3 places water can cause problems on a garage exterior: behind the siding, around the windows, and at the roof edge.
That’s why this project uses HydroGap, flashing tape and drip caps around the windows, plus six-inch gutters with 3x4 downspouts. Each detail handles a different part of the same job, controlling where the water goes.
Save this if you’re planning a garage or exterior project.
