RE ROOFING OF FAILED ALUMINIUM FACED BITUMEN GUTTER LINING

This futuristic looking holiday home at Te Horo Beach, on the Kapiti Coast, was actually built 20 years ago, designed by Eisenhoffer.

The construction is of concrete block which is rendered with plaster and painted. The roof was rebuilt 4 years ago by fitting a new plywood substrate and coating with an acrylic/fibreglass membrane. During reconstruction the perimeter gutters were not rebuilt. Recently the gutters had shown signs of leaking and the existing aluminium faced bitumen sheet lining was bubbling and delaminating.

As the 29 metre long x 300mm wide x150mm deep gutters are used to collect rainwater for the homes' general water supply, the new lining had to be clean and safe and not give of any residues which would contaminate the water held in storage.

SPECIFICATION

Remove existing Aluminium faced bitumen sheet waterproofing from perimeter gutters.

Apply 3mm thick Index Elastocene  elastoplastomeric polymer-bitumen torchon waterproofing membrane to the base and 2 sides of the gutter sections, terminating at the top  inside edge on the outer side and at the top of the small drip batten at the edge of the sloping roofs.

Apply a acrylic/fibreglass bandage 100m wide at the top edge of the new membrane onto the sloping roof and to the top of the gutter sides on the outside.

Apply 2 coats of Hitchins Traffigard Top Coat in a light grey colour to finished gutter.
