What does weatherproofing mean?
Weatherproofing is the process of making something resistant to the damaging effects of outdoor weather. It may refer to treating walls, roofs, windows, clothing, or equipment with suitable materials, or to the protective work itself. The term is also used as a verb: people weatherproof a structure by sealing joints, improving drainage, and selecting materials that withstand wind, rain, heat, and cold. In general and technical writing, weatherproofing usually implies more than keeping out rain; it suggests protection from a range of environmental conditions. Its connotations are practical and preventative, often associated with maintenance, durability, energy efficiency, and avoiding costly deterioration. The word is especially common in construction, DIY, and outdoor-equipment contexts, although related forms such as weatherization are particularly common in North American energy-efficiency discussions.

Where does weatherproofing come from?
Weatherproofing was formed in English by combining weather and proof with the suffix -ing, which can indicate either a process or an ongoing action. Weather descends from Old English weder or wæther, while proof entered Middle English from Old French prove, ultimately from Latin probare, “to test.” The resulting compound refers to making something resistant to weather, while its second element continues a word family associated with testing, proving, and establishing reliability.
