Waterproofing The Join On A Dual-Pitch Roof

The join between the upper and lower slopes of a dual-pitch roof can be a problem area for leakage and corrosion if designed inadequately. These joins are common on colonial style homes and on extensions, where a metal skillion roof is added to an existing tiled roof.


Where both roof sections are metal, many tradesmen simply fix the top sheets as tightly as possible against the bottom sheets (Figure 1). However, this type of join is prone to leakage because of insufficient overlap or "back distance". On a shallow roof, the back distance needs to be at least 250mm.


Rainwater travels faster down the steeper upper slope than on the flatter lower slope. At the join, rainwater depth is increased because of the dam effect of faster water mergi.....
