Non-reflective rooftops are the most popular in the summer heat. Even with good insulation, heat can penetrate roofs and warm attics and top floors, and air conditioners are forced to work extra hard to keep up. This costly problem can be avoided by replacing or treating the roof with cool, reflective roofing materials.
Although replacing an existing roof can be costly, a cool roof could pay for itself in the long term. This is especially true for homes where the roof is not energy efficient. You don’t have to worry about how much it will cost if your budget is not available for such a large job. Energy-efficient roof coatings in Fuquay Varina and Apex or Holly Springs NC may allow you to achieve similar results at a fraction of the cost.
Energy Star Roofing
The federal Energy Star program offers homeowners assistance in selecting energy-efficient roofing materials. The same ENERGY STAR labels that you see on appliances are also applicable to shingles, roofing panels, and energy-efficient roof coatings. Roof materials awarded the ENERGY STAR label show a high level of solar reflectance. They reflect more heat from the sun than other materials, which is why they have earned the ENERGY STAR label. These materials can reduce the roof’s surface temperature by 50 F. This can lower peak air conditioner demand by as much as 15%
Roof Color and Energy Efficiency
It might seem obvious that a lighter roof is better than a darker one, but the reality is not as simple. Although lighter colors are more reflective of heat, roofing materials can significantly impact roof energy efficiency. A roof with a higher ENERGY-STAR rating will typically outperform a lower rating.
Also, consider your climate. In the hottest temperatures, lighter roofs are a better choice, and a darker roof can absorb heat from the sun in winter and is better suited for homes in cooler climates. You’ll find many colors in any roofing material. It is best to choose your material first and then your color.
Which Roofing Material Is Most Energy-Efficient?
Asphalt shingles are the most popular roofing material because of their affordability and ease of use. Asphalt shingles can absorb heat well and reflect it poorly, even when lighter in color.
Metal is used in many energy-saving roofing systems that are eligible for the ENERGY STAR label. Metal is reflective even though it can get very hot in the sunlight, and the heat is directed away from home below, where it makes up most of the heat. Metal roofs are available in various styles, including shingles with a more traditional look or a series. They are also straightforward to install.
A tile roof is another option for efficient roofing. You can make tiles from clay, concrete, or slate. The latter is the most durable. Pre-treatment is a standard method of increasing heat reflectivity in tile roofing materials, and these roofs can be easily treated with reflective coatings once installed.
What about non-single options?
You can apply coatings to many roofing materials, which are not compatible with asphalt roofs. The color and physical appearance of most roof coatings can also be affected. Therefore, the most reflective coatings might not match your home’s exterior colors. However, there are pigmented coatings! Although they are less efficient than white coatings, they can still increase the roof’s reflectivity.
If you have flat roofing, you might consider installing a green roof. A green roof is not a roof painted green; and it’s a roof with a garden on the rooftop. It can be a costly and challenging task to design and install one. It’s also energy-efficient and creates a fun environment in an otherwise unused space. You can even use it to feed your family!
Insulate to Increase Energy Efficiency
Although an energy-efficient roof can make a big difference, it cannot do everything. You may still have problems if the insulation isn’t up to par. Attic fans and roof rafters can help increase air circulation, which will reduce temperatures under your roof. If you consider energy efficiency upgrades to your roof, it is worth upgrading your attic. Do not let your dark asphalt roof trap heat inside your home. Think about your roof now and consider energy-efficient roofing materials.
