In this post, we will explore the benefits of liquid applied and sheet applied roofing membranes and provide guidance on how to choose the right option for your building.

Liquid applied roofing membranes are a popular choice for commercial and industrial buildings due to their ability to easily conform to complex roof designs and provide a seamless waterproof barrier. They are also easy to apply, even over existing roofing material, which can save time and money during the installation process by avoiding often expensive and time-consuming removal costs.  Being able to overlay existing roofing systems also helps minimise the impact to activity within the building.

Sheet applied roofing membranes are made from sheets of synthetic material that are installed on the roof in a mechanically fixed or fully adhered method. Being supplied preformed makes them a good choice for covering large, uncomplicated roofs quickly. They are also relatively easy to install, which can save on labour costs.

When choosing between liquid applied and sheet applied roofing membranes, it is important to consider the specific needs of your building. Liquid applied roofing membranes are ideal for complex roof designs and for applications where a seamless waterproof barrier is required. Sheet applied roofing membranes are a better choice for large, less complicated roofs. Sika has BRANZ-appraised roofing solutions in both the liquid applied and sheet applied categories, so you can rest assured the quality and durability is second to none.  Adding to this peace-of-mind is our nationwide network of Sika Approved Contractors who are trained and certified in the installation of these specialized products.

If you are unsure which option is best for your building, it is always a good idea to consult with a Sika roofing expert. They can assess your roof and recommend the best roofing membrane for your specific project, as well as suggest a range of Sika Approved Roofing Contractors to do the install.

In summary, liquid applied and sheet applied roofing membranes both have their own unique benefits and can be suitable for different types of buildings and roofing applications. By considering the specific needs of your building and consulting with a professional, you can make an informed decision and choose the right roofing membrane for your project.
