Before the sun's expansion renders the surface of the Earth uninhabitable? Probably not. Most of the Earth's surface will be scoured clean of our influence pretty quickly, geologically speaking. However, there will remain islands of relative stability that will keep ruins of our civilization afloat for possibly hundreds of millions of years.

Consider the fact that although rare, we still find fairly complete dinosaur fossils. Bone from 200 million years ago is still recognizable. We make a lot more resilient and robust materials than bone. Often in huge quantities.

Those skeletal fossils survived that long by being buried and later exposed through erosion. This same process will occur for human ruins as well. They will be buried by the elements and then re-exposed at different rates in different locations, so its pretty much guaranteed that there will still be detectable ruins of structures somewhere at pretty much all times.

Most of what we've created won't last nearly that long though.

Coastal cities in the path of monsoons and hurricanes will be washed away within thousands of years. Same with big cities near major rivers as they twist and carve up the land.

Tens of millions of years are enough for life to rebound after anything we can do to it, and regrowth will breakdown and bury much of our societies efforts. But all of it?

Even continental drift and major natural disasters won't be able to scour everything away. Take a look at the wiki page for Crantons - https://en.wikipedia.org/wiki/CratonCratons. Basically there are regions of stability within the continental plates that haven't changed much over the range of 500 million years. Surface erosion still occurs, but those regions won't likely be subducted deep beneath the crust... ever.

I would wager that remains of human establishments will have a decent chance at surviving for a VERY long time if they are situated in the right spot. If you want to go far enough ahead that detecting human civilization becomes very unlikely, 50-100 million years is probably a good bet.

Oh and satellites aren't really worth worrying about. One of our most stable orbits are graveyard orbits above geosynchronous orbits. Those will last for probably millions of years, but gravity and solar wind will eventually reclaim them as well. https://space.stackexchange.com/questions/18056/how-stable-are-satellites-in-a-graveyard-orbit
