Most covered porches will have moisture problems which breed mold and mildew due to the fact moisture gets on the ceilings and can not dry out fast enough, especially during the rainy seasons.

One suggestion would be, if your homeowner has a ceiling fan on this covered porch, keep it running during the rainy season. If he does not have one, tell him to add one. This will help but still may not solve this problem.

Also make sure to avoid using oil base paints on any ceilings, siding or facial boards, only use enamel latex semi-gloss or flat paint for the best results to help prevent mold and mildew, also use a mold and mildew inhibitor added to the paint. Using mold and mildew inhibitors will help, however, it will not last forever. After a few years mold and mildew will return. Nothing really stops "outside" mold and mildew from coming back and attacking our siding, facial boards, and most of all covered porches.

Care and Maintenance is to wash the ceiling and all infected areas once a year with a 1/3 bleach 2/3 water mix using a pump-up-sprayer. Wear eye protectors and keep the infected areas moist with this mixture for at least 15 minutes.
