Liquid-Applied Membrane

How Does a Liquid-Applied Roofing System Work?

Liquid-applied membranes are installed as a fluid, then cure into a continuous, rubber-like layer. Once cured, the membrane forms a monolithic barrier that fully adheres to the roof surface. There are no joints, fasteners, or overlaps where water can sneak through. This makes the system especially effective in stopping leaks and extending roof life.

These systems are typically applied with a roller, brush, or spray, depending on the roof’s size and complexity. Some systems are single-component and ready to use out of the bucket, while others are two-part formulas that cure chemically for extra resilience.

Thanks to their flexibility, liquid-applied membranes conform easily to tight corners and penetrations. This adaptability reduces waste and removes the need for metal flashings or pitch pans.

Is Liquid-Applied Roofing the Same as Roof Coatings?

While both are fluid-applied, roof coatings are usually used for cosmetic upgrades or light maintenance. They offer temporary protection and often require reapplication every few years.

Liquid-applied membrane systems, on the other hand, are engineered for full waterproofing performance. They meet higher durability standards, can be reinforced with fabric layers, and provide long-term protection in demanding environments. If you’re after more than a touch-up, a liquid-applied membrane is the way to go.

How Long Does It Take for a Liquid Membrane Roof To Cure?

Some fast-curing membranes can become waterproof within 30 minutes, while others may take a few hours. Most systems reach full strength within one to three days.

High humidity can speed up curing in moisture-triggered systems, while colder temperatures may slow things down. During application, our team follows strict guidelines for temperature, coverage, and curing to make sure your new membrane delivers maximum protection from day one.
