Energy Conservation Starts With Your Roof

Nobody wants to pay sky-high energy bills. But unfortunately, a lot of common energy-saving tips – like turning off lights when you leave a room and turning the thermostat down a few degrees – will only save you so much. Energy conservation really starts with your roof, since a lot of heat can be transferred through this sky-facing surface of your home. Here's a closer look at why your roof is so important for keeping energy bills in check, as well as a look at some of the things you can do to make your roof more energy efficient.

Why is your roof so important for energy conservation?

Hot air rises. In the winter, this means that the warm air on your home naturally gravitates towards the highest floor in your home and is in a position to be drawn out through your attic and roof if something does not stop it. A well-insulated, well-sealed roof will keep this heat in, but a worn-out, poorly insulated roof will just let it escape.

In the summer, the hot sun shines down on your roof, warming it up considerably. If your roof is not well insulated, this heat will be transferred right into your home, leading to higher AC bills and a warm second floor.

How can you make your existing roof more energy-efficient?

Make sure your current roof is well-insulated. An online insulation calculator can help you figure out how much insulation you need, according to your zip code. If you don't have as much as is recommended, you can add another layer. Another option is to replace your fiberglass insulation with spray foam insulation. Spray foam adheres directly to the inside of your roof surface, forming a solid barrier. This means that it not only prevents heat transfer, but also prevents air from blowing through.

You can also increase the efficiency of your existing roof by having it sprayed with a cool roof coating. These are light-colored coating that help reflect sunlight so that it has less of a warming effect in the summer.

Finally, make sure your roof is kept in good condition. If shingles blow off, have them replaced immediately so that water does not penetrate into the deeper wooden portions of your roof and cause rot. Once these structures start to rot and break down, they make it easier for heat to be transferred through your roof, leading to increased energy bills.
