All Seasons Roofing & Waterproofing were given a brief to replace an old IBR roof with an internal gutter problem.
The customer was a major Cape Town Hotel and being a Cape Town building this roof carried water from the main roofs into an internal gutter. In addition, the gutter carried the water from the IBR roof itself.
At times the customer reported that the gutter would overflow due to the volumes of water that was passing through it.
All Seasons Roofing & Waterproofing proposed an increase in the gutter size to give the roof the ability to carry more water. In the process we would replace the roof sheets with new IBR profile colourbond roof sheets from Blue Scope Steel.
To raise the level of the roof the old roof sheets were carefully removed and carried off site. The existing SA Pine purlins were removed. All Seasons Roofing & Waterproofing then supplied and fitted new SA Pine roof trusses to raise the roof level. We then replaced the roof purlins and raised the gutter using plywood.
The new IBR profile roof sheets were added with the required flashings, polybuttons & Closers fitted to the headwall. These flashings were waterproofed using heat fused membrane, with this we then painted using a silver bitumen paint. This protects the waterproofing from the harsh sunlight.
The gutter was then waterproofed using a 4mm heat fused membrane. All Seasons Roofing & Waterproofing extended this waterproofing onto the roof sheets to give the gutter more depth.
To ensure that water was directed into the main gutter we made sure we supplied 110mm down pipes to make sure that water was directed and controlled over the IBR roof and into the newly installed and waterproofed gutter.
