⭐ Attic Mold Indicators

  • Another big indicator of the mold are the raised shingles. If you happen to observe raised shingles then these are a clear sign that somewhere in your space, mold has started spreading its tentacles. Usually the place is attic, as it is mostly unused and hence the closed space invites dampness which leads to mold growth.
  • Roof leaks are the number one reason behind mold growth. A rooftop spill is a certain method to promise that you will have to face the mold issue. Look out for discoloration at roof, especially near joints, as these are the most vulnerable points of the roof. If you come across as any discoloration, you should repair or swap the piece immediately even a slight delay could cause problems.
  • Any holes in the attic should be plugged carefully, as the seepage from these holes could make a way for the water, which would then accumulate in the attic. This dampness would later create favorable conditions for mold. Attic mold is usually the result of seepage and hence home owners must pay special attention to the ventilation and piping of their homes.
  • Mold growth in attic can easily be suppressed through proper ventilation. This is perhaps the easiest of fixes for mold growth and all you need to do is ensure proper ventilation. Since air movement stops the way for dampness therefore you must pay special attention to attic ventilation.
  • Don’t forget to check ventilation from warm air sources, as the air circulation of warm and cold air has to be in complete equilibrium in order to ensure proper ventilation. Warm air vents should be kept outside the main structure so that the inner environment could be saved from dampness.
