Weather changes what an inspection can see, in both directions, and the report should record which conditions applied. Rain reveals active leaks, gutter overflow, grading failures and drainage paths that are invisible on a dry day. Snow conceals the roof surface, the grade and the site entirely. Prolonged dry weather hides seepage that would appear after a storm. Frozen ground prevents assessing drainage. Extreme cold makes it unsafe to run an air conditioner, and extreme heat does the same for a furnace, so equipment testing is limited by outdoor temperature. None of this invalidates the inspection; it bounds it. Noting the weather lets the client understand why certain observations were or were not possible and, where it matters, decide whether to look again under different conditions.
