Roof Access Permit

This permit governs going onto a roof: the surface, the route, the edge and the day's conditions. Work that happens to be at height but not on a roof, and roof work that adds a further hazard, belongs under the neighbouring permits, alone or alongside this one.

Roof access sits under the general walking-working surfaces and work at height regimes rather than a dedicated roof statute. The regulation is prescriptive about fragile surfaces, edges and fall protection, and silent on permits, which makes the permit the employer's own evidence that the prescriptive duties were checked before each entry.

No major regime writes a roof permit into law. What the law prescribes is the outcome, fragile surfaces not walked on, edges protected, weather respected, and the permit is the mechanism by which an organisation proves those duties were discharged entry by entry.

The form asks the right questions. Whether the record it produces would survive an investigation depends on four judgement calls the form cannot make for the issuer.

Roof access findings split into two families: gates answered without evidence, and permits that were valid on paper while the conditions or the work had moved on.

A dairy site raised a roof access permit for a contractor to trace a leak above the packing hall. The issuer, the facilities coordinator, answered Fragile Areas Identified as None present, on the basis that the roof had been recoated two years earlier and looked uniform from the yard. Edge protection passed, the weather passed, and the permit was issued for the shift.

The contractor's fitter followed the drip line, stepped off the walkway to reach a suspect lap joint, and put his boot on a roof light that had been over-coated in the same paint as the sheets. It held, flexing enough to crack, and he threw his weight back onto the purlin line. The near miss report noted that the recoating contractor had painted across eleven roof lights, and that the roof plan in the maintenance office, which showed every one of them, had not been opened; Roof Plan Reviewed had been marked Pass because a plan was known to exist.

The investigation's finding was not that the coordinator was careless. It was that the permit allowed a fragility judgement to be made from the yard, and treated the existence of a document as the review of it. The fix was procedural and small: the fragility gate now names its evidence, the roof plan is attached to the permit, and painted-over roof lights were barriered within the week. What did not change was the roof, which had been lethal and uniform-looking for two years of compliant-looking permits.

The permit itself is a page of gates. What fails around it is the machinery: the roof survey nobody refreshed, the anchor inspection that lapsed, the contractor induction assumed rather than checked, and the hatch left unlocked after closure.

KnowSafe

Runs the permit through its gates, blocks issue while any gate is unresolved, and holds every refusal with its reason as part of the site's evidence trail.

Ella

Cross-checks the permit's references at issue, the anchor against its register, the height permit, the isolation, and flags a fragility answer that has no survey behind it.

KnowMaintain

Links the permit to the work order that put people on the roof, and to the roof plant assets whose isolation status the Gate 3 answers depend on.

KnowContractor

Holds the roofing contractor's approval, induction and method statement so the permit's contractor gates are verified against records rather than answered on trust.

Fragile surface

A surface that would fail under the weight of a person and any load they carry, including roof lights, aged cement-fibre sheets and corroded metal decking.

Roof light

A translucent panel set into a roof for daylight. It weathers to match the surrounding sheets and is the single most common surface in fatal fall-through incidents.

Low-slope roof

In US practice, a roof with a slope of 4 in 12 or less, to which the distance-based fall protection options of 1910.28(b)(13) apply.

Designated area

A US mechanism: a warning-line-bounded area at least 6 feet from the edge in which temporary, infrequent work may proceed without conventional fall protection.

Edge protection

Collective protection at the roof perimeter, guardrails, parapets of adequate height, or barriers, preferred over personal systems in every major regime.

Crawling boards

Staging laid across a fragile roof to spread load onto the structure beneath, so that the surface itself is never asked to carry a person.

Anchor point

A certificated attachment for personal fall protection, with a register entry, an inspection history and a rated capacity, referenced by the permit rather than created by it.

Exclusion zone

A barriered area at ground level beneath the work, protecting people below from dropped tools and materials, and one of the permit's Gate 3 conditions.
