Attics have all the things mold needs to grow: food (drywall, cardboard boxes, leather goods, etc.), oxygen, the right temperature, and moisture. Humidity higher than 60% gives mold a perfect environment in which to grow. The good news is you can prevent attic mold from causing problems. Controlling moisture levels stops mold growth in its tracks.
Where Did the Attic Mold Come from?
Molds grow from microscopic spores that are everywhere in the air. Molds are found everywhere in nature, including your attic, and are important for recycling organic matter (such as leaves). The recycling process they perform returns nutrients to the soil and is important for plants to grow. Molds need four things to grow: oxygen, moisture, a food source, and the right temperature range.
Food Sources
Molds grow inside of their food sources. They penetrate deeply into wood, insulation, drywall, carpets, underneath kitchen and bathroom sinks, etc. Anything with carbohydrates in it could be considered a food source for molds.
Moisture
Moisture is the one thing you can reasonably control when it comes to mold. A dry home equals a home with less mold growth. Keeping areas dry, especially areas that use water frequently (like bathrooms), is important to prevent mold growth.
How Fast Do Molds Grow?
Once enough moisture is present, molds can begin to grow in less than 48 hours! Water from leaks, condensation, and poor ventilation can cause a ticking mold time bomb.

How Do You Know if You Have Attic Mold?
Have you been up in your attic lately? Most people never venture into this part of their homes. Attics can easily be infested with mold for 2 primary reasons – poor ventilation and roof leaks.
Roof Leaks
One of the most common causes of mold in the attic is a leaking roof. To check for possible roof leaks, look for discoloration of insulation and wood including: the rafters, sheathing, joists, fascia boards, roof valleys, skylights, chimneys, windows, flashings, and the like. While you’re up there, make sure there are no leaks around attic plumbing stacks or air conditioners. If you have a vapor barrier, check for condensation.
Roof penetrations are one of the most likely places to find leaks. At least twice a year, roofs should be checked for leaks. Attic mold is often caused by the buildup of moisture that can not escape. One easy way to tell if you have excessive moisture in the attic is to look at the nails. If they are rusted, you most likely have moisture and ventilation problems. Black spots and discoloration can also signify a leak and means trouble.
Check that caulking and flashing are secure and in good shape. Repair missing or loose shingles, damage from limbs and remove any moss. While you are on the roof (or your chosen repair technician is), be sure to inspect the chimney for loose bricks, or boards. Also, check that the flashing is secure, and that no water is passing through it. Be sure a chimney cap is installed and working properly.
Poor Ventilation
The old attic vents were covered by the new roof. The roofers did not install new vents. Mold was the result.
Because air travels upward toward the attic, household activities such as cooking, bathing and showering will produce moisture that can make its way to the attic and become trapped. Rusted nails and discoloration of wood are clues that there is too much moisture in the attic.

Why Proper Attic Ventilation is Important
Proper roof ventilation is very important in keeping your attic dry and mold free. Most homes have a passive system to circulate air through the attic. Around the ridge of your roof are soffit or eave vents that allow external air to enter the attic. This air then warms up in the attic, and leaves through can or ridge vents because heat rises. The process of air moving through the attic creates a well ventilated space, and prevents moisture and heat from being trapped.
However, when air is unable to enter or leave the attic, moisture and heat build up and encourage mold growth. If the soffit or eave vents are blocked (by paint for example), fresh air cannot enter the space. If the ridge vents or can vents are blocked (or not present), moisture and heat can build up in the space with nowhere to go. We have visited homes with mold and moisture problems where there were no ridge or can vents and others where there were soffit or eave vents were blocked. Never assume these things are in place and working properly! Be sure to include checking these vents as part of your home maintenance routine.
Bathroom fan vented into the attic instead of outside the home. The moist air is causing mold growth.
Other Types of Improper Ventilation
Other types of improper ventilation can also cause moisture problems. Improper ventilation of bathroom fans or dryer vents into the attic space can increase moisture and heat in the attic.

Does Attic Mold Affect Your Health?
In one word…Yes.
Mold is an insidious, invisible predator in your home. It hides in places no one ever thinks to look like under cabinets, in crawl spaces, attics, and behind furniture. People may spend weeks, months, and even years fighting illness, and never know what they are really fighting…mold. Many of our customers find us after a recommendation from their doctor, that they may in fact have a mold problem, and not just an illness.
Mold is most often associated with allergies, but mold is much more menacing than people know. While all molds have the potential to cause irritation and allergy symptoms, molds can also cause much more dangerous health problems including: fungal poisoning and mental health problems. You can learn more about mycotoxin poisoning in our article: When Mold Is Worse Than Allergies.

What Are The Steps Of Attic Mold Removal?
When you have a mold remediation company come to your home, you need to know just what to expect. There are 5 steps to attic mold removal or remediation.
Define The Scope
This begins with an Indoor Air Quality Assessment. Your inspector will define the extent of the necessary work and what may or may not need to be done. The inspector should talk you through all your options and tailor a plan that fits your needs and your budget.
Protect The People
Keeping your family and the work crews safe is top priority. This means preparing your home for the work that needs to be done. Branch Environmental uses methods such as containment walls and negative air to keep your home safe, and we’ll let you know if you can or cannot be in the home during the work. Check out our post Branch Environmental Keeping You Safe to learn more.
Correct Moisture Problems
Roof leaks are not always this dramatic. Small leaks over time can be just as damaging.
Removing or correcting the source of moisture is a vital part of the remediation process to ensure mold does not return. This may be handled by a contractor outside the scope of the mold remediation. Once walls or floors are opened up, now is the time to address plumbing issues and other leaks. Leaks are problems that can be remedied quickly if routine maintenance checks are performed on your home. The longer a leak is present, the more mold will grow. Prevention is worth nine tenths of the cure they say!

Remove The Mold
The work will start by removing and discarding non-salvageable material. Next, the materials that can be saved are cleaned. At Branch Environmental, we always use safe and environmentally friendly products. There is no reason to replace one environmental toxin with another, such as bleach. Be sure to ask your mold remediation contractor questions about the chemicals they use to remove mold and if they are environmentally friendly.
Restoration
If walls, floors, or ceilings were removed during the remediation, the final step will be reinstalling what was taken out. Drywall, carpet, and other soft materials are the most likely materials that will have to be replaced. However, even framing or complete ceilings may have to be replaced depending on the level of damage.
This Sounds Expensive!
Most people rarely plan for the expense of mold removal, so here at Branch Environmental, we are careful to help control costs and manage your expectations from the beginning. With a clear understanding of the problem, we can work with you to create a remediation protocol that fits your needs.
The best place to start is with a paid Indoor Air Quality Assessment. This step will give you all the information you need to move forward. You will discover exactly how extensive your problem is, and what is necessary to solve it.
