Hey bud, get the double sided 3m tape with the red ribbon 'around the edges', making sure to dab sikaflex in the middle of it 'the generator, not the tape', '1cm diameter', every 1-2inches.

You can also splice the tape to incorporate drain outlets so you wont get excess water build up across the top.

Problem with excess sikaflex is it may force a roof respray if you decide to remove it later on 'therefore less, strategically placed = better'.
