This is often overlooked and should
be attended to immediately. There are many reasons and variables which cause
this mold, but most important any mold is a concern.
First you need to find the problem,
for example it could be improper bathroom exhaust fan procedures, a leaky roof,
improper soffit vents and or inadequate roofing ventilation and more. Call
Gryphon Extreme Roofing right away to find and solve this problem.
Once you have identified the problem
and solutions add ventilation up to if not a little more than building codes
state to rid of all the access moisture that has become trapped in your attic.
At Gryphon Extreme Roofing we recommend adding a whirly bird / turbine to speed
up the process.
Once attic is back to dry this will
stop the spreading process due to the lack of moisture, like any living
organism. Also available for purchase are mold killing sprays, there are brands
safe for the environment. Use Clorox bleach spray bottle for the really black
spots. At Gryphon Extreme Roofing we recommend changing your roof deck,
shingles and insulation to properly rid of all these dangerous molds but also
understand this is not always affordable.
