The roof of modern houses, as a rule, consists of several parts: vapor barrier, insulation and waterproofing, due to which they are provided with sufficient protection from cold weather and strong winds. Nevertheless, on almost any roof, there are still places where leaks often occur. To prevent this, a special chimney apron is required to ensure complete roof sealing.
Description and purpose
One of the most common problems faced by owners of country houses is condensation that accumulates in the chimney. The cause of its occurrence is temperature drops. Gradually, it accumulates, after which it flows down the entire chimney, thereby making it difficult for the pipe to work and causing many problems to the owner of the house. In the end, this can lead to the fact that the pipe simply collapses.
A similar problem occurs when using a chimney. During combustion, the pipe becomes very hot, and if at this moment it comes into contact with any moisture, this can lead to a deterioration in draft. As a result, the chimney deteriorates and may soon become unusable. In order to prevent this, it is necessary to provide the chimney with proper sealing, which can be achieved by installing a high-quality chimney apron.
The apron itself is simple and effective to use . The outer walls of the pipe on the roof are supplemented with waterproofing and vapor barrier material, fastened with ordinary tape. Then a small groove is made around the perimeter of the chimney, where the upper bar should soon be placed. After all these works, a special waterproofing tie is fixed under the apron itself, which protects the chimney from future leaks.
This design itself works very simply: the apron removes most of the water from the pipe, and even if some moisture has passed through it, it will not enter the pipe, but drain from the roof, without interfering with the operation of the chimney. It is suitable both for metal tiles and for any other roofing material.
Varieties
There are many varieties of aprons, each suitable for a completely different environment . You need to choose it based on the size of the chimney itself, paying attention to the pipe material. The personal preferences of the buyer himself play an equally important role. It should also be remembered that you need to buy aprons only from trusted manufacturers, since buying a low-quality fixture can lead to serious damage to the outer and inner walls of the chimney .… The most popular are metal aprons and brick models.
One of the best examples is the stainless steel apron . They are produced in completely different diameters so that they fit any type of pipe - from 115 mm to options with a diameter of 200 mm. In addition to the main function of protecting the chimney from moisture entering the chimney, it is also widely used as a roof seal and for decorative purposes. Optionally, in addition to the apron, you can put a film under the slate for greater sealing.
For similar purposes, a silicone pipe skirt is used, which is a similar device designed to protect the chimney from moisture entering the surface of the chimney pipe
Another popular option is rubber apron. It is durable and easy to install. Due to the density of this material, the pipe will be reliably protected from any precipitation, allowing the owner to save time and nerves.
The aprons also differ depending on the shape of the pipe. So, for a round pipe, special types of aprons are sold from completely different materials, suitable for any type of chimney. As for the material, they can be both metal and rubber.
How to do it yourself and install?
You can buy a chimney apron in a store or make it yourself. This does not require any special tools or knowledge. To do this, it is enough to have the necessary materials and have drawings on hand. You will need a small hammer, pliers or pliers, and metal scissors. In addition, a ruler, marker, pencil and metal bar will come in handy.
The device itself is made without much difficulty. Four blanks need to be cut out of metal, after which their edges need to be slightly bent with pliers. It is these edges that will be the connection lines for these parts. The edges of one piece must be bent to the inside, and the edges of the other, on the contrary, to the outside. Then they need to be bent a little, and then connected with a hammer. It is advisable to do everything according to the instructions so that the process is clear, and no mistakes are made during it. If everything has been done correctly, the apron should be ready for use. As you can see, there is nothing complicated in the production itself.
The process of installing an apron should also be easy . First you need to cover the roof by laying the tiles so that they are close to the pipe. As a result of these actions, the apron should rest on one of the tiles. A thick layer of roofing cement is applied to the edges of the apron. The collar of the apron itself is worn around the ventilation pipe. It is necessary to ensure that the metal adheres tightly to the surface. To fix the apron, you need to nail it around the perimeter with nails for the roof. The gap between the apron collar and the ventilation pipe is sealed. Then you need to cut out the tile and overlay it on the top of the apron. Between the tiles and the apron, cement must be applied. Nothing else is required, because now the chimney is reliably protected from moisture and condensation, and the owner of the house himself does not have to fear for the safety of his chimney.
Finally, I need to mention about the importance of exactly following all points of the instructions . If the sealing of the pipe was not carried out successfully, then in the future the chimney will suffer greatly from this. Leaks will appear, due to the abundance of moisture, the frame will begin to rot, and the metal of the roof will be covered with corrosion. Subsequently, all this can result in damage to the entire roof, so you need to install the apron correctly.
If you are not sure that you will be able to do all the work without errors, then it is best to contact a specialist.
