Asbestos Roof Repair

What to do about old asbestos sheets? Which asbestos roof repair method is best? You can’t leave it there if it’s leaking but the cost of removing and replacing asbestos safely can be eye watering. That’s where asbestos encapsulation comes in…


Widespread use of asbestos in the 60’s has left many property owners with a problem today. The old materials have started to fail and have been damaged in many cases. Due to its now well documented health risks, removing and/or replacing old asbestos boards needs can be a very costly undertaking. It requires specialist handling, extensive PPE and dedicated disposal units. All of these things come with a considerable price tag.

Asbestos Encapsulation with the Hyperdesmo Polyurethane Liquid Waterproofing System

That’s where encapsulating the asbestos with Hyperdesmo comes in. It is a far quicker and easier method of renovating old asbestos. You don’t have to worry about hiring a specialist skip to safely dispose of the materials.

Asbestos roof repair by encapsulation with Hyperdesmo has a number of benefits


  • It makes the material waterproof again. Any areas where the asbestos has failed will be sealed again when you coat it like this. Although bigger cracks and joints can be prepared with a polyurethane sealant, smaller cracks may be harder to see. Encapsulating the asbestos like this seals those micro cracks, solving the problem.


  • It makes the material safer. The health hazards of asbestos are well documented but Hyperdesmo encapsulates the material, trapping the dangerous fibres in the process


  • It is considerably cheaper than replacing the old asbestos. Being able to repair rather than remove the material can save a significant amount of money because of the expense associated with safely handling and removing it. You’d have to hire a specialist skip to dispose of the materials on site which would also include the cost of disposing the materials.


  • It is faster than replacing the old sheets. You apply the Hyperdesmo system and that’s it!

Hyperdesmo in Action

We recently quoted for materials for an old asbestos barn in West Wales. You can see a video review of the works below and you can read more about the project here

It was in a really sorry state and was one step away from being demolished. However, when the owner priced it up, the cost of the asbestos encapsulation method with Hyperdesmo was around a third of the cost (65% cheaper!) compared to removing and replacing it!

This is a massive saving and has left him with a building that is waterproof, secure and useable again. It even looks much better! There’s also the option to offer it on wide range of jobs  now that Hyperdesmo has been BBA approved!
