DIY roofing injuries send tens of thousands of Americans to the emergency room every year, and almost all of them start the same way: a fall from a ladder or a roof edge. The U.S. Consumer Product Safety Commission (CPSC) attributes more than 164,000 ER-treated injuries and roughly 300 deaths a year to ladder falls, and the American Academy of Orthopaedic Surgeons (AAOS) puts total medically treated ladder injuries near 500,000 annually. A 1990 to 2005 analysis in the American Journal of Preventive Medicine found more than 90% of ladder-fall injuries happened in non-occupational, mostly residential settings, which is where DIY roof work lives. This report pulls the federal injury data apart to answer the question a homeowner actually has before climbing up: how likely is a serious injury, and where does the danger really come from.
Key findings
- Ladder falls injure more than 164,000 people badly enough for an ER visit each year, and kill about 300, per CPSC estimates.
- Over 90% of ladder-fall injuries occur in non-occupational, mostly home settings, per a 1990 to 2005 study in the American Journal of Preventive Medicine, which counted more than 2 million serious ladder injuries across that period.
- Roofs and ladders are the two deadliest sources of construction falls. Roofs accounted for about 32% and ladders about 24% of fatal construction falls in 2015 to 2017, per CPWR analysis of BLS data.
- Most serious ladder falls happen at low, safe-feeling heights. Falls of 6 to 10 feet caused about half of ED-treated ladder-fall injuries, and nearly 90% came from under 16 feet, per CDC (2011 data).
- Fractures are the signature DIY roof-work injury, making up the large majority of serious ladder-fall cases in the AJPM analysis.
- DIY roof injuries are seasonal, climbing through spring and summer as home-improvement activity rises, per UW Medicine trauma reporting from Harborview Medical Center.
How many people get hurt doing DIY roof work each year?
Ladder falls, the dominant mechanism in DIY roof work, injure more than 164,000 people badly enough for an emergency room visit each year and kill about 300, according to CPSC estimates. Because federal surveillance does not tag injuries as “DIY roofing” specifically, the honest way to size the DIY slice is to start with ladder-fall totals and apply the finding that the large majority happen at home. The table below stacks the outcomes into an injury pyramid.
| Outcome level | Approximate annual U.S. count | Source (year) |
|---|---|---|
| Deaths from ladder falls | ~300 | CPSC |
| ER-treated ladder-fall injuries | 164,000+ | CPSC |
| All medically treated ladder injuries (any setting) | ~500,000 | AAOS |
| ED-treated ladder injuries, annual average 1990 to 2005 | 136,118 | Am. J. Preventive Medicine (2009) |
| Share occurring in non-occupational (mostly home) settings | >90% | Am. J. Preventive Medicine (2009) |
The figures differ because they count different things. CPSC’s 164,000 counts only hospital emergency departments through its National Electronic Injury Surveillance System (NEISS). The AAOS number near 500,000 folds in urgent care and doctor visits, so it runs higher. Both point the same direction: ladder falls are a large, steady source of preventable injury, and DIY roof work sits squarely inside them.
DIY vs professional: who actually gets hurt on roofs?
Professionals die at higher rates per worker, but homeowners absorb the larger raw share of ladder-fall injuries because so much roof work happens at home. Roofing ranks among the top three deadliest U.S. occupations, with a fatal-injury rate near 57.5 per 100,000 workers in recent BLS Census of Fatal Occupational Injuries data, and roughly 80% of roofer deaths trace to a fall, slip, or trip. Yet the AJPM analysis found more than 90% of all ladder-fall injuries happen off the job.
The occupational data still matters for DIY, because it reveals the mechanism. In 2011, CDC counted 113 work-related ladder-fall deaths, about 34,000 ED-treated nonfatal ladder-fall injuries, and 15,460 employer-reported cases with days away from work. Construction carried 64 of those deaths (57%) and an estimated 11,500 ED-treated injuries. Critically, CDC reported that about 81% of construction fall injuries treated in emergency departments involved a ladder. A homeowner on the same ladder, without a harness, training, or a spotter, faces the same physics with fewer safeguards.
| Metric (2011 occupational data) | All industries | Construction |
|---|---|---|
| Work-related ladder-fall deaths | 113 | 64 |
| ED-treated nonfatal ladder-fall injuries | ~34,000 | ~11,500 |
| Employer-reported cases, days away from work | 15,460 | 3,600 |
| Share of fall ED injuries involving a ladder | n/a | ~81% |

The counterintuitive risk: most serious falls happen at low heights
The most dangerous fall is not from a steep two-story roof; it is from the height a homeowner assumes is safe. CDC’s analysis of ED-treated ladder-fall injuries found that falls from 6 to 10 feet caused about half of all cases, and nearly 90% of injuries came from heights under 16 feet. A single-story eave, a gutter line, or the third rung from the top clears that bar easily.
| Fall height | Share of ED-treated ladder-fall injuries |
|---|---|
| Under 6 feet | Meaningful share; injuries begin at low rungs |
| 6 to 10 feet | ~50% (the single largest band) |
| 10 to 16 feet | Brings the cumulative total to ~90% |
| Over 16 feet | ~10% |
Source: CDC (2011 ED data). The takeaway holds across the research: a fall of 10 feet onto a driveway can fracture a wrist, hip, or skull. The perception that low ladder work is low risk is the trap, and it is why gutter cleaning and single-story repairs generate so many injuries.
Where do fatal roof and ladder falls come from?
Roofs and ladders are the top two sources of fatal falls in construction, and the pattern is a useful benchmark for the DIY hazard because the surfaces and heights are identical. Analysis of BLS data by CPWR found roofs caused about 32% and ladders about 24% of fatal construction falls in 2015 to 2017. Across 2011 to 2016, BLS recorded 836 fatal ladder falls and 763 fatal roof falls in construction.
| Primary source of fatal fall | Share of construction fall deaths (2015 to 2017) |
|---|---|
| Roofs | ~32% |
| Ladders | ~24% |
| Scaffolds, staging, other structures | Remainder |
Source: CPWR analysis of BLS Census of Fatal Occupational Injuries. Falls remain the leading cause of construction death overall: BLS recorded 370 fatal falls, slips, and trips among construction and extraction workers in 2024, down from 400 in 2023, out of 1,032 total deaths in the group.
When do DIY roof injuries peak?
DIY roof and ladder injuries rise through spring and summer, tracking the home-improvement calendar. UW Medicine trauma staff at Harborview Medical Center report treating someone seriously hurt by a ladder fall every few days across the warm-weather months, when homeowners return to gutter cleaning, roof repairs, and holiday-light hanging after a sedentary winter.
The seasonal spike matters for planning. Wet leaves, roofing granules washed into gutters, and moss on north-facing slopes make surfaces slick in exactly the shoulder seasons when people climb up to clear them. If a task can wait for dry footing and a helper on the ground, the risk drops sharply.
What causes DIY ladder and roof falls?
Most DIY falls come from a small set of repeatable errors, not freak accidents. The mechanics are consistent across CDC and ladder-safety guidance: the ladder moves, the person overreaches, or the footing gives way. Understanding the failure modes is what separates a safe job from an ER visit.
- Ladder instability. A ladder set at the wrong angle, on soft or uneven ground, or unsecured at the top can kick out or slide. The base should sit about one foot out for every four feet of height.
- Overreaching. Leaning past the ladder rails to avoid repositioning shifts the center of gravity outside the base and tips the whole assembly.
- Lost contact. Carrying tools or materials by hand breaks three-point contact, the single habit most consistently tied to staying on the ladder.
- Slick surfaces. Dew, rain, moss, and loose granules cut traction on both rungs and roof slopes, and account for a large share of warm-season falls.
- Roof-edge and skylight hazards. On the roof itself, unguarded edges and fragile skylights turn a slip into a fall to a lower level, the mechanism behind roughly a third of construction fall deaths.
When DIY roofing crosses from risky to reckless
DIY roof work can be reasonable for low-slope, single-story, dry-weather tasks with fall protection and a spotter, and unreasonable above that line. The federal data does not say never climb a ladder; it says the margin for error is thin and the consequences are physical and permanent. The decision often comes down to slope, height, surface condition, and whether you have real fall protection rather than confidence.
Before starting, weigh the job against the numbers in this report and the practical limits in our guide to roof safety, OSHA rules, and DIY limits. If the plan is a full re-roof, read where the honest stopping points are in our breakdown of DIY roof replacement cost and when to stop, and price the gear that actually prevents these falls in our roofing safety equipment and fall-protection guide. For the professional-side risk picture, our OSHA roofing violations report shows how often fall protection is the failure point even on paid crews.
Methodology and sources
This report synthesizes public federal and peer-reviewed injury data rather than any proprietary survey. Ladder-fall totals and death estimates come from the U.S. Consumer Product Safety Commission and its National Electronic Injury Surveillance System (NEISS). Occupational figures come from the CDC report Occupational Ladder Fall Injuries, United States, 2011, and from the U.S. Bureau of Labor Statistics Census of Fatal Occupational Injuries (2011 to 2024). Long-run injury patterns and the residential-setting share come from Ladder-Related Injuries Treated in Emergency Departments, 1990 to 2005, in the American Journal of Preventive Medicine (2009). Construction fall-source shares come from CPWR analysis of BLS data. The AAOS figure reflects all medically treated ladder injuries, a broader count than ED-only totals. Because no federal system tags injuries as “DIY roofing,” DIY-specific figures are inferred from the documented non-occupational share of ladder-fall injuries and should be read as directional, not precise. Where a figure is an estimate or annual average, it is labeled as such. Last reviewed July 2026.
