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.
Surface temperature vs. air temperature: the number the forecast won't give you
Almost every threshold that decides an outdoor job is a surface threshold — and almost every forecast reports air. Here's how far apart they get, and why the gap is where jobs go wrong.
Ice isn't snow: why the two events need completely different plans
The same storm total can mean an easy plow night or a liability event. Here's why precipitation type — not accumulation — should drive the pre-treat and plow call.
Wind and lifts: the 28 mph limit, and the crane rule everyone gets wrong
Aerial lifts have a real wind rating most crews never check — and the '20 mph OSHA crane limit' people quote isn't what they think it is. Here's what actually binds, and what's just rule of thumb.
Excavation after rain: why the trench you left Friday isn't the trench you return to
OSHA requires a competent-person re-inspection after every rainstorm — and rain can reclassify the soil itself, changing the slope you're legally allowed to work at. Here's what that means for a Monday morning.
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.
