Orb webs are usually rebuilt by the spider every night or two.

The longer version

Nightly repair keeps a trap effective. Sticky droplets lose water, dust settles on threads, and struggling prey tears holes, so a structure that looked fresh at dusk may be slack by the following evening. The cycle usually follows dusk, matching the hours when flying insects are most active.

Recycling the material recovers protein that would otherwise be wasted, since making silk costs a great deal of energy. Taking the structure down also lowers the builder's visibility to its own predators and allows relocation if nothing is passing through. In poor conditions the interval lengthens considerably.
