The weather app built for contractors.
DecideWeather turns the forecast into a clear Go / Caution / Stop recommendation for every operation you run — roofing, paving, sealcoating, concrete, general construction, painting, and snow & ice removal — tuned to your exact job site and the conditions that affect whether your crew can work.
Tuned to the work you actually do.
The conditions that stop a roof crew are nothing like the ones that hold a concrete pour or a sealcoat. DecideWeather is built around each operation\u2019s real thresholds — pick your trades and every recommendation is tuned to them.
Roofing
Sustained wind and gust limits, precip timing, and dry-in windows for tear-off and shingle work.
Paving
Mat and surface temperature plus rain timing — the conditions that decide a clean lay-down.
Sealcoating
Surface temperature, dew-point spread, and drying time before the cure window closes.
Concrete
Evaporation rate — wind, humidity, and concrete temperature — for crack-free pours.
General construction
Overlapping windows for framing, sitework, and exterior trades on one shared timeline.
Painting
Dew point and the temperature spread that decide whether an exterior coat actually cures.
Snow & ice removal
Pavement temperature and precip timing for the treat-and-plow window before the freeze.
Other apps report the weather. DecideWeather makes it clear.
A consumer weather app gives you a temperature and a percent chance, then leaves the interpreting to you. DecideWeather resolves the forecast to your exact job site, checks it against each operation\u2019s thresholds, and shows the working window hour by hour — plus real-time alerts and official NWS warnings.
Field notes for contractors.
Reading radar and nowcasts: the next three hours decide the call
A day-ahead forecast sets the plan, but the next three hours decide whether your crew works right now. Here's how radar and nowcasting sharpen a same-day Go / Caution / Stop.
Watch, warning, advisory: what each NWS alert means for your crew
NWS watches, warnings, and advisories aren't interchangeable. Here's what each one actually signals for an outdoor crew — and how to fold them into a work-window decision.
Snow and ice removal: timing the treat-and-plow window before the freeze
Pre-treat too early and it's wasted; too late and the bond sets. Here's how pavement temperature, timing, and precip type define the snow and ice removal window.
General construction: stacking weather windows across every trade on site
A job site rarely runs one operation. Here's how to read overlapping weather windows for framing, sitework, and exterior trades — so the whole site moves together.
Weather software for contractors, answered.
Is there a weather app for contractors?
Yes. DecideWeather is built for outdoor contractors — roofing, paving, sealcoating, concrete, general construction, painting, and snow & ice removal. It turns the forecast into a Go / Caution / Stop recommendation and an hour-by-hour work window for each operation, tuned to your exact job site.
Which trades does DecideWeather support?
Roofing, paving, sealcoating, concrete, general construction, exterior painting, and snow & ice removal — each with thresholds tuned to that operation, from roofing wind limits to concrete evaporation rate to sealcoat drying time.
How is it different from a regular weather app?
Consumer weather apps report temperature and a percent chance of rain. DecideWeather checks the forecast against the specific thresholds that matter for your operation and shows a clear recommendation and work window for your job site.
Does it work on iPhone and Android?
Yes. DecideWeather is a web app (PWA) you install on your phone’s home screen on iPhone, Android, or desktop, with a 2-week free trial — no app store needed.
