It’s no secret that heat absorbed by a roof on a hot summer day raises the temperature in the house, contributing to a range of expensive methods in trying to regulate the air. For this reason, it’s important to know that you can learn how to cool your roof in several tips.
On a regular and hot sunny day, the temperature on the surface of a traditionally dark or black roof can rise to more than 50 degrees Fahrenheit warmer than the surrounding temperature.
If you live in the city, just imagining sweltering rooftops next to each other creates an elevated block of dark material that absorbs heat and creates waves of high temperatures.
And even in suburban areas, there’s no escape from the summer heat when it starts beating down. This leads to higher energy costs and air conditioning requirements. All in a bid to stay comfortable.
Fortunately, there is a remedy to how much heat your roof is absorbing. And it comes at low-costs and less technology.
5 Tips on How to Cool Your Roof
Your roof either absorbs heat or reflects it. And the roofing factors you need to consider the next time you have a roofing project include:
- The color of your roof: Dark colors for roofs tend to absorb more heat, while light-colored roofs do the opposite.
- Roof pitch: Flat roofing systems, or low sloped roofs take in more head. They receive heat from the sun more directly.
- Absence or presence of insulation: Your roof’s insulation acts as a barrier that prevents energy from leaking through your roof.
#1 Get roof ventilation installed
Metal roofing systems for residential and commercial buildings will take huge investments. However, you will need proper ventilation if you want to lengthen your roof’s lifespan. Here are some of the ways roofing vents can preserve your roof and keep it cool at the same time:
- Vents maintain air quality you and your family breath. Poor air quality affects people’s health and productivity.
- Vents let warm air escape. So you don’t have to worry so much about metal contracting and expanding.
- Vents also control condensation. This preserves and maintains the performance of insulation. And during the summer, you’re actually giving warm air inside an escape. They leave through the vents and get rid of humidity in the process.
#2 Spray forms for roofing insulation
These are usually referred to as SPF (spray polyurethane foam insulation). It’s a chemical product that cools the rest of the indoors. Having it in addition to your current roofing system will give your roof an additional barrier. It prevents air leaks and fluctuating room temperatures.
In addition, knowing how to cool your roof also means understanding the other benefits of using SPF. Aside from cooling they also:
- Reduce damage to the structure.
- Protects your home from pests.
- Increases your home’s resistance to wind uplifts.
#3 Applying reflective roof coatings
Reflective roof coatings are what are applied to rubber and metal roofs to significantly reduce heat from the rooftop. They work in one out of two ways.
First, reflective roof coatings have thermal emittance. This means that heat absorbed by the roof is reflected back instead of being allowed to penetrate the building. And second, the coating repels sunlight the moment it hits the surface of the roof.
In addition, a reflective roof coating also improves energy-efficiency. This is another great way or reducing workload for your in-house cooling system along with other utility bills.
#4 Opting for green roofs
If you have the finances for it, opting for green roofs (or living roofs) are very wise. In addition to the obvious health benefits of having greenery in and out of the house, green roofs absorb heat. Furthermore, you also contribute to decreasing the production of air pollution and greenhouse gas emissions.
As expected, the obvious obstacle to this being a common practice, is that green roofs actually cost two or three times more than our traditional roofs.
However, despite the money needed to make it a reality, many cities and people can easily see the long-term benefits. And that fact alone is enough to convince some people that green roofs have more pros than cons.
#5 Think about investing in professional roofing services
Do you know how old your roof is? What about its current condition? Are you sure about your family’s safety with your current roof’s health?
These types of questions need to be asked when you’re thinking about a roofing project, and when you’re considering on making your roof more reflective to heat. So, while you’re in that train of thought, it’s time to consider investing in professional roofing services.
It’s important that you have professional roofers come to your home once in a while to check and see how well your roof is faring against the elements.
Regular inspections and excellent roof upkeep is the secret to a healthy lifestyle. In addition, knowing exactly how to cool your roof helps plenty in ensuring that you’re living in the best conditions during the trying summer months.
