Cold roof improvement

Currently, in newspapers and online sites that provide information related to construction, a large number of suggestions for the provision of services providing roofing for country houses and country cottages are placed.

In most cases, they mean insulated roof, which is often called roofing pie. At the same time, there are almost no mention of the cold roof. And completely in vain, since it is it that is the optimal solution, especially for some kind of buildings. In addition, this is a very affordable option for wide circles of the population in terms of its value.
This article has a goal, to convey information about what cases it is better to install cold roof and how to implement it.

Usually, the solution to establish a cold roof is due to material considerations or a lack of great need in a warm roof. As an example, you can mention the construction of a country house, in which the attic room is not planned. In this case, there is no need to carry out the insulation of the attic. Such an option is acceptable for economic buildings, for which it is enough to insulate only the ceiling, leaving the roof of the cold. Such an example can also serve modular homes composed of block containers. Modules themselves are insulated by themselves. It is only required to install a cold roof. It is quite clear that such a kind of roof is quite suitable for country buildings, canopies, arbors, lounges for recreation and other structures. In the countryside of the house, as a rule, not residential attics and, accordingly, cold roof, which allows to save significant funds.

What is a cold roof?

In constructive plan cold roofing Does not represent any difficulties. To protect the space of an attic from condensate, which occurs on the inner surface of the roof, a membrane with waterproofing properties or a film is fixed on rafters.
Before installing the roofing coating, feed the crate and the crate. Under the skate and on the rods, outputs are installed through which water vapor is outlined from the space under the roof. In addition, the auditory windows also serve to ventilate the attic room. The lack of difficulties during installation and subsequent operation of the cold roof are caused by the simplicity of its design.
In the case when it is planned to further produce insulation of a attic or making a attic, it is necessary to use for waterproofing the type TYVEK membrane, since a micro perforated film, which is usually used when installing cold roofs, does not allow the necessary density of the insulation adjustment density.
If the roof is not insulated, it is quite possible to use the use of a micro perforated film with a smaller value. Its installation provides provisis in 20 mm, which provides water flow in the middle of the run and protects rafters from moisturizing. Waterproofing in the area of \u200b\u200bthe skate is broken to ensure the exit for air.
There is an opinion that in the regions where harsh winters are marked, the cold roof does not make sense. It is worth noting that it is wrong. The history of the cold roof equipment and the attic is not one hundred years. The use of such roofs is possible in any terrain. It is only necessary to observe the conditions for the insulation of the attic overlap, which are required by the norms of this area of \u200b\u200bresidence. In regions where great indications of negative temperatures are noted, special attention should be paid to the insulation of technological equipment, which will avoid condensate, which will inevitably lead to icing.
A variety that do not require the installation of a solid base can be applied as a cold roof coating. The use of or profiled sheet will be quite a prosecutor. They are distinguished by reliability, manufacturability and durability. Those that have a polymer coating are especially recommended, which makes it possible to significantly increase the service life of the roof.
An example is the steel coated with ColorCoat, which is produced in England by Tata Steel. The warranty period is 20 years, while really such a roof will serve not less than 50. For those who believe that the profiled sheet does not meet their aesthetic requests, it is possible to recommend the use of metal tile. Externally, it is similar to genuine and at the same time differs by a low weight and lack of difficulties during installation.

Or maybe even easier?

Of course, this is quite possible, especially if it is necessary to install the roof on the construction, which will not need insulation. The use of a profiled steel sheet with an anti condensate coating will largely simplify the conduct of installation work, reduce the cost.
This material has a synthetic felt structure, which is applied during the manufacturing process on the purned surface of the profiled sheet. Weaving polyester fibers creates air cavities in a huge amount. Such a structure gives the coating the ability to accumulate and retain a large amount of moisture, the value of which can reach 1 l per m2. Increased air temperature leads to intense evaporation of water.
In this way, it is possible to solve the condensate problem, which appears on the inner surface of the roof and does not use waterproofing. And although in this case there is some increase in the cost of roofing material, it is compensated by the absence of the need to install the crate, carry out the installation of a waterproofing film, a reduction in the time required for installation, almost 2 times. At the same time, it is achieved to facilitate the prophylactic inspections and the current repair of the roof.
Installation of the roof from an anti-condensate coating is similar to the work using the usual professional flooring. It does not require the use of special tools and the presence of certain skills. As a result, the use of this material to install the roof can reach 30% of savings from the estimated cost.
The use of an anti condensate coating can be a find for those who set the roof on buildings that do not have an attic overlap. For the most part, this concerns buildings having a single-sided roof. It may be verandas, garages, canopies, arbors. They will not need to use the film to ensure waterproofing. All other advantages of this type of cover can be added to weaken wind noise, rain and hail, on average for 2 dB, easy purification from contamination, no fungus and mold.
Opportunities for original solutions
Nowadays, the market for construction materials is so diverse that for those who wish to give the original appearance of their roof, practically nothing is impossible. This statement can be attributed to a cold roof. The arrival of a large amount of light on the attic, a veranda or in a gazebo will provide the installation of transparent inserts made of profiled polycarbonate. And canopies, if they have small sizes and can be completely transparent at all.
The dignity of the profiled sheet made of polycarbonate is undoubtedly its ability to skip light, which is preserved for 10 years of operation. It is possible to add high resistance to low temperatures and mechanical exposure, the ability to reduce the intensity of ultraviolet radiation.
For a cold roof, an interesting solution can be setting in non-residential premises of the windows, the purpose of which is to use as emergency exits. The installation of a number of such windows in the attic will allow them as a dining veranda or solarium. It is very convenient to sit in it during the weather. Such an option will have to, by the way, those who have the dimensions of the site do not allow to install the gazebo.

Cold roofingwhere the design features and the ability to apply modern solutions and materials find their combination, make it possible to consider it almost an ideal option in the construction of cottages and country houses. Otherwise, its installation on the pocket to any ordinary consumer.
