    the basic solution if one part bleach and five parts water.
    Use pressure washer on the chimney then seal the brick, stone, stucco or whatever with a sealant.
    NOTE: Do not use pressure washer on the roofing material unless on low pressure like the hose.
    you can still use the upper solution for the roofing but roofing supply houses have a roof cleaning solvent that they sell which is called ShingleClean. Read the instructions prior to buying and using.

    Clorox and a pressure washer! You can rent a pressure washer at any local building material store, such as Home Depot. Be ABSOULTLY sure you start at the top and spray down the roof. Be sure and hold the tip of the pressure wand away from the shingle3 feet or so until you can lower it slowly to the point wherre it will clean without blowing your roof off the house. Take your time and don’t rush it. It took years for this stuff to grow up there, so don’t think you are going to get it off in 30 minutes! As for the Brick chimney, there is a special cleaner just for brick and I would suggest you use this product to secure the intergerty of the color of the brick. Take your time, be smart, move slowly, and GIT-UR-DONE!!
