To protect the roof today, can be used a variety of materials.One of the most popular is undoubtedly the metal profile (profiled).It is made by cold rolled steel high marks.Make the roof of the metal sheets, if desired, can be their own hands, as one of the undoubted advantages of this material is easy to install.Corrugated board can be used for roofs of all sizes and configurations.Today, such a roof can be seen everywhere.
What is profiled
Profiled is a plate of relatively thin metal (0.5 to 1 mm), coated with a polymer layer.Its surface is made in the form of waves.Dimensions of metal sheets for the roof can be very different.When choosing the material species is first necessary to pay attention on the wave height and thickness used for its production of metal.
Main advantages of corrugated
The main advantages of metal sheets, in addition to ease of installation sheets include:
- light weight (from 3 to 20 kg);
- fire resistance;
- ecological purity (metal profile is completely safe for human health);
- durability (sheets of this material are not afraid of exposure to ultraviolet radiation, temperature changes, acid rain, and so on. D.);
- cheapness (profiles - one of the most inexpensive materials to date);
- aesthetic appeal;
- a high degree of strength;
- the opportunity to reuse.
metal sheets
Disadvantages The disadvantages of this material is attributed primarily noise.However, when using a sufficiently thick heat-insulating layer, which in this case can be regarded as the noise insulation and the consequences of such a drawback can be reduced to almost zero.
if damaged outer decorative layer on the sheets can develop corrosion.Some disadvantage is the fact that by arranging the roof of metal sheets, it is necessary to follow very closely to ensure that the joints between the elements were as sealed.Otherwise, the finished roof will leak.
Varieties material
If we talk about the application, there are three kinds of metal sheets:
- Material grade "C".It is used for finishing walls.
- Profiled "H".It has the most high strength characteristics and can be used for the device of the roof.
- material mark "NA."It can be used for the device of fences, walls, and roof protection.
Actually decking - is the cheapest kind of metal sheets.Besides him there are metal - very aesthetic and practical material.Roofs covered by it, look just fine.Thus, decking and metal - are the main types of metal sheets for roofs.
Milestones in the device of this type of roof
Installation of roofing metal sheets is performed in several stages:
- roof system;
- installation of a vapor barrier;
- attaching insulating material, the most commonly used mineral wool;
- installation of the waterproofing layer;
- the groundworks;
- installation of drainage system;
- installation sheet metal sheets;
- sheathing from the attic rafters.
steam-, hydro- and thermal insulation in this case arranged in the same way as for any other roofing material.Crate stuffed with the size of sheets of metal sheets.
Installing drainage system
Before starting the installation of the roof of metal sheets, it is advisable to arrange a gutter system.At the first stage fixed crate holders gutter.The edge of the latter is to be eventually located approximately 3 cm below the future roof.Otherwise, you may strain when the snow melts in the winter.After the holders are installed, they inserted a gutter.Next to the sheathing attached Cornice strip.Its installation is performed so that was blocked by the edge of the gutter.Also over the precipitous plank will need to bring the edge of the waterproofing film.
Calculation of roofing metal sheets
roofing metal sheets with their own hands will be arranged with the savings in the event that will be made the necessary calculations.In this regard, first of all, it takes into account:
- number of elements in a horizontal row.For this pre-measured length of the roof.Of course, in the horizontal direction, respectively.The resulting figure is divided by the width of the sheet.Also take into account the length of the overlap between the elements.
- To calculate the length of the sheet and the number of rows you need to ramp length (vertical) to add the length of overlap, as well as the length of the overhang of the cornice.
To find out how much you will need screws, you need to calculate the area of the roof of the future, and the resulting figure is multiplied by 6.
Preparation tools and materials
Before installation of the roof, you need to prepare the tools.At hand should be:
- building level and a plumb;
- metal shears or jigsaw needed for nesting;
- electric;
- pencil and square;
- screwdriver;
- screws.
himself profiled should be transported and lifted to the roof with maximum accuracy.Otherwise, you can damage the protective polymer layer.
Installation sheets stingrays
Now let's see how actually arranged roofing metal sheets by hand.Mounting plates start from the bottom.They are fixed to the sheathing screws at the bottom of the wave.This will ensure the reliability of the installation.The overlap must be carried out with at least one wave.On one 1m2 roof must be at least 6-7 screws.Horizontal overlap (between rows) should be about 20 cm.
Facing gable
The production rate of necessary for facing gable material is taken into account exactly how it will be laid.The most economical method of installation is considered to be horizontal.In addition, in this case, the house will look more aesthetically pleasing.The calculation should take into account the fact that prirezku takes about 10-15% of the material.
quite suitable for the gable wall profiled brand "C".It is also possible to use material of "H" and "NA".After the heat and waterproofing mounted skeleton of wooden slats.They will need to pre-fix windproof film.Steel sheet is cut with a hacksaw or jigsaw for metal.
arranging the roof of metal sheets, you have to be very careful in terms of the possibility of damage to the polymer coating.Otherwise, it will be significantly reduced lines of the structure, because the elements over time will begin to rust.Therefore, use a grinder to cut the sheets are not recommended.Attach the cut steel sheet to the frame should start with a lower angle.All the elements are mounted overlapping.
Installation skate
Roof installation of metal sheets also includes the installation of the ridge.Joint top of the ramps closed already prefabricated elements, which can be purchased at the same time buying sheets.Manufactured horse from the same material as the main elements.We need it to prevent the ingress of water under the sheets.Laying in this case should be started to perform the opposite direction of the prevailing wind side of a particular locality.Ridge elements are mounted with overlap of 15-20 cm in the comb with a pitch of 20-30 cm. For fixing screws are also used.
In that case, if the angle of slope of the roof is low, under the ridge elements should put a special seal, which can also be purchased at the hardware store.Between him and the ridge vent must remain a small gap.
Installation valley
When mounting the roof of metal sheets, it is necessary among other things to set right the valley.In this case, good sealing is very important.The valley is called the gutter, included in the internal oblique intersection of the ramp.Mounted on a solid crate it, arranged on both sides.Horizontal elements connected with overlap of 10-15 cm. Designated joints compulsorily treated with sealant.In order to better adjoined endovnaya strap to the roof, you should use special self-expanding sealant.
At the moment, it seems more than appropriate to use to protect the roof of such a modern material such as metal profile.Installation of the roof in this case can be performed in a short time and without the involvement of professionals.For little money home owners get protection of its internal space of all adverse environmental factors.
