With a utility knife, make long, straight cuts either down the room’s long axis or across it. Space the cuts two to three feet apart. This is recommended so you can move the carpet pieces with ease. Wet carpet is heavy.
Take one strip and roll it. The weight of the roll will depend on the type of carpet and how wide the strip is. Crosscut the roll so that you can comfortably lift it, either by yourself or with a second person.
To move a roll, grab one end of the carpet, or stick a hay hook in the center of the roll and lift or drag. The hay hook method is efficient especially if you can work with a second person, each with a hook.
Use a framing hammer and flat bar to remove the carpet tack strip, which you’ll find underneath the carpet. You may be tempted to leave it in place, but be aware that it will rust if it’s gotten wet, and debris trapped under and behind it can give off an awful stink. Also remove the carpet under-layment and stuff it into contractor-grade plastic bags.
Pile the debris outside, but cover it with a tarp so it doesn’t get any wetter. Weigh the tarp down or stake it so it doesn’t blow away.
