Attic Insulation: Why It’s Good for Your Roof

The health of your roof hinges on more than just high-quality shingles. In fact, a well-insulated attic can also maximize the durability and longevity of your roofing system. Proper attic insulation not only protects your home against heat loss but also preserves your roof’s structural integrity. State Roofing, one of the leading contractors in the state, provides an overview of why attic insulation is good for your roof. 

Attic Insulation

How Does Attic Insulation Work?

Heat travels from warmer to colder areas until the temperature is the same in both places. In the winter, for instance, heat flows from heated indoor spaces to adjacent unheated areas such as your attic, basement, garage and the outdoors. Insulation provides effective resistance to the flow of heat to other areas. It helps keep your interior rooms warm and prevents heat from traveling to cooler spaces. In the summer, insulation controls airflow and contains indoor cool air. 

Without sufficient attic insulation, excess heat escapes through gaps in the cracks and ends up in your roof’s peak, trickling through your shingles and roof deck. If you have proper insulation throughout your attic, the wood structure under your roofing system will be less affected by changes in outdoor temperature.

What Are the Benefits of Proper Attic Insulation?

We list a few examples of the benefits of quality insulation in your attic:

  • Preserves roof structure. Poor attic insulation can cause water damage, rot and cracking in the long run. Wooden rafters, for instance, are more susceptible to expanding and contracting because of temperature changes, which can lead to cracks. As such, you need effective attic insulation to keep your home warm while also preserving roof structure. 
  • Reduces leaks. Leaks can put your home at risk of developing issues such as mold and wood rot. A well-insulated attic can reduce the likelihood of leaks by providing an extra layer of protection. If your attic doesn’t have proper attic insulation, your roof ends up with gaps or cracks where water can seep in. 
  • Protects roof shingles. Due to the temperature changes throughout the year, roof shingles can become warmer at times and freeze at other times. This can lead to cracks or brittleness. To prevent this, you need an attic with plenty of insulation. This way, you protect roof shingles from the effects of temperature changes and make it easier for shingles to maintain more even temperatures regardless of the weather.
