What is the best roofing material for energy efficiency?

If energy efficiency is the primary goal of your new roof, the roofing types you’ll want to consider are metal roofing and asphalt shingles. They are the most energy-efficient roof materials and will best reflect the sun’s rays from your house.

Metal roofing

Metal roofing, while expensive, gives the best return on your investment in terms of energy efficiency. Metal roofs effectively reflect heat away from businesses and homes and can save up to 40% on energy costs. 

Metal roofing has a variety of finishes that make your roof more energy-efficient. Pre-painted and granular coated metal roofs can readmit up to 90% of the heat that hits them. 

These highly reflective coatings use cool pigments in the paint to keep the roof temperature low and reflect the maximum amount of heat that hits the roof. This reduces the need for air conditioning and keeps your home or business cool and comfortable. 

Asphalt Shingles

Another energy-efficient roofing material is asphalt shingles. Asphalt shingles are the most cost-effective roofing type when it comes to energy efficiency and cost around $3.50 to $6.00 per square foot. Asphalt shingles are also the easiest roofing type to install and the most cost-effective to repair.

It is important to note that the asphalt shingles must be infused with reflective granules. Similar to metal roofing when asphalt shingles are infused with reflective granules the shingles are a cool roofing material and will direct the sun’s rays away from your home and keep the interior cool. Asphalt shingles are not as effective as metal roofing as reflecting heat but they are more affordable and are an excellent option for any home.

What is the Best Color Roof for Energy Efficiency?

You may be on the hunt for the most energy-efficient roofing material and color, however, there is not a single color that will perform better than another. However, light colors absorb fewer UV rays and will typically outperform a dark color which will retain heat. Opting for cool roofing materials and cool roof paint will also serve you best in reflecting heat from your home. 

In particular, asphalt shingles that are brown and black don’t have Energy-Star ratings due to all the heat and UV rays absorbed and the amount of heat retained. Opting for lighter colors paired with cool roof paint will be the most effective in keeping the interior of your home cool. So when you are thinking of colors for your new roof, the lighter the better!
