Large roof areas create high water volume
Metal deck factory roofs collect water over a wide surface. During Klang Valley storms, a single roof plane can push a large volume of water into one stainless steel box gutter. If the gutter slope, outlet size or downpipe path is weak, overflow can happen even when the gutter material itself is strong.
Cheong Seng checks whether water can exit the roof fast enough. The repair may involve joint repair, corner reinforcement, outlet clearing, downpipe alignment, flashing repair or roof edge waterproofing.
