Description

Title of the invention: Method for sealing a hole in a roof Scope of the invention

[0001] The present invention relates to the field of emergency roof repairs after damage caused by a disaster such as a storm or hail in order to secure and protect a building and prevent water infiltration into the roof and ensure immediate waterproofing.

[0002] Roofs are susceptible to damage from strong winds, rain, or hail. Tiled or slate roofs may have a considerable surface area of ​​tiles damaged by hail impact or completely dislodged following severe thunderstorms. Damage to roofs can also be caused by the impact of falling trees, large branches, or other objects propelled through the air by strong winds.

[0003] Damage caused by a storm or impact cannot usually be repaired immediately, so it is impossible to avoid further or potential damage inside the building. Temporary covering must then be provided. Generally, canvas tarpaulins (or tarpaulins of similar material) are placed over the damaged part of the roof and secured to the structure with ropes.

[0004] One drawback of this temporary covering method is the difficulty of properly securing a tarpaulin to the roof. Tarpaulins often require repeated attention and adjustment. Furthermore, they are heavy and difficult to position, which poses health and safety problems in the workplace.

[0005] Another disadvantage is that they are expensive to acquire and bulky to store, and if many roofs are damaged during a storm, the number of tarpaulins available may be insufficient. State of the art

[0006] A roof covering system with a film material proposed in U.S. Patent 2005 / 0217202 describes a method of applying the film from a roll of film hoisted onto the roof, the film being unrolled in situ with the overlapping edges of the film secured by applying adhesive tape. The film rolls are heavy, and in practice, handling a roll of film and taping the edges is difficult, even dangerous. The material is in the form of a flexible plastic film such as polyethylene.

[0007] US patent 11168484 describes a method for providing coverings on at least a portion of a roof of a storm-damaged structure comprising the following steps: - apply a sheet of heat-shrink film to the part of the roof, the sheet having a leading edge and a trailing edge and being a low-density polyethylene film comprising shrink resins; - wrap parts of the leading edge around a first slat and fix the first slat to an underside of a first overhang or to a facade of the constructed structure; - wrap sections of the trailing edge around a second batten and attach the second batten to the underside of a second eaves or to the facade of the structure built in a different location than the first batten; and - heat the heat shrink film sheet to bring the film into conformity with the part of the roof, in which said heating step shrinks the film sheet tightly against the structure built to cover the part of the roof.

[0008] US patent 1177361 relates to a protective roof tarp comprising one or more deformable and foldable adhesive tapes configured to maintain continuous adhesion to both a barrel-shaped roof tile and a flat-shaped roof tile having granules fixed to an upper surface thereof such that the adhesive material penetrates beyond the granules and engages with a roof tile substrate below to effectively prevent water from flowing under the protective tarp and onto the roof for prolonged periods and in adverse weather conditions.

[0009] US patent 10246889 describes another strap anchoring system for emergency roof tarp installations, comprising at least one strap assembly, the upper face of which has an upper cutout and an upper cutout face, and the lower face of which has a lower cutout and a lower cutout face, and a retaining strap, in which at least one strap assembly secures a tarp to a roof.

[0010] Patent application EP2313576 describes a cover for a damaged or unfinished building; said cover comprising a film of heat-shrinkable material stretched over a damaged building or roof; said film formed in the form of a sheet comprising an assembly of lengths of said heat-shrinkable material prepared on a ground surface. Disadvantage of prior art

[0011] Prior art solutions are not entirely satisfactory because they require the handling of heavy, bulky, and difficult-to-handle tarpaulins or rolls of film They are installed on a roof, especially one weakened after a weather event. Furthermore, the connection between these tarpaulins and the roof is susceptible to wind infiltration, which can lead to the tarpaulins or canvases being torn off. Solution provided by the invention

[0012] The object of the present invention is to remedy, or at least mitigate, some of the above-mentioned drawbacks. To this end, it relates to a method for sealing a hole in a roof made up of roofing elements fixed to battens, characterized in that it comprises the following steps: a. A step of cutting a membrane to the dimensions of said hole plus a strip to cover the roofing elements adjacent to said hole. b. A step of mechanically fixing said membrane to the battens. c. A step of coating said membrane with an elastomeric resin and of a peripheral band.

[0013] According to one variant, said membrane is made up of a mesh.

[0014] Advantageously, said wire mesh has meshes with a cross-section between 1 and 10 mm2.

[0015] According to another variant, said membrane is made up of a vapor barrier film.

[0016] Advantageously, said resin is a polyurethane resin.

[0017] According to a particular embodiment, the method includes an additional fixing step consisting of gluing the cover strip onto the peripheral cover elements of said hole.

[0018] According to a particular embodiment, the process includes an additional step of covering the upper edge of the cut membrane with a row of cover elements.

[0019] Detailed description of a non-limiting example of embodiment

[0020] The present invention will be better understood upon reading the following description, concerning a non-limiting example of an embodiment illustrated by the accompanying drawings where:

[0021] Figure [Fig. 1] is a schematic view of a roof before caulking according to the invention

[0022] Figure [Fig.2] is a schematic view of the roof after caulking according to the invention.

[0023] Detailed description of a non-limiting example of the invention

[0024] The invention relates to the implementation of emergency measures for sealing holes in roofs following severe weather, to ensure rapid waterproofing before subsequent repair work, using a support material such as a membrane, wire mesh or vapor barrier film, coated after mechanical fixing to the battens with an elastomeric resin.

[0025] The invention relates more particularly to roofs formed by roofing elements (1), in particular tiles or slates, fixed on battens (2) fixed on the framework or of fiber cement panels laid on a metal framework joist system.

[0026] The process consists of removing the torn-off roofing elements and removing all debris, to clear a hole (3) free of debris, revealing the network of battens (2).

[0027] Preferably, a horizontal row of covering elements is placed on the sound part, above the hole (3).

[0028] A membrane (4) is then cut to the dimensions of the hole to be repaired, with a sufficient overlap to cover the adjacent roofing elements. The dimensions of the cut correspond to the dimensions of the hole (3) plus a peripheral strip approximately twenty centimeters wide, typically between 10 and 30 cm.

[0029] This membrane (4) is typically a fine mesh wire, with a surface area of ​​approximately 1 to 10 mm2, metallic or polymer, or a vapor barrier film.

[0030] The cut membrane (4) is then mechanically fixed to the roof battens, for example using nails (5) or staples. The peripheral edge (6) of the membrane (4) is optionally glued to the roofing elements adjacent to the hole (3).

[0031] The membrane (4) thus fixed is then coated with an elastomeric resin, which is also applied to a peripheral strip around the membrane (4), thereby reinforcing the watertightness of the repair. The resin is typically a polyurethane resin, for example from the brand PORYUREA™ with an overlap of 20 cm to 30 cm beyond the size of the membrane (4).

[0032] Finally, an additional step involves covering the upper edge of the membrane (4) with a new row of cover elements, which adds an additional layer of protection.

[0033] This process therefore makes it possible to carry out a temporary or semi-permanent repair of damaged roofs in a relatively simple way, while ensuring good waterproofing.
