Did You Know?

Your attic is no different than your living space when it comes to needing moving air to knock out musty smells and unhealthy particles. When your attic is properly ventilated; air moves freely, reducing heat, moisture, and mold growth.

Your attic temperature should be no more than 20 degrees warmer than the outside temperature. Attics without proper ventilation can reach temperatures of 160 degrees. Reducing the excessive heat allows your HVAC and duct work to cool your home easier and reduce your energy costs.

Most shingle warranties are directly tied to proper ventilation. Although your warranty may still cover manufacturing defects, any damage to the roof system or structure that is caused by inadequate ventilation is not covered by the warranty.

Proper attic ventilation eliminates moisture by facilitating the exchange of air between the attic and the outdoors, effectively controlling humidity levels and preventing condensation. It regulates temperature, preventing the accumulation of warm, moist air that can lead to mold, mildew, and structural damage.

Most Frequently Mistakes

Attic ventilation is essential for maintaining a healthy and energy-efficient home, but there are several common mistakes people make when it comes to attic ventilation. Here are four of them:
1. Blocking or Insufficient Soffit Ventilation:
– Mistake: Many homeowners may accidentally block soffit vents when adding insulation in the attic,
or they may have too few soffit vents to begin with. This can hinder the inflow of cool air into the attic.
– Consequence: Inadequate soffit ventilation disrupts the natural airflow pattern, leading to heat
buildup in the attic, potential moisture problems, and decreased energy efficiency.
2. Overlooking Ridge Vent Installation:
– Mistake: Some homeowners may focus solely on intake vents (like soffit vents) and forget to install
ridge vents. Ridge vents work in tandem with intake vents to create a continuous airflow pathway.
Neglecting ridge vents can result in inefficient ventilation.
– Consequence: Without ridge vents, hot air may become trapped in the upper part of the attic,
defeating the purpose of ventilation and potentially causing problems like overheated roofing materials.
3. Using Powered Attic Ventilators (Attic Fans) Improperly:
– Mistake: Attic fans can be beneficial in some situations, but they must be used correctly. Some
homeowners may leave them running continuously or turn them on when they are not needed.
– Consequence: Running attic fans excessively or unnecessarily can increase energy consumption and
may disrupt the natural airflow balance, leading to inefficiencies and increased energy costs.
4. Neglecting Insulation and Air Sealing:
– Mistake: Attic ventilation should work in conjunction with proper insulation and air sealing.
Neglecting to insulate or seal attic areas can undermine the benefits of ventilation.
– Consequence: Inadequate insulation or air leaks can allow conditioned air from the living space to
escape into the attic. This can result in higher energy bills and temperature imbalances in the home, regardless of attic ventilation.
To ensure that your attic ventilation system works effectively, it’s advisable to consult with a
professional roofing contractor or energy specialist. They can assess your specific needs, recommend the right combination of ventilation components, and ensure that insulation and air sealing are properly addressed to create a well-balanced and energy-efficient attic environment.

Facts About Moisture:

The amount of moisture produced by a family in a home on a daily basis can vary significantly depending on various factors, including the number of occupants, daily activities, and the climate. On average, a family of four can produce between 2 to 4 gallons (7.6 to 15.1 liters) of moistur

Breathing:

Each person exhales moisture when they breathe. On average, an adult breathes out about 1 to 2 pints (0.5 to 1 liter) of moisture during sleep.

Cooking:

Cooking generates moisture through the boiling and steaming of food. The amount can vary widely depending on the type and frequency of cooking.

Showering and Bathing:

Showers and baths are significant sources of moisture in a home. A 10-minute shower can release about 1 to 2 pints (0.5 to 1 liter) of water vapor into the air.

Laundry:

Running the washing machine and dryer can release additional moisture into the indoor environment, especially if the dryer is not properly vented.

Houseplants:

If you have indoor houseplants, they also release moisture into the air through a process called transpiration.

Humidifiers:

If you use humidifiers to increase indoor humidity during dry seasons, this can also contribute to moisture levels.
The climate in which you live plays a significant role in how moisture affects your home. In colder climates during the heating season, indoor air tends to be drier, so the moisture produced by daily activities may not cause as many issues. However, in more humid climates or during the cooling season when air conditioning is running, excess indoor moisture can lead to problems like mold growth and reduced indoor air quality.

To manage indoor moisture levels effectively, it’s important to use exhaust fans in bathrooms and kitchens, ensure proper ventilation, use a dehumidifier if needed, and take steps to prevent
condensation on windows and walls, especially during colder weather. Proper insulation and sealing of your home can also help control moisture and maintain a comfortable and healthy indoor environment.

Signs of problem ventilation, (ignore winter ones) Inadequate attic ventilation can lead to a range of problems in your home. Here are some common signs that your attic ventilation may not be working properly:

High Energy Bills:

One of the primary purposes of attic ventilation is to regulate the temperature
in your attic. If your attic is too hot in the summer or too cold in the winter, it can strain your home’s HVAC system, leading to higher heating and cooling costs.

Excessive Heat in Attic:

During hot weather, if your attic feels excessively hot when you enter it, it’s a sign that heat is being trapped rather than properly ventilated. This can potentially cause damage to roofing materials and reduce their lifespan.

Mold or Mildew Growth:

Poor attic ventilation can result in higher humidity levels in the attic,
promoting the growth of mold or mildew on the wood surfaces, insulation, or roof sheathing. If you notice a musty odor or visible signs of mold in the attic, it’s a clear indication of ventilation issues.

Roof Problems:

Improper ventilation can lead to problems with your roof, including premature deterioration of shingles, warping of the roof deck, and even ice dams in cold climates. Insufficient ventilation can cause these issues by allowing excessive heat buildup in the attic.

Uneven Temperature Distribution:

If you have rooms in your home that are significantly hotter or colder than others, it could be a result of poor attic ventilation. Hot air trapped in the attic can radiate down into living spaces, making them uncomfortable.

Water Stains or Leaks:

Inadequate attic ventilation can contribute to moisture problems,
including roof leaks. Water stains on the ceilings or walls below the attic may indicate that moisture is entering the home.

Excessive Ice Formation:

In cold climates, ice dams can form on the roof’s eaves due to poor attic ventilation. If you consistently have large icicles or ice dams forming, it’s a sign that heat is escaping from the attic and melting snow on the roof, which can lead to water damage.

Premature Roof Aging:

If your roof materials, such as shingles or underlayment, deteriorate
faster than expected or have a reduced lifespan, it may be due to inadequate attic ventilation allowing excessive heat buildup.

Warped Wood or Truss Damage:

Over time, improper ventilation can lead to structural
problems such as warped roof decking or damage to attic trusses due to moisture and temperature fluctuations.
If you observe any of these signs, it’s essential to address your attic ventilation issues promptly. Consult with a professional roofing contractor or an attic ventilation specialist to assess the situation and recommend appropriate solutions to ensure your attic functions as intended.

Amount of Ventilation (this excludes the 1:300 rule which requires proper placement of exhaust vents):

The amount of attic exhaust and intake ventilation you need depends on several factors, including the size of your attic, climate, and the type of roofing system you have. A general guideline to follow is the ”1:150” rule, which suggests that for every 150 square feet (14 square meters) of attic space, you should have 1 square foot (0.093 square meters) of net free ventilation area. This is typically divided between intake and exhaust vents.

Here’s a breakdown:

1. Intake Vents: Intake vents are usually located at the soffit or eave areas of the roof. They allow fresh, cooler air from outside to enter the attic. You should aim for roughly 50% of the total ventilation to be intake vents. So, for every 150 square feet of attic space, you would need approximately 0.5 square feet (or 72 square inches) of net free intake ventilation.

2. Exhaust Vents: Exhaust vents are designed to expel warm, moist air from the attic. These can be ridge vents, gable vents, or other types of vents. The remaining 50% of the total ventilation should be exhaust vents. Therefore, for every 150 square feet of attic space, you should also have approximately 0.5 square feet (or 72 square inches) of net free exhaust ventilation.

It is important to note that these are general guidelines, and your specific attic may have unique
requirements. Factors like roof design, local climate conditions, and the presence of additional ventilation mechanisms (such as attic fans) can affect the balance of intake and exhaust vents.

It is advisable to consult with a professional roofing contractor or an attic ventilation specialist to determine the precise ventilation needs for your home. They can perform a thorough assessment and recommend the most appropriate combination of intake and exhaust vents to ensure effective attic ventilation.
