Fragile Surfaces & Roof Work

Roof access control, fragile materials such as rooflights and cement sheeting, crawling boards, perimeter protection and the heat-related constraints specific to UAE roof work.

Which rules apply: Abu Dhabi vs Dubai

The ADOSH-SF references on this page (CoP 23.0, CoP 26.0 and CoP 37.0) are Abu Dhabi instruments issued under the ADOSH-SF Occupational Safety and Health System Framework, and they are what an Abu Dhabi inspector will audit fragile surfaces & roof work against.

In Dubai the equivalent legal reference is the Dubai Municipality Code of Construction Safety Practice, with Trakhees EHS requirements in PCFC areas and DDA rules in Dubai Development Authority areas. Other emirates apply their municipal building-permit safety conditions — Sharjah uses OSHJ-CoP-04, RAK free-zone projects use the RAKEZ HS&E Construction Regulations. Federally, MOHRE Ministerial Resolution 32 of 2022 applies everywhere.

The controls below are technically equivalent across emirates, so ADOSH-SF is widely used as the project benchmark — but cite your own emirate's code on permits, method statements and inspection records.

Identify Fragile Before Anyone Steps On It

Any roof or surface that cannot safely bear the weight of a person and their tools is fragile. In the UAE this most often means fibre-cement sheeting, polycarbonate/GRP rooflights, corroded profiled metal deck, and asbestos-cement sheets on older industrial buildings. No one should step on a roof surface until it has been assessed and confirmed load-bearing in writing.

Pre-access survey
Structural/competent-person assessment of the deck before first access
critical
Asbestos check
Asbestos survey completed for pre-2000 industrial roofs before any disturbance
critical
Signage at access
'Fragile roof — do not access without a permit' at every ladder, hatch and stair
critical
Rooflights
Treated as fragile in all cases and covered, guarded or netted
critical
Crawling boards / staging
Load-spreading boards used where the deck cannot be walked on
critical
Permit to access roof
Issued per shift with the access route and controls stated
critical

Roof Edge and Perimeter Protection

Perimeter guardrail
Double guardrail plus toe board at every roof edge where access occurs
critical
Free-standing counterweighted systems
Used only within the manufacturer's slope and wind limits with the correct counterweight count
critical
Demarcation zone
Only acceptable ≥2 m from the edge with a physical barrier and supervision
standard
Roof access ladder / hatch
Guarded landing area with the hatch secured open or closed
critical
Materials on roof
Secured against wind; no stacking against the guardrail or over rooflights
critical

UAE Heat and Roof Work

Roof surfaces in Abu Dhabi and Dubai routinely exceed 70 °C in summer. This causes burns on contact, degrades harness webbing and ropes, softens membranes so they will not bear point loads, and accelerates heat exhaustion — which is itself a leading cause of falls.

Midday ban
No roof work 12:30–15:00 from 15 June to 15 September (MOHRE)
critical
Surface temperature check
Measured before access; membrane work suspended when the surface will not bear load
standard
Shade and rehydration
Shaded rest point and cool water within the work area
critical
PPE for hot surfaces
Heat-resistant gloves and knee protection for kneeling work
standard
Equipment protection
Harnesses, ropes and nets kept off hot surfaces and out of direct sun between uses
standard
