How long does elastomeric roof coating last?

Protecting a roof and keeping it looking good for long periods is important to landlords and building owners. A roof is an investment, as is the building, and a solid robust coating is critical to provide protection and maintain the building's value.

Maintaining a roof to keep it free from corrosion and the weather elements is equally important, and one consideration that is often overlooked is the flexibility of the paint coating used. Typically the roofing substrates are made from flexible components such as aluminium frame and wood, and these will move. It is therefore critical to have a roof coating that not only protects the roof but also has some stretch in it to ensure it keeps protecting your roof for years to come.

So how long should a flexible roof coating last?

Quite often we see elastomeric roof coatings that oxidise from the salt laden sea air and UV from the sun. Commercial grade elastomeric roof paint applied by a professional roofing contractor typically lasts well — however 80% of failures are due to poor installation, and this will impact on the time the coating lasts for.
