Case Study  : Asbestos Slates
This property in Somerset was having major problems with the roof
due to leaking and cracked Asbestos slates, cement missing from 
the ridges and valleys, and the worst aspect of this was the fact that
moss and lichen had eroded the surface and was allowing dangerous
asbestos fibres to  " Fly " in the air .around the house.
Our clients had several  quotations to remove the Asbestos and re roof
the property but the cost was beyond them. The cost alone to remove
the Asbestos slate by a licenced contractor would have cost almost the
same as retiling due to the Health and Safety implications..
The property owners decided to use  our encapsulant system that is
guaranteed for 15 years. and gives old roofs a new life.

Our Polyurea roof coatings are designed to last 30 -50 years depending on the environment. The system enables us to install thermal insulation if required by the client without disturbing the inside of the building. 

Sprayed into place using the latest spray hot spray technology, the coating dries  within 10 seconds and can be walked on almost straight away.

The Polurea coating can be applied to almost any type of roof including complicated roof geometries . This roof below is on a church in London and had so many leaks 
due to the difficulty in weatherproofing the various materials that made up the roof construction, felt, asphalt, cement render, asbestos, and slate. Our coating system completely covered all areas creating a one piece structure with no joins or seams.
