Does weather exposure actually meaningfully degrade the value of stored scrap metal over time?
Short answer: For some metals, yes meaningfully — extended exposure to rain and moisture can cause visible corrosion on ferrous metals in particular, which some buyers may factor into a lower offer, while other metals like aluminium and stainless steel are more weather-resistant, meaning the practical importance of weather protection varies by the specific material you're storing, with ferrous scrap and any electrical components generally benefiting most from basic weather protection.

Steel and iron are genuinely prone to rust when exposed to moisture over extended periods, and while light surface rust doesn’t eliminate scrap value entirely, more significant corrosion can affect both weight (through material loss) and how a buyer assesses the material.
Why some materials are naturally more weather-resistant
Aluminium, stainless steel, and copper are all considerably more weather-resistant than plain steel or iron, meaning the practical urgency of weather protection varies genuinely by the specific material composition of what you’re storing.
Why basic protection is a low-cost, worthwhile precaution
A simple tarp or basic cover, particularly for ferrous material or anything with electrical components, is a low-cost way to preserve value during any storage period, regardless of how long you ultimately plan to store material.
