Touching Up Light Asphalt Shingles

slickshift

I had to squirt a few wasps nests under some trim and got TAT (wasp spray) run-off onto some shingles
They are the light colored asphalt kind, and have stained kind of brown
It looks just like when thinner is spilled on them

Will a light wipe-down (top of the texture only) with some white/gray paint work to blend them back in?

Thanks in advance for any tips, tricks, or solutions

Slick i seem to remember someone asked about brown stains on shingles and i made a note oxalic acid worked to remove brown stain.

Prolly would, I always used spray paint to cover up a mistake or two, never had runoff from wasp spray stain one though.

Yeah I usually have a black spray bomb on hand for the occasional roof oops
These are light shingles though
The "bumps" are almost-if not actually-white
I'm assuming the bug spray lifted the black background gook those little white rocks are in, and stained them brown
...just a guess though

Oxalic acid huh?
I should just wipe the top of the "bumps" with it then?

slick i found the thread that was the acid answer and whoever used it said it worked its on DIY forum on roofing, thats where i saw the fix and noted it - ya know just useless info till ya need it.

By the way its not my idea its someone else's fix.

Please let us know if the acid actually works, or if you have to buy a new shingle.

Ah...I popped over and found it-thanks
It was for rust stains, but perhaps it would work for me
I'm not sure it won't remove the "white"

If I can scrounge up some junk shingles, I may test it first
If not, well...it looks pretty bad as it is, I may give it a go

Thanks

Just a thought, How about bleach? Try a sample area where it won't be so noticable, just to make sure there won't be some irreversible reaction. But i would think a bleach/water mixture of 50/50 would take away the stain and leave the shingles looking original.

...if it were a shingle, it would be replaced by now

I would've slapped one in there

...I wish it were a shingle

It's a barn type roof too so they face right out
Oooph

I tried some straight on a less visible not stained area
It left the white rocks a little darker
I didn't try try it on the stained area after that
Though, I may do that 50/50 on a stained area to test it
