How a Liquid Applied Roofing Membrane Can Prevent Exterior Water Damage

A leaking roof can be an expensive and lengthy repair process. Or it used to be. 

Liquid roofing membranes have become increasingly popular over the last decade. You can now improve the lifespan of your roof and repair it by using this method. Compared to traditional roofing materials, it is now cheaper and faster to do repairs. 

Sounds like a win-win, right?

But what exactly is a liquid membrane, and how does it work? If you are looking for an alternative roofing repair solution, keep reading and we will answer some of your questions.


What Is a Liquid Roofing Membrane?

Consisting of one or two components, a liquid roofing membrane is a resin that is applied to reinforcement materials. It is applied using rollers, squeegees, or a spray bottle, and once cured becomes a seamless UV and water-resistant coating. An aesthetically pleasing material, liquid membrane comes in various colours to match all roofs.

Roof Membranes vs Roof Coatings

Often when speaking about roofing repairs, the terms membrane and coating are used interchangeably. But there are a few key differences when it comes to the two products, even though they are similar.

Liquid Coating

A liquid coating forms a moderate protective layer when applied to the surface of the roof. Liquid coatings have no protection against water, with no warranty from the manufacturer against water damage. If water pools in an area, the coating will often flake and leave the underlying waterproofing exposed.

Liquid Membrane

A liquid-applied membrane is a waterproofing system that has a much thicker application than the coating and forms a durable and protective barrier on a roof. It is covered by the manufacturers against water damage.

Benefits of a Roofing Membrane

When it comes to benefits, a liquid-applied roofing membrane is a winner. Some of the benefits you can enjoy are:

  • Lightweight protection against environmental conditions without adding weight to the structure
  • Correctly applied roofing membrane forms a tough and flexible waterproof barrier
  • It is a cost-effective way to extend the lifespan of roofs in good condition due to its reliability and durability

The application of a liquid membrane is also a safer and quicker installation than other roofing options. If you choose a product such as bitumen, it must be heated to high temperatures before it becomes liquid. The heating creates an unpleasant smell, as well as the risk of kettle fires and burns.

While it is a trusted and effective way to waterproof, the modified version of this uses a roofing torch, which carries the risk of building fires. So, all in all, the liquid membrane is a far safer option for you and the company using it, with no heat needed and very little unpleasant odour.

Choose a Liquid-Applied Roofing Membrane

If you are struggling with a leaking roof or just want to lengthen the lifespan of your roof, a liquid roofing membrane is the way to go. It offers fewer risks and more rewards than other roofing repair methods because of its quick and safe application.
