Roof insulation: how to proceed?

According to building standards, the roof contributes to better insulation of the building. Indeed, the blanket is a real thermal capacitor. And conversely, the roof can have a low isothermal characteristic. About 30% of the internal temperature escapes through the roof. This tends to increase heating bills during the winter seasons.

Thermal insulation then consists of making your house less prone to energy loss. A process that requires the skills of building professionals and especially in the insulation of the roof of a house. Apart from the services of a roofer, isolation occurs in several stages.

Detection of energy loss

This phenomenon is very common in old constructions. Homeowners only realize this when they see their bills go up as the house deteriorates. Indeed, the roof of a house a besoin d’un entretien annuel et d’une rénovation tous les 10 à 20 ans. Une ancienne propriété peut donc présenter des problèmes d’isolement. Ce qui entraîne dans la majeure partie des cas une déperdition énergétique. Cette dernière se manifeste alors par une difficulté de la maison à se réchauffer. Ou encore l’intérieur a du mal à maintenir une température ambiante. Pour certaines constructions, la climatisation doit être poussée à fond avant d’obtenir la température idéale. Ces signes avant-coureurs dénotent une forme de fuite dans l’infrastructure. Le toit est la première partie de la maison que l’on doit inspecter. C’est également le premier élément qui doit bénéficier d’une réparation afin de régler la situation.

External and internal roof insulation

By focusing on the roof, we then proceed to an external insulation. This action commits the expertise of a roofer 34 to repair the frames, add beams and perform all necessary checks. These professionals can also install under-roof screens to prevent the infiltration of air, rainwater, snow, etc. For internal isolation, a waterproofing membrane is installed. It is often used by roofers in homes with low heat condensation. It is also equipped with an anti-insect product (termite, cockroaches, spiders, etc.) which very easily becomes encrusted and pollutes the habitat.

Checking the humidity on the insulation

During insulation work roofs of a house, humidity is a risk that should not be ruled out. A careful study is then pre-established before installing the insulation. The materials used effectively serve to insulate the construction. In this way, neither the heat nor the cold will have any impact on the interior, which allows the dwelling with the attic to be inhabited. However, this condensation of the external temperature tends to seep into the insulation. This leads to increased humidity in the joints of structures and can damage his house very quickly. As a result, checking the tightness of insulation becomes essential.

Each of these aspects requires special attention to the risk of creating subsequent damage to the entire infrastructure of a home.
