systems are likely to damage asphalt roofing and should not be used on asphalt roofing for removing algae or for any other purpose."

I have some of their websites listed on a page in my website, where you can click their live links and read what methods and chemicals they specify.
It's here:

You can also watch me do it below, on Youtube. I use a 5 gpm 60 psi 12 volt pump. After the manufacturer specified chemicals travel through 230' of 1/2" ID hose and out a 1/4" gun, it's about 40 psi. Even that is just for delivery of the mix,the 40 psi plays no part in cleaning-it's a "No Pressure" cleaning system:

All of the plants were pre-wet like you mentioned. The home had gutters all the way around that we cleaned/flooded and re-routed prior to cleaning.

No hot water is necassary. No scrubbing especially on asphalt shingle roofs. A 12.5% of proper ratio to water mix will do the trick.

In most of the houses we can see that the roof tiles completely covered up with algae. Although these The black mold-like stains doesn't cause any damage, it does look bad. The less expensive solution is to spray wash the roof with a 50 percent mix of water and bleach to get rid of the algae. Just be sure to wet your foundation plantings first, and rinse everything in clean water when you're done. As plants don't like bleach, wetting them with plain water first protects them.

To keep the algae from coming back, insert 6-inch-wide strips of zinc or copper under the row of shingling closest to the roof peak, leaving an inch or two of the lower edge exposed to the weather. That way whenever it rains, some of the metal molecules will wash down the roof and kill any algae trying to regain a foothold on your shingles. This is the information that I got from an article https://www.bobvila.com/articles/bla...eck-for-algae/

But I would say that the best method to prevent the algael attack is to install good quality black roof shingles. It is because the chances of being attacked by algae is less in black roof shingles compared to other shingles.

Do not use bleach, there are more efficient ways to clean roofs. Vacuum cleaner are good though, but you should be well prepared.

What about a painted standing seam metal roof? Besides "checking with the manufacturer" for a cleaning solution mix, is there a general algecide that is safe to use on this roof material?

Darn, I could believe there are tips like these. In my personal experience, I'm having a hard time cleaning those roofs. It's not a one-man job for real.

Instead of going through all this trouble, the wise thing would be to call in professionals to gutter cleaning melbourne
They have the expertise and specialised equipment to clean gutters and downspouts quickly and efficiently of even the most stubborn sludge and waste. Their trucks are fitted with stable hydraulic ladders, the cleaning is done with powerful vacuum cleaners and the dry leaves and sludge is transferred to containers on the trucks and taken away. It is that simple!
