All you need to know about Silicone roof coatings

Silicone roof coatings (rubber roof paint) are the most popular roofing membranes in New Zealand, here we will spell out a few reasons why, and also tell you all you need to know about them.

Silicone roof coatings are easy to apply & maintain

Silicone roof coatings are the easiest & fastest roof coatings to apply, they can either be sprayed or rolled on over the top of the existing roof surface, compatible roofing surfaces can include butynol, torch on, decramastic & long run iron but include many more. This ease of application has two key benefits to you:

  • Faster installation, this means the labour & installation costs are lower as it can be applied in a shorter time frame than other roof re-lay or repair options. This decreases the cost to you.
  • No waste disposal fees, as the silicone membrane is applied over the existing roof surface the amount of waste product to be disposed is significantly reduces, this effectively eliminates disposal costs of the old roof surface as its simply ‘painted over’

"Silicone roof coatings can be about 50% more cost effective than a conventional tear up & re-lay"

Silicone roof coatings can be maintained for an indefinite lifetime

Silicone membranes are not only easy to apply the first time, but when the coating comes to the end of its life or in need of repair again, It can simply be cleaned & re-coated to provide another 10-15 years protection! So in short, silicone membrane coatings can be maintained indefinitely at a fraction of the cost of conventional roofing systems.

Silicone roof coatings are extremely durable

The Kemseal silicone roofing membrane system has a elongation factor of +/- 200% which ensures it can withstand building movement (earthquakes etc), sudden temperature changes, hailstorms & oxidation.

Silicone membranes also have the highest UV resistance rating all roofing membranes available. Where other membrane coatings are used successfully in the northern hemisphere it does not necessarily mean they will succeed in the New Zealand UV environment where the UV index is higher both in Summer, Spring & Autumn when compared to similar latitudes of the Northern Hemisphere. Therefore, the Kemseal silicone-based membrane coating system is what Stratacote sell throughout New Zealand.

After application in liquid form the silicone membrane cures to form a highly water-resistant surface that can withstand water ponding for indefinite periods of time. This is especially important as no water or moisture will transmit through the membrane.

How silicone roof coatings can help you become more energy efficient

Silicone coatings are available for sale at Stratacote in either white or grey. We all know that darker roof’s absorb more heat than lighter ones, so when the white Kemseal silicone membrane is applied as a final coat the thermal intake of a building can be significantly reduced, in some cases energy consumption is reduced by as much as 35%, this is especially so where the existing roof coating was black as most solid roof membranes are, a final coating of Kemseal white can reflect the suns rays to provide a roof that helps you become more thermally efficient!
