Everything useful in the first hour happens indoors
With a roof leaking during a storm, what to do comes down to four things, and none of them involves the roof: make the area safe, contain the water, protect what is beneath it, and photograph everything before you clean up. The roof itself, including any emergency roof tarp, waits until the weather clears.
That is not caution for its own sake. Nothing you could do on a wet roof in a monsoon storm would stop the leak, and the attempt is how people get seriously hurt. Even an emergency roof tarp is something to arrange rather than attempt. The repair is a separate job on a separate day.
This article covers the order to do things in, the two safety points that come before everything else, and what to have ready for the conversation with your insurer afterwards.
Electrical risk comes before water damage
Water and electricity together are the one genuinely dangerous part of an indoor leak, and dealing with them comes first regardless of what else is being ruined in the meantime. If water is anywhere near light fittings, ceiling fans, sockets or a consumer unit, treat the whole area as live until you know otherwise.
Switch off the circuit at the breaker if you can reach it safely and dryly, and keep people out of the room if you cannot. Do not stand in water to operate anything electrical, and do not use a metal ladder near a wet fitting.
If water has reached wiring or a fitting, that is an electrician’s job before it is a roofer’s. Nothing about the roof repair is urgent enough to come before this.
A sagging ceiling is holding water
A ceiling that is bulging, sagging or visibly heavy is carrying a load of water it was never designed for, and it can come down suddenly and without much warning. Drywall that has absorbed water is far heavier than it looks, and the failure tends to be all at once rather than gradual.
Keep people and pets out from underneath it and move what you can from the room. Do not stand under it to inspect it, and do not put a ladder under it to get a closer look at the stain.
You will see advice elsewhere about piercing a bulge to release the water in a controlled way. That is a judgement call made standing directly beneath a failing ceiling, and we are not going to tell you to do it from here. If the ceiling is sagging, treat it as a reason to call someone rather than a task to attempt.
Contain the water and protect what is below
Once the area is safe, the work is ordinary and useful. Buckets or bins under active drips, towels around them to stop splash, and a larger container swapped before it overflows rather than after. Plastic sheeting over furniture that cannot be moved.
Move electronics, documents, soft furnishings and anything of sentimental value out of the room entirely rather than covering them in place. Water travels along ceilings and finds new exit points, so the drip you are catching may not be the only one by morning.
Lift rugs and get them out. Carpet that stays wet is one of the things most likely to become a mould problem later, and mould and rot arising from water damage are typically excluded from cover under 2015 Arizona Department of Insurance guidance.
Photograph everything before you clean up
This is the part people skip and later wish they had not. Photograph or film the active leak, the containers catching it, the ceiling, the walls, the floor and every damaged item, with the date recorded, before anything is moved or mopped.
The 2015 Arizona guidance, from the department now part of DIFI, says exactly this: document damage with photographs or video, and contact your insurer before repairing or disposing of anything. Evidence gathered during the event is worth far more than a description afterwards.
Tie it to the weather. The National Weather Service office in Phoenix defines the monsoon season as June 15 through September 30 and names damaging winds, torrential rainfall, lightning and dust storms among its hazards (NWS Phoenix). A dated storm on record turns your leak into an event rather than an assertion.
Whether any of it is covered is a separate question with its own answer. Will insurance cover a roof leak? covers where the line sits between storm damage and wear.
Nobody goes on the roof during a storm
This is the firmest point on the page and the one we would keep if everything else were cut. A wet tile roof in high wind is brittle, slippery and at height all at once, and the City of Scottsdale’s own homeowner guide says roof work can be dangerous and lethal for the inexperienced.
Lightning makes it worse rather than merely adding to it. The National Weather Service names frequent lightning among monsoon hazards, and a roof is the highest point on the property with a person standing on it.
The NOAA Storm Events Database records 659 thunderstorm wind reports in Maricopa County across the decade to 2025, alongside 450 flash flood reports (NOAA NCEI). These storms are not gentle, and they do not last long enough to justify the risk of getting ahead of them.
An emergency roof tarp is arranged, not attempted
Your policy may require you to take reasonable steps to prevent further damage, and the 2015 Arizona guidance gives putting a tarp on the roof as its example. That is a real obligation and it is worth knowing about in advance.
It is also not a homeowner job. A tarp fitted badly in wind becomes a sail, and fitting one means being on a wet roof in exactly the conditions described above. The way to meet that obligation is to arrange it with a contractor, promptly.
Call during the storm rather than after it if you want someone out quickly, because everyone else in the Valley will be calling the same evening. Ask what can be done temporarily and when, and keep a record of the call as part of your documentation.
The stain is not above the hole
This is worth knowing while you are standing there looking at the ceiling and trying to work out what has happened above it. Water entering a roof travels along battens, rafters and the underside of the deck before it finds somewhere to drop, so the leak can appear a long way from where the water actually got in.
That is why a diagnosis made from inside, during a storm, is unreliable, and why nobody can tell you what is wrong from a photograph of a ceiling. It is also why a roof that leaks in one spot may have a defect somewhere else entirely.

Flats, condos and shared roofs
If you do not own the whole roof, everything above still applies but the reporting obligations do not stop at your own front door. Notify the association or the management company while the leak is still active, in writing rather than by phone alone, and keep that notification with your photographs.
The roof is often common element maintained by the association while the ceiling below it is yours, so the two halves of the same problem can have different owners and different insurers. Delay in reporting is the thing most likely to complicate that later.

Once the weather has cleared
Everything from this point on is aftermath rather than emergency, and it is covered in full elsewhere rather than repeated here. Our existing guide to monsoon roof damage in Scottsdale walks through that period properly: what to check, what to document and in what order.
The short version is that the roof gets inspected by someone who goes up and looks properly, the findings go in writing, and the repair follows from that rather than from a theory formed during the storm.
Keep every container, photograph and note from the night. It is the only record of what actually happened, and once it is cleaned up it cannot be recreated.
One practical thing to do the following morning, before anyone starts cleaning, is to write down the sequence while it is fresh: what time the leak started, where it appeared first, where it spread to, and what the weather was doing at each point. That narrative is often more useful to a roofer than the photographs, because it tells them how the water moved.
Preventing the next one
Most storm leaks are not really caused by the storm at all, which is the most useful thing to take away once the immediate mess is dealt with. They are caused by something that was already wrong and that ordinary weather never tested, which is why the same roofs leak every monsoon while their neighbours stay dry.
Clearing drainage before the season, replacing perished pipe boots and having the underlayment assessed are the three things that remove most of this category of problem. None of them is expensive relative to one emergency callout and a ruined ceiling, and all three can be scheduled at a time that suits you rather than at two in the morning in August. Our guide to protecting a Scottsdale home from monsoon and heat covers the full pre-season picture.

Frequently asked questions
These are the questions people in this area ask most often while a leak is actually happening, which is the worst possible time to be reading anything. Each answer is kept short deliberately, with a link to the detailed article where one exists.
What should I do first when my roof leaks in a storm?
Make the area electrically safe, keep people clear of any sagging ceiling, then contain the water and move what can be damaged. Photograph everything before you clean up. The roof itself is dealt with after the weather clears, not during it.
Can I put a tarp on my roof myself during a storm?
No. A wet roof in wind is dangerous, tile breaks underfoot, and a badly fitted tarp becomes a sail. Your policy may require steps to prevent further damage, and the way to meet that is to arrange tarping with a contractor rather than attempt it.
Should I poke a hole in a bulging ceiling to let the water out?
We will not advise that, because it means standing under a ceiling that is already failing. Keep people out from underneath, move what you can from the room, and treat a sagging ceiling as a reason to call someone rather than a task to take on.
Do I need to call my insurer straight away?
Contact them before repairing or disposing of anything, which is what 2015 Arizona Department of Insurance guidance advises. Document the damage with photographs or video first. Confirm the detail with your own insurer, because policies differ and that guidance is dated.
Why is the leak coming in nowhere near the damaged area?
Because water travels before it drops, running along battens, rafters and the underside of the deck until it finds a path downward. That is why the stain can be several feet from the entry point and why inside-only diagnosis during a storm is unreliable.
How quickly can a roofer come out during the monsoon?
Expect demand to be heavy on a storm night, since everyone affected calls at once. Calling early rather than waiting until morning usually helps, and asking what temporary measures are possible is more productive than asking for a permanent repair in the rain.
