The roof coating is made of copper foil, coated with a hardener and sprayed onto the roof to provide a stronger coat.
But what if your roof is cracked, or there is a hole in the roof that needs to be patched?
This can be very expensive and is where it’s worth a second look.
Roughly two per cent of all roofing projects are repaired, according to the roofing consultancy RMS Roofing, with more than half of all repair costs paid to contractors.
In the first half of 2017, the average cost of repairs to a roof was £17,000, according the firm.
If repairs are required on a project that has already cost £100,000 or more, then the roof coat can cost upwards of £60,000.
“In the past it was easy to find a cheap roof coat that could be replaced and it was also easy to see where to look for better options,” said Richard McKeown, director of RMS.
“Now the industry is focused on cost efficiency and finding ways to save money on roof repairs, so we are finding more ways to improve the roof coating to offer greater protection to the building.
In the latest edition of RRS’ ‘Rise and Shine’, the company surveyed the top 50 roof coaters in the country, offering an insight into what is currently the industry standard.
While there are a number of coatings, they tend to be cheaper and less expensive to use, according RRS.
There are a couple of different types of roof coat, which can be bought separately or in packs.
The standard coat will not be the same on every roof, with the coatings that are commonly used on the top of a building being the best choices.
The coatings most commonly used are: Cadet Coating: A copper-coated sheet that has been cured in a furnace or heat exchanger, it will make a coat that is waterproof and strong.
Safer Coating : A thin, flexible sheet that can be applied over a flat surface and is usually applied to roofs with a slight roll or bump in the surface to increase the surface resistance.
Laser Coatings : A combination of a paint, wax and an iron oxide.
Cleaning and Maintenance : This is the cleaning process which involves removing any dirt or grime.
It can take anywhere from 15 minutes to an hour and can involve using a brush, spray bottle or a roller to remove the coating from the roof.
Hardening: This is the process of hardening the roof, making it tougher, which is a common method of cleaning and maintenance.
Paint: Used in a paint job to add colour and make the surface more attractive.
Wood: An alternative to coatings to coat the surface of the roof or other areas.
Coatings and Roofs: These are materials used to make a roof coat which can also be applied to other surfaces.
Wax: Wash the surface with water to remove any dirt and grime, or rub it in to coat a roof with a soft shine.
Eco-coating: Efficient roof coat.
Plastic coatings: More expensive but often used to add a gloss to a coat, and make it more resistant to weather.
Flat roof coating: The process of coating the roof with insulation to improve insulation properties and protect against rain and hail.
Boiler coatings Bolts of paint and a brush are used to coat and waterproof the surface.
These coatings are typically applied on the sides of the building, which will improve insulation characteristics, making them a good option for roofs that are under heavy loads.
