My 2006 Jayco TT is at seasonal site. Its large slide goes out on spring's opening day, remains out all summer, then slide goes back in during fall's closing day (and remains closed during winter storage months). Been leaving the slide out during summer camping months since 2008 and never had a problem.
If at seasonal site (and will never tow again), I would create a hard top slide cover, screw its top edge to the trailer's roof line using large hinges and put next size smaller pins inside the hinges. Thus, allow some natural movement - without binding its hinges. then, install 4 x telescopic steel poles - so weight of hard top cover doesn't rest on the slide's outer edge.
For a few pictures of my TT's hard top slide cover, surf:

Thus, snow slides off the slide cover. In the spring, simply raise the hard top, tighten bolt on telescopic poles, then put slide back out.
If into store bought hard cover for a slide, surf:
