Roof Work Accident Statistics UK: 2026 Facts, Data & Key Insights

Roof Work: The Highest-Risk Construction Activity

Working on roofs is among the most hazardous activities carried out in the UK construction industry. The HSE is explicit on this point: roof work accounts for a quarter of all deaths in the construction industry. Every day, workers on commercial and domestic roofs across the UK face risks from roof edges, fragile surfaces, rooflights, and adverse weather — risks that are well understood, legally regulated, and still causing deaths.

In 2024/25, falls from height claimed 35 lives across all industries in Great Britain. Construction accounted for a disproportionate share, with falls from height responsible for over half of all construction deaths over the five-year period. And within construction, roof work is consistently the most over-represented category.

Key Facts & Figures (Overview)

Why Roof Work Is So Dangerous

Several characteristics make roof work inherently more hazardous than other construction activities:

Edge risk on every project: All roofs have edges — parapet walls, eaves, verges — and on most UK buildings these represent an unguarded drop that can be fatal. Edge protection (scaffolding or proprietary edge protection systems) is the primary control, but is frequently absent on smaller domestic projects.

Fragile surfaces: Many UK roofs — particularly older commercial and industrial buildings — incorporate fragile materials that cannot support the weight of a person. Asbestos cement sheets, skylights, older fibre cement panels, and deteriorated roof sheets may appear solid but will give way without warning. HSE guidance specifically states that all roofs should be treated as fragile until a competent person has confirmed otherwise.

Fragile rooflights: Rooflights (skylights) present a specific hazard — they are often indistinguishable from solid roof panels in certain light conditions, or may be obscured by paint or weathering. Workers who step on a rooflight expecting it to bear their weight can fall through without warning.

Working on pitch: Sloping roofs require scaffolding not only around the perimeter but also on the roof surface itself — crawling boards, roof ladders, and working platforms that allow workers to distribute their weight without applying concentrated load to individual tiles. Working directly on pitched roof tiles without crawling boards is both dangerous and illegal.

Weather exposure: All roof work is conducted outdoors, fully exposed to weather. Rain, wind, ice, and frost all dramatically increase the risk of slipping from a pitched or flat roof. HSE guidance requires that weather conditions be monitored and that work be suspended when conditions create unacceptable risk.

Fragile Roofs: The Specific Hazard

Falls through fragile materials are the leading single cause of roofing fatalities in the UK — more common even than falls from roof edges. The HSE's Health and Safety in Roof Work (HSG33) guidance dedicates specific sections to fragile roof management because of its disproportionate contribution to deaths.

Key fragile roof hazards:

Asbestos cement (AC) sheets: Widely used on agricultural and industrial buildings constructed before the 1980s. These sheets deteriorate with age, losing their structural integrity while maintaining their appearance. AC sheets that look solid from above may collapse under the weight of a person. Many deaths have resulted from workers stepping onto AC sheets during maintenance work believing them to be safe.

Fibre cement sheets: The non-asbestos replacement for AC roofing carries similar fragility risks as it ages. All sheeted roofs should be treated as potentially fragile.

Rooflights and skylights: Glass, plastic (polycarbonate, GRP), and wired glass rooflights should all be treated as fragile. Purpose-designed fragile roof covers, secured and labelled with warnings, are the required control measure where rooflights cannot be removed or replaced.

Older flat roofing membranes: Deteriorated bituminous felt and some earlier waterproofing systems can become brittle and fragile over time.

The Domestic Roofing Problem

A specific and persistent pattern in UK roofing deaths is the involvement of smaller builders working on domestic dwellings. The HSE specifically identifies this category: "Many deaths occur each year involving smaller builders working on the roof of domestic dwellings."

The reasons are clear. Small builders undertaking domestic roofing jobs — replacing tiles, repairing flashing, fitting roof windows — may not invest in the scaffolding that the job legally requires, either because of cost pressure, time pressure, or a mistaken belief that the job is too small or too quick to justify it. A domestic roofer working from a ladder to a slope without edge protection has no second chance if they slip.

Domestic clients who hire builders without verifying their competence and safety practices contribute to this pattern — and under the Work at Height Regulations, clients have obligations to ensure that those they appoint to work at height are competent.

The Legal Framework for Roof Work

The Work at Height Regulations 2005 apply in full to roof work. Additional specific guidance is provided in HSE's Health and Safety in Roof Work (HSG33 — 5th edition).

Key requirements for roof work include:

Prosecution cases: The HSE regularly prosecutes roofing companies and building contractors for roof work fatalities and near-misses. A construction company and roofing contractor were fined in 2024 after a roofer suffered multiple fractures in a fall from an unprotected roof edge. British Airways was fined over £3 million in 2025 for falls from height at Heathrow — demonstrating that height risk extends far beyond the traditional roofing sector.

This guide was produced by the team at Working at Heights Course, a UK provider of RoSPA and CPD-accredited online working at height training. Roof work carries some of the most serious height risks of any UK activity — and training that covers fragile roof identification, edge protection requirements, and safe roof access procedures is essential for anyone who accesses or manages roof work.
