Stages and drape
Outdoor stage roofs: configuration and weather plan
Treat the roof, walls, loads and site as one documented arrangement.
Define the roof and exposed surfaces
Ask GLMedia about rental options for your event. The proposal is subject to availability, confirmation of the model and configuration, and the venue’s technical requirements.
A stage deck does not approve an overhead roof. Identify the roof system and revision, towers, canopy, walls, ground supports and all attached equipment. Define the actual event location and exposure.
Configuration and weather conditions
- Configuration matters
- The Arc Roof example distinguishes in-service and out-of-service conditions and configuration-dependent ballast. Its values do not apply to every roof.
- Lightning planning
- NWS guidance calls for weather planning and suitable shelter; a tent is not lightning shelter.
Obtain the complete system manual and project structural assessment. Operating limits and permitted actions must match the actual configuration and site.
Roof, canopy, anchoring and response plan
Prepare roof and load drawings, approved canopy and wall arrangement, bracing, ballast or anchors, bearing plan, weather monitoring and an event response plan. Include LED walls, signs and speaker loads.
Agree monitoring, decisions and actions
- Verify the supplied configuration against the approved design before assembly.
- Assign weather monitoring, decision authority and communication to the event team.
- Plan time and conditions for stopping work, clearing areas and reaching suitable shelter; confirm inspection and reopening responsibilities.
Three technical questions
Is there a wind speed that works for every stage roof?
No. Obtain limits and actions from the actual design, including gust definition, measurement and configuration. Do not borrow another system’s threshold.
Can sidewalls be added just to keep rain off equipment?
Only after review of the complete configuration. Walls and signs change exposure and structural actions; protect equipment with an approved arrangement.
Should the roof always be lowered when wind increases?
No universal action applies. Follow the approved response plan and permitted intervention conditions. Do not improvise a roof movement or canopy removal in hazardous weather.
Before the event, record who issues the stop instruction, how crews and attendees are informed, which technical actions are permitted and how much time they need. Include shelter routes and the conditions and authority for reopening. Plan decisions early enough for those actions to be completed within the approved conditions.
Before anyone uses the stage
Keep evacuation independent of equipment recovery. Electrical bonding does not establish lightning shelter. Changes to canopy, loads or anchoring require review before use.
