Make Sure You Have an Energy Efficient Roof
Want to make sure you have an energy efficient roof?
Here are some tips for improving your roof’s energy use here in the Boise area.
According to the U.S. Department of Energy, heating and cooling make up 48 percent of the total energy use in a typical U.S. home. That makes heating and cooling the most expensive energy cost for most homeowners.
Here in Boise, and the greater Treasure Valley, homeowners have not only been fighting high temperatures with A/C in the summer, but will soon be cranking up the heat as fall sets in and winter approaches. We can expect snow storms here in Idaho which makes it important to ensure your roof can withstand the cold elements. However, your roof should also serve as one of the most critical components to making your home energy efficient.
This winter, you might try your hardest to keep the heat in by doing things like sealing windows, but your roof can be responsible for about 20 percent of heat loss. Thus, it’s important that you make sure it’s as energy efficient as possible.
Roof changes that make a difference
An energy efficient roof means it’s equipped with insulation. Your attic and roof should be professionally insulated to ensure that your home has the tools to adjust to the changing seasons. Older homes are commonly built with less insolation than newer homes. This padding will help prevent heat in the summer and cold in the winter from entering through your roof so easily.
Insulation is measured in R-values, this value represent the thickness or depth in inches of the insulation you have. If your attic insulation is less than R-30, your energy bill could probably benefit from more insulation or a different type.
If your roof is damaged, this can cause obvious losses in energy and repairs should be made. If your roof needs replacing, consider replacing it with a more energy efficient material. Replacing deteriorated roofing with new asphalt roofing can made a big difference. However, synthetic slate or metal are great alternatives to asphalt here in the Boise area. Metal roofs can help reflect that blaring August sun during the summer.
Unfortunately, no one has invented or found a material that is fully reflective in the summer and fully absorbent in the winter. However, there are materials available that have high thermal mass. This means it takes longer for the material to absorb heat in the summer and longer for the material to release heat in the winter. Synthetic slate is a great high thermal material option. Though you may hear about energy efficient ‘cool roofs’ from California friends, here in the Treasure Valley cool roofs are not as efficient because of our seasonal weather which includes freezing temperatures in winter. Cool roofs are designed to release and reflect heat efficiently which is great for year-round warm weather, but can add to winter energy bills for Boise homeowners.
