It is covered, but where the rain blows in and Sun doesn't hit it, it's green.

    That is algae, and a good power washing should take it off.

    And I would follow up with a good sealer. Hope this helps.

    Algae --- pressure wash with an algicide - available at home improvement centers

    Depending on your porch type(wood, stone, etc) and if there's any stain to be damaged, I'd suggest a dish soap and water mixture. I have a concrete porch, and typical vinyl siding, and have used this with great results. I get that gunk on my siding. Using that mix and a scrub brush takes it right off!
