The term “soft roof” means a direct or inverse arrangement of layers of bitumen - polymer mastics and materials based on fiberglass, fiberglass and polyester fabric.
In this article we will look at the device in winter period, And Is it possible to make a soft roof in winter??
We will also touch upon the issues of operating a soft roof in winter and removing snow from the covering.
First, let's look at existing species soft roof.
IN official documents another term is used to denote a soft roof - roll roofing.
The design and repair of soft roofs is established by a Code of Practice SP 17.13330.2011 SNiP II-26-76"Roofs".
The document classifies roll roofs as straight and inverted roofs, with an insulation layer made of bitumen, bitumen - polymer material, various membranes and mastics.
With a carpet made of rolled material with a gravel or coarse-grained topping, it varies from 1.5 to 10%, from bitumen-polymer material with coarse-grained topping - from 1.5 to 25%.
To create a slope along a horizontal base, use a cellular concrete screed monolithic installation. The screed can be laid on the base or on the insulation. It is possible to use special shaped additions made of slab insulation.
Soft roofs with a slope of ≥ 25% are performed subject to application hot mastic and rolled material with heat resistance of 90° C, or cold mastic heat resistance 100° C.
Composition of a soft roof with a direct arrangement of layers looks like this:
- Base;
- Slope-forming layer;
- Vapor barrier;
- Insulation;
- insulation from 2 – 4 layers of bitumen roofing material, upper layer has a fine- or coarse-grained topping.
Quantity insulating layers accepted taking into account technical characteristics roof material and slope
In an inversion roof, the layers are arranged in the reverse order:
- Base;
- Slope-forming screed;
- Waterproofing carpet;
- Insulation;
- Filter material;
- Load of gravel or concrete slabs.
Inversion roofing is performed on large areas and on used roofs.
Materials for soft roofing
Produced in Russia a large number of roofing materials. To carry out repairs or install new
roofs in winter Suitable materials with flexibility on timber with a diameter of 15 cm at a temperature of -25° C brands Technoelast, Uniflex, Linokrom, Bipolykrin, Bikrost, Krovlyelast and others.
The common thing is bitumen - polymer resin, applied to a base made of fiberglass, fiberglass or polyester.
Materials intended for fusing have a special film on the bottom that melts when heated - it serves as an adhesive.
Roofing materials without film are glued to bitumen-polymer mastics. Materials for the lower layers of the carpet are produced without mineral sprinkling; materials for the top layer have coarse or fine-grained sprinkling.
Major repairs and minor repairs - what's the difference? Difference between major repairs And minor repairs roofing is significant. To assess the condition roofing pie in several places, pits measuring 1x1 m are chosen, Based on the exposed areas, the number of layers of the carpet is determined
, type and condition of insulation, presence of vapor barrier. Major repairs involve replacement
, assessment of the condition of the insulation: if it is not in working condition, replacement of the insulation is required. If the insulation is in working condition, measures are taken to dry it.
NOTE! For minor repairs on defective areas of the roof, replace the carpet or lay additional layers waterproofing material. When performing repairs or installation by a contractor, each layer of roofing materials requires.
drawing up acts of hidden work Previously used slab insulation made of foam concrete and polystyrene are not able to meet the requirements of current standards for the resistance to heat transfer of enclosing structures and they are completely changed. Besides, current standards The requirements for vapor barrier of insulation have been tightened: previously, insulation from moisture vapor from residential and office premises was not required. Respectively,
To install a vapor barrier, it is necessary to dismantle the insulation.
Waterproofing and vapor barrier layers made of roofing felt, roofing felt, glassine, whose service life is no more than 5 years, definitely require replacement.
Common defects Defects most often arise due to technology violations performance of work, non-compliance design solutions
, carelessness of the staff and lack of care from the owner of the house. Regular roof inspection timely detection
swelling, vegetation, cracking and delamination of the material will be able to prevent leaks and wetting of the insulation.
The most effective method - filling the roof with water and draining the water after identifying the locations of defects - is possible on flat roofs and with special equipment.
- Leaks occur after precipitation or within 1-2 days later. There may be flickering leaks that appear periodically.
- Leaks of the first type indicate mechanical damage to the coating, improper installation or poor quality carpet material.
- Leaks of the second type appear due to poor-quality sealing of junctions and in case of incorrect installation of the fence and drainage system.
- Flickering leaks they talk about microcracks in the roofing material and insufficient size of aprons at the junctions.
Now let's talk about whether it is possible to lay soft tiles in winter?
Installation of soft roof in winter
Is it possible to install a soft roof in winter? Winter is not the best best time for roofing work. However, if necessary and following the rules, you can lay a soft roof in winter:
- Laying in winter should be done under a special awning;
- Working with solutions on water based conduct at a temperature not lower than +5° C;
- Thoroughly dry the base before applying mastics and primers;
- Soft roofing becomes very hard in winter and becomes brittle, so it should be thoroughly heated;
- Warm up the carpet material at room temperature before laying it within 1-2 days.
CAREFULLY!
Application gas burners for work on the roof it is allowed with non-combustible insulation(stone and basalt wool, fiberglass). When using insulation of flammability group G4 (expanded polystyrene), fusing should be carried out with a construction hair dryer!
The quality of roofing work in winter depends on compliance with the rules for working with materials. Soft roof installation at negative temperatures:
- The base must be smooth and dry;
- The screed for the slope must mature;
- Contact of porous insulation with wet materials and screeds is not allowed;
- Before fusing the waterproofing layer, surfaces (insulation, plastered parapets, ventilation shafts) must be primed with a primer;
- The junction areas must be protected with aprons.
Installation of roofing on a flat roof
Laying a soft roof in winter requires more technological operations : warming up the carpet material at room temperature, drying the base, heating the material before laying with a gas burner or hairdryer. As a result - additional waste of resources and money, low labor productivity. Subject to compliance technological maps according to the material manufacturer, laying soft tiles in winter is possible, but not economically feasible.
Temperature conditions and roofing work
In regulatory documents no direct ban holding in winter repair work on the roof. 
The main requirement for outdoor air temperature is written in SNiP 3.04.01 - 87 “Insulating and Finishing work»: roofing can be carried out in the temperature range from -30 to +60° C.
Work with flammable mastics is allowed down to -20° C.
Work with water-based compounds without antifreeze additives– not lower than +5° C.
The possibility of carrying out work largely depends on the technical characteristics of the material. If the passport indicates flexibility on a beam with a diameter of 15 cm at a temperature of -25 ° C, then at -30 it will break.
So, repairing a soft roof in winter at sub-zero temperatures in detail.
We repair soft roofs in winter
Urgent roof repairs can be done in winter two ways:
- Replace the defect patch from roofing material;
- Seal the leak with mastic based on polyurethane.
In the first case, the work is carried out as follows:
- We clear the leak area from snow and ice;
- Dry the leakage area with a gas burner or a hair dryer;
- The amount of roofing material required for embedding, preheated to room temperature, evenly heat with a hairdryer or burner from the bottom until the pattern changes;
- We apply the patch to the leak site, align it from the center to the edges, eliminating swelling;
- Glue by tapping with your hands or with a special roller.
Procedure for using mastic:
- Clean the leak area;
- Dry;
- We prime;
- We apply a layer of geotextile to the area to be repaired and secure it to the base with a stapler;
- Pour a layer of polyurethane mastic;
- After polymerization of the first layer (7-8 hours), we apply the second layer of mastic.
Preparation for repair
The first method is faster and easier, the second method is more reliable.
After renovation flat roof in winter it is advisable to leave there is a 5 cm layer of snow on it for protection from solar radiation and bad weather.
Roof care
If a problem or minor defect is noticed in time, it is easier, faster and cheaper to eliminate. In order not to bring the roof of the house to a state of repair, an inspection of the serviceability of the coating is necessary during the calendar year.
Is it necessary to clear snow from a soft roof? Yes, definitely!
In winter, it is necessary to clear the soft roof of snow: with a flat roof, heavy snowfall can exceed permissible load on the coating slabs - and this is a disaster! At pitched roof Excess snow will melt down in an avalanche. Cleaning soft roofs from snow is a mandatory procedure for roof care.
Is it possible to walk on a soft roof in winter? Urgently we do not recommend do this, since the coating becomes very fragile in winter and there is a high probability of damage to the coating.
This simple inspection will allow you to notice problems in time and make minor repairs.
- Upper floor ceilings - to detect stains;
- Roofs - to detect swelling;
- Roof junctions with parapets and at height differences;
- Fastening aprons and sealing seals.
At sub-zero temperatures pay attention to:
- Icicle formation;
- Ice plugs in funnels;
- Icing of sections of walls near drainage systems;
- The amount of snow on the soft roof.
Walking on a soft roof in winter is strongly not recommended!
In the fall, clean the roof and drainage system from fallen leaves. The topic of roof repair work is as broad as the number of roofing materials and technologies. If it is not possible to carry out repairs yourself, there is always the opportunity to turn to professionals. The roof of your house requires respect - the longevity of the building as a whole depends on its condition.

Soft tiles in Lately literally filled construction market. It's all because of the manufacturers of bitumen materials who tried to find a unique roof covering, and they achieved it. Laying soft tiles is carried out even in winter, but under certain conditions, and you will learn which conditions in this article.
Where did soft tiles come from?
Material like bitumen shingles certainly could not be produced in a country with low production oil. People first started talking about it in the mid-19th century in America. And even then it was used quite widely.
Of course, the coverage of that year was very different from the modern one. The main raw material was ordinary cardboard, which was coated with bitumen on both sides, after which it was attached to the roof. By the way, no one still knows the real inventor of this simple covering. Only in 1903 a patent for cut tiles appeared. Henry M. Reynolds, of the Grand Rapids Company, was the owner. The first samples of roofing material did not have good aesthetics, and the shape had only two types - rectangle and hexagon. As for the color, these were standard colors, which were set with natural sprinkles of gray and red shades.
The name “tile” for this product appeared only in Europe, and the old name “shingle” remained in the country of the inventor. Due to its positive qualities, this material quickly gained popularity wherever it appeared. This is confirmed by the villages and towns in various countries, in which you can always find a roof made of bitumen shingles.
As time passed, the structure of the product changed. At first it had clear and simple components - fiberglass and cardboard. By the way, fiberglass was used only in the sixties of the 20th century. As a result of this, some companies called their products organic shingles.
At that time, such roofing material was covered with only two types of bitumen - soft and hard. If the first one was used, then the body of the cardboard was completely impregnated, and when using solid materials, only its sides were coated. Despite the fact that a large amount of bitumen product was used, such a roofing coating did not meet many requirements, in particular waterproofing. Therefore, it was decided to use fiberglass.
Previously, they could not even imagine that gluing together several shingles could improve the quality of the product, and they thought so until the beginning of the 20th century, until the decision was made to laminate tiles in the 60s.
Around the same time, the topping also began to color, giving the material variety. color range. The attractive appearance gave the products competitive qualities, which only emerging manufacturers took advantage of. building materials. Over time, the appearance of the tiles began to imitate most known coatings, for example, wooden shingles, but at the same time had more best qualities. Among them are strength, stability, and service life. As a rule, such tiles serve reliable protection for 25 years.
But as you know, everything flows, everything changes, and today in some states of America you can find manufacturers who can give a lifetime guarantee on their product. Impressive, isn't it? By the way, the old base in the form of cardboard is gradually disappearing and can rarely be found in any tiles, except perhaps in roll material- roofing felt.
Installation of soft tiles in winter
In winter, the construction of houses, as a rule, freezes or proceeds very slowly. What to do if, before the construction of the house is completed, all that remains is to lay the roofing material, but it is used as a covering soft material. Is it possible to install it in cold weather? The answer is yes, but there are a lot of nuances here. So let's look at the most important ones.
Laying soft tiles in winter is carried out only if there are heat guns or special infrared heaters. Such units help to warm up not only the roofing material itself, but also the bedding under it. Thanks to the bedding layer on bitumen roofs maximum surface sealing is achieved.
In the summer, the air temperature allows you to do without heating devices, but even they will not save the material in severe frosts, so if outside the window low temperature, then it’s better to leave the idea of covering the roof until later suitable conditions, otherwise you risk getting a low-quality roof that will leak the next year.
So, the question “is it possible to lay soft tiles in winter?” deserves a mixed answer. At certain temperatures, for example, down to -5 o C this work can be done using heaters, but to achieve maximum quality, it would be best to wait until spring.
Finnish soft tiles
The phrase “soft roofing” immediately evokes an association with roofing felt, but construction has long presented us with better quality products. One of them is Finnish roofing. This type of roofing has an attractive appearance, practicality and ease of installation.
Composition of Finnish soft tiles
The Finnish company recently released a roofing covering that attracted the attention of literally the whole world. It looks like a piece element in the form of tiles, the edges of which have a figured ending. Standard sizes This material is 30-40 cm wide, 4-6 mm thick and 1 meter long.
All roofs with a slope of at least 11 degrees can be covered with soft tiles, which is probably one of the reasons for such a sharp popularity of Finnish material. But enough about popularity and size, let me tell you about its structure.
- Outer layer. On the outside, this roofing material is covered with basalt granules or other stone chips. This surface gives the material a kind of armor that prevents ultraviolet rays and mechanical damage cause damage to the coating
- Impregnation. It's no secret that soft roofing uses special modified impregnating mixtures that increase waterproofing properties material
- The main raw material is fiberglass, which, when compared with the cardboard used in roofing felt, is much stronger, therefore, the product itself is better.
- The bottom layer contains some quartz sand or silicon to prevent the tiles from sticking together during storage
The name “Finnish roofing” should not be taken as correct. This combination of words has become attached to the product only because this roofing material was produced in Finland. Today, many people produce such products, but the quality remains unchanged. Popular companies are Icopal, Tegola and Raflex.
Installation methods
Soft material means comfort when installation work, and when transporting it, you don’t have to worry about the integrity of the structure.
Thanks to innovations in construction industry, Finnish roofing has several methods of fastening.
- Self-adhesive method. The adhesive layer on some types of coating is a mixture of bitumen and rubber, which is protected by a film until the required moment. To fasten such a product on the plane of the slope, it is necessary to separate protective film, place it in the desired place and press the tile a little so that it sticks to the sheathing. The only obstacle to installing self-adhesive plates on the roof surface may be negative temperature. It will not allow gluing due to the hardening of the important layer
Structure of this material as follows:
- Basalt topping
- Oxidized bitumen
- Fiberglass layer
- Oxidized bitumen
- Adhesive mass with frost-resistant impurities
- Quartz or silicon sand
- Protective film
- Mechanical method. Here, fasteners are used as fasteners, and therefore this type It is somewhat cheaper compared to its self-adhesive counterpart. As a rule, ordinary roofing nails equipped with a wide head are used as fasteners. All fastening points must be covered by the sheet lying on top. This will create an airtight and reliable coating.
IMPORTANT: The lathing for this roofing must be done using a continuous method, and there should be no strong differences in height or sharp elements on its surface. For achievement ideal surface developers often use OSB boards rather than edged boards.
As a guide, I will list the main layers of a Finnish tile roof.
- Roofing material
- Lining layer
- OSB board, or continuous sheathing of boards
- Waterproofing layer
- Insulation boards
- Vapor barrier membrane layer
Positive and negative qualities of soft tiles
Not long ago, manufacturers of roofing materials received a new competitor - Finnish tiles. She quickly found her niche and became her main competitor. metal roofing and ondulin.
Why has this product received such high popularity in such a short time? It's all about her merits.
- Wear resistance. Finnish roofing outperforms the same roofing material many times over, because its service life is more than 70 years, while the latter’s lifespan is only a decade
- Resistance to temperature changes. This property delighted residents of the northern regions, where temperatures reach -50 o C. Temperature range of this coverage ranges from -60 o C to +150 o C
- Versatility. Soft tiles can be used on roofs with a slope greater than 11 degrees
- Economical. This property was discovered as a result of comparing waste metal tiles and Finnish roofing. At the same cost, the latter produces much less waste
- Easy to install. Due to its structure, installation can be done on your own
- Decorativeness. Manufacturers are trying to improve their product every year and are producing an ever-increasing assortment in terms of colors and types.
Despite such chic positive traits, this material still has disadvantages.
- Expensive. A product with a self-adhesive surface is quite impressive, and the simple appearance is also quite good
- There is no possibility of laying the covering on flat roofs
- High demands on the base surface
- Mandatory laying of the lining layer
Finnish roof good decision For country house . This coating will give your comfort a rather interesting and intricate look, and you will become a constant object of admiration from neighbors and guests.
