What can be used instead of bitumen to save?

When a flat roof covered with bitumen leaks, you should think about repairing it. And if you use bitumen - not a very suitable option, you need to save, you can use roofing material. This material is a loose cardboard, which is only impregnated with bitumen. Therefore, it costs less than the first option for finishing a flat roof.

Work sequence

However, you need to understand that roofing material is not very reliable and not very durable material. It will last 2-3 seasons, after which it can swell, burst. It will have to be partially repaired or completely replaced. That is, saving in this case is a necessary measure, which is used in emergency cases.

So, before laying the roofing material, you need to try to carry out a major overhaul of the flat roof. Therefore, all previous materials are removed from the surface. if there are cracks and chips in the concrete, they must also be repaired using a special concrete mortar.

Also, gaps from all adjacencies to ventilation shafts, to other structural elements that are installed on a flat roof are necessarily removed. After you can use roofing material, which is laid by the deposition method. That is, the rolled material is rolled out, it is simultaneously heated by an open fire from a special lamp.

Bituminous mastic for waterproofing

To save on partial repair of a flat and pitched roof, you can use bitumen mastic. This material is known to be cheaper than bitumen itself. Today you can buy mastic, which is designed for cold use. It can also be used for waterproofing and for gluing roofing felt. The material is convenient during operation, it is not so expensive, it is in a liquid state and it does not need additional heating.

You can also use hot mastic, which must be heated so that it dissolves and covers the surface. However, you need to choose the simplest and cheapest option to save. Bituminous mastic, which has additives in the form of polymers, strength additives, is prohibitively expensive. You need to follow this moment so that you can save money and do not have to overpay.

Also, to save money, you can use tar - a material that represents the residue formed after oil refining. This is a black resinous mass, which is inexpensive, but also requires heating to process and cover the roof.
