Emergency Roofing
Get everyone out from under the damaged area first, and keep them out. A ceiling holding water sags before it falls, and then it falls all at once. If water is near light fittings, ceiling fans or wiring, shut off power to that part of the building at the breaker — but only if the panel is dry and you can reach it without standing in water. If the panel is wet or water is pooled in front of it, leave it alone and call an electrician or the utility to cut power from outside. And do not climb up to look. Decking that has been soaked or struck can give way under a foot, and a great many storm injuries happen in the calm afterwards rather than during the weather itself. The National Weather Service's severe thunderstorm safety pages cover the aftermath hazards worth respecting: downed lines, standing water, unstable structures.
What you can usefully do before a crew arrives
Water damage compounds by the hour, and the first hour is the cheapest one to act in. Move furniture, electronics and paper out of the room. Put containers under active drips and empty them before they overflow. If a ceiling is visibly bulging, one small hole punched at the low point with a broom handle — from a safe distance, standing to the side — drains that pocket in a controlled way instead of letting the whole panel let go at once. Open interior doors so air keeps moving. None of this fixes the roof, and none of it is worth taking a risk for, but all of it reduces what has to be replaced later.
Photograph everything before anything is touched
This is the step people skip and regret. Take pictures and short videos from inside and from the ground outside, with timestamps intact, before any cleanup or temporary cover goes on. Record the room, the ceiling, the walls, the contents and whatever is visible outside. Keep receipts for tarps, fans, dehumidifier hire and hotel nights. Insurers reconstruct events from documentation, and a temporary repair that hides the original damage makes an honest claim harder to prove than it should be. Ten minutes with a phone is worth more later than any argument you can make from memory.
What emergency response actually involves
Closing the building envelope, and not much more than that. In practice: mechanically fastened tarps run over the damaged area and lapped so water sheds rather than pools, boarding over openings where material is gone, clearing debris that is holding water on the surface, and removing any limb still bearing on the structure. The attic or interior deck gets checked for how far the water travelled, because the wet area is almost always considerably larger than the hole. Temporary protection is honest work with a real and stated limit: it buys weeks, not seasons, and it should be priced and documented separately from the permanent repair that follows. Ask for that separation in writing, because most policies treat reasonable emergency mitigation differently from permanent repair, and a single blended invoice makes both harder to settle. One hard hour of weather produces a long queue of buildings needing to be made safe, so call as soon as you safely can and describe what you can see from the ground. That description is usually enough to place you in the right order.
