Trapezoidal
This modern alternative to corrugated and has clean, crisp lines. There are trapezoidal profiles for both residential and commercial buildings and this is particularly suitable for low pitch roofs.


Tray Roofing
This contemporary style of roofing is often used as both roofing and cladding on architecturally designed homes. It is often referred to as Euroline or Euro-style roofing.

MEMBRANE ROOFING
We also specialise in membrane roofing, a solution perfect for flat roofs, roof decks and internal gutters. Membrane roofing is known for its exceptional waterproofing capabilities, making it an ideal choice for commercial buildings and homes in areas prone to heavy rainfall.
We offer solutions for new roofs, the removal, and reapplication of membranes, and the retrofit of new systems over existing membrane systems. We are supplied membrane from Sealco and The Rubber Roofing Company and install the following systems:
TPO
TPO membrane is a co-polymer of polypropylene and ethylene propylene rubber that has been formed into a membrane sheet and reinforced with a heavy-duty polyester scrim. It is a flexible rubberised material with the ability to be heat welded for permanent detailing.
EDPM (Commonly know as Butyl)
EPDM rubber membrane is used to provide waterproofing protection for a variety of roofing and exterior deck applications. A fully bonded rubber membrane is applied over concrete, steel, fibre cement boards, or construction plywood substrates.
TORCH ON
The torch-on membrane is a modified bitumen membrane system. Each layer of its double-layer system is torched on; the heat of which maximises the seal to the most intricate and vulnerable areas for leaks such as roof penetrations, internal corners, and gutter junctions.
