In New Orleans after Hurricane Katrina, many homes were condemned not because of damage caused by wind but by rising and receding water that left deadly black mold in its wake. Mold is caused by a combination of moisture, warmth and stillness; something we’re experiencing a lot of here in the Triangle Area of North Carolina. When water leaks from the roof into the attic and sits, microscopic organisms in the water begin to feed off of any organic material they can find. Eventually they grow into overpowering colonies of black mold that affect your health as well as your living space.
In North Carolina, mold is a major concern to be taken seriously. Mold can even develop on your roof, attaching itself to the granules of asphalt shingles. This certainly detracts from the appearance of your home, and it threatens the health of your roof.
Additionaly, we create a lot of moisture in our homes—laundry, dishwashing, house plants, bathing, fireplaces and other appliances add microscopic water droplets that need to escape out of the house and back into the atmosphere. Unfortunately, in attempting to build more energy efficient houses over the past 30 years, the building industry has been constructing homes that are that are “tighter” than ever before. As a result, they have inadvertently “captured” all that moisture in your home. All of that moisture gravitates upward into the attic and if not vented out, it will condense on cool surfaces. If the back side of the metal roof is exposed in the attic, it creates an ideal situation for severe condensation. However, condensation can also occur on the back side of solid decking if moisture is not properly vented out. All this condensation can become a potential haven for mold.
Good ventilation can prevent mold in your North Carolina home. A Classic Metal Roofing System will help ventilate your roof and attic. To learn more about protecting your home with a quality metal roof, contact McCarthy Metal Roofing Systems.
