Is Your Roof Energy-Efficient?

One of the biggest influences over your home’s energy efficiency is the roof.  An energy-efficient roof not only protects your house from the elements but also keeps air-conditioned or heated air contained within your home, reducing energy costs.  With energy costs constantly rising, it’s becoming more important than ever for homeowners to make their home more energy efficient.  A little effort can go a long way and your entire home will benefit from it.  Below we will discuss the qualities of an energy-efficient roof and the changes you can make to increase your home’s efficiency.


An energy efficient roof should be well insulated from the rest of your home.  Attic insulation plays a huge role in the overall health of your roof and the energy-efficiency of your entire home.  Foam or insulation that is blown in are the two popular choices because they are easy to install and very effective.  

It’s important to assess your existing attic insulation to make sure you have no missing or improperly insulated areas. These defective spots can be a source of air leaks where heat can get into your home in the summer or escape in the winter.  These air leaks can contribute to poor roof health.


A well-ventilated roof is a healthy roof.  Ventilation is critical for your home’s energy efficiency.  Without the proper ventilation your attic will overheat making it nearly impossible to effectively cool your home.  

A well-ventilated attic may get warm, but it never gets much warmer than the temperature outside. Here’s how a well-ventilated attic works.  The warm air escapes your attic through a vent on your roof and is replaced with cooler air from intake vents down low.  As a result, your attic stays cooler and your home remains energy efficient.


A dark roof absorbs more heat from the sun than light-colored roofs, and as a result, more heat is transferred to the underside of the roof deck and to the attic below. To remedy this problem, there are energy-efficient shingles in solar-reflecting colors that can help reduce the heat transfer.  But we want you to keep in mind that an energy-efficient roof isn’t simply a matter of shingle choice.  Any shingle will work best in combination with these other energy-saving items we have covered above.


Many of the energy saving roofing systems that qualify for the Energy Star label are made from metal. Even though metal gets very hot in the sun, it is highly reflective so that most of the heat is redirected away from the home.  Another good choice for energy efficiency is tile.  They can be made from slate, clay or concrete.  Many tile roofing is pre-treated to maximize heat reflectivity.

A well-constructed roof made of high-quality materials is energy efficient, cost effective and environmentally responsible.  If you think you may need a new roof, contact Williams Roofing Company at 831-758-2749 or visit us online to request an estimate.  We build trust and peace of mind into every Williams Roof.
