Use case
Get a roofer to call when heavy rain forecast
A roofer has patched a leak but you want them to check back when the next downpour is expected, in case the repair fails under heavy rain. You need someone to monitor the weather forecast and call you when conditions match, without you checking daily.
Use one Nexy thread for one agreement: You will call me when heavy rain is forecast in the next two days. The other person receives a message in the chat they already use, without installing anything or creating an account; reminders stop for a task that is already done.

What it looks like
YouCan you call me when heavy rain is forecast in the next two days? I want to know before the storm hits so I can ask you to come urgently if the leak starts again.
ThemYes, I will call you when heavy rain is forecast in the next two days. I will let you know as soon as I see it coming.
NexyOne agreement: You will call me when heavy rain is forecast in the next two days.
ThemI am calling because heavy rain is forecast for tomorrow afternoon. Do you want me to come and check the repair before it arrives?
NexyDone. There will be no more reminders for this completed task.
An example of people making one clear agreement and confirming when it is done.
How to do it
- Start one Nexy thread for the agreement. Agree with the roofer what counts as heavy rain—for example, sustained downpour for three hours or more, or a weather warning issued for your area.
- Decide how much notice you want—one day, two days, or the morning of the forecast rain—so you have time to arrange a visit or move belongings away from the leak. The other person receives a message in the chat they already use and needs no new account.
- Confirm who will check the forecast: the roofer, their office receptionist, or a family member who has offered to help monitor conditions.
- Agree how they will contact you: by phone call, text message with the forecast details, or a voice message if you do not answer immediately. A reminder is most useful while you could still act, usually the evening before.
- Discuss what happens if the forecast changes after the first call—whether they call again to update you, or you take responsibility for rechecking once alerted. Once the task is done, there are no more reminders for that completed task.
Why it works
Where it stops
Keep the agreement narrow and let the people involved make the decisions.
Questions people ask
What if the forecast changes after the roofer calls?
Agree in advance whether the roofer calls again with an update, or whether you take over once alerted. Some people prefer one early warning and then recheck the forecast themselves. Others want a second call if heavy rain moves forward or back by a day. Decide who monitors changes and who stays responsible for the final decision to arrange a visit. Write down what you agreed so both people remember the same thing when the weather shifts.
How do I define heavy rain clearly enough?
Use measurable terms everyone understands: sustained downpour for at least three hours, a named weather warning from the meteorological office, or forecast rainfall above a specific amount like twenty millimetres. Avoid vague phrases like bad weather or a storm, because people interpret those differently. If you live in an area with regular drizzle, specify the intensity or duration that worries you. Agree the threshold in the same conversation where you arrange the callback, so the roofer knows exactly what to watch for.
What if the roofer forgets to check the forecast?
Ask them to nominate a backup—an office colleague, family member, or business partner who can take over if they are on another job or away. Some tradespeople share the task with a receptionist who already monitors schedules and can watch the weather at the same time. Agree who holds final responsibility and get a name for the backup person. If the arrangement depends entirely on one busy individual, consider asking a friend or neighbour to check the forecast as well and text you independently.
How far ahead should the roofer call?
Decide based on how quickly you can arrange their visit and move belongings if needed. One day's notice suits most people: enough time to clear the attic or move furniture, but not so early that the forecast changes completely. If the roofer has a full schedule, ask for two days so they can shuffle other jobs. If you only need to put a bucket down, the morning of the rain may be enough. Discuss your circumstances and their availability, then agree a specific window in the same conversation.
What if heavy rain is forecast every few days?
Agree upfront whether the roofer calls every time, or only for the first forecast after the repair. Some people want one alert to see if the leak returns, then handle future storms themselves. Others need repeated warnings while they save money for a full replacement. Clarify how many callbacks you expect and when the arrangement ends—after one storm, after a month, or when you confirm the repair is holding. Update the agreement if your needs change or the leak proves more stubborn than expected.
Can someone else check the forecast on my behalf?
Yes, if you prefer not to rely on the tradesperson alone. A family member, neighbour, or friend can monitor the weather and call you when heavy rain appears imminent. Give them the same threshold definition—three-hour downpour, twenty millimetres, or a warning—and confirm they have your number and the roofer's contact details. Some people set up two watchers so they get alerted even if one person forgets. Agree who contacts the roofer directly if you are unavailable when the rain approaches.
What counts as completion of this arrangement?
Completion happens when the agreed callback is made: the roofer calls to say heavy rain is forecast, gives you the timing, and asks if you want them to visit before it arrives. The arrangement ends there unless you agreed multiple alerts. If no heavy rain appears within the agreed period—say, two weeks—some people close the arrangement anyway and start fresh if another leak worry arises later. Confirm whether the roofer should call to say no rain is coming, or simply do nothing unless the threshold is met.
What if I am away when the roofer calls?
Nominate someone else to receive the call and make decisions on your behalf—a housemate, family member, or keyholder who can let the roofer in if needed. Give that person the same information: what the repair was, where the leak appears, and whether to arrange an urgent visit or just move belongings. Tell the roofer in advance who might answer and confirm that person has authority to agree a visit. If nobody is home and the leak is serious, agree whether the roofer leaves a message or tries again an hour later.

A recording session depends on whether the engineer is available, but they cannot confirm until the morning of the session itself. Everyone involved needs to know as soon as possible whether the session is going ahead so they can travel to the studio or make other plans.
- Agree who submits a group application before the closing date
A group application needs one person to gather materials and submit everything by a published deadline. If no one takes responsibility, the opportunity closes.
