What Causes Mold in an Attic?
The Link Between Ice Damming, Condensation, and Mold
Spring is finally here and temperatures are beginning to warm up. Because of the long, cold, and snowy winter, one of the key concerns we are encountering is ice damming.
One of the major problems caused by ice damming is condensation in the attic. Condensation is the result of the mixture of hot and cold air, which causes water in the air to cool and collect. In most cases, this will show up as frost in the attic.
The major concern with moisture in the attic is that it can lead to mold which could impact your health and the structural integrity of the home.
According to Calgary based Epic Roofing and Exteriors, there are four key causes of condensation:
1. Lack of air flow in the attic.
2. Insufficient insulation around ducts; this is the common reason you will notice water entering through a bathroom or exhaust fan.
3. Water or snow entering through gooseneck flashing on the roof.
4. Snow covered vents do not allow the attic to exhaust effectively.
You may have condensations issues if you notice these following signs:
1. Staining on your ceiling.
2. Condensation on your interior walls/ceiling.
3. Water entering in through a bathroom fan or kitchen/microwave hood.
If you have noticed any of these condensation signs, then the best course of action is to locate the leak and determine the cause, which may require the assistance of a professional.
How Do I Know If I Have Mold?
Once the cause is identified, then the next step is to determine if you have a mold problem. Mold is nature’s recycler and will only grow and proliferate when moisture is present. Condensation in an attic, heat and humidity from household activities (cooking, showering, etc.), and the fact that the attic provides an excellent food source for mold, provides the ideal conditions. All mold needs to grow is 24 to 48 hours and as long as the proper conditions exist, it will continue to proliferate.
The best method to determine if you have mold is to contact a professional for a mold inspection and air quality test. During the inspection, tape or swab samples of suspected mold may also be taken and sent to a micro-biology lab. Once the type of mold and spore count is determined, the Professional Remediator will provide you with a scope of work on the best way to remediate the mold.
Dry Ice Blasting: The Best Attic Mold Remediation Solution
With respect to attic mold, one of the best methods to deal with it is with Dry Ice Blasting.
The key ingredient required to dry ice blast is dry ice pellets which are created by taking liquid carbon dioxide from a pressurized storage tank and expanding it at ambient pressure to produce snow which is compressed to make hard pellets.
Dry Ice Blasting is a process in which a blasting gun fires dry ice particles, about the size of rice, at extremely high speeds to impact and clean the surface. The particles are accelerated by compressed air. When the dry ice hits the surface, it goes from a solid state to a gas state without passing through a liquid phase and cleans the surface.
Dry ice blast cleaning is a favored method of cleaning mold from an attic because it is so effective and efficient. The video below demonstrates this.
