All About Thermal Splitting

The common problem with fiberglass-based shingles is that they are prone to splitting, which could cause a serious structural problem on your roof. In these cases it is important to take action as soon as possible. Depending on the damage, after all, you can simply ask a contractor to conduct a roof replacement. But why do these splits happen? Home Pro Exteriors, Inc. discusses thermal splitting.

What is Thermal Splitting?

It is basically the expansion and contraction of fiberglass-based materials, which includes the shingles on your roof. When they expand and contract rapidly due to shifts in temperature, the material might warp and eventually split apart.

Causes:

Thermal Cycling

Thermal cycling is one of the factors that could lead to tearing. The fiberglass may have become brittle after exposure to extreme conditions. The continuous cycle from extreme heat to extreme cold may cause thermal contraction and thermal expansion, which can affect both roofing and siding materials

Adhesion

Another point of consideration is if the shingle adhesive cured into a bond that is too tight. This would make the shingle less resistant to wind, which could result in tears developing when the shingles are exposed to high winds. A combination of these two causes can also cause thermal splitting even with moderate thermal cycling patterns throughout the seasons.

Repair Options

If you or a trusted contractor like Home Pro Exteriors, Inc. encounter these thermal splits during an inspection, you will need to determine which portions of the roof are compromised by thermal cycling and set things right immediately.

Once identified, you can consider which roof repair alternative to go with. You can opt to re-roof over the undamaged shingles in order to add an extra layer of protection. On the other hand, if the damage is fairly extensive, then a roof replacement might be in order.
