    Default Roof mount

    My parents display has a large wire frame setup of Santa, 7 reindeer and a few other misc items on the roof made from 3/8 rebar. The tallest is Rudolph which has a ~8 stand holding him up for a total of about 12. For the first 35 years these have been up, my dad had a piece of redwood drilled and lag screwed into the roof about a 1 from the peak. We then used some small clamps over the rebar to screw then into the redwood and then attached a few guywires on each side of each element and tied them to eye screws also screwed through the roof. That worked well but but my parents just had a new roof installed along with solar and we want to not put any holes into it. Working with the roofer they put in some heavy anchors were we used to have the eye screws so we have strong weather proofed locations for the guywires. What I am trying to figure out is how to build a removable platform to mount the wire frames to. I was thinking of building something out of either 1 tube steel or some sort of wood that would straddle the roof peak that I could screw a 2x4 to that I could then anchor the wire frames to. Most of the holding strength for the wire frames will come from the guywires. Any thoughts or setups you guys have seen? Thanks

    Here is a short video when the roof is on. We run it for about a minute between music and typically leave it off during a song as it’s really hard to sequence in. https://youtu.be/YKqk7p0UqJE

    Same as what you had but don't screw to roof. Make a "brace" that holds the front side and back side. Could be made out of lots of thing. My first thought is rebar bent so that it does not touch the peak and with anchors on both sides bent out parallel to roof line. Second idea is a PVC shelf. A couple of side braces. Probably pretty big diameter to create the support needed especially if the guy wires will be taut. don't be afraid to anchor the boards to the guy wire anchors and/or use sandbags.

    Hope you figure out a way to put it back up there. It looks great as does the whole display. Nice job building and setting up.

    I’d probably just run a 2x4 board along the ridge and brace it with horizontal outriggers that match the roof pitch. Weld up the outriggers from some re-bar or square tube. That’ll hold the base “plate” on the roof, and then your guy wires will do the rest.
