How Your Roof Affects the Temperature of Your Home


As we get closer to winter, the coldest part of the year, many homeowners are wondering how they can keep their homes as warm and as comfortable as possible.

One of the things that often doesn’t cross their minds is the roof. However, the roof plays a significant role in maintaining optimal indoor temperatures. There are several different aspects and factors of a roof that directly influence the amount of hot or cold air that will end up inside your home. Let’s have a look at some of the most important ones.

Keep Warm with the Right Roofing Material

Roofing material is one of the key factors that will affect your home’s indoor temperatures.There are certain roofs that will, for example, reflect the heat as well as those that will absorb it and help keep your home warmer. 

Asphalt shingle, for example, is a type of roofing material that does not reflect a lot of heat or light. It is estimated that asphalt shingles reflect about 30% of the light that hits your home, which can prove to be beneficial during cold winters. With asphalt shingles, your roof, attic, and home will be able to absorb more heat from the sun and therefore, stay warmer and more comfortable.

If you, however, want a nice and cool home during the hot summers, then you can opt for one of the many cool roof options, such as metal roofing. Metal roofs are known to reflect most of the light and the heat that comes from the sun, helping your home stay cool and more energy efficient. In addition to that, metal roofing is also known to provide great comfort throughout the year by maintaining even temperatures year-round.

There is an array of other roofing materials, all with different absorption properties, so it may be hard to choose the best one for your needs. It is also important to mention that these properties of a roof do not change as the seasons change. This means that if your roof reflects the heat off during summer, it will also reflect it off during winter. Therefore, you should carefully consider which roof you are choosing, i.e. which season of the year is harsher and affects you the most. Your roofer, however, can provide you with expert advice as well as a series of options that will suit your exact needs.

Choose the Right Roof Color

The color of your roof will not only affect your curb appeal and enhance your architectural style. It will also have a significant effect on your home’s inside temperatures. Therefore, when considering different roofing options, make sure to choose the material and color that best fit all of your needs, including the levels of comfort inside your home.

When it comes to the color of your roof, the main principle is pretty straightforward – darker colored roofs will absorb more heat and keep you home temperatures higher. Lighter colored roofs, on the other hand, will help to decrease the temperatures and keep your home cooler. This happens because lighter colors are more reflective than the darker ones and will, therefore, reflect both the light and the heat off of your roof.

Darker roofs, on the other hand, tend to hold onto the heat that comes from the sun more so than the lighter ones, heating up the beams beneath it, the attic, and the rest of your home. Darker colors on roofs also work great in areas where there is a lot of snow as the snow will melt more easily off of them. 

So, which color to choose? It will all depend on the weather that you get and the goal that you want to achieve with your roof. Your local roofer will undoubtedly be able to help you with this, advising you on the color that will work best year-round.

Add Attic Ventilation and Insulation for Increased Comfort

The ventilation and insulation that you (don’t) have under your roof will affect your indoor air temperatures greatly. Apart from keeping the roof’s structure in great shape and preventing its malfunction, the attic ventilation has an important role in maintaining optimal indoor temperatures, as well.

The ventilation will allow the air to circulate in a natural and healthy way, preventing both the buildup of hot or cold air in the attic, as well as too much of it escaping outside. In other words, it will maintain an optimal exchange of hot and cold air, keeping your indoor environment healthy and comfortable.

When it comes to attic insulation, it has a very similar purpose – to maintain optimal temperatures inside your home. It helps to keep you warm during winter and cool during the summer. With the right amount of attic insulation, for example, you can also help prevent the cold or the heat that comes from your roof from reaching the rest of your home. 

This means that if you have a darker colored roof that absorbs heat, the insulation will be very helpful in the summer as it will prevent that heat from reaching the rest of your home. Therefore, if you don’t have a ventilation system or insulation in your attic, or you think they are not working properly, it is a good idea to have a professional assess your home and add or update them.


Keeping your home nice and comfortable is not always an easy task, especially if you don’t know how different parts of your home affect your indoor temperatures. The roof is one of the most important parts of your home and as you have seen, it also has a major role in keeping it warm or cool enough.

Roofing materials, colors and other aspects such as ventilation and insulation can help you maintain optimal home temperature and ideal comfort levels. Therefore, if you’re looking for a new roof or your current one is up for a replacement, it is a good idea to consider this aspect as well.
