Today, there are many options to make the roofing on your home energy efficient. Most of these options include using alternatives to asphalt shingles, which can be a costly solution. If you want to use asphalt shingles on your roof, there are some things that can be done to make your roof greener and more energy efficient. This can include using an energy efficient underlayment, choosing lighter colored shingles and adding insulation to the roof rafters. If you want an energy efficient roof with asphalt shingles, here are some things that you may want to consider for your home:
1. Installing An Energy Efficient Underlayment
The underlayment of your roof is usually a type of OSB plywood or 1x6 decking if you have an older home. These materials have a low R-value, which means they provide your home with little insulation. There are newer materials such as foil-backed plywood materials that will give your home more R-value on the roof, and save energy. This is an affordable improvement that you can have done when you have an asphalt roof installed on your home.
2. Using Heavier And Better Performing Moisture Barrier
Besides the structural underlayment, shingles also have a moisture barrier beneath them. This is usually an asphalt felt paper to help prevent condensation from damaging the wood underlayment. If you want more energy efficiency and protection from leaks, using a thicker moisture barrier can help improve your asphalt roof. There are even alternatives to asphalt felt paper, such as membrane roofing membranes that can be used as a moisture barrier.
3. Light Colored Asphalt Shingles For Better Energy Performance
If you want to have better energy performance, using lighter colored shingles can help reflect heat during summer months. These materials can be common shingle colors that are available, or you can even get shingles in white shades to increase these energy benefits. This is a good option for homes in warmer climates that need to reduce cooling costs during the hottest times of the year.
4. Insulating Rafters In Attic Space To Reduce Heat Gain
Attic insulation is an important part of sealing your home to make it energy efficient. Usually, homes just have a layer of insulation on ceiling joists. This allows heat to build up in the attic and reduces the energy efficiency of your home. If you want to be able to reduce heat gain in your attic, in addition to conventional insulation, you can also have the rafters insulated with spray foam insulation to prevent your attic from getting really hot.
