Well forgotten old, or the construction of the roof of substandard materials

Modern construction market offers a variety of materials, which can be covered by a roof, ranging from slate and ending with standing seam, slate roof and genuine, flexible or composite tiles. In spite of the huge selection, many novice developers think about the question of whether you can return to experience of their ancestors and to use the materials on the roof with a long history - straw, reeds or wood. In this case, homeowners care how practical will these materials, as they will serve, and whether it will lead to a significant increase in the desire to construction cost estimates.

Leave outside the this article topic of green building, ie, houses that were built from natural materials, and are approaching the matter from a purely technical and practical point of view. You will learn:

• The different cane and reed roof.
• What features should I look for when erecting the roof of reeds.
• How to ensure the fire safety of a thatched roof.
• What is the cost to make the roof of reeds.

Features a thatched roof

Straw and reeds - is construction materials, widespread in the past. If you walk through the old villages in the south of Russia, we can see the huts with roofs covered with slabs, straw or reeds and rushes.

It is also known to all adobe and adobe houses, the walls of which are made from a mixture of clays, Sand and straw. Although the technology their ancestors today are experiencing a rebirth, cottages erected from natural materials - a rarity. Developers scare away the complexity associated with the search for high-quality materials (straw, reeds), their high cost and the lack of skilled labor. All this leads to an increase in the construction budget. Only one thing - to roll up their sleeves, to study the technology to get the right materials and build your dream home.

Before you start this, you should soberly assess their strength and capabilities, as such construction may fly into a lot of money. This article has described the "pitfalls" construction of houses made of natural materials. Now consider, as it is often called - reed roof. We think that this house will not leave anyone indifferent.

It affects the unusual and special aesthetics inherent in such buildings. Recognized masters in the construction of reed roofs are considered to be Dutch. They have accumulated extensive experience and technology to perfection. At the same time in our country, in view of the low prevalence, many misconceptions about walking cane roofs. The first - called a thatched roof, but speak correctly on the roof that was built from reeds.

This is due to the confusion in naming various species of plants and conventional, "national" cattail and reed title - "reeds". In fact, there are three types of plants. To understand, we give them the photos.

Cane

The roof of reeds, unlike cane, doing much less.

The second factor limiting the development of reed roofs in our country - the fear of homeowners that the roof will be short-lived and fire.

Bolkonskaya (Participant FORUMHOUSE):

House with a roof, of course, looks amazing, but I think it is better to use only on small architectural forms - arbours, etc. Put a roof on a house or a bath, I would not dare. I'm afraid of fire. It is also interesting, such as a roof behaves in Siberia, at 30 degrees below zero. Oh, and also the high cost of stops, especially when compared to other roofing materials.

Indeed, our harsh climatic conditions - cold, long winter, frequent rains and transitions through 0, can lead to accelerated destruction of the organic material. But, unlike the straw, which is more prone to corruption, correctly executed reed roofs can last decades.

Thatched roof is more suited to the southern latitudes, as it is less durable and more capricious in operation, especially when exposed to adverse weather conditions. So leave it outside the scope of this article, the more that the process of building a roof of straw and reed is almost the same.

Fear that ekokrovlya quickly burn in any emergency situation (for example, it gets released someone squib) and mainly refers to the thatched roof. Light a reed roof is more complicated. When exposed to an open flame source cane char, but the flame does not extend.

Far more dangerous - fast possibility of flame propagation into the under-roof space ventilation during the so-called open design of a thatched roof. More details we will talk about this later.

The third factor - the high cost. Practice shows that the construction of thatched roofs is several times more expensive than usual to all materials, such as leather or shingles. It affects a large amount of manual (very expensive) work requiring highly skilled workers, as well as difficulties with the purchase of high quality material.

You can not go to the next construction market or in a store and buy high-quality bundles of reeds. The material will have to be ordered in firms that can be counted on the fingers + shipping from the regions. The result - a significant increase in the budget.

The nuances of building a thatched roof

By the reed as roofing, should be treated the same as a conventional building materials. Should not impart its mythical characteristics or deliberately understate properties.

Of paramount importance, according to the rules, first house project put. Abroad widespread principle: architecture, construction and design of the cottage are adjusted under a thatched roof, and not vice versa! It is a mistake to think that the first house is built, and once erected truss system, the developer, that (suddenly) visited the idea to get a thatched roof (if funds are available) can be safely make it.

Such an approach will lead to unpredictable results in the long term. Up to a significant reduction in the life of the roof covering and the subsequent expensive overhaul or a complete dismantling of the roof of reeds.

The most important characteristic that affects the life of a thatched roof - a roof pitch. The higher it is, the longer the roof before its renovation. For example, it is believed that when the angle of inclination of the roof in 25 degrees roof will last no more than 15 years. If the angle is 45 to 50 degrees, the life of a thatched roof is increased from 25 to 50 years.

In any case, the upper part of a thatched roof is saturated with moisture. This would increase the coating mass, and therefore - to increase the strength requirements truss system, the bearing capacity of foundation walls and underground.

Also popular opinion that the layer of the reed in 30-40 cm thick is sufficient, and the roof does not require additional heat insulation.

But because energy costs are rising, that an increasing number of developers are thinking how to cut heating costs. For the construction of energy-efficient cottage with a thatched roof is required to erect a closed loop thermal insulation and extra insulated mezhdustropilnoe or podstropilnoe space. In addition, you must provide a reliable vapor barrier inside the premises loop because moisture (if negligible vapor barrier) contained in the pair, once in the lower layer thatched roof, it will lead to accelerated rot.

It describes, than good attic with insulation differs from the cold atticAnd that it is better to choose for a country house.

Providing a thatched roof fire safety

We have already dealt with the issue of fire safety thatched roof. If the reed is placed on a wooden crate, and between the rafters and the coating is left ventilation gap, the case of fire, due to natural draft, it is virtually impossible to repay.

The use of all kinds of fire impregnation thatched roof, as well as to protect against rot does not bring long-term results, as over time means washed precipitation (rain, snow). In addition, high-quality impregnation thatched roof is complicated and expensive. In addition to a large expenditure of antiseptic and fire-fighting equipment, the application of the principle to popular we "sprinkle a little here and there from a garden sprayer" does not work.

Abroad, most of the roofs of the cane is not processed by special means, and such roofs stand for decades, though, and require regular maintenance.

To minimize the risk of fire, use a different type of mounting a thatched roof - closed design.

This method is technically resembles stages of laying shingles. On the roof mounted rigid and flat base (from waterproof plywood or OSB) with a thickness of 18 mm. Then a layer of waterproofing fit - it then stacked sheaves reed fixed on the basis of screws, to which is attached stainless wire.

installation process is similar to the binding of the reinforcement cage using a crochet hook. Wire "clips" firmly hold the cane on the roof, it does not blow off the wind, as well as the inside (due to lack of air ducts) to the coating no oxygen is substantially reduced probability scale fire.

Also for the house with a thatched roof is difficult to find ready-made solutions for wastewater from the roof - hoppers, chutes, etc. Standard solutions available on the market, does not fit into the design of the house. Exit - to increase the overhang of the roof and to organize the so-called natural (disorganized) with drainage water flow with a thatched roof in a storm drain or trough of manufacture homemade tree.

Add to all the above, that the reed roof eventually fade, but a natural yellow color becomes gray shades.

It is also important to orient the house to the cardinal points, as when exposed to sunlight southern and northern side of the roof will fade with varying intensity. These are just some of the difficulties associated with the device thatched roof.

Costs for the construction of thatched roofs

The high price of a roof of reeds - a factor which is able to cool the ardor of any developer. But, as practice shows Forumhouse, members of our portal does not give in to any difficulties and are always ready to develop new technologies. In connection with this interesting experience with the user's nick taneko, who decided to cover a small grill house roof of reeds. We tell about this building cost.

taneko (Participant FORUMHOUSE):

In one bundle of reeds in Moscow asking for 150 rubles. The most difficult thing - to calculate how many sheaves required per 1 sq. meter roofing layer with a thickness of 250-300 mm. I decided to learn it and got different answers. Masters say - from 8 to 12 pieces. So I took the averaged value - 10 pcs. Hence, only the material for 1 square. m roofs will require 1500 rubles. And it is - not including the cost of the work!

Add that taneko I chose a closed structure for stacking the reed in order to reduce the risk of fire. Then followed a long search for high-quality material suppliers.

taneko:

In Moscow engaged in the implementation of reeds a few firms. 4 found. It turned out that the price of 150 rubles per sheaf - deception. It cost to call as on the other end say that the cost of 300 rubles, or delivery to Moscow will cost 25-30 thousand. rub.

The search continued. I managed to find two companies that sell sheaf 120 rubles, but ask for the delivery of 25-30 thousand. rub. Finally found a supplier who sells bundles of 110 rubles., And have a warehouse in the Moscow region.

Total: 400 wearer bought a sheaf of 110 rubles. 1 pcs. = 44 thousand. rub. Delivery cost $ 7 thousand. rub.

Besides reed, for the construction of the roof a total area of ​​40 sq. mthe user's required:

• Galvanized wire diameter of 5 mm - 150 m (25 kg) to 180 kg per 1 RUB.
• Stainless steel wire diameter of 0.8-1 mm - 250 m (1.5 kg) at a price 1100 rub. per 1 kg.

The high price of the wire due to the fact that the usual soft, which is used for knitted reinforcement is not necessary. As a result, it was necessary to buy expensive welding "stainless steel".

Of the tools needed:

• Cordless grass shears with a nozzle for cutting of bushes.

• Crochet hook wire 400-600 rubles.

• A long screwdriver bits to 250-300 mm.
• Screws 2 cm long with a flat cap.
• Homemade blade for tamping sheaves.

What eventually happened, clearly demonstrate the following photos.

Interesting economic feasibility of these works. Whether or not to make a reed roof on their own? At prices in 2016 (assuming averaged) installation cost of 1 sq. m thatched roof "in the company" costs 1500 rubles. or more, excluding the cost of material. If you take the price for a full cycle, including all the work, the price of 'reed' roof rises to 5,000 rubles. 1Q. m (with material). The roof of the complex forms will cost even more expensive! This is more than the cost of construction of the roof of the materials considered to be elite (natural ceramic tiles and wooden roof).

taneko:

I can say that 1500 rubles. 1Q. m - a "promotional" price that is announced if a cane is placed on a perfectly flat surface, without calculating device complex elements - ridge corners, ends, chimney penetrations etc. I calculated the cost of our roof mounting 3 Moscow firms. Total went from 325 to 400 thousand. rub. with the material. T. e. I eventually save at least 265 thousand. rub., as the roof made 2 weeks of slow work at your pleasure. If my roof will last ten years, I'm just happy.

Stages of construction of plank roof

If the roof of reeds - an expensive pleasure, the roof covered with wood, for example, with boards - a more affordable option. Here's what happened in the portal user with the nickname Izbushechnik.

Izbushechnik (Member FORUMHOUSE):

The erection of the roof took 12 cubic meters. m selective board 25h150h6000 mm (better to take 30h180-200h6000 mm). Boards are stacked in two layers. Whittling them himself. You also need to choose a cutter grooves - grooves to a depth of 5-7 mm, departing from the edge of the board about 5 mm. The impregnated everything colorless antiseptic impregnated and coated with varnish board. Boards nailed on small nails and a length of 6-7 cm, beating them in the center part (not trough) 2 pcs. 4-5 local board. Boards rallied without fanaticism. The top boards overlap the lower joint.

Despite the seeming simplicity of the work performed, there are some nuances to be aware of in advance. The main thing - to calculate everything and make sure that the board warpage when bowing in the right direction.

Rule of thumb: if you look at the end of the saw cut of the board, the visible growth rings and their direction (arc) clear where the center of the barrel, and its external part. Board dries bends away from the center of the tree, ie, the outside of the barrel.

When warping board is bent in the form of the letter U, we by wooden boards on a "chute up - down the chute." Because nails are hammered in the middle, the boards have some mobility in the sediments.

Izbushechnik:

Boards are held as if suspended and may be "free" to dry and soak. The second batch of milled boards, not as the first, and vice versa - the direction toward the center axis of a tree that dries her clenched down. The bulk of the rainwater flowing down over the upper board downwards. Grooves cut off the excess from getting on the front row. What leaked therebetween, tesinam flows along the second row, and the grooves do not allow water to flow past. It turned out that the lower row - "dish", upper row - "cover."

We add that tesiny to transverse planks nailed - "crate" (150h50 mm), laid flat, and the user is laid on rafters waterproofing layer. As a result, the roof space available for blown air ducts. Boards dry and do not rot. If through tesiny leak water, it falls on the waterproofing, and the board in the natural oscillation of moisture swell, merge and converge as riveting to a tub.

At the user's words, wooden roof turned out beautiful and "alive". In summer it rassyhaetsya to form wide gaps between the boards, razmokaet winter and interlock board. But do not forget that such a roof requires care, because winter has to clean off the snow, which does not come with it himself.

Izbushechnik:

I am satisfied with what happened, and I think that the other roof on the Russian hut just do not look.

We add that the roof more than 10 years, as the photos below dismantled as hewn roof looked like in 2014.

The result is impressive!

Summarizing

The roof, made of natural, organic materials - is primarily variant intended for fans of such a coating. Cane or wood roofs suitable for those developers who do not, or are on a budget, or are willing, perceiving all the nuances, to do everything with your hands, efficiently and conscientiously. Only in this way we can guarantee an excellent result, and for many years to enjoy an unusual and spectacular roof made of substandard materials!
