Should you Paint Over Black Attic Mold? NO

Nother reason that you should never paint over black attic mold, is that the paint acts like a moisture barrier. Blocking the natural moisture from entering the attic through the sheathing causes the plywood to absorb all of the water. This can cause the sheathing to de-laminate which will shorten the life of the roof. which is just a clear lacquer that is sometimes used, because it also acts to seal in the moisture. Wood needs to breathe, temperatures in an attic can vary from 170 degrees Fahrenheit to below zero.

White paint can also cover up a poorly remediated attic. The mold removal may have not removed the mold and just painted over it. With the paint covering everything it is impossible to do a proper inspection of their work. So while it may look great when they leave in a few years you can have the mess above

 The reasons why mold may begin to grow in an attic;

  • Too much humidity in Attic from the HVAC system humidifier

  • Insufficient soffit venting (from the eaves)

  • No attic Ridge venting (at the roof peak)

  • Inadequate Attic gable venting (side vents)

  • Not enough or improperly installed insulation (poor thermal envelop)

  • Clothes dryer venting into the attic (source for high humidity)

  • No bathroom vents, so humidity builds in attic (source for high humidity)

  • Bathroom vents improperly venting into attic (source for high humidity)

Attic Mold And Ventilation:
A common occurrence in a surprisingly high number of attics, particularly in the New Jersey climates, is the growth of mold. A common cause of the problem is inadequate ventilation into the attic and with warm moist air rising through the ceiling and into the roof it can get trapped providing the perfect conditions for mold growth. For this reason alone, mold removal should be undertaken as soon as possible.

Attic mold can spread completely through the entire attic. Many molds, such as  black mold, present a health risk, mold removal would be best left up to mold remediation experts.

Ventilation is the Key to Mold Prevention:
Incoming air to Attic : The most effective way for air to enter the roof is through vents that are placed in the soffits along the eaves. Continuous strip vents provide the most reliable ports as well as rectangular vents
(if enough are installed).

Outgoing Attic air : Stale or heated air escapes through the top of the roof. There are many ways to achieve sufficient attic ventilation including : Ridge Vents, Turbines or Powered Vents, Box Vents and Gable End Vents.

Our Mold Removal Procedures

  1. Mold must first be physically removed, dead mold spores can cause many of the same issues as live mold spores, and the majority of testing does not differentiate between the two.

  2. A product must be used that penetrates several millimeters into the wood or substrate being remediated. This penetration is critical to remove the soil load and the root structure of the mold.  If you just kill what is on the surface, the mold will be back in no time, sometimes worse than before due to the added moisture of remediation.

  3. Mold staining must be addressed.   When mold grows, certain types especially, enzymes are produced that physically discolor and change the appearance of wood.  We use some of the strongest commercially available stain removers on the market.  These stain removers drastically improve the appearance of an attic or crawlspace, occasionally eliminating any trace of a mold issue.

  4.  We put the area being remediated under strong negative pressure, this helps to prevent mold spores and chemical fumes from migrating into living areas.  We chose to go big when it comes to negative air pressure. Our air movement helps to dry the structure during remediation, so dehumidification requirements are less and our customers will be left with a drier home than before we arrived.
