Age: Over time, ridge capping may naturally deteriorate due to the effects of aging, such as exposure to the elements and UV rays from the sun.
Weather conditions: Extreme weather conditions, such as heavy rain, snow, and wind, can cause ridge capping to crack. Constant exposure to these elements can weaken the material and cause it to crack over time.
Poor installation of ridge caps above: Ridge capping that is not installed properly can lead to stress points that can cause cracking. This can occur if the capping is not secured properly, or if the wrong adhesive is used during installation.
Movement of the roof structure: If the entire roof structure moves or shifts due to settling or other factors, it can cause stress on the ridge capping, leading to cracking.
Thermal expansion and contraction: Changes in temperature can cause the ridge capping to expand and contract, which can lead to cracking if the material is not able to withstand the stress.
