The Difference Between Mildew And Mold

How to Remove Black Mold Stains from Attic Plywood – DIY Mold Removal Product Kit

The most common type of mold found in homes is mildew. Mildew is a surface mold that grows in warm, damp places like basements, laundry rooms, and shady porches. Mildew begins as a gray or white powdery colony and eventually turns black or brown. To test whether the wood is covered with mildew or just dirt, dab the stain with a cotton swab dipped in household chlorine bleach. If the stain lightens or disappears after two or three minutes, its mildew. If not, its probably just dirt.

Mildew can discolor and slowly harm wood surfaces. But there are much more dangerous molds that can damage the structure of your home. If a fuzzy or slimy black or green mold is visible and the drywall or wood underneath is soft or crumbles, there is irreversible rot. The damaged surfaces must be removed immediately.

This looks like light attic mold growth. If the roof is sagging/failing, I recommend contacting a roofer. The sagging can occur from leaks or excessive condensation. Youll likely need additional roof ventilation, air sealing of the ceiling and improved ventilation inside the home. The latter is important because it lowers the amount of humidity that enters the attic space in the first place. This lessens the burden on the attic ventilation.

How Mold Grows In The Attic

Mold grows in the attic due to moisture issues. One of those is improper ventilation. The attic usually has a system where the warm air from outside comes in through soffit/eave ventsand flows through the attic, rises and goes out through the ridge vents.

However, if attic insulation is covering the vents and the air cannot escape, it continues to warm up and cause moisture and condensation on the colder wood in the attic. Thus causing mold to grow. According to the US Federal Housing Authority, 1 square foot of venting is needed for 100 square feet of attic space.

Mold growth in an attic will typically not affect the indoor air quality in the rooms below. This is due to the stack effect, which moves air upward through a home. Attic mold should be approached as a structural issue. Left unattended, the moisture and fungal growth will eventually degrade the roof sheathing. Painting or sealing it will not address the problem.
