Roof Coatings What’s Important?
Owners and facilities managers of industrial or commercial premises have, for many decades, used coatings on damaged or leaking roofs as a cost-effective option to extend the roof life. It avoids the massive capital outlay of a completely new roof and has the added bonus, in our more environmentally aware society, that coatings can also add an insulating layer to the roof and so improve the energy-efficiency of the building. This can potentially reduce the heating and/or air-conditioning costs associated with running the building.
Industrial roof coatings are used for a variety of reasons in addition to extending the life of the roof. The right type of coating can not only repair cracks and leaks but can also reduce the amount of contraction and expansion due to temperature variations in the future. This can minimise the risk of future leaks and other damage. In the case of industrial metal roofing a coating can also halt any corrosion or prevent it from occurring in the first place.
As with all roofing extreme weather conditions and variations over a long period of time will reduce the effectiveness of the waterproofing and the insulation. The twin vagaries of our weather mean roofs are subjected to too much sunlight (which causes cracks to appear) and, conversely, too much rain (which will seep into the cracks and cause leaking). So the weather will eventually take its toll on every roof and the effectiveness and protection that it provides.
In the case of asbestos roofs there are serious safety issues and concerns that must be addressed. There are safety issues both for the roofing contractors as well as the employees working in the commercial premises. Any roof coating used on an asbestos roof must be able to bond any part of the asbestos roof that has become damaged and broken down into loose asbestos fibres and encapsulate those fibres to prevent them leaking into the surrounding environment.
Extending the life of an industrial asbestos roof with the use of a specialist coating is both a cost-effective and environmentally sound approach as it eliminates the need to remove the roof and transport it to an appropriate waste site and also eliminates the need to produce a new, replacement roof with all the energy and transportation costs associated with doing so.
From a more practical point of view, roof coatings also mean that the premises do not have to be closed down, which is usually necessary for a roof removal and complete replacement so this will have some additional cost benefit to the company.
So coating damaged or leaking industrial roofing (or even coating it as part of the regular maintenance) of any type, including asbestos roofs, is a safe, cost-effective and environmentally sound way to prolong the life of your roof when carried out by a professional roofing contractor using specialist roof coatings.
