Aluminium Mesh Corro

Keep leaves and animals out

Our 4mm aluminium gutter mesh lowers your risk of clogged gutters and expensive flood and pest-related damage. The mesh helps stop possums and other animals getting into your gutters and roof, and keeps large and medium-sized debris and leaves such as silky oak leaves, gum leaves and gumnuts out of your gutters and downpipes.

Alum Mesh Tiled Roof

Install quickly and easily

Lightweight and flexible, our 4mm aluminium gutter mesh comes in ready-made rolls with all the screws and saddles or clips you need for fast and easy installation. The mesh and componentry is available in 27 COLORBOND® colours to ensure it discreetly blends with your roof and property.

Aluminium Mesh On Roof With Pool

Maintain with ease

By keeping medium and large leaves out of your gutters, our 4mm aluminium mesh significantly reduces the need for regular gutter maintenance around your property. In turn, this lowers the risks associated with working at heights on ladders and roofs – and lowers the cost of hiring someone else to do it.

Benefits of 4mm Aluminium

Blue Mountain Co 4mm Aluminium Gutter Mesh will provide great protection against large and medium foliage.

Blue Mountain Co 4mm Aluminium Gutter Mesh is a bushfire compliant mesh, meaning it is a safe, non-combustible material that can be used in bushfire zones as gutter guard. Note: Only “ember guard compliant” mesh will keep both leaves and embers out of your gutters, providing maximum defence against ember attack. That’s why we recommend our 2mm Steel gutter mesh for all homes in requiring protection against embers. 

Aluminium mesh can provide a good barrier against pests and vermin attempting to enter your roof cavity, preventing wild animals from making your home their home.

Aluminium is an ideal solution for projects where budgets are limited.

This mesh will help with these environment factors:

Keeps out pests & vermin   Keeps out large leaves

Medium strength                    Keeps out medium leaves

 Bushfire compliant

See our installation guides below. For more detailed guides including images and product warranty, download the full document underneath.

  • Corrugated Installation
    1. Place the roll of mesh on the roof. The edge of the mesh should rest on top – and just inside – the gutter edge.
    2.  Roll the mesh out along the gutter edge.
      INSTALLATION TIP: Screw the mesh to the gutter at both ends to hold the mesh in place.
    3. Place the standard or Mesh Lock trim over the mesh. The mesh should rest under and against the front edge of the trim. Secure by placing a metal screw in every pre-made hole. Do not over tighten the metal screws. (INSTALLATION TIP: As a guide, tighten the screw to the point where the rubber washer begins to compress.)
    4.  Create a flap/tag in the mesh to mould it to the corrugation. To do this, cut two slits about 20mm apart and approximately 30mm long over every second rib.
    5.  Place the saddle over the flap/tag and secure using a metal screw. Do not over tighten the metal screws.
      INSTALLATION TIP: As a guide, tighten the screw to the point where the rubber washer begins to compress. For best results, use the mesh as a string line to keep the saddles straight.

    Joining mesh

    When joining two pieces of mesh, overlap the mesh by 20mm. Once it’s in place, insert a metal screw through the centre of the overlap. Fasten until the overlap pulls together.

    Corners

    Cut the mesh to the shape of the ridge capping. Overlap the mesh above the gutter and join using a metal screw.

  • Tiled Installation
    1. Place the roll of mesh on the roof with the edge of the mesh facing the gutter. The edge of the mesh should rest on top – and just inside – the edge of the gutter.
    2. Roll the mesh out along the gutter edge.
      INSTALLATION TIP: Screw the mesh to the gutter at both ends to hold the mesh in place
    3. Place the standard or Mesh Lock trim over the mesh. The mesh should rest under and against the front edge of the trim. Secure by placing a metal screw in every pre-made hole. Do not over tighten the metal screws.
      INSTALLATION TIP: As a guide, tighten the screw to the point where the rubber washer begins to compress.
    4. Using offset tin snips, cut a slit in the back of the mesh next to the overlap in every tile.
    5. Tuck the mesh under the tile by lifting the second row of tiles from under the mesh. Use a flat head screwdriver to lever the second tile up as required.
    6. If the hips and gable ends are secure with concrete, you will be unable to lift the second tile. Instead, cut the mesh to be in line with the front of the second row of tiles and seal with silicone (if required).

    Joining mesh

    When joining two pieces of mesh, overlap the mesh by 20mm.  Place a metal screw through the centre of the overlap.

    Corners

    Cut the mesh around the edge of the ridge capping.  Overlap the mesh above the gutter and join using a metal screw.

  • Trimdek Installation
    1. Place the roll of mesh on the roof with the edge of the mesh facing the gutter. The cut edge of the mesh should rest on top – and just inside – the edge of the gutter.
    2. Roll the mesh out along the gutter edge.
      INSTALLATION TIP: Screw the mesh to the gutter at both ends to hold the mesh in place.
    3. Place the standard or Mesh Lock trim over the mesh. The mesh should rest under and against the front edge of the trim. Secure by placing a metal screw in every pre-made hole. Do not over tighten the metal screws.
      INSTALLATION TIP: As a guide, tighten the screw to the point where the rubber washer begins to compress
    4. Secure the roof edge of the mesh by securing a saddle to every rib. Before installing the saddles, cut a “U” shape in the mesh about 40mm wide and 90mm long at every rib.
    5. Place the saddle over the “U” shape and secure using a metal screw, then place a metal screw at the bottom of the “U” section through the mesh into the top of the rib. Do not over-tighten the metal screws. As a guide, tighten the screw to the point where the rubber washer begins to compress. For best results, use the mesh as a string line to keep the saddles straight.

    Joining mesh

    When joining two pieces of mesh, overlap the mesh by 20mm. Place one metal screw through the centre of the overlap.

    Corners

    Cut the mesh to the shape of the ridge capping. Overlap the mesh above the gutter and join using a metal screw.
  • Valley Installations

    Corrugated:

    1. Roll out the required length of valley mesh along the valley gutter. Valley mesh should be installed last to ensure it sits on top of the gutter mesh at the gutter.
    2. Cut two slits about 20mm apart and 30mm long at the same angle as the corrugation to create a flap/tag at every rib on both sides of the valley.
    3. Secure by placing each saddle on an angle over the flap/tag and secure using a metal screw through the saddle, mesh and into the roof sheet. Do not overtighten the metal screws.

      INSTALLATION TIP: As a guide, tighten the screw to the point where the rubber washer begins to compress.

    Tile Valleys (Aluminium Mesh):

    1. Roll out the required length of gutter mesh along the valley gutter.
      NOTE: Valley mesh should be installed last to ensure it sits on top of the gutter mesh previously installed at the gutter.
    2. Determine two points up the valley where the mesh will transition from over the tile to under the tile (a), and length of the flap which will be tucked under the tile (b), all the way up the valley on each side. Using tin snips trim the excess mesh away where these two points intersect up the valley on each side.
    3. Using tin snips, cut the mesh on either side of the valley using points (a) and (b) as a guide. The notches (approximate thickness of the tile) created at point (a) will allow the mesh to transition from above to below the tile easily.
    4. Using a flat head screw driver, lever the upper tile off the lower tile (1) and then tuck each flap created previously (2) under, before lowering the tile back in place. Press down firmly to lock the mesh into position being careful not to damage the tile.

    Steel Domed Installation:

    1. To fit the domed valley mesh, squeeze the mesh together until the folded edges fit beneath the roof sheet on both sides of the valley. Release the mesh so that it spreads and fits snugly under both edges of the roof.
    2. You may be required to cut your domed valley to match your gutter mesh and ridge profile.
    3. Start fitting the domed valley mesh at the bottom of the valley, 100mm up from the end of the roof sheet where it enters the gutter. Work up to the ridge overlapping each section by 4 mesh squares. The valley mesh should be fitted over the top of the regular gutter mesh at the bottom of the valley.
    4. Secure each overlapping section of valley mesh together using metal screws provided. For narrower valley mesh, one screw per join is sufficient. For wider mesh, use two screws.
    5. Push the dome flat at the top and bottom to close off all openings and secure the overlap with metal screws.

    For tile roofs:

    1. When fitting domed valley mesh to tiled roofs, it is important to have created a uniform gap over the valley gutter or to ensure the correct size domed valley are fitted to the progressive gaps if they change through the length of the valley.
      NOTE: To create and even gap you may need to cut the valley tiles up either side of the valley. Ensure the domed valley ordered is appropriate for the gap created.
  • Maintenance
    Installing gutter mesh will significantly reduce the volume and frequency of maintenance required for your gutters and roof. On sloped roofs, the mesh slope and over-the-gutter design will ensure that most leaves and debris are blown off the roof and mesh by the wind.
    However, no gutter protection system is completely maintenance free, so you will still need to occasionally check and clean your mesh and gutters to remove debris caught on the edge of your mesh or saddles, fine debris that may have collected in your gutters, or leaves and debris that cannot “self-clean” due to your roof slope or gutter type.
    Do not remove gutter mesh to carry out maintenance.
    We recommend engaging a maintenance professional to clean your gutters and mesh as they have the right equipment, experience and training to do so safely. If you choose to maintain your gutters and mesh yourself, take appropriate safety precautions first.
    • Wear protective gloves, protective clothing and protective non-slip footwear.
    • Do not wear loose clothing or jewellery.
    • Keep your work area clean and orderly.
    • Keep children away.
    • When using a ladder, follow the manufacturer’s instructions or seek professional advice.
    • Do not over-reach.
    • Stay alert. Watch what you are doing. Use common sense. If in doubt, seek help before proceeding.
    Use a leaf blower to remove leaves and debris from on top of your roof and gutter mesh.
    If there is any build-up of sediment or fine debris inside your gutters, use a normal pressure hose (through the mesh) to flush it out.
    Keep in mind that gutter mesh on flat roofs and box gutters will require more frequent maintenance, as their location and/or pitch make it difficult for leaves and debris to blow off the roof and mesh. If you have trees that drop large volumes of debris, you may also need to conduct more frequent maintenance. Installing gutter mesh will significantly reduce the volume and frequency of maintenance required for your gutters and roof.

  • Product FAQ's
    • Which gutter mesh should I choose?

    Identifying the ideal mesh or meshes for your property depends on a number of factors, including the types of vegetation around your property, your bushfire risks and whether you live in a hail- or snow-prone area. For assistance selecting the best gutter mesh for your home or building, use our handy Mesh Matcher tool.

    • What does my warranty cover?

    All our gutter mesh materials and componentry come with a 12 year warranty from date of purchase. However, as with all warranties, conditions apply.

    • Can I install aluminium gutter mesh on a COLORBOND® steel roof?

    Yes. Blue Mountain Co aluminium gutter mesh is compatible for use with COLORBOND® steel roofs.

    • Is aluminium mesh bushfire compliant?

    Many gutter mesh products are sold as being “bushfire compliant”. However, it’s important to understand whether the product you’re choosing is only compliant for use as a gutter guard in bushfire-prone areas, or whether it’s also compliant for use as an ember guard.
    While all correctly specified “gutter guard compliant” meshes will keep leaves out of your gutters, only “ember guard compliant” meshes will keep embers out too, providing superior bushfire protection. For a mesh to be ember guard compliant, it must have an aperture of 2mm or less and be made from corrosion-resistant steel, aluminium or bronze (for BAL 12.5, 19 and 29) or corrosion resistant steel or bronze (for BAL 40 and FZ).
    All Blue Mountain Co gutter mesh is compliant for use as a gutter guard in bushfire-prone areas, however, only our 2mm steel mesh is also ember guard compliant.

    • I live in a bushfire-prone area. Which gutter mesh should I choose?

    At Blue Mountain Co, we believe that you should protect yourself against the risk of fires igniting in any area of your property, including your gutters, roof cavities and wall spaces.
    Choosing an ember guard compliant mesh could save lives and property.
    That’s why we recommend our ember guard compliant 2mm corrosion-resistant steel gutter mesh for all homes in bushfire-prone areas.

    • I live in a hail- or snow-prone area. Which gutter mesh should I choose?

    If you live in a hail- or snow-prone area, we recommend choosing a steel gutter mesh product as steel offers superior strength for withstanding the threats posed by the weight of accumulated fallen hail and/or snow.

    • What comes in my gutter mesh kit?

    Our gutter mesh kits are all-inclusive, so they contain everything you need for your chosen installation.

    • Which screws should I use to install my gutter mesh?

    All our gutter mesh comes in all-inclusive kits, including all the metal screws and plastic stitching screws you need for installation. Using other screws will void the warranty on your product. If you run out of screws, contact Blue Mountain Co for additional screws.

    • I’ve run out of saddles. What should I do?

    If you don’t have enough saddles for your installation, contact us and we’ll send you more. Do not use your own saddles as this will void the warranty on your product.

    • Do I need to use trim when installing my mesh?

    Yes. All aluminium gutter mesh comes with trim for installation. Using trim will improve your gutter mesh performance.

    • How often do I need to clean my gutters after installing mesh?

    Installing gutter mesh will significantly reduce the volume and frequency of maintenance required for your gutters and roof. On sloped roofs, the mesh slope and over-the-gutter design will ensure that most leaves and debris are blown off your roof and mesh by the wind.
    However, no gutter protection system is completely maintenance free, so you will still need to occasionally check and clean your mesh and gutters to remove debris caught on the edge of your mesh or profiles, fine debris that may have collected in your gutters, or leaves and debris that cannot “self-clean” due to your roof slope or gutter type.
    Gutter cleaning is a dangerous task so where possible, we recommend getting your gutters professionally cleaned. As gutter mesh significantly reduces your cleaning requirements, the cost will be significantly lower than before you installed a gutter protection system.

    • Where can I find an installer to install my mesh?

    If you want to have your gutter mesh professionally installed, contact Blue Mountain Co and we’ll put you in touch with an installer in your local area.

    • Can I install my gutter mesh myself?

    Installation guides for all our gutter mesh products are available. If you choose to install gutter mesh yourself, be sure to take appropriate safety precautions and thoroughly read the installation guides before commencing installation.
