  3. Experiencing symptoms of trouble breathing. If you or a member of your family is sick with cold-like symptoms that won’t go away, it is time to check your attic.  Symptoms that last longer than normal can indicate an environmental problem like toxic mold.

What Causes Mold in the Attic?

The most common reason mold starts to form is moisture. Although, the cause of the water itself may also vary. For instance, leaks on the roof of your home may lead to mold in your attic. This may also be caused by excessive moisture in the building or home altogether.

What Causes Attic moldPin

Poor ventilation is also a possible cause of mold in attics. Having insufficient ventilation will lead to damp air in your attic, which can cause mold to form. This is particularly the case if you live in a cold climate or areas that see heavy rain. Typically, homeowners tend to heat their home in winter, which causes the hot air to rise and naturally escape through your attic. This creates condensation, which may spread to the attic floor or the ceiling, giving room for mold to spread.

Insufficient insulation can lead to a moldy attic.  Not only will attic insulation conserve energy, but it also dramatically reduces the chance of mold growth. When warm air rises in your home, good insulation should provide a barrier to control conditioned air loss in your attic. On the other hand, poor insulation will increase air leaks in your attic, which will cause condensation; this leads to attic moisture and a breeding ground for mold in your attic.

Frequently check your attic for roof leaks. Mold is commonly formed when there is moisture. Checking that you do not have a leaky roof and ceiling will enable you to determine attic mold risk. Inspecting the wooden pieces of your home for moisture and discoloration will help pinpoint water damage. If there are any, you must repair and replace the affected area so that water does not intrude your home.

Address Improper Ventilation. Without ventilation to release damp or warm air, elevated moisture levels in your attic will rise. Especially in places with generally cold climates or in the winter season, you must note that warm air will rise to the ceiling, then into the attic. The elevated moisture conditions will make an ideal environment for mold growth.

Having Sufficient Insulation. Insulation is perfect for controlling and conditioning the temperature or moisture in your attic. This ensures that the temperature in your attic matches the outside air temperature on winter or on hot days to reduce possible condensation.

Exhausts or vents should lead outside. Your bathroom and kitchen vent fans should have the air blow out of your home and not up into the attic since your ventilation system may not take care of all the moisture that may occur. Effectively further decreasing the chance of humidity for attic mold to grow in.

Attic mold may not seem like a big deal upon the first impression, but these spores will eventually spread into the rest of your attic and finally get into the main areas of your house. Toxic mold poses a significant health risk to you and your family.  Having a professional fix your attic or prevent the mold will help any homeowner achieve a healthy and clean home environment.
