Just as wet leaves may temporarily adhere to the hood of your car, leaves and debris that land on the surface of Alu-Rex eavestrough leaf guards will dry quickly. And unlike your car hood, the perforated surface of your leaf guard ensures they will dry even faster! Wet leaves are still permeable to water. This means that water can infiltrate between the leaves and even through them and run into the rain gutter. Water can always find a way through the perforations. As shown in independent tests, dry leaves and debris will be easily swept away by a little wind:
- A 10 km/h wind effectively removes wet leaves and some 100 pine needles per linear foot.
- A 37 km/h wind can remove one inch (2.5 cm) of pine needles per linear foot.
