How it works
This is how RainTact calculates how much rainwater your roof can collect.
Enter your address or coordinates
Type in the address of the location you want to calculate. RainTact uses the location to find the right precipitation data.
We fetch the precipitation data
We use historical precipitation data for your exact location. That gives a result adapted to your conditions.
Choose roof area and roof material
Enter how large the roof area is in square feet and which roof material you have. This affects how much rainwater you can collect.
You get your rainwater report
RainTact calculates how many gallons of rainwater the roof can collect per year and per month. The result is shown in a clear report.
