A roof collapse or other structural failure can make a building dangerous even when the damage looks limited. Get out by a safe route, move well away, and call emergency services from a safe location; do not re-enter or approach the debris to retrieve belongings. Wait for authorities to permit re-entry and, where damage or uncertainty remains, for a qualified inspection.
What should you do first after a roof collapse?
Move people away from the building, call emergency services once you are at a safe distance, and keep others out. A partial roof failure can leave other parts of the structure unstable or create hazards that are difficult to see, including falling material, exposed wiring, gas, fire, and hazardous dust. The absence of visible smoke, an obvious gas odor, or further movement does not establish that the building is safe.

- Leave if you can do so by a safe, accessible route. Do not stop to collect phones, documents, medication, pets, or other possessions. If you are already outside, move away from the building and debris. Follow any evacuation instructions from local authorities.
- Call emergency services from safety. Give the location and say that a roof or structure has collapsed. Report known injuries, people who are missing or believed trapped, and any fire, smoke, gas odor, exposed wires, or other immediate hazards.
- Keep people away. Do not re-enter, walk into debris, climb onto the roof, or let bystanders approach. Do not attempt a rescue, demolition, cleanup, or utility shutoff yourself.
- Follow responders and official updates. Tell responders what you know about occupants and the building, stay clear of access routes, and monitor local alerts or broadcasts. Do not go back inside until authorities direct you to do so.
These are conservative steps drawn from public emergency guidance on building collapses, evacuation, and damaged structures. NYC Emergency Management specifically advises not to re-enter a building or enter a debris field to look for personal property; OSHA’s response and recovery guidance also says to wait for authorities before re-entering. Local instructions govern, and emergency numbers differ by jurisdiction. Call the local emergency number; 911 applies in the U.S. guidance cited here, but it is not universal.
How do you leave without making the situation worse?
Use only a route that appears safe and accessible; do not cross beneath visibly damaged areas or through debris to save time. The guidance does not provide a way for an untrained person to assess a damaged building or identify a structurally safe route from inside, so do not treat a quick look at a ceiling, wall, stairway, or roof as a safety inspection.

If an exit is blocked, the route is visibly damaged, or you cannot leave without entering an unsafe area, do not force your way through the debris. Call emergency services if possible, explain where you are and what is preventing your exit, and follow instructions from responders. If you are outside, move farther away rather than approaching to look inside or help someone in the debris field. Search and rescue should be left to trained personnel.
Do not delay evacuation to turn off utilities, retrieve valuables, or check other rooms. A damaged building can contain energized wiring, gas leaks, shifting debris, or unstable structural elements. The Arizona Department of Homeland Security discusses utility checks in disaster recovery guidance, but that is not a reason for an untrained person to enter a collapse site. Leave utility work to responders or utility professionals unless they give specific instructions and it is safe to follow them.

What should you tell emergency services?
From a safe location, provide the facts that can help responders locate the incident and understand immediate risks. You do not need to diagnose why the roof failed or estimate the structure’s condition.
- The building’s address or clearest available location.
- That a roof or another part of the structure has collapsed or failed.
- Whether anyone is injured, missing, or believed to be trapped, and where they were last known to be if you know.
- Any smoke, flames, gas odor or hissing, exposed wiring, downed power lines, or other hazards you can report without approaching.
- How responders can reach you for additional information, if needed.
Do not enter or move closer to verify a detail. If you are unsure whether someone made it out, say that you are unsure and share what you already know about the person’s last known location. Keep access routes clear and pass information to responders rather than organizing a search yourself.

What if someone is trapped?
Call emergency services if you can do so safely, and do not enter the debris field to attempt a rescue. If you are outside, tell responders where the person is believed to be and what is known about their condition. A second collapse or another hidden hazard can put would-be rescuers at risk as well as the person they are trying to help.
If you are trapped, try to stay calm and remain where rescuers can see or locate you. Avoid unnecessary movement because it can raise dust or disturb debris. If possible, use a flashlight to signal or see your surroundings, tap on a pipe or wall, or use a whistle. Shout only as a last resort because dust may be harmful to inhale. OSHA’s general emergency guidance advises a trapped worker to stay calm, call for help if possible, and remain where rescuers can see them.

Which hazards should make you move farther away?
Any sign of fire, gas, electrical danger, falling material, or further structural movement is a reason to withdraw and alert responders. Do not approach to investigate or try to correct the problem.

- Unstable structure or falling debris: A partial roof loss may leave other parts unstable. Ceilings can sag or fall, and debris can shift. Do not walk on a roof or floor unless its supporting structure has been verified safe by qualified personnel.
- Gas odor or hissing: Leave the affected area and report the hazard from safety to emergency services or the gas utility. Do not use flames, switches, appliances, or electronics in the affected area. Do not go back inside to locate a shutoff.
- Downed lines or exposed wiring: Keep away from wires and from objects touching them. Never touch a line or an object that may be in contact with one; report the danger.
- Smoke or flames: Report fire or smoke immediately. A fire can occur after an explosion, and hazards may persist after the initial event.
- Dust or debris: Avoid stirring up collapse dust or handling debris. It may contain hazardous dust or other contaminants, and moving material can also create additional danger.
These cautions reflect the hazards identified in OSHA’s response and recovery information, NYC Emergency Management’s collapse guidance, and San Mateo County’s safety guidance after a disaster. Do not assume that personal protective equipment, a quiet scene, or a lack of visible damage makes it safe to enter. Avoid the area until responders say otherwise.
When is it safe to go back inside?
Do not re-enter until authorities direct you to do so. If the building has damage or you are uncertain about its integrity, a qualified inspection may also be needed before anyone returns. A quick look from outside cannot confirm that supports, floors, ceilings, or remaining roof sections are sound.
Follow any evacuation order or official restriction even if the damage appears minor or the building seems quiet. Ready.gov’s preparedness guide recommends having damaged homes inspected by a qualified professional and leaving if safety is uncertain. San Mateo County likewise recommends a qualified building inspector or structural engineer when a building’s integrity is in doubt. If officials have marked the property unsafe, stay out until they say the danger has been addressed.
Re-entry is not a decision to make based on whether the roof looks intact from one angle, whether someone has visited the property before, or whether protective gear is available. Do not walk on a roof or floor whose support has not been verified safe. A qualified professional’s inspection and official instructions address different questions: whether the structure has been assessed and whether authorities permit access. Follow both where they apply.

What changes if the failure is only partial?
The immediate response is the same: leave by a safe route, move away, call emergency services if there is an active danger or anyone may be injured or trapped, and keep others out. A small-looking collapse is not proof that the remaining structure is stable. Roof failure can affect connected areas, and falling material, exposed wiring, or gas hazards may not be visible from outside.
If no emergency hazard is apparent, do not convert that absence into a safety clearance. Avoid entering to inspect, walking beneath the damaged area, or climbing onto the roof to assess it. Follow local instructions and seek a qualified inspection when structural integrity is in doubt. The sources address collapse, disaster recovery, and evacuation generally rather than a single roof-failure scenario, so the safe approach is not to infer that a particular type or size of damage is harmless.

- Do not go back inside for possessions, even if they seem close to an exit.
- Do not enter the debris field to search for or rescue someone; tell responders what you know.
- Do not approach downed power lines, exposed wires, smoke, flames, or a suspected gas leak.
- Do not use a flame, switch, appliance, or electronic device in an area where gas is suspected.
- Do not attempt to shut off utilities, move structural debris, or begin cleanup.
- Do not treat a quiet scene, a visual check, or protective equipment as proof the structure is safe.
- Do not return until authorities permit it; arrange qualified assessment when damage or uncertainty warrants it.
The first priority is protecting people, not protecting property or figuring out the cause. Stay at a safe distance, share relevant information with responders, and let trained personnel handle rescue, hazard control, and assessment.
Frequently Asked Questions
Does a partial roof collapse still require an emergency call?
If anyone may be injured or trapped, or there is fire, smoke, a gas odor, exposed wiring, or another immediate danger, call the local emergency number from safety. If the event is over and no immediate hazard is apparent, keep people out and follow local authorities’ instructions about assessment; an apparently calm scene is not a structural clearance.

Should I call 911 after a roof collapse outside the United States?
Use the emergency number for your location. The cited U.S. guidance uses 911, but emergency numbers vary by jurisdiction, so do not assume that number applies everywhere.
Can I take photos of the damage for insurance before leaving?
Do not delay leaving or approach the building to document damage. Personal documentation is not worth entering a debris field or going near an unstable structure; leave the area and follow responder instructions.
