Inadequate Ventilation May Be The Reason You Need A New Roof

Please take a guess at how old this roof is pictured in the photograph above. You may estimate a few decades, about 20 or 30 years, and honestly, it seems like a pretty good guess. The mold accumulation on the dilapidated roof suggests that the attic has a few years under its belt. If you guessed 30 years, unfortunately, you did not win the guessing game. In fact, gaging 10 years is still way off the mark. This roof is less than six months old.

That was my reaction too. However, in the Pacific Northwest, mold in attic spaces is not only common and fast growing, but it is also highly possible when roofing companies fail to put in extra effort to double check the ventilation of the property.

The #1 reason for attic mold is condensation.  Without proper ventilation hot humid air escapes into the attic creating  condensation on the roof sheathing that is perpetually wet and begins to rot and degrade.  In worst case scenarios, the attic condensation can be so extreme that water will drip down saturating the insulation and ceiling drywall, causing mold to grow quickly on the inside of a roof like the picture shown above.

How do you know if your ventilation is adequate and installed correctly? 

Now, before you assume that the ventilation in your home is in tip top shape, you may want to double check. The most common way to check if your ventilation is working is to check the attic with a flashlight.   The Inspector Found Mold What Now – Spring 2021First, look for discoloration on the attic sheathing which is most likely mold growth.  Next, examine the ducting to ensure it is attached and extending outward and not lying in the insulation somewhere.  Also, the roof should have vents specific to each ventilation system. One for the bathroom, the kitchen, and the laundry room. It is imperative that the ventilation systems are complete and functional.

I promise you that taking a few minutes to double check your attic will be worth the hundreds of dollars you will save getting rid of mold, or the thousands you will save by not having to replace your roof.
