Built to Last, Sealed to Safeguard
Obsidian Roofing specialises in hot melt roofing, a reliable option for waterproofing flat roofs with lasting durability. As seasoned hot melt roofing contractors, we implement heated bitumen directly onto the prepared structural deck, forming a smooth, fully bonded membrane. This liquid layer moulds to each detail, bonding with materials such as shingles or slate to craft a robust moisture-resistant barrier. Its self-healing properties mean lesser repairs and remarkable longevity.

FAQ’s​
What types of projects is hot melt roofing ideal for?
Hot melt roofing is a perfect option for new builds such as office buildings, domestic blocks, tower structures, podium decks, and even green or blue roofs. At Obsidian Roofing, we typically apply this system over concrete substrates, yet timber decks may also be suitable, provided the surface is adequately prepared and level.
When is hot melt roofing not the appropriate fit?
This system is not appropriate for projects where the structure cannot bear the weight of an inverted roof. Since ballast needs to weigh at least 80kg per square metre, weak or unsupported decks are a no-go. It is also not suitable for metal surfaces unless timber is added, or in places where the use of hot boilers raises safety concerns.
What kind of maintenance does a hot melt roof need?
Like any flat roof, a hot melt system requires regular inspection twice a year. Our crew suggests clearing any debris and ensuring gutters or outlets are tidy to keep everything working as it should. With minimum effort, you can relish dependable waterproofing for years.
How long can a hot melt roofing system last?
With adept installation and basic maintenance, hot melt roofs are designed to go the long haul, mostly lasting multiple decades.
