A little background on how I started Roof Sparkle. A company that’s make cleaning products asked me if I could make a video for some of their cleaning products. Now I won’t go into details on who they are but they had a roof cleaner that involved the use a power washer. Big red flag in my eyes. Being a contractor for years I knew right off the bat that was a big no-no.
So the next question I asked myself what’s that black stuff on the roof. Well it’s mold. And what kills mold, bleach right. Well as true as that is bleach is only made up of 5-6% Sodium Hypocrite. And that’s great for your whites and around the house but not on your roof.
For the roof you will need something a lot more powerful. Some of you may know it as pool shock. This is made up of 12% by weight “Sodium Hypochlorite”. But because it’s as thin as water it will run right off the roof and not really have the time (five minutes) to do it’s job. So we have to thicken up a bit. Best way, add some liquid dish soap to the mix to help the SH stick to the roof for more than one second. You can go into any pool supply and ask for a gallon of shock, for about $4.00 per gallon. This is just a heavy-duty version of household bleach. And no Wal-Mart does not sell this or the big box stores.
Now of course we buy it from the manufacture and by the truckloads at a time.
When we started we used a regular bug sprayer. Use a three gallon pump sprayer, use one gallon of SH and two gallons of water (H2O) add about 4 oz. of liquid dish soap and spray from the roof top working your way down.
- clean your roof when it super hot out in the baking sun. It will kill the SH and dry before it’s clean.
- Don’t touch the SH with bare hands. Wear gloves and eye protection.
- Don’t spray your roof down first with water to cool it off.
Please do not call Roof Sparkle and ask any questions. Please ask any questions directly to me on this site please. Otherwise I’ll be forced to remove this page.. Thank you.
