The most important circumstance in the choice of roofing material is the bearing capacity of the building and its rafters. If a solid stone structure can withstand roofing from almost any material, then for a wooden house many options may be impossible or undesirable. The shape of the roof is also of great importance, if it is simple, then the easiest way is to cover it with a large-sheet roof (slate, galvanized rolls). At the same time, it will be more convenient to cover a roof with a complex shape with small-piece materials (tiles, shingles, reeds) or flexible, easily cut metal sheets.
Despite even the best roof, the house still needs layers of heat and waterproofing materials laid under it. They save internal structures from condensation, leaks, temperature changes and other influences, from which it is almost impossible to protect yourself with the help of a roof alone.
WHICH ROOF IS BETTER?
Metal roofs are almost ideal for roofing. They have many advantages: strength, long service life, low weight, plasticity, a variety of available types. The disadvantages of metal roofing materials include a lot of noise that is created during rain, and an increased risk of lightning strikes. Also, metal plates can interfere with mobile communications.
A standard wave-shaped metal tile is an excellent choice for a home with a simple roof shape, such as a gable roof.
Rolled steel is suitable for protecting roofs of any shape, including those with long gentle slopes. The fact is that due to the seam connection of individual sheets, rolled steel forms a roof that is almost completely impervious to water. Polymer-coated sheets are more reliable, but ordinary rolled steel for painting also provides good protection.
NON-FERROUS METALS: COPPER, ZINC-TITANIUM, ALUMINUM
Non-ferrous metal roofing differs from standard galvanized sheets in significantly greater durability. Materials such as copper, zinc, aluminum, as well as various alloys based on them with the addition of other metals, are very resistant to corrosion. Therefore, the estimated service life of such a roof can exceed two centuries.
The bituminous tile is made from the fiberglass impregnated with bitumen. The result is a lightweight, flexible waterproof coating. Thanks to these qualities, shingles can be used on roofs of various types. However, due to the lack of rigidity, such a roof needs a continuous, frequent crate.
Ceramic tiles are one of the oldest roofing materials. It has many advantages – strength, durability, practicality. Of the shortcomings, first of all, it is worth noting the large weight and unsuitability for operation in areas with a cold climate. The material does not tolerate periodic temperature fluctuations above and below zero. Satisfactory resistance to weather changes has tiles with low porosity. Also acceptable strength in cold climates is different shingles, made mainly of cement. On average, its service life exceeds 30 years.
Slate is a combination of materials of both natural and artificial origin. Natural slate is made from slate – a layered stone. Factory roofing is made from cement, asbestos and other additives. This material is resistant to frost, temperature extremes, long service life, strength and affordable price.
Reeds have been used for roofing since ancient times. This water plant is naturally resistant to water and rot. Therefore, the reed roof perfectly withstands even prolonged precipitation. Also, the reed has excellent thermal insulation properties. The material has only two serious drawbacks – a relatively short service life and easy flammability, so it is not recommended to use it in houses with stove heating.
Shingles – small plates of waterproof wood, such as aspen. Roofing from shingles is absolutely environmentally friendly, like reed. Its main disadvantage is the high cost of the material and its installation. However, such a roof looks just fantastic.
Inverted roofing is a specific roofing technology that is commonly used for buildings with large flat roofs. The main feature of such a roof is the overlapping of the waterproofing layer with heat-insulating materials. Thanks to this, the waterproofing is protected from temperature extremes and other adverse environmental influences, which prolongs its service life.
For thermal insulation, durable waterproof and frost-resistant polystyrene foam boards are usually used. To create the slope necessary for water drainage, they are laid at an angle of 2-3%.
Earth has long been a traditional roofing material for ordinary dwellings. In our time, it is in demand, as it allows you to break a continuous green coating of flowers and lawn on the roof. Under the ground, there must be a reliable waterproofing material.
