Flat roofs are a distinct part of modern architecture design and act as an aesthetically appropriate frame for a modern or contemporary style building or home.
When planning a flat roof build or renovation, it is important to consider specific flat roof waterproofing provisions.
Here is our guide to flat roof waterproofing from the waterproofing experts.
When planning flat roof waterproofing, some factors we consider include:
In Australia, we tend to use cement or different types of metal for flat roofs. These need to sit at a 1 degree angle to allow for water runoff. The industry offers a variety of flat roof membrane brands, and each project is unique and requires detailed analysis.
The waterproofing membrane needs to be durable, robust and flexible to withstand the climatic and usage conditions. When choosing flat roof waterproofing, our team would generally look for a membrane with UV and heat-reflective properties.
Waterproofing membrane can be water-based, solvent-based (elastomeric), torch-on bitumen or elastomeric sheet, which is either PVC, TPO, Butynol or rubber. Using waterproofing technology to analyse the area, the selection of materials used in the area will depend on the specifications of the building.
When developing our comprehensive solution design, we would consider the following:
Sheet membranes can be the most costly type of membrane but can have a lifespan of up to 50 years.
