When to Use Hot Melt Roofing

When installing or replacing a flat roof on your property, choosing the right method for waterproofing the deck is absolutely essential. One of the most effective techniques is hot melt roofing (also known in the trade as hot liquid roofing).

What is hot melt roofing?

Hot melt roofing is a waterproofing technique that creates a single, seamless rubber membrane that covers the entirety of your roof. Applied as a hot liquid, it adheres directly to your roof deck, ensuring a watertight seal that protects your property from the elements. Reinforcing material is laid over the initial membrane to provide structural integrity, with a second layer of hot liquid roofing applied over the top.

What are the benefits of hot melt roofing?

Hot melt roofing is long-lasting, typically coming with a warranty of 20–25 years. Since it is applied as a liquid, it forms a monolithic layer that encompasses the whole roof deck. This means there are no seams or lap joints that might become a potential weak point.

Hot melt roofing is ultra-durable and is not affected by standing water or dilute acids and fertilisers, making it ideal for green roof projects. Perhaps most importantly, it is quick and easy to install, making it a cost-effective solution.

When should you use hot melt roofing?

If you’re not sure when to use hot liquid roofing, these are some of the most popular roofing projects that utilise this waterproofing technique.

Uneven Roof Decks

Concrete, timber, and other deck materials can have surface irregularities. Hot-melt roofing adheres to all those imperfections, creating a waterproof bond directly with the deck and producing a smooth, level surface for your roof.

Green Roofs

Hot liquid roofing is ideal for green roofs. Not only is it durable and long-lasting, but it is also formulated to be resistant to diluted acids and fertilisers that are often used in green roof projects.

Fast-track Flat Roofing

If you’re operating on a tight timescale, hot melt roofing is an excellent choice. Its ease of application and fast curing times allow for quick installation without skimping on quality.

Not all flat roofs are simple, rectangular decks. Some are oddly shaped to match the building; some have a complex network of drops, while others incorporate skylights, ceiling vents, HVAC equipment, and other protrusions. Hot melt roofing seeps into all those nooks and crannies, allowing for easy application.

How much does hot melt roofing cost?

Several factors can affect the cost of your hot liquid roofing project, such as the size and complexity of the roof. Similarly, if you’re laying down hot melt roofing as the foundation for a green roof or some other utility roof solution, you’ll need to take the cost of that additional work into consideration.
