The hinged roof is a four-sided roof in which the gables are replaced by hips. The frame and roofing are adapted accordingly. The hinged roof is very commonly used for single-family dwellings.
Let’s have a look at the different types of roof structure
In traditional carpentry, purlins and rafters come to rest on farms. The whole provides the necessary grid to support the roof. In the industrial framework, prefabricated elements are triangulated and assembled by connectors. Each triangle is a complete truss that will give the roof the slope visible from the outside.
The industrial timber frame has become very widespread, offering an accessible price and ease of installation, which can sometimes make it a possible approach for a good DIY. On the other hand, it has the disadvantage of making the attic uninhabitable, unless subsequent heavy work is carried out.
Comparison between the hinged roof (4-sided) and the gable roof (2-sided)
The four-sided roof takes up the elements of the two-sided roof. In a gable roof, on the other hand, the side load-bearing walls rise up to the roof ridge, forming a gable. The two main slopes of the gable roof do not, of course, stop at the side walls. The gable section is itself cut at an angle, the ridge being shorter than the base. Rumps will close each side plane, forming a slope. The part forming the junction between the two sides is called the hip.
As with the gable, the roof for the gable can be straight (single line of slope on the entire slope) or broken (change of the line of a slope at one point of the slope).
Roofing on a hinged roof (4-sided)
The roofing elements are beveled at the hip to form the angle. The water tightness at the hip is ensured by hip tiles which cover the protruding angle over the entire height of the hip.
It is possible (if permitted by the municipal by-law) to make the gable section in one tile color and the two hip sections with the same roofing elements but in a different color.
Special features of a hinged roof
A four-sided roof gives your building a sophisticated look. However, it can be more expensive, especially because it may require more time and technicality for its implementation. It has the advantage of better wind resistance than a gable perpendicular to the ground. The hinged roof is therefore well suited to windy regions.
If your attic must be convertible, the structure is a little more complex than a simple gable roof. Maintenance is done annually, to rid the roof of plant waste, dirt, etc… The corner lines (especially the inward-facing ones) must be carefully cleaned.
Roofing accessories and additional equipment
In order to keep the harmony of the four sides, it is essential that the elements that come above the cover are well-positioned. If you choose to equip your roof with photovoltaic or thermal solar energy, this equipment should be put in the center on one side. While being shifted towards one of the crests, it will tilt the overall impression towards one end.
To reinforce the waterproofing, you can add a bituminous strip on the hip, before covering it with the hip tiles. When you have a re-entrant angle, for example, if you lay a dormer covered with a two-sided cover, you must make a notch under the joint line. This allows the infiltrated water to be channeled into the drainage system.
Price of a gable roof
It is very variable according to the complexity of the roof, the type of framework (traditional or trusses) and the roofing. To get an idea, count from $150 to $300 per m² (excluding VAT) for a frame + four-sided roof supplied and installed by a professional.
Calling on a professional for roofing work
A roof in good condition is essential to protect your home from moisture on a daily basis. Whether you are building or renovating, your roofing work should be carried out professionally.
For work as technical as roofing, it is strongly advised to call in a professional. Above all, if it is for a particular material, it is advisable to contact a specialist in this type of covering; someone who will be perfectly familiar with the rules of installation and will give you a ten-year guarantee.
