Mounting props on a roof

Hey just wanted to see if anyone had some advice on how to mount this merry Christmas to my colourbond roof. I have just built a new house and I am in the final stages of working out all new spots for my props to go. As I stood back and looked at my whole display I thought mounting the merry Christmas to the roof would look amazing as I have a high pitch roof it will work perfectly but not quite sure how to go about mounting it if anyone has done something similar or has any ideas it would be much appreciated. At the moment it is mounted to 25mm electrical conduit which works well as a frame but just not sure how I could mount it to the roof. Thanks

they look so much better painted

Have you already glued it together? If not you can cut it and load up some t pieces and mount on the roof similar to this. I've mounted my flakes with 25mm saddle clips mounted on the screws in my colorbond.

Do you want it to stand up vertically, or be flat against the roof?

I have not had good luck trying to mount these with conduit.

made a similar frame for some props and just put tube back on an angle using delta inspection tees so the props were just off vertical and fall back a little and then added sand bags to hold it down

where i needed the delta tees to go four ways i replace the inspection lid with a 3D printed fourth leg
