When it comes to roof insulation, the question of which waterproofing membranes should be used is an important one. EPDM rubber and bitumen are two of the most recommended materials for roofs. Bitumen is a good waterproofing material by its nature, as it is easy to apply, inexpensive, and has excellent adhesive properties. Bitumen-based liquid membrane and bitumen-based roll membrane materials are the best-known, economical and high-performance materials used for roof insulation.
Putty is the best option for waterproofing flat roofs, as well as for roofs with a minimum angle of inclination. Its half-life is not less than 20 years and it adapts perfectly to concrete, wood and metal. Despite the fact that dozens of waterproofing agents have been released on the market in recent years, bitumen is still one of the most popular base materials for waterproofing roofs. However, bitumen paint can be brittle at low temperatures and soft at high temperatures, both of which are critical to Johannesburg's climate.
Before deciding which roofing waterproofing material to choose for insulation, it is necessary to take into account the amount of precipitation and the weather conditions of the area where the building is located. To perfectly complete the waterproofing of the roof, it is necessary to use bitumen-based waterproofing membranes, as well as beveled tapes for corner leaks, drainage systems to prevent water accumulation, coating materials to protect the upper layer and various cement-based waterproofing materials to waterproof concrete. Water insulation of roofs is a protection process that is designed to be applied to the roofs of buildings, using impermeable materials. The quality of the roof waterproofing influences its insulation, safety and operation of the entire roof.
Waterproofing membranes based on liquid bitumen are materials that are generally applied as a primer and also provide waterproofing on the applied surface. This is the easiest and most affordable way to waterproof roofs that is used for pitched roofs: slate, pile or metal roofs. Bitumen is not only suitable for flat roofs, but also for waterproofing basements and underground structures. The concrete must be waterproofed with waterproofing products for roofs, the coating must be applied, the edges of the coating must be chamfered, drainage systems must be installed to prevent the formation of pools of water and the process must be finished with a suitable paint or coating material as the top layer.
While bitumen is considered to be the most durable material for roof waterproofing, it may not be the best choice for extremely cold climates. Roof waterproofing materials prevent possible leaks and act as a barrier between the building, rain and snow.
