1. Deciding on installation strategy
2. Preparing the roof for fastening
3. Measuring and marking fastening points
Familiarise yourself with the results of the wind load calculation and decide on the
procedure for the installation.
Consider how best to deploy personnel, materials and equipment. In this way you
will achieve a fast, correct and efficient installation.
Prepare the roof for laying out the waterproof membrane (e.g. prepare substrate,
vapour barrier, thermal insulation, fleece etc.).
It is important to observe local regulations and manufacturers’ instructions.
We recommend that only so much roof area be prepared as can be fastened
and welded on the same day.
Before rolling out the waterproof membrane, steps 3 and 4have to be carried out.
Measure the locations of the fastening points in accordance with the wind load
calculation and mark these on the prepared roof surface using e.g. a chalk line.
