Discover all the information concerning the pitched, rounded, flat or green roof as well as the different characteristics and prices.

The choice of roofing types is one of the crucial stages of any construction or renovation project. Many factors will come into play: the type of frame, the characteristics of the habitat and local standards as well as your aesthetic preferences and your budget. The price of the roofs are highly variable. According to data from Amazing Roof Restoration, the average price of a roof is set at € 2,045 including VAT, but the price range remains wide: from € 754 to € 4,738 including VAT *. The cost of a roof depends on its shape (pitched roof or rounded roof or flat roof), as well as a number of other factors. Here is some information to help you choose the right roof.

Different types of roofing: pitched roof

Pitched roofing remains the most common style of roofing in France. It is ideal for rainy and snowy regions. Indeed, the evacuation of water is easy and depends on the degree of the slope. Calculating the minimum slope to apply to the roof is a complex operation. Indeed, account must be taken of the elements specific to the house: surface area of ​​the house, width of the roof, number of slopes, height of the gable. But, the environment of the house is also important: is it protected by hills or on the contrary exposed to the winds by the sea? The material used sometimes determines the minimum roof slope. So a thatched roof must have a slope of at least 40%. The use of flat tiles is only possible if the slope reaches at least 35 degrees. The roofing craftsman is able to perform the precise calculation of the slope of your roof , from the establishment of the estimate.

The pitched roof is generally less expensive than the rounded roof or the flat roof. However, you should know that the more sloped the roof, the more complex it is to make and the more expensive it is.

Different types of roofing: rounded roof

The rounded roof is considered an ecological roof . Indeed, it has a smaller external surface than the sloping roof. Heat losses are limited. In addition, it allows greater occupancy of the attic space. Indeed, the inhabitants of the house are not bothered by the slope. The rounded roof is suitable for all types of construction. Thus, it brings a certain harmony in the forms including for the most contemporary houses. In addition, the rounded roof allows all architectural fantasies. It can, for example, take the form of a dome, in general a spherical masonry shape, or the shape of a curvature or even the shape of an arrow (conical shape).

The rounded roof is often more expensive than the sloping roof. This additional cost is mainly due to its more complex design.

Different types of roofing: the roof terrace

The roof terrace, a flat roof, is no longer reserved for collective buildings. In fact, more and more individual houses are equipped with roof terraces . The roof terrace may be inaccessible. In this case, it is suitable for receiving photo voltaic panels or plants. But the roof terrace can also be accessed. Additional m² are thus easily gained.

The peculiarity of the roof terrace is that it does not have a frame, but a supporting structure made of wood or metal or concrete.

The price of a flat roof depends very much on the complexity of the project . In general, a green roof terrace is more expensive than a simple roof terrace. However, plants provide good thermal insulation, both in winter and in hot weather. In all cases, to install and design a roof terrace, you will have to call on a specialized roofer or even an architect.

Different types of roofing: other factors than the shape of the roofing

The shape of the roof is only one of the parameters taken into account by the construction professional, to establish his estimate. The number of square meters of your roof is of course taken into account. But other factors are also important. Thus, the traditional custom-made frame is more expensive than the farmhouse, a frame pre-made in the factory.

The other elements to take into account in the calculation to establish the budget for a roof are: insulation , the number of openings present on sloping roofs or on roofs of rounded shape, the ventilation system, the materials covers or protection, the type of screen under the roof and the rainwater evacuation system.

At the gutters, you have the choice between a creeping gutter and a hanging gutter. The more expensive creeping gutter is suitable for steep roofs.

The price ranges from simple to double, depending on whether you choose the least expensive material (PVC) or the most expensive material, but also the most solid (zinc). The installation of a screen under the roof is not compulsory, but highly recommended. Indeed, it strengthens the solidity of the roof. Several types of under-roof screens are available on the market: synthetic multi-layer and highly vapor permeable (HPV) roof screens, bituminous screens and reflective roof screens, which are more expensive but which provide real thermal comfort, in case of attic development .

What are the different types of roofing?

Insulating your roof is important, because 30% of heat loss is through the roof. The price range of insulation is very wide. The least expensive are conventional insulators, such as rock wool or glass wool. The most expensive are natural insulators, such as sheep’s wool, expanded cork or cellulose wadding. The choice of roofing material depends on the slope, your tastes, the constraints of the local urban plan (PLU), but also on your budget. Thus, the concrete tile is much cheaper than the clay tile.

The price of a roof therefore depends on its shape, but also on a multitude of factors. The roofing craftsman can help you choose the materials best suited to your roof and offering the best value for money. As with all building work, it is advisable to ask for a minimum of 3 quotes to have your roof made or renovated.
