The materials used to waterproof a roof are rubberized asphalt, polyurethane liquid membrane, and EPDM rubber. Let’s take a closer look at each. What are their benefits and drawbacks? Read on to learn about the benefits and drawbacks of a combo roof waterproofing system. The material used for roof waterproofing is also affected by the climate. If the materials used for roof waterproofing are incompatible, you may want to look for new roofing material.
Hot rubberized asphalt is a waterproofing membrane with no seams and is aesthetically pleasing. Hot rubberized asphalt is a complex process, and it requires special safety precautions. Working with hot materials is dangerous, so be careful not to overheat the material or apply it to damp or contaminated surfaces. Hot rubberized asphalt is a common choice for roof waterproofing, but you should still follow safety precautions when applying it.
Polyurethane liquid membrane:
Whether waterproofing a flat roof or a sloping roof, polyurethane liquid membrane is an effective solution. Its seamless finish is resistant to weathering and UV rays and offers a long-lasting, water-tight seal. This liquid membrane is easy to apply and durable, lasting decades in most cases. Unlike tar and gravel roofs, polyurethane liquid membranes don’t cause joints, so installing without specialist equipment is easy.
EPDM (ethylene-propylene-diene-monomer) rubber is an excellent option for roof waterproofing. This synthetic material comprises single-bond molecular structures and offers good resistance to oxidation and UV degradation. It is resistant to high and low temperatures and is used extensively in various applications, including HVAC systems, radiator hoses, and roofing membranes. Despite its durability, EPDM can be easily corroded.
EPDM rubber is a versatile material that can withstand extreme temperatures and has a life expectancy of 50 years. Because it is an elastic material, EPDM can be used for roof waterproofing on low-sloped or flat surfaces. It is an excellent choice for roof waterproofing in many different applications, including garages, extensions, and dormer roofs. The elasticity of EPDM rubber makes it an ideal material for all of these areas, as well as on the main roof.
