Mount my solar panel with double sided tape????

If you have a rubber roof (or like us a thin ally sheet roof) just sticking with tape or Sikoflex type stuff will only stick the panels to the roof covering-------If (when) the rubber/ally seperates from the roof board the panel can fly off and take a big lump of roof cover with it !
I used Sikoflex AND screws on ours
