What is reflective insulation and how does it work?
What Is Reflective Insulation? Reflective insulation, also known as foil insulation, is a material with reflective facing. In most cases, this is aluminum foil or aluminized polyester. This type of insulation reflects heat by up to 95% and prevents it from transferring to the other side of its panel.
What is roof coating and how does it work?
Roof coatings protect the building from water penetration during wet weather, dew, fog, and ponded water situations. The coating is able to repel the water, absorbing none of it into the roof substrate below.
What does reflective roof coating do?
A reflective roof coating system is able to reflect the bulk of the sun's damaging UV rays away from the roofs surface, protecting the roof from premature degradation and aging, while extending the lifespan of the roof.
Are solar reflective shingles worth it?
A reflective roof can help keep a house cooler when the hot sun beats on it, but it will not lower a home's heating bill, and may even slightly raise it. It makes sense to install a cool roof, which reflects heat but does not absorb it, only where the summers are extremely hot or humid.

between 10 and 15 yearsDepending on the particular climate, LO/MIT should last between 10 and 15 years before needing a re-coat. Every building environment is different.
How much more do solar reflective shingles cost?
Solar reflective shingles range between $2 and $3 per square foot, depending on manufacturer and vendor. These typically come in mid-range colors, such as medium browns and grays. They have higher solar reflectance ratings than darker materials, but much lower ratings than a white roof, ranging between 0.25 and 0.30.
What color roof reflects the most heat?
In general, light colors reflect the sun's rays, while dark colors absorb the heat. Therefore, lighter color roofs will deflect more heat away from the home and help to keep the interior cooler. The converse is also true – the darker the roof, the higher the temperatures are likely to be in your roof or upper floors.
Will black shingles make house hotter?
In general, lighter-colored roofs reflect away heat rays from the sun, but dark-colored roofs absorb much of that heat and transfer it into the rooms below. So, yes, black roofs do attract more heat. Or course, color isn't the only aspect of your roof that affects home temperature.

Does painting your roof white help?
Saving money and the environment come into play by painting your roof white. The color white reflects heat, which causes less warmth to be absorbed by the house. Thus, you should have lower energy bills on hotter days.
How long do solar shingles last?
25-30 yearsSolar shingles are quite sturdy, but they are used in place of traditional shingles, so this means that current shingles will need to be torn off and replaced with the solar shingle product. Solar shingles are designed to last 25-30 years, which is a good timeline to keep in mind when you are calculating costs.
Are solar roofs worth it?
Solar panels may be worth it for smaller roofs if you install a system that uses more efficient solar panels, such as monocrystalline solar panels, as they generate more power using less space. The ideal roof slope for solar panels is between 30 degrees and 45 degrees.
Can you walk on solar shingles?
The company noted that its solar shingles install just like regular roof shingles, except for exposing the electrical contacts on the upward side so they can be easily accessed (don't worry — the whole thing is as weatherproof as a regular roof too).

What is reflective roof coating?
Reflective roof coatings are designed to be installed on a horizontal surface, such as a low-sloped roof, tolerating many external stresses and having contact with water for extended periods of time. Reflective roof paint would not possess the ability to be a protectant to your roof or be used as a waterproofing mechanism to your building. Roof coatings protect the building from water penetration during wet weather, dew, fog, and ponded water situations. The coating is able to repel the water, absorbing none of it into the roof substrate below. These coatings are tough enough to be walked on when roof maintenance and equipment on the roof top needs to be serviced. Roof coating systems have a required mil thickness that provides strength and durability, offering adequate protection to the roof’s surface. The thickness also allows for the membrane to expand and contract sufficiently, without cracking or splitting. This flexibility allows the roof to move with the building during different temperature fluctuations.
Is reflective roof paint a paint?
Reflective roof paint is actually not paint. The proper terminology is “reflective roof coating”. While roof coatings resemble paint, they are much more durable and the thickness and strength is unmatched to what paint is capable of.

Reflecting the UV rays away from the roof, ...
Why are roof coatings good for HVAC?
Reflective coatings for roofs also provide energy savings by reflecting the heat from the sun away from the building, allowing little to be absorbed into the building, increasing the efficiency of your HVAC unit because the inside air temperature stays lower. Not only are roof coatings energy efficient but they are also environmentally friendly.

Why do you need reflective roof coating?
For anyone who may not know, a reflective roof coating saves energy in your building by reflective UV rays back into the atmosphere. Most roofing systems absorb UV rays, and that heat is transferred into the building. This means in the summer, you have to run your AC more to heat the building just because the sun is shining.
Why does a reflective roof need to be heated in winter?
A reflective roof doesn’t allow the sun to heat your building. However, due to the angle of the earth, the sun is less intense in the winter.
What percentage of UV rays are reflected off a reflective roof?
So what percentage of UV rays are reflected when you have a reflective roof on your building? Based on several EPA studies, roughly 88% of UV rays are reflected off a white silicone roof. Compare that with a 17% average for non-reflective roofs, and that’s a huge improvement. That can be the difference of about 60 degrees in roof temperature. Depending on your insulation in your building, that can be between 20 and 30 degree difference below the roof. What a difference!
