One of the methods for self-sealing a round pipe on a metal roof is shown in the video:
Square tube
It is very rare to find ideally suitable ready-made elements offered for sale for the arrangement of square and rectangular pipes. Depending on the type of roofing material, the methods for arranging the junction of the pipe to the roof are selected.
An important point in the arrangement of the chimney is its high-quality connection with other elements of the roof, namely the sheathing. If this condition is not met, then additional rigidity is provided by installing a special element - a metal sheet.
When performing installation work, partial dismantling of the roof lathing is often required. In this case, to ensure the rigidity of the structure, a frame made of wooden beams is mounted around the pipe, to which layers of waterproofing and vapor barrier are attached. Waterproofing is attached to the lathing and counter-lathing. Vapor barrier is laid between the roof frame and internal finishing materials. The space between the frame and the pipe must be filled, according to SNiP standards, with non-combustible thermal insulation material - stone wool.
Important! Pay special attention to the quality of sealing of the joint of the vertical element with the roofing material. There should be no leaks at the points of their connection.
Tiles
On a roof covered with ceramic tiles, the arrangement of the chimney adjoining places is carried out using elastic tapes, which are made of aluminum alloy, with an adhesive layer finland mobile database one side. Such a tape is attached along the perimeter of the entire seam, while partially adjoining the chimney, partially to the roof, smoothly repeating the existing bends on the tiles. Then the part that is glued to the chimney is fixed with a metal profile strip, using dowels made of heat-resistant material. The joint must be properly treated with a sealant.
The arrangement of the joint when roofing with flexible tiles is carried out using a similar technology, but the metal tape is replaced by a valley carpet, or a row-type tile, previously inserted into the chimneMany houses, especially multi-story ones, are equipped with a special parapet on the roof. The height of such a structure may vary, but in any case it will be connected to the roof covering. In the article below, we will tell you what the device of abutments of soft roofing to parapets is and what standards should be observed during installation.
Parapet structure
By design, a parapet is a low wall built along the perimeter of the roof, which not only performs a protective function, but also serves as a decorative element. A parapet can be erected on both flat and pitched roofs. If the roof is flat, it is completely enclosed by the parapet wall.
