We have recently encountered some homes in New Hampshire that had attic mold that needed to be removed. The three main causes of attic mold are as follows:
1. Lack of adequate insulation. R38 insulation is recommended.
2. Improper ventilation. And finally…
3. Bathroom vents are being vented into the attic.
In a recent job in Claremont, NH, the homeowner had hired an insulation company to insulate their attic a few weeks ago. The "experienced contractor" decided that because there were no soffit vents, that they would fill the soffit areas with blown insulation. This of course created a major ventilation and moisture problem which caused mold to grow in the attic! Remember, it only takes about 24-48 hours for mold to form.
Here's how we solved the problem. First, we removed the insulation from the soffit areas and then vented that area. We cut in a ridge vent and then we removed the mold using dry ice blasting. Once the proper ventilation was installed, we re-installed the insulation.
If you are noticing ice damming on your roof, you may have an insulation problem that could lead to mold. Please call us to have the job done correctly, the first time!
