Choosing the Right Roof Insulation

Roof insulation

Your roof is an investment – perhaps one of the largest as a homeowner. When you buy a new roof, you might not consider how insulation impacts your home or energy bills. Our experts will help you choose the right roof insulation of maximized energy conservation.

What does Roof Insulation Do?

Whether you live in a warm, cold, or fluctuating climate, roof insulation impacts how your home transfers heat.

Essentially, insulation addresses the three ways in which heat is transferred throughout your home.


Transfer by radiation occurs when one source acts to heat another. Think of a space heater or fireplace.


Transfer of heat via fibers. For example, when you wear a winter jacket, the heat is stored and transferred to and from your body.


This transfer occurs through the air. For example, through the use of a fan.

Understanding the different mechanisms behind temperature transfer can help you approach insulation from an informed perspective.

Understanding Insulation

Insulation impacts your home’s overall energy performance. The more effective your insulation, the more consistent and low your energy costs.

Roof insulation is important because your roof acts as a barrier to outside weather. When your insulation functions effectively, you can expect less air movement (or loss of heat), dryness (which ensures your roof and home aren’t subject to damaging moisture), and consistent temperatures in your home.

Types of Roof Insulation

You want to select roof insulation based on your home’s design. Homes with sloped roofs have different needs when compared to flat roofs. It is important that you make selections that help to make energy consumption efficient.

When you speak with your roofing company, these types of insulation might be discussed:

Blanket Insulation

Blanket insulation is used in many types of buildings, from residential to commercial. Blankets are available in a variety of materials and thicknesses or easy customization.

Spray Foam Insulation

Spray foam is applied directly to the tiles, slates, or felt. The foam bonds these materials together, helping to keep airflow and temperatures consistent, reduce dust, and prevent rot.

Ridged Insulation Boards

Boards can be made from wood, straw, or cork, which are cut to fit snugly between roof rafters. Boards can be covered, for a more finished look, making them great if you are converting an existing loft area.

When it comes time to select insulation, remember to ask questions about energy efficiency.
