Will Heat Actually Cause Your Roofing Shingles to Expand?

Like any item, roofing shingles can expand when subjected to heat and contract when kept in a cold environment. Depending on the speed of the temperature drop (or increase) as well as its intensity, it’s possible for certain materials to be distorted beyond their ability to return to their initial form.

Such is the case with asphalt shingles. As you probably already know from driving on older roads, asphalt can crack and split as a result of contracting and expanding due to temperature changes in the winter and spring. Thermal expansion causes these changes in the tarmac you drive on, and it can also cause the same thing to happen in lower quality, affordable asphalt shingles.

To avoid this phenomenon, it might be a good idea to either choose a composite shingle roof that uses asphalt as just one of the ingredients to make it more resilient, or you can select a more expensive ceramic tile or concrete roofing shingle that will last longer and present less of a risk to be damaged by thermal expansion when the weather gets hot.

It’s also a good idea to consider metal roofing. Some types of metals are more resilient in the face of temperature changes, and their flexibility allows them to contract and expand without splitting or remaining in a dented shape.

Your best option is to meet with a respected roofing contractor in Houston TX and discuss what roofing system will work best for your home or business.
