Long Range Weather for Roofing Contractors

"Most people in this extremely weather-sensitive industry would be absolutely delighted to gain even a ten percent edge against the weather."

Optimize your schedule around the weather

Now, when you nail down a new project and begin to layout your schedule, you can look to the dryday™ forecasts to help you minimize unexpected wet weather. With this understanding, you can adjust the most weather-sensitive portion of your schedule to occur during the forecasted drier periods.

The dryday™ Advantage

Over the past ten years, projects planned with dryday™ have enjoyed significant odds on their side with accuracy up to 87%.

Planning on your own puts you at additional risk

During that same time period, dryday™ forecasts outperformed planning on your own by a factor of almost three to one. This means that if you were planning with dryday™ forecasts during that period, roughly three out of four dryday™ forecasts would have provided you better odds over planning on your own.

The opposite is also true, if you were planning on your own, you would have been at a disadvantage around 75% of the time. Without a dryday™ forecast you could be planning projects right in the middle of a period with a high chance of rain (Risky).

What about using other weather forecasts?

  • Media outlets continuously change their 3-10 day forecasts making them unusable for planning.
  • Other long term weather predictions use Climatology (historical averages) to predict the weather. This strategy has proven to be unreliable.
