Waterproofing is one of the most critical aspects of roofing, especially in Malta, where sun, rain, and coastal humidity can quickly damage even the strongest structures. Property owners and contractors often ask: liquid applied roofing membrane vs rubber membrane – which one should I choose?
At Kibitec, we provide liquid membrane with best quality service and reliable results, ensuring that your roof remains fully protected, durable, and long-lasting. In this guide, we’ll break down the differences, highlight advantages, and offer expert tips for making the right choice.
Understanding Roofing Membranes| Liquid Applied Roofing Membrane vs Rubber Membrane
Before comparing, it’s essential to understand what a roofing membrane does. Simply put, a roofing membrane is a waterproof barrier applied to a roof surface to prevent water infiltration. Proper membrane installation protects the building’s structure, prevents leaks, reduces mold growth, and extends the lifespan of your roof.
Two popular options in Malta are liquid applied roofing membranes and rubber membranes. Each has unique characteristics, advantages, and applications.
What Is a Liquid Applied Roofing Membrane?| Liquid Applied Roofing Membrane vs Rubber Membrane
A liquid applied roofing membrane is a waterproofing layer applied in liquid form. Once it cures, it forms a seamless, elastic barrier that adapts to the roof’s surface.
Key Features of Liquid Applied Roofing Membranes:
Seamless Coverage – Forms a continuous layer without joints or seams, reducing weak points where water could penetrate.
Flexibility – Expands and contracts with temperature fluctuations and structural movement.
Durability – Lasts 10–15 years with proper application and maintenance, even in Malta’s harsh coastal climate.
Versatility – Suitable for flat, sloped, or complex roof surfaces, terraces, balconies, and even swimming pools.

What Is a Rubber Membrane?| Liquid Applied Roofing Membrane vs Rubber Membrane
Rubber membranes, often referred to as EPDM (ethylene propylene diene monomer) membranes, are synthetic rubber sheets applied over a roof surface. These membranes are highly elastic and known for their durability.
Key Features of Rubber Membranes:
Pre-Manufactured Sheets – Applied as large sheets with seams and joints that must be sealed.
Elasticity – Can stretch up to 300% without cracking, accommodating structural movement.
UV and Weather Resistance – Strong resistance to sun, rain, and temperature extremes.
Durability – Can last 20–30 years with proper installation and maintenance.
Rubber membranes are a popular choice for flat roofs but require careful seam sealing and precise installation to avoid leaks.
