The list spans technical seminars, trade shows, and industry conventions running from January through May, with enough range to suit contractors, building envelope specialists, and commercial roofing crews at different stages of the year. The IIBEC International Convention and Trade Show in Sacramento runs mid-March and draws envelope consultants and inspectors from across North America. The RICOWI Spring Seminar, also in Sacramento, follows just days earlier, which makes that stretch of March a practical window for California-based operators to stack both without extra travel. If you're tracking the international roofing expo 2026 calendar and trying to plan where to show up, build relationships, or stay current on code and materials, this page gives you dates, locations, and enough context to make the call.
