It should come as no surprise that your roof plays a vital role in protecting you and your home from the elements. Wind, rain, snow, your roof offers valuable protection from all sorts of harsh weather conditions. One you may not really think about though is heat. Your roof keeps the harsh UV rays of the sun from scorching your entire home, but after countless years of doing this, the effects of the heat can take a serious toll on your roof. But what kind of problems can the heat cause to your roof and what can you do to prevent your roof from heat damage? We’ll answer those questions and more here.

The Negative Effects of Heat and Warning Signs of Heat Damage

It may seem like heat wouldn’t really cause that much damage to your roof, but the truth is long exposure to extreme heat can be just as bad for your roof as ice or storms. Prolonged exposure to harsh heat can cause serious damage to your shingles. The heat of the summer sun can cause asphalt shingles to crack and potentially fall apart. In really extreme temperatures shingles can even melt. Metal roofs aren’t safe from the heat either. Extended exposure to intense heat can cause metal roofs to begin deteriorating. Since intense heats can cause so much havoc for your roof it is very important to constantly be aware of the condition of your roof to ensure it isn’t exhibiting any signs of heat damage. Some of the common warning signs that your roof may be suffering from heat damage includes:

  • Cracked shingles
  • Roof tiles shrinking or blistering
  • Discoloration of roof tiles
  • Missing shingles
  • Mold
  • Etc.

It is essential to be on the lookout for any of these signs of heat damage, especially during summer, to help ensure your roof stays in the best condition possible. If you notice any signs that your roof is suffering from heat damage, contact someone who can help resolve these issues immediately.

How to Prevent Heat Damage

                At the end of the day, if your roof isn’t shaded, then it is basically impossible for your roof to avoid the intense UV rays of the sun, but that doesn’t mean you can’t strengthen your roof to give it protection from the unavoidable heat. You can apply roof coating to your home which more or less functions like sunblock for your roof. It strengthens your roof to help keep it safe from UV rays. Periodic acrylic coatings can also help to prevent the damage caused by thermal shock. Replacing shingles can also help lessen the blow of extreme heat. Changing the asphalt shingles to a cooler material like tile or swapping out dark shingles for lighter colored ones can help prevent damage caused by heat. There are countless other solutions to the problems caused by heat, but these are some of the most common and popular.
