white haze on shingles?

PrestigePressure · Guest

Depends on what your haze looks like, but could be a few differant things. Either salt crystals, undissolved tsp, or maybe dead lichen or moss if your roof was dirty.

What was the roof dirty with when you cleaned it? If its not dead bodies of algae/bio material, then its likely something in the sauce. I don't use tsp in my mixture, and I get a white have sometimes.

It will clear up with a good rain. If you're not a rinser, always set that standard with your customer.

I've always wondered why every shingled roof doesn't dry with a whitish haze. After all, anytime SH dries on anything it leaves a white residue behind. But even on the brown and even darker roofs, it isn't very distinctive at all when left to dry. I can see it if I look for it, but it isn't very noticeable overall.

Yes a nice god rain should take care of it.

IF you used Apple sauce, the rain will re activate the boracx and TSP, and re clean the roof, when it rains.

Its most likely a soap residue and/or the tsp. After a rain or washing, it will dissapear.
