From Shingles to Rubber

How many different kinds of roofs can you spot on the houses on your street? A few decades ago, you may have only seen shingle roofs, perhaps with the occasional slate roof mixed in. But these days, there are more kinds of roofing on the market. Metal roofs are becoming common because they can be made from recycled materials. Tile is a popular choice because it lasts a lot longer than other roofing materials. And then there are some roofers who install rubber roofs because they're smooth and easy to install. Learn more about roofs of all types on this blog.

Why It's More Difficult To Maintain An Asphalt Roof In A Hot Climate

If you live in a hot climate and have asphalt shingles on your roof, you might wonder how the heat affects them and what you can do to protect them. Asphalt shingles, especially organic ones, are not the best option for hot climates. 

Why are Asphalt Shingles Bad for Hot Climates?

Asphalt shingles are made of a base material covered with asphalt and granules. The asphalt acts as a waterproofing agent, and the granules provide color and UV protection. However, asphalt also absorbs heat and transfers it to the underlying roof deck and the attic. This can increase the temperature inside your home and make your cooling system work harder, resulting in higher energy bills and more greenhouse gas emissions.

Asphalt Shingles Deteriorate Quickly?

Additionally, asphalt shingles can deteriorate faster in hot climates due to thermal expansion and contraction. When the temperature changes, the shingles expand and contract, causing them to curl, crack, or lose granules. This can expose the base material to water damage, mold growth, or fire hazards. Moreover, asphalt shingles can lose their elasticity and become brittle over time, making them more prone to breaking or blowing off in high winds or storms.

Can the Shingles be Protected?

If you have asphalt shingles on your roof and you live in a hot climate, there are some things you can do to extend their lifespan and performance. Here are some tips:

  • Install proper ventilation in your attic to reduce the heat buildup and moisture accumulation under your roof
  • Apply an excellent roof coating to your shingles to lower their surface temperature and increase their reflectivity
  • Look at your roof every once in a while for warning signs of damage, such as curling, cracking, blistering, or granule loss
  • Contact a roofer if you have lost any shingles

Also, hire a professional roofing contractor to perform routine maintenance and repairs on your roof. They can advise whether to replace your roof entirely or switch to more heat-resistant roofing material.

With proper care and attention, you can make asphalt shingles last longer and perform better even in the hottest climates if you prefer this type of roofing material. However, if you want a more durable, energy-efficient, and environmentally friendly roofing option, you might want to consider metal roofing, tile roofing, or solar roofing. These alternatives can withstand high temperatures better than asphalt shingles and offer other benefits, such as lower maintenance costs, higher resale value, and lower carbon footprint.
