TabHow It Works

How Leaf Stopper Works

The LEAF STOPPER® system is a logical approach to practical protection of gutters and valleys. It works by attaching one end of the mesh to the front lip of the gutter, while the other end passes over the first row of tiles and under the second row. This creates a slope which allows leaves to blow off. In the case of metal roofs, purpose manufactured clips hold the mesh down at the roof end and valleys.

A Good Gutter Guard Will Do Three Things Well 

  1. Keep leaves and pests out of your gutters and valleys.
  2. Allow water in.
  3. Increase the chance of leaves coming off (reduces maintenance).

Keeps Leaves and Pests Out of Gutters and Valleys

The advantage of the Leaf Stopper® system is that not only does it protect the gutters, but it prevents leaves and pests entering the valley. Many gutter guard systems sound credible when discussing the gutter, but fail to mention how they plan to protect your valleys. It is well known that leaves will accumulate in the corner valleys of the roof and then make their way down to the gutter. Leaf Stopper® prevents this from happening.

Allows Water In

Over 20 years of experience suggests that an aperture of around 4mm x 4mm is ideal for getting a balance between keeping leaves out and keeping water in. Products that have smaller holes than this could allow water to flow over the top of the gutter guard which is referred to as sheeting. Furthermore, a small hole means that small dust and debris is more likely to clog and even have moss growing on them. This then opens the door to other problems such as dampness where insects can breed.

An additional benefit of Leaf Stopper® is that water starts entering the gutter guard at the top of the first tile. This gives water a chance to enter the mesh and make its way to the gutter.

Leaves Come Off

The more work that Mother Nature can do, the less there is for you to do. Leaves will dry over time and when the wind arrives, they have a greater chance of blowing off. It is a fact that the greater the incline, the more chance the leaves have of coming off by themselves. This is very difficult to achieve with some systems that are inserted into the gutter.

Protects from Pests

Leaf Stopper fully covers your gutters and valleys helping keep your home pest free.


If the holes in the mesh are too large, leaves get stuck on the mesh.  If the holes in the mesh are too small, water sheets off the roof and is not captured by your gutters. Our specially designed mesh ensures leaves blow away, while water is captured by your gutters.

Fire Safe

CSIRO tested. Leaf Stopper will not burn and helps keep your home safe from fire by ensuring flammable leaves do not remain on your roof.

Covers Valleys and Gutters

Don’t just cover your gutters, leaves can also accumulate in your valleys. Systems that ignore valleys can cause leaves to clump at the bottom of each valley.  Leaf Stopper provides the best protection for gutters and valleys.
