The important information about the basic types of roofing materials
On what parameters to choose a roofing material
- Loads on a roof. Besides specifications of deposits, it is necessary to consider a body weight of a covering and a roof (with all rafter system), as well as wind loads. Therefore it is necessary to learn the maximal parameters of specifications and weight of all roof to start to choose a roofing material.
- Durability of the future roof. Here fire resistance enters. Here the main thing is to not spend many money for too abrupt material for not too abrupt structure (for example, a shed or technical facility). And for the house, certainly, to stint a covering it is not necessary. Otherwise avaricious will pay second time for repair.
- The architectural decision on the taste. It depends on the material (the form, a structure, color). But not any roofing will easily lay down on your roof. For the some people types of roofing materials there are norms (for example, percent of a bias) on which application of a material is admissible or inadmissible at a covering of a roof.
Manufacturers establish warranty periods for a roofing at a compliance with rules of transportation, installation and operation. But many materials can serve much longer a warranty period.
The given type of a roofing represents the formed clay weight after roasting. As a result color of a tile becomes red-brown (How to install clay roof tiles). The size of such plates small (12×12 inches), and weight of everyone about 4,5 pounds. The ceramic tile happens: ordinary, flat tape, grooving tape, grooving stamped, 1-wave and 2-wave. Standard fastening of such tile is applied within the limits of a bias from 22 up to 60 degrees. If above additional fastenings and if below - establish qualitative ventilation and a waterproofing are necessary.
It is an alternative version to the previous type of a roofing which on a type anything from it does not differ. It happens convex and flat. The working bias varies from 20 up to 60 degrees. Huge plus is that such type of roof material in the course of time only types strength and does not lose the properties.
Bitumen tile cover with fiber glass, cellulose, polyester and a special paint. Owing to a bitumen rubber layer, the tile perfectly docks with adjacent sheets, creating an excellent waterproofing. Also it has good plasticity owing to what it can be bent hands somehow (especially it is useful at complex roofing). The choice of a bias amazes: from 12 degrees up to a maximum.
We have decided to deduce a metal tile under a separate subtitle as it is very widely widespread and popular among any roofs. It represents the leaf of the zinced steel covered by polymer. Owing to the invoice, from afar it seems, that it will consist of separate parts, but actually it is the whole leaf in 0,06 inches, which sizes great variety (depending on the sizes of each part of a roof, sheets can be cut off depending on necessary length). Approaches for any biases, beginning from 15 degrees. But up to 20 degrees it is desirable to improve hermetic sealing of joints.
The given material is made of the hot zinced steel which is then goffered for increase of rigidity. It is the most simple type of a covering roof. Such material is applied on any bias, beginning from 10 degrees and finishing the maximal size. As well as slate, profiled sheeting is used for a roofing of economic facilities, sheds and so on.
Steel folded roof
Steel folded roof are sheets of smooth steel. The comprehensible bias for the given roofing material begins from 20 degrees up to a maximum. Technology of installation following: sheets fasten with each other by means of gearing with an adjacent leaf. The turned out seam between sheets refers to a fold. The given type of a roofing covering can be seen on churches, old manors and industrial buildings.
Roofing from natural materials
Such types of roofing materials are applied mainly on commercial buildings with objective of attraction attention of clients. For example, it can be restaurants, hotels, bars and constructions similar to them. As a material straw, a cane, a tree is applied.
Seam roofing on the basis of copper and aluminum
This material is durable, nice and, as the consequence, dear roofing material. But it is justified. Copper remains plastic even at negative temperature. Besides, in due course under influence of vapors of carbonic gas and atmospheric precipitation copper becomes covered by a brown-green membrane which protects a material from corrosion, mechanical damages and ultraviolet. Aluminium too becomes covered by a protective film membrane.
