SH & Shingles

Hey yall,

Quick question… I am cleaning a two story home… the home has vinyl over asphalt shingles (like a roof over the poarch) my mixture includes 2 gal 10% SH diluted with 3 gal of water.

HELP!

Sorry… my question is… will the SH solution runoff discolor the asphalt shingles?

If you’re washing siding and the housewash is running off shingles that are darkened, pretty good chance you may see clean “chemical trails”. If you’re worried about seeing the runoff effect on the shingles I would keep a good rinse going on the shingles.
