Today, more and more people are striving to replace ordinary slate with a strong and durable metal tile. The roof of this material looks presentable. The metal tile is a steel sheet of various geometric shapes and colors. It has gained its popularity due to its many positive properties.
The main rule in the construction of this element is compliance with all building codes, that is, installation rules must be strictly observed, and specialized materials must be used. In this case, the roofing cake under the metal tile will have heat and sound insulating properties.
Professionals often do the installation of metal tiles, as this is a laborious process. Each seam must be rolled to ensure the strength and tightness of the entire roof.
Basic information
Metal tile is a common roofingmaterial. She gained her popularity thanks to:
- high performance;
- low cost;
- attractive appearance.
There are different types of metal tiles, each of which has a different profile and protective coating. The last factor affects the durability of the roofing material.
To create a warm and waterproof roof, one metal tile will not be enough. In this case, it is necessary to use other materials that provide heat and vapor barrier for the entire structure. These can be found at any hardware store.
When choosing a metal tile, it is necessary to pay attention to protective pollination. It protects the material from the negative effects of the external environment. As a protective layer, passivating and polymer mixtures are used. They not only prolong the service life, but also give a pleasant appearance to the structure.
Roofing cake for metal tiles: installation order
To create the right roofing cake, you need at least three materials. The main layer is a metal tile. It must not be adjacent to other elements. In this case, an air gap is formed, which serves as natural ventilation.
Roofing cake for metal tiles, the order of formation of which has several technologies, must be formed after careful selection of materials. The best place to start is with thermal insulation.
Installation instructions itselfcontains several steps:
- First, the vapor barrier is attached to the inside of the rafters. To do this, use a construction stapler.
- Next, the insulation is laid. It will be located between the lags on the outside.
- Then waterproofing is done. It is laid from bottom to top along the slopes. For the installation of waterproofing, a construction stapler is also used.
- After that, the bars of the counter-lattice are attached along the axis of the rafter legs.
- Boards or bars are stuffed over the crate. In places of ridges and other junctions, a continuous crate should be used.
After that, you can already proceed with the installation of the roof itself. When performing all work, maximum safety must be ensured, since the operation is performed at height.
Workers must use safety harnesses and keep all tools in the belt.
Main Ingredients
Roofing cake has a complex structure. Each layer performs a specific function. The device of the roofing pie under the metal tile is as follows:
- outer coating - weather protection;
- vibration isolation absorbs any noise caused by external factors;
- sheathing - the main element made of wooden elements;
- counter-lattice - a wooden device used as ventilation;
- waterproofing - a system that protects against moisture penetration;
- ventilation gap serves to get rid of moisture;
- rafters;
- vapor barrier - a layer that protects the rafters and thermal insulation from moisture penetration;
- attic interior decorative cladding.
Roofing cake for metal tiles with a cold attic
Building a roofing cake for cold rooms doesn't take long. Many people prefer the budget option, which means shingles, battens and cheap waterproofing. As the last layer, use plastic wrap.
Roofing cake for metal tiles, the instructions for the formation of which are described in the article, begin to be made by fixing the waterproofing layer to the crate. This is done using a construction stapler and thin nails. For additional fixation, you can use self-tapping screws, which will later hold the batten.
Pay attention! The waterproofing film is not attached with a stretch, but with a slight sag. This contributes to the timely removal of condensate.
Insulated roof installation
Roofing cake under metal tiles with an insulated roof implies the use of additional materials, which were discussed above. A properly formed cake allows you to create comfortable living conditions in a house or apartment. The waterproofing material is attached to the crate with a slight sag. The crate serves to hold the metal tile. During its construction, a different step of the boards can be used, depending on the angle of inclination of the slope.
Before starting the formation of the roofing cake and the construction of the roof, you must carefully study the instructions that are provided with the material. There are many manufacturers of metal tiles. According to personal preference, you can choose the appropriate type, size and color of the product.
When building a roof, don't skimp on materials. The quality of heat and sound insulation depends on them. The truss system must withstand heavy loads - snow cover and people who are repairing the roof.
Let's take a closer look at the roofing cake for metal tiles, the characteristics and basic properties of the layers.
Outer Coating
Exterior cladding is a popular roofing option as it has many positives. Properly installed material will last a long time and will not need constant repairs. There are many manufacturers of this coating. Sealing gaskets are used to create tightness between the wall and roof elements. They are of two types: hard and soft. This item is purchased together with a metal tile.
A prerequisite is the installation of a soundproof layer. The sound of rain or wind will transmit vibration to the building structure and cause an unpleasant effect. To avoid this situation, a vibration-proof layer is mounted on top of the crate near the fasteners.
Crate functions
Roofing cake under the metal tile is built on a special wooden crate. It is a frame and serves to distributeloads throughout the truss system. Many manufacturers regulate the value of the crate step, which is 300-350 mm. This parameter depends on the angle of the roof. The smaller it is, the shorter the crate step should be.
Pay attention! The crate and counter-crate must be treated with an antiseptic. This is necessary to increase the life of the material.
Waterproofing
When building a roofing cake, a prerequisite is the presence of a waterproofing material. This element performs the following functions:
- protects against moisture on the rafters;
- prevents the formation of moisture on the surface of thermal insulation;
- reliably protects the building structure from other damage.
The most suitable material is with anti-condensation membranes. They are mounted to the rafter legs using a conventional stapler. A crate and a counter-crate are laid on top. The membranes not only have good waterproof properties, but are also resistant to UV rays.
Questions on heat and sound insulation
In the roofing cake must be present insulating material. It is mounted between the rafters and prevents the penetration of cold air. Noise isolation also plays an important role, since this type of roof belongs to the loud class.
As insulationmineral wool materials of varying degrees of hardness are used. In practice, it is better to use a material with low thermal conductivity and high sound insulation. The most suitable option is semi-rigid insulation made of glass wool.
Additional information
If a fibrous thermal insulation material is used, it is necessary to provide a gap between it and the waterproofing layer.
The following materials are used as thermal insulation material:
- foam sheets;
- mineral wool bas alt sheets;
- glass wool;
- styrofoam.
Roof vapor barrier
The vapor barrier layer prevents moisture from entering the living quarters and onto the elements of the roofing system. To ensure this, vapor barrier is placed over the entire surface of the roof. After that, proceed to the inner lining. It is made of wood or drywall.
Conclusion
Metal tile is one of the common roofing materials. In order for it to provide comfortable living conditions indoors for a long time, it is necessary to form a roofing pie. It consists of different layers, each of which has a specific function. It is worth noting that for a cold and warm roof, the order of formation is different. In the first case, you can simplify the design by using only waterproofing and tiles. Warm roofs require the presence of all components: heat, hydro and sound insulation. Before the formationroofing cake, you should familiarize yourself with the technical characteristics of the materials and with the instructions for their installation.
