Does your house have a roof that reflects heat? If yes, then you’re probably wondering whether or not you should invest in heat-reflective paint on the residence roof.
Heat-reflective paint has become very popular because it helps homeowners save energy costs. This type of paint allows sunlight to pass through the surface without heating up the home’s interior.
It’s important to note that these paints aren’t always effective at reducing solar radiation gain. Some roofs don’t reflect enough heat, and some areas of the roof absorb too much heat. In addition, this paint isn’t suitable for every roof design.
If you want to know if heat-reflective paint is right for your roof, keep reading. We’ll explain why this type of paint can be useful, as well as what you need to consider before buying it.
Why Should You Invest In Heat Reflective Paint?
When you think about how much money you spend on electricity each month, you may wonder why you would ever want to paint reduces your energy bills. However, there are many reasons why you might want to do so.
For example, you could use less energy by installing air conditioning during the summer months. Or, you could install a programmable thermostat to help you conserve energy when you’re away from home.
In addition, you could also use less energy by investing in heat-reflective paint.
This type of paint lets sunlight pass through the surface without warming up the home’s interior, which means you won’t have to pay as much for heating and cooling roof.
You can find heat-reflective paint at most hardware stores. It comes in various coloured paint, including white, grey, black, blue, green, red, yellow, orange, and brown.
How Much Does Heat-Reflective Paint Cost?
The cost of heat-reflective paint depends on several factors, such as:
- The size of your roof.
- How long it will last? What colour will be most effective at reflecting heat?
- What colour did you choose?
- Whether you need to repaint the roof.
What Are The Benefits Of Using Heat-Reflective Paints?
There are several benefits associated with using heat-reflective paint on your roof. Here are just a few:
- It keeps your house or building cool.
- It saves you money.
- It makes your roof look better.
- It increases the value of your property.
- It protects your roof from weathering.
- It helps prevent algae growth.
- It prevents water leaks.
- It helps keep the area around your house protected from insects.
These are just a handful of benefits. But they’re all good reasons to invest in heat-reflecting paint.
However, you shouldn’t expect to see any significant energy savings from this type of paint after one year. After that time period, the amount of energy efficiency you save begins to decline.
Also, remember that heat-reflective paint doesn’t work for every roof design. For instance, it won’t work properly if your roof is covered with shingles or tiles.
What colour will be most effective at reflecting heat?
Heat-reflective painting comes in different shades. When choosing a colour, make sure it reflects light effectively.
White is often the best choice for homes located in sunny climates. White is known to reflect more than 90% of visible light.
So, if you live in a warm climate, you should select a lighter shade of white. If you live in a colder climate, you’ll probably want to go with a darker shade of white.
Keep in mind that even though dark-coloured roof shades reflect more heat than lighter ones, they don’t always provide the best insulation against solar heat gain.
So, if you plan to place heat-reflective paint directly over asphalt shingles, you should avoid using dark colours. This is because dark colours absorb more heat than they reflect.
If you’re going to use heat-reflective coating over tile roofs, however, you can safely use dark colours. This is due to the fact that tile roofs tend to stay cooler than other types of roofs.
When selecting a colour, think about how much natural light your home receives. Also, consider whether your roof has a lot of trees nearby.
A tree canopy tends to block out some of the sun’s rays. So, if your roof faces south, you might not benefit from using a dark colour.
In addition, if you live in an arid region, you may want to opt for a lighter colour. In these areas, heat tends to build up quickly.
As a result, a roof painted in a dark shade could actually cause your house to get hotter.
Does heat-reflective paint work on metal roofs?
Yes, heat-reflective paint works well on metal roofs. However, there are some things you need to know before applying it.
First, metal roofs tend to be warmer than other types of roofs during the summer months. So, when you apply heat-reflective paint to a metal roof, you may find that it only provides limited relief.
Second, metal roofs aren’t as susceptible to rain damage as other types of roofs. As a result, heat-reflective paints tend to peel off easily.
Third, unlike other types of roofs, metal roofs aren’t usually insulated. So, if you apply heat-reflecting paint to a metal roof and then cover it with tar paper, you may end up trapping heat inside your home.
This isn’t necessarily a problem. But, if you do choose to insulate your metal roof, make sure you seal all cracks in order to prevent moisture from penetrating into the attic.
How long does heat-reflective paint last?
The lifespan of heat-reflective paint depends on several factors. These include:
- The quality of the paint itself.
- How exposed your roof is to sunlight.
- Whether or not you have a shady area near your roof.
- The amount of time your roof spends being heated by the sun.
Generally speaking, heat-reflective roof paint lasts depending on the type of material used. For example, if you use high-quality paint, you can expect it to last at least 5 years.
However, if you use low-quality paint, you may only be able to rely on it for 2 years.
Also, if you live in hot weather, you may find that you need to reapply heat-reflective roof paint every year.
What is the difference between heat-reflective paint and solar-reflective paint?
Solar reflective paint is basically a form of heat-reflective roof coating. It’s made from special materials that allow them to both reflect and absorb the sun’s energy.
This paint comes in different forms. Some people prefer to paint their rooftops black. Others like to use white. And still, others like to use metallic shades.
Heat-reflective paint doesn’t require any maintenance. In contrast, solar reflective paint needs to be cleaned regularly. This is because dirt absorbs heat.
So, if you plan to install solar reflective paint, you’ll need to clean it regularly. Otherwise, the heat-absorbing properties will decrease over time.
Which one should I go for?
When deciding which type of paint to use, consider the following:
- Your budget.
- Your roof shape.
- What kind of colours you’re looking to achieve.
If money is no object, you might want to invest in solar reflective paint. This is because its ability to reflect and absorb heat makes it more effective than heat-reflective paint.
However, if your budget is tight, you may want to opt for heat-reflective roof coatings instead. They provide better protection against the sun’s rays.
