Here in West Michigan, one of the biggest issues we run into every spring is attic mold. While there may be several reasons the mold may start, the underlying issue is always moisture. The Lake Effect in Grand Rapids and surrounding areas can bring a lot of winter precipitation, and come spring, that snow and ice will melt. These conditions, paired with a lack of insulation, improper ventilation, or damage to the roof, can cause an unwanted buildup of moisture and create a breeding ground for mold to grow and spread.
When was the last time you were in your attic? The problem with mold is it rarely, if ever, reveals itself in the lower levels of the home. Under the right conditions, mold can present itself within 24 hours of moisture being introduced and can grow for months, even years without being seen in the main area of the home. If left unchecked, this mold can grow and lead to further damage to the roof decking and other structural components of the home. The longer it goes unchecked, the more it will cost for repairs and remediation.
The first step for any type of attic mold is to identify the source of the moisture, period. This means inspecting the roof for any signs of leaking, and making sure all kitchen and bath vents are working, and properly vented. Insulation and ventilation can also be leading to these problems. Check to make sure all soffit/gable vents are open and working properly. These vents can become blocked with insulation or wasp nests, impeding the air flow needed to get rid of that excess moisture.
This winter has taken its toll on many of our attics and roofs this year. Contact the pros at Great Lakes Building Concepts and have your attic inspected this spring to save money, and prevent further damage in the future.
