Q: How does wind affect the Leaf Relief System?
  A: The surface of the product is flat, has a smooth finish and is vented both from the bottom and the top. Exposed to the sun, the debris on its surface quickly dry up and become lighter. Wind easily clears the dry leaves, a 10 km/h wind clears the wet leaves and an average 100 pine needles per one foot length and a 37 km/h wind clears an average one inch thick of pine needles per one foot length.
  Q: How does Leaf Relief handle snow?
  A: The Leaf Relief system does not create a source of heat that turns the snow into ice. It does not require roof shingle be lifted to be installed and therefore does not become a potential source of water infiltration. It lowers the weight of the snow sitting in the gutter during winter. It allows the water to flow to the downspout without debris when snow melts (as opposed to having a slushy mix of ice, snow and debris for ages until the water literally evaporates because it can't run to the downspout).
  Q: I have had my gutter system for a long time. Will Leaf Relief still fit my gutters?
  A: Yes, most likely. The Leaf Relief System is designed to fit virtually every type of gutter system.
  Q: How can water enter the gutter? There are not enough holes and they're too small.
  A: Extensive research and development led to our exclusive Alu-Perf´™ technology. The product has 489 perforations every 20 inches. This drains water at the same rate as a 2x3 downspout. Extensive testing proves that Alu-Rex products can drain up to 32.9 inches of rainwater per hour; the highest amount of rainfall ever recorded was 12 inches of water per hour (Holt, MO, 1947).
  Q: Will leaves and debris stick to the Leaf Relief?
  A: Not in most cases. Leaf Relief has a smoothÊfinish which allows removal of leaves and other debris by wind speeds that are normal in most areas.
  Q: WillÊthe Leaf Relief rust?
  A: No. The Leaf Relief is made of aluminium and will never rust.
  Q: My neighbour's rain removal system is very noticeable and unsightly when looking at it. Is Leaf Relief the same way?
  A: No. The Leaf Relief is virtually invisible from the ground.
  Q: How can I be assured that Leaf Relief will last?
  A: The Leaf Relief Product has been tested in accredited labs and have been in service in Canada (under severe weather conditions) for over ten years.
  Q: Is there an Leaf Relief warranty?
  A: The Leaf Relief System is backed by our "Never Clogs, Never Overflows" 10-year warranty.
  Q: Can Leaf Relief withstand heavy water flow?
  A: Even when 100% of the holes are blocked, the system can still carry nearly twice as much water as the heaviest recorded rainstorm. The reason is that wet leaves are "sweating" which means some water still goes through the leaves and then down the holes. The water always finds its way through the holes, plus it has about one quarter of an inch of "guard" in case the water level would rise further before it finds its way through.
