5 Great Benefits Of Heat Barrier Roof Coatings

A roof directly exposed to the elements experiences continual cyclic thermal movement as the roof material heats up and cools down during the day. Not only does this movement occur between night and day cycles, but also as a result of passing clouds, wind, rain and condensation. Here is a list of 5 great advantages to applying a heat barrier roof coating to your roof:

  1. Extended Roof Life

Of course! Roof coatings create a resilient barrier between the elements and your roof (be it metal, tiled, concrete, shingles). The right roof coating increases your roof’s waterproof quality guarding your roof from harmful sun rays, prevents UV damage, and reflects heat away from the roof’s surface. This increases the longevity of your roof while lowering roof maintenance expenses.

  1. Reduced Cooling Costs

Heat barrier roof coatings lower roof’s surface temperature and decrease your home’s interior temperature by an average of 8 – 12 degrees Celsius! This happens in two distinct ways:

  • A reflective roof coating when applied to roofs help reflect more sunlight from the surface reducing the amount of heat absorbed by the structure, which then translates into reduced energy cost.
  • Quality roof coatings will also reflect damaging ultraviolet and infrared sunlight away from your building (this is called thermal emittance), allowing for cooler roof and building temperatures.
  1. Fade Resistance

Reflective roof coatings help your roof maintain its colour over time improving the overall look of your roof as it ages. Since the roof coatings are reflective, the colour of the roof is maintained for a longer duration, which makes your roof look more appealing, as per the images below:


  1. Lower Maintenance

Lower thermal expansion of the roof means less movement of fasteners, joins, overlaps and structural elements. The result is extended maintenance intervals and longer life of the roof components.

  1. Can Be Applied On Any Roof Type:

Roof coatings are formulated to adhere to a wide range of roofing types; metal roofs, asphalt roofs, composite roofs, galvanized metal roofs, wooden roofs, tiled roofs, concrete roofs and others.
