Fort Worth Roofing: Article About Energy Efficient Roofs
Where it pertains to construction, sustainability is a relatively recent concept, but it has been gaining a lot of traction in the last couple decades. There are very good reasons why, particularly for those living in urban areas. When a homeowner is considering adding energy efficient improvements to the roof, it is important to discuss available options with a Fort Worth roofing contractor before signing a contract.
One of the problems with most conventional roofing materials is that they conduct large amounts of heat, which is then transferred to the house, raising the cost of cooling the house significantly in hotter weather. Black asphalt shingles, for example, can reach a temperature of 175 degrees on a 100 degree day. Temperatures in Texas and other parts of the southwest frequently exceed this. Metal roofs can also get very hot. One option is to re-roof the home with wood shakes, which conduct very little heat. However, re-roofing is an expensive fix, especially if the original roofing materials are not old.
The less expensive option is to apply a cool coating to the roof that minimizes the conduction of heat. Many stores will have a white cool roof coating that can be painted atop shingle homes. If white is not a desirable color, there are darker, more aesthetically pleasing colors that have reflective properties that will serve to deflect some of the light hitting the roof.

Another effective way to promote energy efficiency is by insulating the roof. There are many different materials to choose from. Their relative effectiveness will depend on the roofing material as well as the local climate, so speaking with an experienced roofing contractor will likely be beneficial. Some of the available insulation materials include fiberglass, cotton batting, foam insulation and cellulose insulation. Cotton batting is highly flammable, so it is best to use with a roof that is not conducive to fire. Radiant barriers can be very effective when used with open beams. Regardless of the insulation used, it is usually recommended to leave an air space between the insulation and the roof.
Those who are looking to re-roof their home completely will have more options. As wood roofs conduct much less heat than other materials, they are effective, but wood roofs do not last very long in wet climates. Metal roofs are relatively expensive, but are more energy efficient than asphalt shingles or tile roofs. Reflective coatings are applicable to all varieties of roofing materials, and elastomeric rooftop coatings can also prolong the lifetime of a roof.
