Your Roof and Attic: Key To Your Home’s Energy Efficiency

Energy efficiency tips - roof and attic

When it comes to your home’s energy intake, so much of what we spend our money on is in keeping the indoor temperatures within a certain range.

Did you know that just the color of your roof can change the surface temperature of your roof by 50 degrees?

Homeowners and business owners may not think much about their roofs when calculating energy costs. However, by following these tips, you can save a bit of your hard-earned cash.


One thing that will save you money no matter what season is to check out your attic insulation and make sure you have a sufficient amount. In winter months, you want to have a cool attic – that is, an attic with cool air.

If your attic is warm, that means warm air is escaping upward through your ceilings and improperly insulated attic floor. You are paying to heat that unused space, and warm air is most likely also getting out through your roof and potential causing ice dams.

Insulation also works in the summer months. It acts almost in reverse, assuming your attic is vented properly, helping keep the hot attic air from passing into your living space.

Of course, proper home maintenance in all seasons will keep indoor temperatures comfortable: weather stripping, caulking, sealing ducts, and replacing furnace filters regularly. In addition, make sure you have an annual roof inspection to check for damage or wear and tear.

Cool Roof

There are several ways you can get a cool roof. One of them is by choosing a lighter color of roofing material. This is especially true in warmer climates, but Michigan has its fair share of hot days in the summer that can drastically increase your energy spending even in summer months.

 A light color absorbs less of the sun’s heat and reflects more of it back. In commercial flat roofing, white material is much preferred over black for this reason.

Another way to increase your roof’s reflective capabilities is by applying a reflective coating. Many roofing materials have reflective granules.

Be sure to ask your contractor about your most energy-efficient options when you are looking at replacing your roof.

Materials for Energy Efficiency  

A reflective coating is one of the best and most cost-effective ways to increase the energy efficiency of your roof. Asphalt shingles without reflective coating will absorb up to 75% of heat beating down on them by the sun.

By contrast, a good coating can help those shingles to reflect up to 80% of what they get. The coating also makes shingles stronger and more durable.


If you like many other home and business owners are bemoaning the energy losses of this winter season – or you are remembering that it’s not much better in the summer months either – these simple tips for energy efficiency should be a good starting point toward making your home or building more efficient.

Make sure you are doing simple maintenance twice every year on your whole building, have a roof inspection, and make sure you have the right materials installed correctly.
