Proper roof insulation is one of the best ways to improve your home’s energy efficiency and lower utility bills. Insulation creates an effective barrier between the inside and outside of your home, reducing heat transfer.
The type and amount of insulation you need depends on your climate and home specifics. For most homes, the attic and exterior walls are good places to start. Adding insulation to your attic can make a big difference in energy efficiency.
Proper insulation and an energy-efficient roof can significantly improve the comfort of your home while lowering energy usage and costs. Combined with sealing air leaks, these are some of the best ways to ensure maximum efficiency and savings for your most valuable asset.
There are several types of insulation you can install in your attic or under your roof to improve energy efficiency. The best option for you depends on your climate and budget.
Fiberglass batt is a popular, affordable choice. It comes in rolls that you place between the joists in your attic. Fiberglass works by trapping air to reduce heat transfer. It’s best for temperate climates.
Loose-fill or “blown-in” insulation, like cellulose or fiberglass, is another budget-friendly option. It’s made of small particles that are blown into your attic space. Blown-in insulation conforms very well to the attic space and reduces air leaks. It works for most climates but may settle over time.
Foam board insulation provides high R-values for its thickness. Types like polyisocyanurate (polyiso) and extruded polystyrene (XPS) are moisture-resistant and work in any climate. However, foam board is more expensive than fiberglass or cellulose and can be difficult to install yourself. It’s often used for roof panels and sheathing.
Also known as high-density polyiso cover boards, these rigid panels provide an effective thermal barrier for your roof. They are made from materials like polyisocyanurate (polyiso) that don’t absorb moisture and have an R-value of at least R-6 per inch of thickness. The panels are installed directly under your roofing material.
This is a great option if you want to fill in small cracks and crevices. Spray foam insulation is made from polyurethane materials that expand and harden, sealing and insulating the area. It has one of the highest R-values per inch, around R-6 to R-7. Spray foam also helps reduce air leaks, drafts, and condensation in the attic. However, it typically costs more to install compared to other types of insulation.

When it comes to roofing, you have several options to improve your home’s efficiency. The type of roofing material you choose can impact the amount of energy required to heat and cool your house.
A metal roof, like aluminum or steel, reflects sunlight and can lower your cooling costs by up to 25%. Metal roofs can last 50-70 years and are ideal for rainwater collection. However, they may dent or scratch more easily and can be noisy during rainstorms.
Tile roofs, such as clay or concrete, also offer good insulation and can last 50 years or more. Tiles come in a variety of styles to suit your home’s architecture. However, tiles are heavy, so you need to ensure your roof can support the weight, and they may crack more easily in very cold weather.
Asphalt or composition shingles are affordable and energy efficient, lasting 15-30 years. Lighter colors will reflect more sunlight in warm weather. Asphalt shingles are versatile but may not withstand high winds as well as other materials.
