What is a common method for installing metal roofing?

The method of overlapping and securing with screws or clips is widely practiced in the installation of metal roofing due to its effectiveness in ensuring a watertight seal and structural integrity. This approach allows each panel to overlap the next, creating a barrier against water infiltration. The use of screws or clips to fasten the panels to the roofing structure provides necessary stability and allows for expansion and contraction, which accommodates temperature changes.

Additionally, securing panels in this manner minimizes the risk of wind uplift, as the fasteners are strategically placed to maintain a firm grip on the roofing material. This installation technique is also favored for its speed and efficiency, making it a preferred choice among roofing professionals.

In contrast, adhesive sheets, tar membranes, and concrete pouring are methods that are not typically associated with metal roofing. Adhesive sheets may be more applicable for other materials, tar membranes usually suit flat roofs, and pouring concrete could lead to unnecessary weight and complications in drainage for metal panels.
