Signs of Attic Mold
Initially attic mold is not harmful. As the moisture level climbs in your attic, from poor ventilation, toxic molds have an opportunity to grow. You may start to see and feel the presence of mold.
You may start to feel:
Look in the attic and you may see black mold where the roof comes down toward the attic floor. This mold will grow as the moisture level climbs eventually covering the entire attic. As the attic gets worse you may see different colored mold spots growing of green, orange, brown and yellow.
Molds give off a musty smell which can be quite pungent. As the mold grows the smell will get stronger and in many cases will not be noticed by the homeowner because they have become use to it. Pay attention when a friend visits and asks you if you smell something.
WARNING - DO NOT DISREGARD THESE IMPORTANT WARNING SIGNS!
Attics are often dark and mold loves cool and dark places. Black attic mold is especially feisty. You can tell if you have black attic mold by the pattern it makes as it spreads. It generally forms a near perfect circle or crescent moon shape.
