For any roof installation, we always recommend 12mm Lazy Foam or Lazy Pad to be laid over the current roofing system for domestic installations and the inclusion of a cuspated drainage layer for commercial projects. Both systems allow free drainage of rain water and protects the roof membrane. Using a shockpad and drainage layer also allows the artificial grass to be fixed to the underlay and not the roof surface.
Due to the varied surfaces of roof areas, great care has to be taken before attempting to use adhesive on PVC membranes, as this can cause serious damage and invalidate roofing warranties. For this reason, we recommend you first contact our sales or technical team on 01572 768208 to ensure the correct fitting method is used.
