It depends on how extensive the mold is, and sometimes on what you are willing to pay for. Often the mold is just in a few areas, requiring limited structural replacement, or just cleaning. Obviously, any roof leaks --­ shingles, flashing, etc. -- must be fixed to prevent future mold growth. Also, attics rarely visited don't need to be as clean as living spaces.

It is not uncommon to find mold on the underside of roof sheathing. Usually this is the result of insufficient venting, such as venting bathroom or laundry exhaust into the attic and/or insufficient peak or soffit vents. Moisture-laden warm air that enters the attic rises, contacts the cold sheathing and condenses. If this happens often enough it can affect the structural integrity of the roof through warping or rot.

Black mold has the potential to cause health problems. Black Mold spores produce allergens (substances that can cause allergic reactions), irritants, and in some cases, potentially toxic substances (mycotoxins). Inhaling or touching mold spores may cause allergic reactions in sensitive individuals. Allergic responses include hay fever-type symptoms, such as sneezing, runny nose, red eyes, and skin rash (dermatitis). Allergic reactions to mildews are common. They can be immediate or delayed.

Unsightly black stains on shingles are often mistaken for fungus, mildew, dirt or oil, but are actually caused by a hardy type of algae. This common problem has increased during the past 20 years, indiscriminately settling on rooftops from coast to coast. Dark algae streaks are visible when algae cover the normally vibrant colors of white, cobalt blue or hunter green roofing granules. See similar questions...

Due to the general movement of air up and out of the home, mold in the attic is not likely to affect the interior of the home. Mold growth in the attic is generally caused by condensation on the roof decking unless an apparent leak is present. The conditions that lead to the mold growth should be corrected and the mold treated to prevent future growth. See similar questions...
