How to Beat the Heat With Energy-Efficient Roofing

August 25, 2022

energy-efficient roofing in Dallas Texas

Conventional roofs can be scorching on a summer’s afternoon. Research shows that they may get 55 to 85°F hotter than the air and reach temperatures of 165 to 185°F.

On the other hand, cool roofs only reach 10-20°F above the surrounding air temperature. Implementing cool roofing solutions will lower the surface temperature and reduce the average daily AC electricity use anywhere from 2-63%.

Read on to find out how you can save electricity and money while staying cool in the heat!

What Is Considered Energy-Efficient?

An energy-efficient roof reflects sunlight and heat, leading to lower temperatures inside the building it covers. Hence, less need for air-conditioning and reduced energy consumption.

Roofing materials can reflect sunlight at varying levels, so their energy efficiency is measured using the Solar Reflectance Index (SRI). Each material has an SRI rating (between 0-100) – those with a higher rating are better at reflecting heat.

Roof Color Plays a Factor – But It’s Not the Only One!

Lighter roofs do reflect more sunlight than darker ones. However, the material used has a greater impact on energy than the color choice.

You can easily find excellent options in a variety of hues. In fact, bright white options aren’t typically marketed for steep-sloped roofs precisely because of aesthetics.

Cool Roof Materials

It’s best to pick based on material and consider style later on. Here are the most common options. 

  1. Tile Roofs

Tiles can be made from slate, concrete, or clay, and they’re very durable. The materials effectively release heat and may even be pre-treated to maximize their reflecting capacity.

The main advantage of tile roofs is the structure. The tiles are overlapped, creating channels that allow for increased airflow, leading to increased energy efficiency.

  1. Metal Roofs

Metal roofs can be installed as a series of panels or as classic roof shingles. They’re usually made from steel or aluminum. 

Metal roofs are an appealing choice as they’re highly reflective and have a lifespan of over 50 years. Metal is also among the most sustainable roofing options, as it can be fully recycled.

  1. Asphalt Shingles

Asphalt shingles are a low-price and easy-to-install option. Although they are poor at reflecting heat, they are worth considering as a more affordable solution.

Energy-efficient asphalt shingles are made with special reflective granules with a higher SRI that will promote sun reflection.

  1. Solar Shingles

Solar shingles are not only designed to offer protection from the sun but also generate energy in the process. They contain photovoltaic cells, which are also used in standard solar panels, and convert sunlight to electricity.

The initial cost of solar shingles is high, but they have a high ROI, and you might be able to offset costs with renewable energy incentives.

  1. Green Roof

You may want to look into green roofs if you have a flat roof. This type is essentially a layer of vegetation placed on top of your building.

Green roofs are sustainable, energy-efficient, and can improve air quality but require more routine maintenance than other types.

Cool Roof Coatings

Getting cool roof coatings is a less expensive solution than purchasing a new roof. These are thick layers resembling paint that are applied to certain types of roofs. Cool roof coatings increase reflectivity while also protecting your roof from UV damage.
