Rooftop Projection Screen - For Use With AtmosFX Projections

This is the rooftop screen projector hat I created for use during the holidays to project "digital decorations" form AtmosFX and other similar companies.
The frame was painted black when finished so that it's not so obvious at night. Where each tube was connected to a joint it was secured with four screws. EXCEPT the vertical part which was NOT permanently attached to the base so that I could remove it easily. (It would be a pain to remove four screws at each joint each time I wanted disassemble it.) This way it down-converts to two large sections that can be hung from the ceiling in the garage (what I do), or they can be stood up flatly against the wall if one wished.
To hold the projection screen material, I used large rubber twist ties that I got from Home Depot to anchor each eyelet of the screen material. But I attached a small S-hook to each twist tie. The twist ties are strong, and malleable, and can be adjusted longer or shorter as I wish so as not to overstretch the material. I didn't try to overthink it. I wanted something quick and dirty and the twist ties were great for getting me up quickly.
When placed up on the roof, I needed to angle the base to match the pitch angle of the roof. Each roof is different. So I had to put the whole thing up on the roof first and then move the vertical frame so that it stood straight upwards. So I didn't screw those joints into place until I was satisfied I had the angle right.
This type of frame made the wife happy because the project was not a permanent fixture and could be relatively removed once the holiday was over. 🙂
Notice how the back foot has a smaller surface profile area than the front foot. That's on purpose. I want the wind to have to fight hard to knock it over forward. But the back foot being smaller allowed me to push the whole assembly as far back up against the apex of the roof as possible while the foot's angle of placement itself made the wind still have to work kinda hard to blow it over backwards. (That's a lot of forward foot area to have to lift up and over.) But just to be safe, I'm going to add some sandbags to the front and back tubes on each foot to make it even more secure. Each sandbag will be painted black on only one side to hide them from view in the dark because I don't want to get black coming off upon the roof. Note that I've ALSO got some hefty eye hooks at each end of the top of the frame to allow me yet another method of anchoring if I feel it's needed.
UPDATE: I've actually used this frame now for two seasons - 2022 and 2023 as I write this. Had no problems with it.
I pay close attention to the weather forecast and if I feel that the weather will be too rough, I take the frame down from the roof. Otherwise I just take down the projection screen material and bring it inside for the night so as to reduce the chances of the wind ripping it to shreds in a rogue gust while I'm sleeping or while it's not being used during the day. And why subject the material to the daytime sunlight and heating too? Being kind to the material helps it to last that much longer.
The rooftop projections add just that more to the "Wow!" reaction for passersby to marvel at. Currently, we have projections in one bedroom window, hanging from a tree branch in the front yard (for ghosts actually floating IN the yard, too), on the garage door, on the rooftop, and upon three pumpkins nestled atop some hay bails in the front yard. During Xmas we swap the pumpkin projector to the side of the yard and project upon a blow-up 4-foot Christmas ornament nestled into a Christmas tree guard so that it looks like a giant snowglobe. :)
And I have intentions to add more projectors to the mix in the future. :) Maybe some snakes and spiders crawling around under the eve on the side of the house or something. Who knows. LOL! There's always room for something more!
