What roof for my porch?

Installux "Realization side Berries"

Aesthetics, luminosity, thermal and sound comfort: the roof is an essential element of a veranda. How to choose? Flat or slanted, glazed or opaque ... our answers.

The roof gives style to the veranda and, more generally, to the whole house: flat and opaque for a contemporary look, faceted and glazed for a more traditional look. But it's not just aesthetics that matter. The comfort of the veranda also passes - largely - through the roof. This isolates us more or less from light, heat and cold, but also the sound of rain. Designed to be totally waterproof and airtight, it must also ensure our security in resistant to climatic and environmental hazards : wind, weight of snow, shocks, etc. Other criteria are also to be taken into account, such as the local architectural style, the orientation of the veranda, etc. So many points to check upstream with the builder in charge of the project.

Classic, sloped roof

Offering a wide range of architectures, it allows you to conserve an aesthetic harmony with the rest of the house. We can choose a single, sober and modern roof, or prefer a model with two, three or four sides, even opt for more complex shapes, tailor-made. The faceted veranda, also called "radiant", is characterized by a central beam that bears on the wall of the house and separates into chevrons to draw a star.The roof is then made of rectangular panels along the beam and then triangular panels forming an arc. The roof of the Victorian veranda, with triangular glazing, takes it, directly support the house. Like a jewel, it allows to capture a maximum of light.

Trend, flat roof

With its contemporary lines, the extension to flat roof is becoming more and more followers. It combines perfectly with modern homes but can also create an interesting game of contrasts with a dwelling of traditional architecture. On the garden side, the flat roof is enclosed by a curved or straight aluminum peripheral gutter, for a minimalist aesthetic. It allows the evacuation of rainwater, provided by descents integrated into the posts of the veranda. Like a headband, the gutter masks the very slight inclination of the roof and can accommodate shutters or even sliding blinds with fixed blades. On the inside, the flat, opaque roof consists ofthick thermal and acoustic insulation panels, covered with a waterproofing membrane. It often hosts recessed light spots and a skylight, for zenith lighting and a view of the sky. Custom designed for your lighting needs, the well can be square or rectangular, flat or domed with four sides.

The veranda "Luciole" has a roof terrace with tubular rafters with thermal break. Similar to exposed beams, these incorporate light spots.

What sunscreen?

The glazed roofs can be equipped with interior blindssliding between the rafters (Reflex'Sol). Custom designed, they let in the light while returning the rays of the sun to the outside with their metallized face. Skylights of flat roofs often require, too, a protection : sunblind blades or roller blinds on rails (models "Evada" or "Zenit", Reflex'Sol).

The "Oasis" blinds provide sun protection and thermal insulation of this veranda. Each one maneuvers independently of the others and can be stopped at the desired position, for a perfect control of the light.


Tubular or spine roof?

Sloped roof of an aluminum veranda a different aesthetic depending on the type of rafters chosen. Tubular rafters are visible in relief from the interior of the veranda, reminding the wooden frames. They allow to embed light spots and facilitate the installation of blinds. The chevrons in thorn they are protruding on the outside and flush on the inside, thus offering a perfectly smooth internal facade. It is possible to add a hood on the inner part to integrate luminaires. IPN chevrons, solid or perforated, have a straight design that gives the veranda an industrial look like an artist's workshop ("Factory Spirit", "Wallis &" range from Profiles Systèmes).

Glass for maximum light

The glazed roof offers an extraordinary view of the sky and the impression of live in nature, while guaranteeing maximum brightness. She is welcome in the verandas north or north-east orientedbecause it optimizes solar gains in winter. Choose imperatively double glazing with reinforced thermal insulation, laminated to avoid dangerous bursts in case of falling object on the roof. Oriented verandas south or south-westt can also be equipped with a glass roof. But in order to avoid the greenhouse effect on sunny days, it is necessary to bring anti-heat blinds (see box) or provide solar control glazing ("Planistar Sun" of Saint-Gobain). It allows the light to penetrate while blocking the heat; as a bonus, he reduces the noise of the rain. To facilitate the maintenance of the roof, consider self-cleaning glass : sunlight breaks down soils, which are then removed by rainwater ("Bioclean" from Saint-Gobain).

Opaque panels for insulation

The trend is with mixed roofs, which combine panels glazed and opaque, thus guaranteeing a good compromise between brightness and thermal and phonic performance. The opaque panels, called "sandwiches", are more or less thick depending on the degree of insulation required. Other possible material on the roof, polycarbonate is reserved for verandas frequented only in good weather. Translucent, light and economical, it lets the light through but resonates in the rain.
