Commercial roof access gets treated as an afterthought until something goes wrong. Then everyone discovers the hatch has been propped open for years, the fixed ladder is missing its cage, nobody knows who was on the roof last week, and the skylights nobody has looked at since installation are brittle enough to step through.
Roofs are working surfaces on commercial buildings. HVAC techs, hood cleaners, telecom crews, inspectors and roofers all go up there, and the building owner sets the conditions they find. Getting access right protects people, protects the roof itself, and creates the record that answers questions after a leak or an incident.
Here is what building owners and property managers should have in place.
Getting On and Off the Roof Safely
The access point is where most problems start.
Roof hatches. A hatch needs a functioning hold-open arm so it cannot drop on someone, a working latch so it stays shut in wind, and a guardrail or safety post around the opening. An unguarded hatch opening is a hole in the walking surface as soon as it is open.
Fixed ladders. Rungs secure, stringers not corroding at the base, and a proper transition at the top. The most dangerous moment on a fixed ladder is stepping off it onto the roof.
Interior stairs. The safest access when a building has them, and worth keeping clear of storage.
Portable ladders. The riskiest option, and unfortunately the most common on older buildings. If a portable ladder is the only way up, it needs proper footing, tie-off at the top and someone who knows how to set it.
Whatever the access type, control it. Locked hatches and gated ladders keep the roof off-limits to people with no reason to be there, which prevents both injuries and unauthorized penetrations.
Edges, Openings and Skylights
Once someone is on the roof, three hazards account for nearly all serious falls.
Roof edges. Low-slope commercial roofs often have parapets that give a false sense of protection. A low parapet is not a guardrail. Where work happens near an unprotected edge — around perimeter equipment, drains or gutters — permanent guardrails or a designated tie-off system belong there.
Skylights and smoke vents. These are the ones that catch people out. An aged acrylic dome baked by North Texas summers becomes brittle, and it looks exactly like the one installed last year. Anyone walking a roof at dusk or across a snow-dusted surface may not see it at all. Screens, cages or rails around each unit are the fix.
Open hatches and unguarded penetrations. Anything that creates a hole in the walking surface, including a removed curb cover during service work.
Add to that the condition hazards a roof develops on its own — soft decking, ponding water, loose ballast, wobbling condenser stands and grease slicks near kitchen exhaust. A regular roof inspection should report on walking-surface safety, not only on watertightness. Our commercial roof inspection checklist covers what a thorough visit includes.
What to Expect From Anyone You Send Up
Every contractor on your roof should arrive with its own fall-protection plan, and you are entitled to ask about it.
Reasonable expectations:
- Current general liability and workers' compensation coverage on file
- A written fall-protection approach for work near edges and openings
- Trained crews who use harnesses, anchors or guardrails as the situation requires
- Ladders and equipment in serviceable condition
- Awareness of what the roof surface can take — no dropped tools on a membrane, no dragging equipment across it
Cannon Roofing crews are factory-trained and carry the Technician Seal of Safety, meaning they are background-checked and drug-tested before they ever set foot on a customer's property. Our article on roofing crew safety standards explains what that covers.
Documenting Who Goes Up and Why
The last piece is the simplest and the most neglected: a roof access log.
Record the date, the company, the person, the reason for the visit and the time down. It takes seconds at the hatch and it answers questions nobody can otherwise answer — which trade was up there the week before a leak appeared, whether a new penetration was authorized, who last serviced the unit sitting in a puddle.
Pair the log with a rule that any work touching the roof surface goes through the building's roofing contractor. Between the two, you know what is on your roof and who put it there.
A roof protection plan keeps scheduled visits, findings and photographs in one file, so access records and condition records live together rather than in separate inboxes.
Frequently Asked Questions
Who is responsible for safety when a contractor goes on my roof? The contractor is responsible for its own crew's fall protection, but the building owner controls access and the permanent features on the roof. Owners who keep hatches secured, guardrails maintained and access logged are in a much stronger position.
Do skylights need guardrails if the roof edge already has them? Skylights and smoke vents deserve their own protection. A weathered plastic dome will not hold a person's weight, and falls through skylights happen on roofs whose perimeters are fully guarded. Screens, cages or rails around each unit address it.
Should we track who goes up on the roof? Yes. A simple log of date, company, person and reason takes seconds and answers most questions later, including which trade was on the roof before a leak appeared and whether the visit was authorized at all.
