Roof Access Procedures¶

ACTIVE SOP

Pre-Access Checklist¶

Before ascending any structure:

• [ ] PPE complete — non-slip boots, gloves, safety glasses (see PPE Standards)
• [ ] Ladder inspected — no bent rails, all feet present and functional, locking spreaders engaged (step ladder)
• [ ] Ladder secured at top (leaned ladder) or locked (step ladder)
• [ ] Weather assessed — no wet surfaces, no wind advisory, no active precipitation
• [ ] Fall protection decision made based on height and pitch (see below)
• [ ] Lead tech notified of roof access

Ladder Safety¶

Leaned Ladder (Extension Ladder)¶

• Lean ratio: 4:1 — for every 4 feet of height, base is 1 foot from wall
• Extend at least 3 feet above the roof edge or landing point
• Secure the top before ascending — tie-off or have a spotter
• Face the ladder when climbing — three points of contact at all times
• Never carry tools in your hands on the ladder — use a tool belt or bucket

Step Ladder¶

• Only use on level, stable ground
• Spreaders fully locked before any weight
• Do not stand on top two rungs
• Do not lean sideways beyond the rails

Flat Roof Access¶

Most commercial sites have flat or low-slope roofs (≤2:12).

• Safe to walk without fall protection if parapets are ≥39" high
• If no parapet or parapet below 39", fall protection required within 6 feet of edge
• Watch for:
  • HVAC equipment, skylights, and penetrations
  • Soft spots (especially near drains)
  • Ballasted gravel that shifts underfoot
  • Hot surfaces in summer (protect hands, hydrate)

Pitched Roof Access¶

For residential pitched systems (>2:12):

• 4:12 or steeper: fall protection required
• Roof brackets and planks for extended work at slope
• Avoid walking directly on panels — stay on structural members if possible
• Move slowly, test footing before each step

Fall Protection Requirements¶

Electrical Hazard on Roof¶

• PV modules are always generating voltage in daylight
• Avoid stepping on or between modules unless there is no alternative path
• Never place tools or ladders on module surfaces
• If wiring is visible and not in conduit, assume it is energized
