Did you know your roof plays an integral role in indoor temperature maintenance? Or that the materials your roof is made out of can either improve or decrease your household energy efficiency? At Keyprime Roofing, we know how important the right roofing materials are for both performance and longevity. To help you make an informed decision, we’ve outlined which roofing options are your best bet for combating summer heat while keeping your monthly energy bills reasonable.
What Is a Cool Roof? Do You Need One?
Ever heard of a cool roof? No, not like the cool roof on the block — “cool” in this case refers to heat absorption, or lack thereof. According to the U.S. Department of Energy, cool roofs are specifically designed to absorb less heat from the sun than standard roofs.
It’s a lot like wearing a white t-shirt instead of a black t-shirt on a hot, sunny summer day — the white t-shirt reflects sunlight, keeping you cool, while the black t-shirt absorbs the sun’s rays, raising your body temperature. A cool roof functions much the same way: it reflects more sunlight, which helps to maintain a more comfortable temperature inside your home.
So which roofs are “cooler” than the others? Well, that depends on a variety of factors. Certain roofing materials are manufactured to deliver better insulation, but specialty coatings also exist that can make less “cool” roofing materials more reflective and insulating. Below, we’ve listed the materials that are manufacturer-designed to deliver superior heat reflection and insulation against the summer sun.
Naturally more reflective than other roofing materials, metal roofs can help increase household energy efficiency because they provide excellent insulation against the sun’s heat. In fact, with a metal roof, it’s possible to save up to 40% on your annual heating and cooling costs. Keep in mind, however, that energy cost savings with metal roofing depend largely on the type of finish the metal features.
A basic, unpainted metal roof provides greater solar protection than asphalt shingles; however, high-emissivity paints and granular coating can be applied to further increase the material’s reflective properties. Beyond energy efficiency, metal roofs also offer incredible durability due to their impermeable and rot-resistant nature. Other benefits of metal roofing include:
● Longevity. On average, a metal roof lasts anywhere from 50-80 years, depending on the integrity of the installation and quality of the material.
● Wind resistance. Metal roofs are rated to withstand winds of up to 140 miles per hour, which is essential in our tornado-prone Twin Cities climate.
● Fire resistance. Metal roofing is completely fire retardant.
● Minimal maintenance. Metal roofs require little to no maintenance, despite their impressively long lifespan.
In terms of aesthetics, metal roofing can be painted in a variety of colors and finishes, making it fully customizable and complementary to virtually any architectural design. While it’s not the most affordable roofing option on the market, its impressive list of benefits more than justifies the additional cost.
Perhaps the most popular roofing material in the Twin Cities area, asphalt shingles offer a lot in terms of design flexibility. However, they don’t offer the level of heat emissivity that metal boasts. According to cool roof research specialists, asphalt shingles’ peak heating is approximately 25% better than a completely heat-absorbant roof, which isn’t great in terms of energy efficiency.
That said, certain types of asphalt shingles feature higher-emissivity granular coatings, which are specifically designed to reflect a greater percentage of the sun’s rays. Opting for shingles that feature granular coatings with white or reflective particles can still help improve indoor temperature regulation, but not to the degree that a metal roof will.
Though asphalt shingles may not be the best option in terms of heat insulation, they do offer several benefits, including:
● High cost-to-value ratio. Of all roofing materials, asphalt shingles are the most affordable option.
● Design versatility. Asphalt shingles are available in a wide range of styles, colors, shapes, and finishes.
● Fire resistance. Asphalt shingles boast a Class-A fire rating.
● Ease of installation. A roof installation with asphalt shingles requires minimal time to complete. Unlike other roofing materials, most asphalt roofs can be installed in only a day or two, depending on weather conditions and the condition and design of your roof.
Slate or Tile Roofing
Last but definitely not least, slate and tile roofing offer incredible protection against the sun’s rays. Because both slate and tile are quite dense, they absorb little heat from the sun, which is the reason behind their popularity in perpetually warm Southern climates. Both slate and tile can also be coated in specialty glazings to increase their reflective properties, which will further enhance insulation against heat. According to the Tile Roofing Industry Alliance, research indicates that slate and tile roofing can reduce ceiling heat flux by up to 40%, which translates to significantly lowered annual energy costs.
