Also... a quick note about me doing the screwless installation... say the new skylight comes with screw holes... instead of using SCREWS... I put SEALANT in those screw holes. Wiggle and press down... and the sealant comes up through the screw holes.. and once it dries... acts like "SEALANT SCREWS or DOWELS" of a sort that will "grip" the skylight flange by having sealed/dried through the flange screw mount holes. While I'm pretty confident about this idea working well, I won't know till I try it. :)
Honestly, I can't understand your disdain for screws.. But it doesn't surprise me that you are fool hardy to believe it will work..
Perhaps you should consider using BETTER screws like these..
Which are designed for steel roofing panels and have a built in rubber washer which creates a darn good seal.. I have used metal roof washers which are washers with the rubber seal that you can add to any screw, work very well and NO LEAKS around any of my roof items.
Much better than your glue only method to which I can't wait to see your cry for help posting about losing your skylight while traveling..
I would NOT recommend relying solely on GLUE to hold that skylight on, that skylight WILL experience wind speeds near hurricane force numbers. Driving say 65 mph and encountering a 20 mph head wind is like a 85 mph hurricane force wind speed..
On a two lane road (one lane each way) and you are driving 55 MPH and encounter a semi coming at you that vent will see 110 MPH windspeed and add in a 20MPH head wind you are now at 130 MPH wind!
If a manufacturer has ALREADY placed screw holes, one MUST consider that they put them there for a darned good reason..
And if you use the wrong glue it may not adhere well to the skylight plastic or the roofing material or even never dry at all.. One heck of a gamble that I would not be willing to take..
