There are three basic¬†combo roof waterproofing¬†methods: liquid, bituminous, and polyurethane. We’ll discuss each of these in turn. For more information, read on! But first, let’s talk about what waterproofing means. Which one is best for you? Find out how they work and how they can benefit your building! Also, read up on EPDM rubber, Polyurethane liquid membrane, and more!

Liquid waterproofing:

Liquid roof waterproofing can be used for several different applications. It is perfect for refurbishing flat roofs and bridge cracks and strengthening highly trafficked walkways. These products are fast-drying and can be applied over a range of substrates. Some types of liquid roof waterproofing are suitable for inverted roofs, which require the installation of ballast on top. Cold-applied liquid waterproofing is ideal for flat and pitched roofs with pitches up to 15 degrees.

EPDM rubber:

When applying an EPDM roofing patch, clean the area well and allow it to relax. While bubbles will not cause your roof to fail, they will detract from the appearance of the building. If you notice that bubbles or blisters are developing on the seams or affecting the membrane’s quality, you may want to call a roofing specialist for assistance. Here are some common mistakes that people make when installing EPDM roofing.

Polyurethane liquid membrane:

One of the most common roof waterproofing methods is polyurethane liquid membrane. This waterproofing material is very flexible and can conform to the shape of the roof. It also maintains its superior performance in a wide range of climatic conditions. It is often used in flat roofs but requires a proper application. Despite its low cost, this waterproofing membrane can crack or peel after a certain period.

Bituminous membrane:

The first step in bituminous membrane roof waterproofing is preparing the substrate properly. It is necessary to clean it thoroughly, as blemishes and grease can prevent the waterproof membrane from adhering properly. The next step is to apply a primer to the surface, improving adhesion and preventing bituminous oils from leaking through. Once the surface is properly cleaned and dry, the craftsperson can apply the waterproofing membrane. A blowtorch may be used to speed up the process.
