4 Solutions of Flat Roof Systems For Your Home

Today flat roof is really popular due to its reliability and relatively economical installation. For those, who want to make such type of roofing construction, should remember that there are different flat roof systems. Each of these systems has its own interesting features and advantages. So let’s take a look at them in detail.

Flat Roof Advantages

Before the installation of roof system, you should learn some information about each type, compare them. Maybe, this will help you to decide, what option to choose. In general, flat roof benefits are the following:

  • high reliability;
  • durability;
  • water resistance;
  • simple installation;
  • high fire resistance;
  • easy maintenance.

Thus, installation of flat roof is perfect option for your home. Flat roof systems have a lot of different advantages, which will be suitable for you.

Types of Flat Roof Systems

There are different types of flat roof systems, among them:

  • rolled roofing;
  • mastic roofing;
  • membrane roof (EPDM, TPO, PVC);
  • metal roofing.

Rolled roof

This roofing is made from bitumen-polymer or bitumen with special reinforcing layer (cardboard, synthetic or membrane). The most widespread rolled roofing materials are glassine and ruberoid. But they have some disadvantages, like low frost resistance, high probability of rotting occurrence and fragility.

Bitumen rolled roofing materials is based on polyester or fiberglass. The addition of polymer modifiers makes this material more heat and frost resistance. Also they reduce the probability of cracks occurrence.

During the installation of rolled roofing, this material must be welded on the concrete or metal roof basis. Also you can stick this material to the basis, using mastic.

Mastic roofing

Mastic roofing is a kind of polymer membrane, which is formed directly on the roof surface. Actually this type of roofing must be installed by putting the oligomeric products on the concrete roof basis. In a result, this material forms a continuous flexible membrane on the roof surface.

Therefore, this is a liquid roof – it is a composition, which must be poured on the roof surface. After the hardening, it becomes monolithic rubber-like material. This material will be very good solution for districts with harsh climate.

Mastic roofing has light weight, elasticity, high durability, high resistance to ultraviolet radiation, oxidation, corrosion. Also it is able to withstand temperature fluctuations in the range of -40 °С and +100 °С.

Membrane roofing

This modern roofing material offers very simple installation. Its mounting technology allows to reach the creation of solid (seamless) coverage. For building with strong reliable (for example, concrete) basis membrane roofing will be the most suitable option. Membrane roofing materials include such types:

  • EPDMmembranes;
  • TPO;
  • PVC.

The main advantage of this roofing material is fast installation. This option is really convenient, if you need to cover the roof with a huge area. Folded membranes can be delivered to the roof very quickly. And then you just have to deploy it on the roof and seal joints with the use of special tape.

In addition you can install this roofing material on the old covering. Also, finishing the installation, you can put above the roof covering special pillow of gravel or concrete slabs. Properly installed covering can serve about 30 years.

Metal roofing

Another one good option for flat roof is metal roofing. As the metal roofing you can use roofing iron (sheet steel), galvanized iron, corrugated metal and metal tile. Each of these materials can serve about 30 years. But the most reliable and durable material is galvanized iron.

Also you should consider the weight of metal roofing. It can be quite heavy, but some types can be relatively light. For example, the weight of galvanized iron reaches about 20 kg (with crate). Weight of corrugated metal can lay in the range of 11-15 kg. And the easiest material in this range is metal tile – 4.5 kg.
