Preventing mold growth and proliferation in your attic is a simple task if the proper time and effort is put into the process. There are two different things that you should check to ensure that your attic is as protected as it can be.
Roof: Check your roof for leaks; some are easy to spot with marked discoloration of the insulation and warping accompanied by discoloration of wood. Any place that two materials meet such as roof valleys, skylights, chimneys, windows etc. are all susceptible to leaking if not properly joined or sealed. Check around the perimeter of each in your attic and look for signs of leaking. If you find any leaks, take immediate action to handle the situation.
Ventilation: Poor ventilation can cause a moisture problem especially due to two of the most common culprits: improper vapor barrier installation and insulation covering vents. As moisture travels up to the attic from normal everyday activities of cooking and taking showers, it needs to be able to escape. Proper ventilation allows the moisture to escape quickly and not settle in the attic.
Taking the time to do a thorough check of your attics roof and vents is definitely worth it in the long run. If you don’t feel comfortable checking the attic, or find signs of mold growth that you’re not sure how to handle, contact an expert. The sooner that you handle moisture issues or combat existing mold issues the better!
