Gutter Gauges

The gauge, or thickness, of the gutter will largely determine its overall durability. Gutters usually come in one of three levels of thickness—light, medium, and heavy. Lightweight coil is .025 gauge and, though inexpensive, will often bow between anchor points and is easily damaged by the errant basketball or ladder. Medium-weight coil is .027 gauge—standard for most purposes. Heavy-weight coil is .032 gauge and provides maximum strength and durability.
