Energy efficiency is not only good for the environment, it's good for a homeowner's wallet as well. Increasing the home's energy efficiency can lead to lower energy bills and can mean big savings over time. The roof is one area where energy efficiency can be improved. Roofers can achieve increased energy efficiency by making a few small changes when repairing or re-roofing the home. Here are three ways to get a more energy efficient roof.

Create A Cool Roof

The term cool roof may be a little confusing to some homeowners. Cool roofs are lighter in color than traditional dark shingles and because of their lighter color they are able to reflect heat and light away from the home. This leads to a cooler roof temperature and increased energy savings. The easiest way to get a cool roof is by having roofers apply a cool roof coating or sealant to the roof. This is easier and less expensive than replacing existing shingles. The cost of coating a roof ranges on average between $337 and $1,345.

Pump Up The Insulation

Not enough insulation near the roof can mean much higher heating and cooling costs. The proper place to add more insulation will vary depending on the design of the home. However, in most cases, adding insulation to the attic directly below the roof can make a big impact. Roofers can help homeowners determine which type of insulation will make the biggest impact on their roof's overall energy efficient. The average cost to re-insulate an attic ranges from $1,300 to $2,000 and sealing and insulating the roof itself costs on average $1,500. 

Get A New Roof

The average lifespan of a roof can vary greatly depending on the material used. Asphalt shingles tend to last between 15 and 25 years, slate and concrete tiles between 50 and 100 years, and some metal roofs can last over a century. If the roof is near the end of its natural lifespan or in poor shape, a full roof replacement may be the best option. Roofing contractors can help homeowners determine which material will be the most energy efficient for their climate. Light colored cool roofs, metal roofs, and concrete tile roofs in particular are known for their energy efficiency. The average cost of a new roof can vary greatly depending on the material used and the size of the roof. Asphalt is often the least expensive costing $120 to $400 per 100 square feet while slate, tile, and metal often cost more than $1,000 per 100 square feet.

Energy efficiency is something that many homeowners are looking to increase. The roof offers up plenty of opportunities to increase the home's energy efficiency and reduce energy costs. Cool roof coatings, additional insulation, and even full roof replacement can lead to greater energy savings and efficiency over time.
