Take care of your roof and your roof will take care of your property

A traditional flat roof just isn't built to last, unlike our range of outstanding flat roofs. Our flat roofs are fitted with guarantees of either 15, 20 or 25 years, which are insurance-backed for total peace of mind, and have life expectancies of up to 50+ years.

We are manufacturer-approved installers of a number of leading systems, from modified bitumen, thermoplastic membranes to reinforced liquid coatings, and we provide a first class service throughout New Zealand.

Below are some of the systems that we approve and use on new roofs and roof refurbishments:

   
         
    Double Layer Torch-on Bitumen Membrane System    
         
       
   
* Our applicators carefully seal around penetrations, vents, skylights, dormer windows and chimneys to ensure a leak-free roof.

What is Torch On Roofing?

Torch On Roofing generally consists of two plies of Modified Bitumen Membrane. Each ply, or layer, is approximately 3 - 4 mm thick.

The base ply is either mechanically secured (with screws through large washers referred to as ''plates'') or attached to the substrate by applied heat.

The cap sheet is similar in composition, but often has a granulated surface to provide protection from the elements.

Both the top surface of the base sheet and the bottom face of the cap sheet have a thermo-fusible plastic surface (meaning they can be joined together - or fused - thermally, in this case by melting both surfaces with a propane torch), thus the term ''Torch on Roofing''.
