Corner on roof need help

[cynthi57]

I have a 98 Yosemite heritage with I think an abs roof. Th corners at the front have cracked and the wood and part of the clamps are missing. Any suggestions on how to fix this and add extra support. Also there is one long crack on one side that I think need to be stabilized to fix.

I'm seeing a previous repair with fiberglass screen in the first and third pictures. Maybe some fiberglass cloth and resin to repair them this time. If that roof is age degrading, it may be an ongoing process.

I tried fixing it with dry wall tape. It worked on the small cracks but not the large ones. I’ve been thinking of trying plastic welding to see if that helps but I don’t know how to reinforce it.!

That plastic is very old and is disintegrating.May just keep crumbling.
Could try mesh drywall tape and ABS cement .Add layers then sand.

You may wanna look into eterna bond tape that stuff is fantastic.
