What is “natural“ roofs?
“Natural“ roofs call roofs from the natural materials which were almost not exposed to processing: straw, cane, cespitose, slate roofs, roofs from a wooden shingle. If earlier similar roofing materials were everywhere widespread, then now they are exotic.
You want to have a garden on a roof? More precisely that your roof was a garden? Then you can suit to a cespitose roof - fashionable, eco-friendly, natural. Here only do not hope that thus it will turn out to save.
In former times the cespitose roof was the cheapest. To build such roof, only the rafter system and the earth was required. The poor who were not able to afford anything else had cespitose roofs mainly. Besides, such roof had one interesting plus - on it it was possible to graze pets. Of course, on a roof nobody started a cow, and here goats - happened.
Everywhere cespitose roofs were used at a construction of glaciers - cold cellars, medieval analogs of the refrigerator. Under a cespitose roof the constant temperature and as such cellars were quite deep remained, and temperature was low.
At strained circumstances cespitose roofs were never arranged over sheds, but - over granaries. Just that feature doing these roofs the best for glaciers (preservation of constant temperature) did them unsuitable for grain storage: under a cespitose roof grain is more subject to rotting, than under any other.
The present made cespitose roofs not just exotic, but exotic expensive. It is one of the most expensive types of roofs. The cespitose roof demands a powerful rafter design, a strong and dense board flooring, a qualitative waterproofing. And all this costs money, and rather big.
Besides, maintainability of a cespitose roof is extremely low, and leaving is required constant. On such roof everything grows - not only a garden or beds which part on envy to people around, but also any weeds. And if not to watch a cespitose roof, then through very short time the roof will become similar to the waste ground which grew with weeds. Very modest show.
The first thought of straw or cane roof - low cost. It is valid that difficult - went to the next field and took to nobody the necessary sheaf of straw. Or walked to a lake or a bog, cut off a cane. But actually everything is not so simple, and on straw and cane roofs to save presently at anybody it did not turn out.
In - the first, straw about fields or a cane from the next bog will not approach a reliable modern roof, in the natural form for the device, in any way. These natural materials need special processing: fire-retarding agents (against ignition), antiseptics (against various insects and mice). Nevertheless, despite processing, such roofs nevertheless remain fire-dangerous - to reduce probability of fast combustion (and the straw or cane roof burns, as gunpowder if not to take the appropriate measures), processing should be carried out regularly. And it already demands participation of experts that manages in a round sum. And installation of straw and cane roofs today - business not simple. It is not much experts - roofers work with similar materials. And who works, estimates such exotic work absolutely expensively.
The roof from a wooden shingle belongs to one of the most expensive types of a roofing covering. It is all about raw materials withdrawal: only 15% of volume are suitable for production of a shingle. Besides, as well as a vsluchaa with straw and a cane, the shingle demands special processing - anti-fire, anti-putrefactive, protection against various fungi and other biologically active organisms. Installation demands knowledge and is almost impossible without expert. Who, by the way, is not so simple for finding.
The slate roof is the most expensive option of a roofing covering today. Slate is very rare, is extracted it a little, and such material, of course, is very expensive. But if you have money and you want that your house though something reminded Louvre or the Tower, then you can arrange a slate roof.
And though the slate roof does not demand any special processing (a stone as it is clear, does not decay, it is not subject to infection with a fungus, does not burn), a large number of manual skills at production of roofing tiles and installation of a roof does the device of a similar roof not just expensive, but also problematic - to find the specialist in a straw roof much more simply, than on slate.
If properly to look narrowly at “natural“ roofs, then it will turn out that, natural only the slate roof - just stone plates processed only mechanically is rather natural. What cannot be told neither about a shingle, nor about straw, nor about a cane, nor even about the turf. All these types of a roof demand this or that processing, protection and so on. And still a question - whether they are really “natural“ and ecological after all that chemistry which is urged to protect from rotting, the fire, insects, fungi and so on.
However, they sufficiently exotic and quite are suitable for the status dwelling, a country house (a la a hunting lodge), baths, arbors and so on. Though the house which is under construction as “a family nest“, the estate of a la “Russian life of the XIX century“ you should not cover with either straw, or a shingle. It is like to wear sneakers with a three-piece suit from Armani or to a design evening dress to choose plastic costume jewelry.
