It all depends on the amount of rain the size of roof and your ability to store the water. Here is a quick formula to figure out how much rain you might collect on your roof. 1 inch of rain on a 1000 sq ft roof yields 625 gallons of water. To calculate the yield of your roof, multiply the square footage of your roof by 625 and divide by 1000. I hope that helps! Eleanor,
