Dangers Lurking In Your Attic

Do you have mold in your attic? Can you smell an odor in the attic? Is your wood framing, roof and insulation wet? These are commonly what we find when we are called out to a home or business for attic mold inspections. But don't worry, Alliance Restoration is here to help. Below are some typical problem areas that we uncover during the inspection process.

Improper Bath Fan to Soffit Venting

Soffit vents are generally intended to allow fresh air to ventilate up into the attic, not exhaust air out. The best way to vent a bath fan out of the attic is through a dedicated vent in the roof itself. However, sometimes bath fans are vented through a soffit. This is fine as long as the vent duct is properly attached to the soffit. In some cases, vent ducts are simply routed to the area of the soffit, but not attached to it or sealed properly. When not properly attached, moist air exiting the bath fan duct gets caught up in the air entering the attic space from the soffit causing attic mold.

Bath Fans Venting into Attic

A Bath Fan Vented Directly Into the Attic is an Almost Guaranteed Attic Mold Problem.  Bathrooms with tubs or showers can generate a great deal of moisture, and bath fans are installed to remove this moisture from the bathroom space. This is a great system as long as the fan does not simply relocate the moisture to another area within the confines of the home. Moisture trapped inside the home, including within the attic, has a high potential for becoming a mold problem.  A big part of maintaining good indoor air quality is making sure all bath and kitchen vents are properly ducked to the outdoors.

Blocked Soffit Vents

Attic Ventilation: Fresh Air In, Moist Air Out. Generally speaking, attic ventilation relies on the fact that heat rises. Cooler, fresh air enters into the lower attic through soffit vents.  Warmer attic air exits out through a higher ridge vent and/or multiple roof vents. This air exchange is what helps keep moisture purged from the attic space. If your soffit vents are blocked, this prevents or reduces the amount of incoming air. The less incoming fresh air you have, the less chance you have for ridding unwanted moisture from the attic space thus increasing the risk of developing attic mold.

Humidifier Set Too High

Is Your HVAC System Over Humidifying Your Indoor Air? It is best if you can maintain the relative humidity level within your home to between 40% and 60%. As far as mold growth is concerned, we like to see indoor humidity levels kept below 60%. During winter months our air can get very dry, and some HVAC units are equipped with humidifiers to add moisture to the air. If these humidification units are set to high or malfunction, the indoor humidity levels can exceed 60% and contribute to mold growth including in the attic space. We feel it is a good practice to keep an indoor humidity meter handy to make sure your home stays below 60% relative humidity at all times.

Inadequate Ventilation

Does Your Attic Have Enough Ventilation? Similar to how heat rises, homes are designed to naturally vent out the roof. Naturally occurring moisture within the home from cooking, bathing, dish washing etc can end up in the attic space. This can be fine, as long as the is an adequate air flow exiting the attic to carry the moisture out with it. If your attic does not have adequate ventilation, or if there is too much moisture being produced in your home, attic mold will likely be an issue at some point.
