🏠💧 Downspout Drainage: How to Keep Roof Water Away From Your Foundation Did you know that 1 inch of rain on just 1,000 sq ft of roof equals about 623 gallons of water? 😱 If your downspout dumps that beside your foundation, your gutter is delivering the water to the worst possible place. In this video, we follow the water from roof → gutter → downspout → outlet → grade → destination and show how to test your system with simple tools before spending money on a big drainage project. 🔧 ✅ The simple math behind roof runoff ✅ Why distance without proper grade can fool you ✅ Surface extensions vs. buried pipes vs. rain barrels vs. swales ✅ The garden hose trace and storm check ✅ A priority order for fixing several problems at once ✅ A four-level decision tree so you know when to call a pro 📚 Mentioned in the video: Penn State Extension and University of Georgia Cooperative Extension (6 to 10 ft benchmark), plus the IRC grading guideline of a 6 in fall across the first 10 ft. ⚠️ This video is for educational purposes only.
