Torch applied membranes have an underside which has been pre-treated with a covering of
thermo fusible bitumen. This covering is then heated with a propane gas torch and the
membrane is applied to the surface of the roof while the bitumen is still hot. They are
reliable, cost effective, easy and fast to apply and leaks, if any, can be easily
Self Adhesive membranes have a safer installation process as there are no open flames,
lower fumes and the installation time frame is shorter. Lifetime Solutions offer 2
options of self-adhesive membranes.
Hot Mopped or Built Up Roofs are used mainly on low- slope roofs for commercial buildings.
They are made of successive layers of asphalt and roofing felts. After a base layer of
roofing felt, a coat of hot asphalt is applied. While the asphalt is still hot, a
layer of felt is embedded then another layer of hot asphalt, and so on until the roof
is built up to the desired number of layers or plies. The top coat can consist of a
number of possible finishes such as a torch applied membrane or bonded gravel.
