A roof can look fine from the ground and still be carrying a long list of small problems by the time cooler weather rolls in. Leaves pile up, rain hits harder, temperatures swing from warm afternoons to cold nights, and every weak spot gets tested. That’s what makes fall such a big deal for a commercial roof. It’s the season when summer wear starts showing up, and it’s also the last good window to catch problems before winter makes repairs slower, messier, and more expensive.
