How mold grows in an attic

The whole point of insulation in the attic is to help heat stay in your house, so that it doesn’t reach the roof. If your attic insulation works properly, it prevents the radiant heat from your home from escaping through the roof. 

With a properly installed vapor barrier and thick, deep insulation, any moisture from the house stops in its tracks before it hits the attic. Moisture is the breeding ground for mold, so ensuring a dry attic space is paramount to mold prevention.

Mold in the attic typically forms on top of the insulation surface, not below it or embedded in mounds of sprayed fibers. Here’s how that happens. (Hint: it’s not what you may assume.)

When moist air from your attic meets cool or cold roof sheathing, condensation occurs. Mold grows in moist areas, but cannot gain a foothold without a food source. Since most attic insulation does not “feed” mold, any spores that grow likely come from the roof sheathing instead. 

If you see mold spores on the surface of your insulation, they probably dropped in from the roof sheathing. Of course, an inspection will tell you if your attic mold is more systemic than on the insulation surface.

Treating mold in your attic

Once you determine the source of the mold spores in your attic, remediation can be relatively simple. If you discover mold spores on the roof sheathing, that’s where you’ll focus your cleaning efforts.

Applying a mildewcide to any mold-covered areas on the roof kills the spores and can prevent new ones from forming. You can usually apply the same chemical to the insulation surface to kill any active spores.

Here’s some good news. Mold and mildew in the attic typically don’t pose a threat to your health. Why? Because the “stacking effect” of your attic insulation prevents surface mold from migrating into the rest of your home.

So, once you’ve treated the mold source, you may not need to replace any insulation. If you have extensive mold in your roof, and consequently, a thicker coating of mold on your insulation, you may decide to replace it.

A full insulation clean-out is certainly an option, but you could potentially choose to replace the top couple of inches of fibers only.

Remember, it’s crucial to keep the materials surrounding your insulation mold-free to ensure a pristine insulation surface. 

Reducing moisture in the attic

If you discover mold on your roof sheathing, you can take several measures to dry out your attic and reduce the potential for mold and mildew.

    1. Clear all attic vents. Improper installation and settling may cause attic insulation to block the vents in your attic. Proper air flow is paramount to maintaining a dry, mold-free environment. Ensuring your attic vents remain unblocked with regular checks can help you avoid the moisture that grows mildew.
    2. Ensure proper levels of insulation: Having a “just right” amount of attic insulation is an essential piece of your ambient attic humidity and temperature. Too much or too little can create conditions ripe for condensation to occur.
  • Seal all bathroom and kitchen vents into the attic. Since bathroom and kitchen air is notoriously moist, you must make sure to seal it off from attic air. In fact, new building standards recommend restricting the use of bathroom and kitchen vents through the attic. To ensure that warm moist “home” air does not mix with cooler attic air and condensate, fewer holes between the two environments make sense.
  • Inspect and maintain your roof. Since your roof is your first line of moisture defense, a leaky one isn’t doing its job. Visually inspect your roof each season for items like curling shingles, rotted fascia boards, large and small debris, and visible holes. Pay close attention to the seams around chimneys and skylights, as those are prime spots for leaks to develop. Of course, you’ll also want to check for water damage on the walls and ceilings of your home. It’s a good idea to have a professional help you inspect your roof completely and safely. You should check your roof each year, and after severe storms. You’ll also want to keep an eye out for ice dams during the winter months.
  1. Install a dehumidifier. Once you’ve addressed all of the structural prevention measures for mold and mildew in the attic, you can keep your space dry as the seasons dictate. During an especially wet spring or summer, a dehumidifier can help ensure that conditions don’t deteriorate in your attic.

Save Money with Attic Insulation

When it comes to protecting your home, ensuring that you have adequate attic insulation is vital. We all know how this can help keep your home safe and secure, as well as regulating temperature. Did you know, however, that you could also save money with attic insulation?

Taking time to ensure that your attic insulation is top quality can reap significant financial rewards down the line. Read on to see how you could save, and the benefits to your everyday life!

Reduce your utility bills.

Energy bills are a great way to save money with attic insulation, and play a crucial part in saving cash. The average home spends between 50% and 70% of its energy on heating and cooling – insulation can really help.

The main area to prioritize here is the attic space. If this area is under-insulated or lacks insulation, you will need to spend more regulating temperatures.

Research shows homeowners can enjoy a saving of 15% of heating and cooling costs. This can be achieved simply by ensuring that your attic is adequately insulated. Depending on your lifestyle, family size, home, and heating system, this could equate to savings of $780 per year.

Maximize the efficiency of your systems.

You could also save money with attic insulation by improving the efficiency of heating and cooling systems. Even modern homes, with top-quality systems, can suffer from fluctuations in temperature if they are not adequately insulated. Temperatures may change drastically between floors, or suddenly become very hot or cold, at the slightest change in temperature outside.

If you notice a difference in temperature of between 10 and 15 degrees between floors, take this as a warning. Such a significant difference is a sign that your insulation is inadequate. Heat rises to the top of the house – usually to the bedrooms.

As a result, you are more likely to spend time and money trying to cool these rooms. Over the year, this can seriously increase your energy bills.

Older homes are also important here if you are looking to save money with attic insulation. By their very nature, these structures tend to be draughtier, with cracks and crevices for energy to escape.

As a result, your heating or cooling equipment will have to work twice as hard to keep the temperature consistent. If the ductwork in your home runs through the attic space, this can also have an impact.

Poor insulation here will also prevent the heat from being transported evenly through your home. This can then result in temperature disparities between levels. 

The less efficient your insulation, the harder your equipment will have to work. The increased wear and tear can cause your unit to wear out more quickly. Replacing the system time and again can prove expensive. Increased pressure can also result in breakdowns as the HVAC works harder; again, these costs can quickly add up.

Keep your home safe, reducing long-term costs.

Another way to save money with attic insulation is to reduce your outgoings. Insulating your attic helps reduce energy bills, but it can also improve general safety and security. 

Heat and moisture can damage your home when allowed to build up over time, as water vapor erodes the walls. Eventually, this can result in damp and mold issues, both of which thrive in moist, dark, cool spaces.

If your attic is allowed to get too hot, this can cause swelling and cracking to shingles on the surface. An attic that is at the wrong temperature also allows ice dams to build up and form.

These occur when snow melts and then refreezes on the edge of the roof. Over time, this leads to a build-up in pressure and can cause serious structural damage to the roof.

The cost of replacing the entire roof is not insignificant. Even smaller repairs such as tiles and shingles can add up over time. By keeping your roof at the optimum temperature, you reduce the risk of these issues. An investment now has the potential to save you money on expensive repairs.

Pests and animals may also enter your home through poor insulation, and can do a lot of damage. They may create nests, leave behind droppings (or guano) or cause structural problems. High-quality insulation helps remove their point of entry and can keep the attic space more secure.

Improve air quality

Many of us spend a great deal of money on air purifiers, in an attempt to keep our air fresh. There is another solution. However, investing in good quality insulation can help achieve this goal for a lower overall price.

Poor insulation often contains cracks and gaps, and these can allow pollutants from outside to enter the home. Dust, mildew, dirt, and mold, can all make their way into your home, along with any number of airborne toxins. Over time, this can have a detrimental impact on the health and wellbeing of your family.

While dedicated air purifiers can really help with this, they can be very expensive to run on a daily basis. If you require constant refreshing and purification, the costs can add up. Secure, durable insulation can, however, lock down any gaps and prevent leaks.

In turn, this will remove the space for pollutants to enter, allowing easier breathing and cleaner air for everyone. A great way to stay healthy while allowing you to save money with attic insulation.
