Protecting your roof from the heat

Living in the UK, we’re used to the familiar warnings of protecting our roofs against water damage. It’s rare that sun damage is an issue for us Brits, but with this summer’s surprise heatwave showing no signs of abating anytime soon, your roof could be in danger of serious damage.

Why do I need to protect my roof from the heat?

While it may not seem like it, the sun is a major contributing factor to roof damage. Over time, the UV rays and heat can degrade your roof’s materials which can cause the buckling of asphalt shingles if the roof is unvented. This can also cause damage to the wood underneath and when it finally does rain, it also leaves your home vulnerable to water damage.

As the temperature rises, this also means that your roof will start to expand and contract. This can cause the underlying tar paper of a tile roof to dry out, causing it to become brittle and cracked. Again, this means that your roof can’t offer as much protection from rain damage as it should.

How can I protect my roof in the heat?

While there isn’t much we can do about the weather, there are many things you can do to protect your roof while it’s scorching hot outside.

    • Seal your roof

If it isn’t already, make sure that your roof has been sealed and coated. This will protect it against the harmful UV rays which can cause long-term damage. By preserving the material, you’re creating a durable environment which can withstand the heat for a longer period of time. The type of sealant you use will depend on the material your roof is made from but typically, professionals recommend using an asphalt-based sealant.
 
 

  • Change the material of your roof

If your roof is in need of some serious TLC or you’ve been thinking about replacing it for a while, consider using a cooler, more reflective material like tile or PVC. This will lessen the heat that’s absorbed by your roof, which will keep it in better working order for much longer.

  • Look for signs of sun damage

If you roof has already been compromised, you may notice the following issues:

  • If you have shingles, they may be cracked, curled or missing. This is a clear sign of drying and damage
  • If you have a clay tile roof, look for cracked or crumbling tiles. If this has happened, it means that the sun has depleted them of their natural oils and they will need to be replaced
  • Cracks in sealants around flashing for chimneys and vent piping is another sign of sun damage
    • Have regular inspections

Regardless of the weather conditions, having your roof inspected is a good idea. Regular inspections will help identify future problems which could be incredibly costly to fix if they’re left to get worse. A professional will be able to tell you if weather damage is already present, how it can be fixed and how you can prevent these issues from occurring in the first place.
