hydrogen peroxide based roof cleaners

Great White Technologies · Roof Cleaning Institute Of America Certified Roof Cleaner

Will not give instant results. Let's face it we are in a world of instant gratification and the ARMA cleaning solution is the only one that gives these results.

I've been looking into this the past couple of days and although bleach seems to always be better, surely peroxide has its place in every good contractors tool kit?

I'm told its safer for the operator, safer for the environment & its certainly cheaper!

I don't do much roof washing, but i do a lot of softwashing of painted walls & stucco, and use bleach to whiten gutters & downspouts,... would peroxide work for these applications?

Not only that, but I'm almost positive hydrogen peroxide SHOULD NOT be mixed with SH (just like a lot of other chemicals as well)

I've ordered 25kg of oxi bleach,.. at the strongest possible mix (and I'm assured that I won't need it half this strong) this will make eight 5 gallon drums costing me €10 per drum,.. compared to €22.50 for SH.

I'm not looking for instant results, and won't be marketing it that way. No one in Ireland uses SH for cleaning roofs, they just pressure wash and "Paint" a surface onto the tiles, normally charging around €3000 for the privilege. I'll be offering a gentler, safer, more eco-friendly solution for a fraction of the cost,.. something that I'm sure will more than make up for the delayed results.

sodium percarbinate is not strong enough for roof cleaning at any dilution you will have to pressure wash the roof to get it clean after applying that stuff. sodium percarbinate is for wood and laundry not roof cleaning if your still going to pressure wash to roof why even use chemical the hole reason for using chemical is so you dont have to pressure wash the roof

Both "Roof reviver" and "Roof Ox" are Sodium Perbarbinate based. Their systems are sold as a spray on and leave solution, with a 2nd application recommended on heavy soiling.

I don't mind doing a 2nd application 2 weeks later,.. To be honest I think that very few ppl in Ireland would want bleach used in that quantity on their homes, and I'm sure the local authority's would have something to say about run-off entering drains even in small quantities,.. so SH isn't really an option for me.

The Eco-friendly nonsense is big here though,.. and it sells,...

I've tried a couple of tests with this Oxi bleach since my last post.

Its brilliant for cleaning timber decking & siding without bleaching the colour from the wood, although the results do take 30 - 40 minutes to really start to appear.

Its useless at cleaning siding, eavestroughs & concrete walls/footpaths/driveways etc,.. and I mean really useless,.. it does NOTHING!

As for cleaning roofs,.. the verdict is still out. I decided to try the worst I could find first. This roof has heavy moss growth. I've administered 2 treatments 2 weeks apart,. and even after the 1st spray the moss appeared bleached/dead very quickly,... but its just not dropping off! Tomorrow will be 3 weeks since the first spray. I sprayed one section of the roof with SH for comparison,.. but the results are pretty much the same.

Is there anything which speeds up the breakdown & removal of heavy moss using only chems and no physical scraping/ pressure washing?

Pat, What is the ARMA cleaning solution you talk about? Are you talking about the apple sauce or cider that we use? Thanks

Yes, sodium hydroxide, it tries to turn everything into soap!
Back in Seattle, it was used along with the Chlorine to speed moss removal.
But I dont feel it is good to be used on a shingle roof.
Nonetheless, it does work, and works much faster the chlorine, as far as removal goes.
It dries black, and requires a high volume, low pressure rinse.

It is used with animal fat to make soap!

It "eats" stuff up through a process called saponification, as opposed to oxidation, like chlorine.

ALL Chlorin contains a little sodium hydroxide anyway, from the manufacturing process.'
It is intentionally left in the chlorine to stabalize it.

A couple gallons of 50 percent sodium hydroxide in 50 - 100 gallons roof cleaning mix sprayed on moss, or on a TILE roof, makes quick work of things.

People outside the North West,, where Moss is rampant, may react in "horror" to what I am saying ?
However, it is the pot, or the frying pan ?
Moss will RUIN a roof, quickly.'
True, sodium hydroxide is not good for any shingle roof, but it is used all the time in Seattle, where I lived for 18 years.
The alternative is letting the moss go, and watch it spread the shingles like a vise!

Some in seattle use ONLY Sodium Hydroxide, with a little surfactant.

Then pressure rinse it off after 45 minutes of dwell time.

I say use SOME sodium hydroxide with chlorine/water/surfactant, let the moss die, then go back in a week or so and rinse it off with LOWWWWWWW Pressure.

The Sodium Hydroxide will greately aid in "loosening up" the Moss, the chlorine will KILL it.
