Common Mold Causes
- Inadequate Ventilation to an Attic area results in elevated levels of water vapor from the livingspace causing condensation and mold on the bottom of the roof plywood and framing.
- Poorly designed roof systems that are unventilated or inadequately ventilated, resulting in condensation and mold on the roof sheathing. Many times water stains and/or damage to the ceiling finish are observed and at times mistaken as a roof leak.
- Underfloor crawlspaces that have no moisture barrier present over the earth floor to reduce soil moisture evaporation. If left unchecked, evaporating moisture can significantly elevated levels of water vapor throughout a home causing mold.
- Small livingspace areas that are not regularly ventilated with open windows. As a result of occupants using the home, they generate water vapor that gets trapped inside. Elevated water vapor leads to condensation, typically in areas that are cold or have little air flow. Condensation is a common cause of mold.
- Pipe bursts that go for a period of over 48 hours. Hot water discharges tend to propagate mold quicker than cold water losses.
- Slow leaks will take longer and often go unnoticed. Any evidence of moisture should be addressed immediately before mold and grow.
- Houses that are left vacant and unheated for an extended period of time can allow water vapor to create dew when temperatures are reduced in the home. Regular checks of vacant homes are essential in preventing costly mold damage.
- Roof leaks and Ice Dams are common in the Tahoe area because of the large amounts of snow and sunshine we get. Having a well maintained roof is the first line of defense, though when issues happen, the resulting water needs to be dealt with.
