Cool flat roof: a useful solution during the summer
Summer often means heat! That’s why it can be difficult to keep your home cool during the summer season, especially when it has a flat roof protected by asphalt or asphalt. To save you from spending large amounts of money on ventilation to counter the heat, here are a few tips you can follow to get a more comfortable living space in the summer.
Use light-coloured membranes on your flat roof
In order to keep your home cool, you need to put in place what is called a “cool roof”. It is a roof that is able to reflect some of the sun’s rays instead of absorbing them and retaining heat. To obtain this type of roof, you can install a white bitumen elastomeric membrane at the top of your house. This membrane reflects a large part of the sun’s rays and reduces the effect of heat islands in urban areas. It can usually extend the life of your roof by up to 30 years.
If you’re looking for a slightly more aesthetic result on your flat roof, opt for a light grey membrane instead. It offers much the same advantages as the white one but costs a little less. Such a material may be less effective if you live in a wooded area. Indeed, it can sometimes be worn away prematurely by the sand moved by the wind. You will therefore need to maintain it regularly so that it remains durable.
Add gravel to your roof
If your flat roof is made of an asphalt membrane, you may want to replace it with a built-up roof. Among other things, it has a layer of asphalt covered with gravel. This method is very practical in summer because the small pebbles are able to reflect some of the sun’s rays. They therefore ensure that the asphalt layer does not contract during temperature changes. This keeps it strong and waterproof for longer. Thanks to this winning combination, it is possible to obtain a surface that can last from 20 to 25 years. This always depends on the quality of the materials used.
In addition to its beneficial effects against heat, gravel can also be used as ballast to hold the different layers of the roof in place. This prevents them from being blown away by the wind, as they are not always sealed on top of each other. The advantage of this type of roof is the much easier and faster installation. However, you will need to maintain the rubble and ensure that it is present in sufficient quantities on the roof. This ensures that it is not damaged.
Opt for a synthetic coating for a cool flat roof
Synthetic coverings, such as PVC or TPO (thermoplastic polyvinyl) roofs, are mainly found on industrial or large-scale buildings. However, they can also be found on the roofs of some homes in Quebec.Very light and easy to install, they are often spread in a single layer. In addition, they are attached to the roof using glue or a welding machine. Some of them are even available in white to keep your home cool during the summer.
Synthetic pavement is usually less expensive than asphalt and gravel pavements.
It is also low-maintenance.
However, the harshness of the Quebec climate risks making the glue that holds it in place ineffective.
You will need to inspect your roof every spring.
So make sure it stays in good condition and make repairs if necessary.
Generally, such a coating lasts 15 to 17 years in Quebec, depending on the quality of the material it is made of.
