Single ply

A single ply membrane gives water resistance with only a single sheet of roofing material. It is an established and proven technology in use up until this present time

Built up roofing

Built up roofing (BUR) is considered the most common flat roof solution in the world today. Similar to single ply roofing, BUR is also usually utilized on capital intensive projects.

BUR roofs consist of several layers of reinforced bituminous membranes. Unlike the single ply alternatives, its layers are bonded, thus giving roofs more sturdy looks. This indicates that BUR is suitable for any place bound to experience periodic foot traffic.

However one must be very careful while installing because it involves dangerous hot works. Thus, an experienced installer should take charge of health and safety on site.

Cold applied liquids

These are comparable to hot melt roofs, albeit one clear distinction; the waterproof membrane in this case is cold. Hence, installations are easier and the hazards of hot works are absent.

Cold liquids are cost effective and mostly applied on renovation projects. However, in restricted working environments such as balconies, cold applied liquid roofs are suitable and on increasing demand because of the flexibility and comfort of installation.
