What Does Roof Insulation Do?

Roof insulation is a crucial component of any well-constructed home. Its primary purpose is to provide a thermal barrier between the interior of your home and the outside environment. Here’s how it accomplishes this:

Signs Your Roof Is Poorly Insulated

Now that we understand the importance of roof insulation, let’s discuss how to identify signs that your roof may be poorly insulated:

Temperature Fluctuations:

If you experience significant temperature fluctuations within your home, it could be a sign of inadequate insulation. Rooms may feel excessively hot in the summer or too cold in the winter.

High Energy Bills:

Rising energy bills, especially during extreme weather conditions, may indicate that your HVAC system is working harder than it should due to poor insulation.

Ice Dams:

In colder regions, the formation of ice dams along the roof’s edge can be a sign of inadequate insulation. Ice dams occur when heat escapes from your home, causing snow on the roof to melt and refreeze.

Uneven Roof Surface:

Inspect your roof for areas where snow melts faster than others. This can be a sign of heat loss through the roof due to insufficient insulation.

Mold or Mildew Growth:

Moisture-related issues like mold or mildew growth in your attic or along the ceiling can result from poor insulation and inadequate ventilation.
