Proper Attic Ventilation

Attics are among the least used parts of our homes. They’re often used as storage areas and are taken for granted. Although it seems far-fetched, attics have a huge influence our living standards, especially in Washington and the Pacific Northwest. Moreover, keeping your attic in good condition can prevent several health hazards as well as structural damage to your house.

In order to keep your attic in good condition, you must pay special attention to its ventilation. There are numerous misconceptions about attic ventilation. There is no specific amount of ideal ventilation because it depends on the size of your attic and shape of your roof, among other factors. If you are in the Northwest part of Washington, your best bet is to contact a professional like Clean Crawls to inspect your attic.  

Attic Ventilation is a Choice

Although having attic ventilation is the best choice, not all homes are designed to have air flowing through the attic. Certain home designs overlook the importance of attic ventilation, so you need to inspect it thoroughly to make sure your house is equipped. Although houses in certain areas can get away with poor or no attic ventilation, it’s crucial to have a properly ventilated house in Washington and the Pacific Northwest.

If you are in the process of designing your dream house, take attic ventilation into consideration. Note that tailoring ventilation systems to complex roof designs is difficult, so make sure you consult with a professional designer and a ventilation specialist.

Ventilating Your Attic Based on Climate

The main purpose of attic ventilation is to regulate temperature in both summer and winter. One of the most common misconceptions is that cold areas don’t require much attic ventilation. It seems silly to allow external airflow into an area you’re trying to keep warm. However, most homeowners don’t realize attic ventilation will help regulate indoor temperature and cut cost on their energy bill.

Proper Attic Ventilation

Ventilating your attic during winter is good because it prevents a phenomenon called ice damming.  Ice damming occurs when snow melts off a roof because the attic is too warm, then freezes again in the gutters. This creates a dam effect and can lead to water seeping in through your roof, causing serious damage to your house. In addition, cold attics prevent heat from raising, keeping the warmth in your house.

Attic ventilation also helps during hot summer days. The constant airflow removes excessive heat and moisture, preventing any damage or elevated energy bills. Poor attic ventilation can result in higher energy costs, damaged property, and even health hazards.   

Problems Caused by Poor Attic Ventilation

Poor attic ventilation leads to countless issues, and you may not even realize what the source is. Professional attic ventilation service providers can help you pinpoint the exact problem and address it efficiently. Poor attic ventilation can cause an array of different problems for you, your family and your house. If you are in the Northwest part of Washington, Clean Crawls can help you prevent the following issues.

Premature Roof Damage

Premature roof damage is among the most common and costly issues caused by poor attic ventilation. Your attic is part of your home’s structure and plays a key role in the durability of your roof. Your roof sits on the rafters, while joists support the ceiling. This helps distribute weight throughout your house's frame. Poor ventilation causes wood and other materials to rot, which can cause irreparable damage to your house’s structure.

Mold and Mildew Build Up

If your attic lacks efficient ventilation, you will end up with excess moisture. This means mold and mildew growing in your attic. The mold and mildew will then spread to the rest of your house, and can cause respiratory diseases and other health hazards. They will also rot away your wood and materials quicker, resulting in double the trouble.

Ceiling Stains

Poor ventilation has visible results all over your house. Ceiling stains are not as bad as mold and mildew, but can eventually lead to unwanted growth of either. If you live in Washington and notice stains on your ceiling or walls, contact Clean Crawls for an inspection and evaluation today.

Harboring Animals

Spiders, cockroaches, and rodents all thrive in moist, dark and warm places. If you have poor attic ventilation you are creating the perfect conditions for an infestation. This leads to higher costs and health issues, and even house damage.

High Energy Bills

Not having a proper attic ventilation system will cause your energy costs to skyrocket suddenly. Better ventilation will help you keep your house warm in winter and cool in summer. Without proper ventilation, your AC and heating units will work extra hours.You should see a substantial drop once you address the poor ventilation issue.
