To ensure that every Sarnafil roofing system will stay on the building, no matter what the geographic location or height of the building, the Sika Sarnafil Technical Services Department calculates the wind load on every individual roof; ensuring the right method of attachment is chosen for the project.


Whilst many others leave the calculation of these critical factors to chance, or pass on liability to the roofing contractor, Sika Sarnafil use specialist software to design the roofing system to BS 6399: Part 2: 1997 code of practice for Wind Loads and also the new Eurocode, BS EN 1991-1-4: 2005 UK National Annex Method.


What’s more every Sarnafil roof benefits from suitable design insurance that indemnifies our work.
