Proper Attic Insulation: How Does It Benefit Your Roof?
Attic insulation is a key aspect of your roofing system. How well your roof performs involves far more than shingles. It requires an entire system to maximize both performance and durability.
That includes insulation and ventilation. Then, all these elements work together to maintain the comfort of your home. Moreover, they help in the following ways.
- Increase the lifespan of your roof
- Save you money on cooling and heating
- Reduce the emissions of greenhouse gas
How Ventilation & Insulation Improve Your Roof
When you combine proper attic insulation with a solid ventilation system, it helps to keep excessive moisture and heat out of your home. Moreover, it helps to maintain the right conditions in your attic and on your roof all year long.
If your home lacks this combination, the heat and moisture trapped in the attic have the potential to cause serious damage to your home and roof. Consider the following examples.
- Ice dams forming to prevent water runoff
- Interior damage
- Metal rust on the nail heads
- Mold, fungi, mildew, and spores
- Premature failure in your roof materials
- Wet wood that causes the roof to sag
How Attic Ventilation Works
The purpose of proper attic ventilation is to remove the hot, stagnant air and excess moisture from your attic. Additionally, it keeps the interior of your home properly conditioned. Like attic insulation, ventilation is a key component of a high-quality roofing system.
It helps to keep the air in your home at a more comfortable temperature. Moreover, it enables a natural, consistent airflow, managing the moisture and temperature of the attic.
In colder temperatures, proper ventilation prevents the formation of ice dams and frost buildup. When we have those hot Texas summers, it minimizes the temperatures and moisture levels in the home.
How Attic Insulation Works
Generally speaking, heat flows from warm spaces to cold areas until the temperature is the same. In the winter, this means the heat leaves your home toward unheated spaces. For instance, this includes your attic, the garage, your basement, and even the outdoors.
The insulation in your attic offers resistance to the flow of heat to other areas. As such, it keeps the interior heated while preventing the heat from flowing to cooler areas. In the summer months, this works in reverse, keeping the outside heat from entering cooler spaces.
Should I Insulate My Attic?
Typically, adding insulation to your attic is a good idea. It helps your roof, your budget, and your planet. The insulation in your attic is one of the most effective ways to reduce your home’s greenhouse gas emissions.
Save Energy & Money
Did you know? Up to 40% of the air leakage in homes goes through the attic floor?
That means your cooling and heating costs quite literally go through the roof. If this is the case for you, it’s a good idea to add attic insulation and seal the attic floor. This helps to cut your cooling and heating bills by up to 15% in some cases.
However, it is crucial to identify and address air leaks first. If you simply toss insulation into a drafty attic, it won’t work quite as well.
Generally, the air inside homes contains quite a bit of moisture. This can be trouble for attics. That’s why it’s important to seal cracks and joints to prevent the escape of air into the attic.
Additionally, keep an eye out for dark spots on the roof and water stains in your rafters. These point to possible leakage points. When you notice these signs, it’s a good idea to call on a professional roofing company to check on your roofing system.
