The "D" hollow ridge seal peels off far too easily if the roof erection is slightly out of sequence. IMO sticky tape is a pitiful method to hold the seal in place. Has anyone tried the following: Install aluminum flat bar inside the hollow ridge seal. Clamp to roof, drill "tap sized" holes at 12" OC thru the roof and thru the flat bar. Note which end is which then remove all parts and pieces. Drill holes in roof to clear new stainless machine screws. Tap the holes in the flat bar for threads of the same machine screws (maybe 1/4"-20 UNC). Slide flat bar back inside ridge seal and assemble in place, which machines screws now holding the flat bar which locks the D" seal in position. This would be much easier to do when changing the bungee cords - which I am about to do.
