The Advantages and Controversy of White Commercial Roofing Materials

Much has been documented in recent years about the advantages of installing white or “cool” roofs. The concept is that light-coloured surfaces reflect heat, while dark roofs, such as those made of asphalt and tar, retain heat, increasing air-conditioning demand to compensate.

Installing a white or “reflective” roof, in other words, helps conserve energy and resources.

But is the hype about cool roofs legitimate? Are you considering one for your business?

Although white roofs can reduce electric bills during the hot summer months, studies show that they raise winter heating bills. The question is, by how much? According to some scientists, white roofs will raise heating costs more than they save on A/C costs. However, according to scientists at Lawrence Berkeley National Laboratory, the energy benefits of air conditioning outweigh all drawbacks, even in cold cities.

Another concern is whether reflective roofs can cut their net value – and whether they potentially slow global warming. According to a Stanford report published last year, the heat represented by white roofs may intensify climate change by adding more heat to the atmosphere and absorbing more pollutants. On the other hand, previous research has indicated that whitewashing roofs may have a cooling effect.

If you plan to put a white roof on your company or house, do some homework on the prices and alternatives in your area and get at least a few bids from various contractors. Reflective roofing materials come in a variety of styles.

White Roofs Keep Your Commercial Building Cool

Do you commercial building situated anywhere where the summers are hot? A white roof will significantly differ in your commercial building‘s temperature, energy savings, and roof lifespan.

Consider this: in the summer, we choose to wear light-coloured clothes rather than dark ones because they represent heat and keep us cool. White roofs have a similar impact, and they support both us and the world.

There are some options to add a white roof to your commercial building:

  • Paint a current dark roof with a translucent white coating with a solar reflectance index (SRI) of up to 90%.
  • Solar reflective asphalt shingles or clay
  • Concrete or fibre cement tiles
  • A white roof also emits thermal radiation, which is a significant feature. A white roof can emit up to 90% of absorbed heat, keeping your home at a consistent, cooler temperature. This improves energy efficiency, lowers maintenance costs, and raises the lifespan of the roof.

The “Heat Island Effect”

Since we’ve replaced plants with asphalt, urban areas are always hot. Not just that, but they are often covered with other dark surfaces such as roofs and a large number of humans. All of the dark surfaces absorb a lot of heat and do not reflect nearly enough of it.

The so-called urban heat island phenomenon leads to climate change by requiring residents to use a lot of electricity to cool their homes. White roofs tend to alleviate this problem by absorbing considerably less sunlight and lowering overall region temperatures. Cooler temperatures also mean less smog!

White Commercial Roofs Can Save You Money

Since white roofs consume far less heat, the interior of your home will remain cooler, eliminating the need for air conditioning. If you live in a hot environment, you can even use UV-blocking window inserts to keep your commercial building cool. They prevent solar heat gain through your windows. Both tactics reduce your energy intake, lower your carbon emissions, and save you money.

White roofs usually last twice as long as black roofs because they do not absorb heat, which can cause cracking and warping. They come with more extended warranties, which necessitate less upkeep and repairs. They minimize waste going to landfills, and they don’t have to be replaced as much.

A white commercial roof is an excellent renovation for professional repairs. However, whether you have never worked on your commercial roof before or the thought makes you anxious, consider hiring experienced roofing contractors.

Roofing Materials To Keep Your Commercial Building Cool

Because of the colder season, now is an excellent time to consider your roof: is it energy efficient? How would you improve the efficiency until next summer to keep electricity prices as low as possible?

Sometimes a simple roof cleaning is needed to restore the roof’s appearance and increase its lifetime. However, substitution is also inevitable. Energy quality is a significant consideration when it comes to replacing a roof! This article will look at ten roofing materials that will help keep your home cool while also improving energy quality.

Terra Cotta Tiles

Terra-Cotta tile is a curved pattern made of baked clay. It is highly weather-resistant and long-lasting – this style of roof usually lasts 50 years. The curvature of the tiles also increases air conditioning, which helps to minimize the amount of heat that enters the home. However, one disadvantage of terra-cotta is that it is heavier and more costly than other roofs.

Concrete Tiles

Concrete tiles have the same heat-reduction properties as terra-cotta tiles, but they are much less costly. In addition, concrete tiles’ thickness ensures they take longer to heat up in the light, keeping your house cool. They can also shape them in the same curved shape as terra-cotta tiles, which increases airflow, and some tests have shown that curved concrete tiles can reflect up to 74% of heat. This roof style can be dyed to make it more aesthetically appealing, but it is very thick.

EPDM Roofing Membrane

This substance is a mouthful, and it is also known as rubber roofing. However, it is not rubber; instead, it is a plastic rubber-like substance that is highly weather-resistant. Can cut it into a range of shingle shapes and sizes to fit various home designs. As titanium dioxide is applied to it, it absorbs a lot of light and effectively removes heat on the interior of a home.

Metal Roofs 

Metal roofs were once thought to be inexpensive and unattractive, but they have lately become trendy and valuable as an affordable, energy-saving alternative for homeowners. They are eco-friendly because they are often made from recycled metal, and they minimize heat absorption because they reflect a lot of light. However, the dead space region between the metal roof and the house’s interior is the key to their energy efficiency—this air buffer aids in reducing heat flow from the roof to the building. In addition, metal roofs often cool faster at night, allowing less heat to be absorbed and transferred to your house.

Green Roofs

Green roofs are just as they sound like: a waterproof sheet of material covered with trees. Green roofs are excellent energy savers in any environment, as they reduce heat flow during the summer and trap heat during the colder months. Of course, they’re perfect for the atmosphere. They do more than just mirror sunlight; they capture and use it without moving it to your house. With the growing success of green roofs, you have many choices for the visual design of your roof, so you don’t have to go funky to go green!

Asphalt Shingles

Asphalt shingles are very popular, but they are a good choice for energy-efficient roofs. They are designed to reflect both UV and infrared radiation, reducing heat transfer to your house. Plus, they don’t have to be the hideous version of asphalt that we all imagine – they can be any colour to fit your style!

Slate Tiles

This type of roofing is a more upscale choice than concrete or terra-cotta roofs. Stone tiles, and other forms of roofing, are opaque and minimize heat flow, and their thickness slows heat absorption. However, they are both attractive and long-lasting, resistant to weathering, and less upkeep than other forms of roofing. The main disadvantages of slate tiles are that they are thick and more costly than many other roofing materials.

Solar Panels

Solar panels are perhaps the best of all worlds for roofs. Solar panels are an appealing choice for building owners because they are aesthetically pleasing, energy-efficient, and almost as economical as other styles of roofs. Rather than merely reflecting heat, they absorb it and convert the sun’s energy into electricity. In essence, solar panel roofs save you money in two ways: they limit heat flow to your house, requiring your air conditioner to work less complicated, and they use the sun’s resources, requiring you to purchase less electricity from the power provider. Best of all, as they become more popular, the cost of installation is decreasing, and they come in a range of shapes and sizes, so they look nice on your roof as well.
