Current Treatment of Box Gutters (maintenance)

Existing box gutters (also known as concealed gutters) are bound with roofs above them and walls on their sides, and often require manual tampering in order to fit them in their location. During this process, the conventional 'C' shaped boxed gutter is likely to lose its original shape and not funnel stormwater effectively. Often roofs are required to be disassembled in order to allow the new box gutter to be placed in its final position, an operation that requires much time and cost. The scenario can get more complex when hazardous roofing materials such as asbestos are in place and special measures are required to be taken hence incurring greater costs. In industrial roofing applications 'C' shaped box gutters are often wide and long and would require several hands to convey thus increasing costs.  Read more about Box Gutters details..
