Expanded metal can be placed over the edge of the roof as a protective layer to provide extra strength and stability, and it can also help keep out moisture and other elements that could penetrate the roof structure.
The use of expanded metal for roof flashing offers several advantages. Firstly, it enables an even distribution of tensile and load forces over the entire roof surface, reducing the risk of damage and failure. Secondly, it offers increased flexibility, allowing the roof to adapt to different weather conditions without being damaged by overstretching or deformation. Thirdly, it allows for easier installation and maintenance, as the expanded metal can be quickly and easily moved into place.
Overall, expanded metal is used in roof flashing to improve the stability and safety of roofs and ensure long-term performance. It is an important element in the construction of roof systems and helps to minimize damage and failures.
