Gutter Guards

Why Are They Important?

Roof gutters are essential to manage and drain rainwater. They also let you harvest rainwater and utilise it fruitfully. However, a common problem with roof gutters is that they become clogged with leaves and other forms of debris. When this happens, rainwater can’t flow properly and the gutters overflow. This can result in damage to the roofing and walls, growth of mould and weeds due to perennial moisture in the gutters, and a range of other problems.

Gutter guards, also known as leaf guards, offer a handy solution to these problems. The basic purpose of a gutter guard is to keep your roof gutters clean and the water flowing. Gutter guards achieve this by covering the gutters and preventing the entry of different forms of debris into the guttering. They are available in a variety of shapes, sizes and types. Here is a look at some of the key benefits offered by gutter guards. Also included in this guide are the leading gutter guard brands and products as well as general estimates on the costs involved.

Benefits of Gutter Guards for Roof Plumbing Systems

Increase Home Value: Gutter guards add some value to your property. A new homeowner will appreciate the fact that there is no need to clear the gutters on a routine basis. Gutter guards also add an element of aesthetics to the roof by covering up guttering in a classy manner. To make the most out of a gutter guard, make sure you choose one that complements the roof type, colour and architecture.

Prevent Mold Damage: Leaves and other debris can clog up an over roof gutter. This in turn leads to moisture and encourage mold to grow not just in the gutter but in the adjoining areas such as ceilings and walls. This can necessitate expensive repairs down the road.

No Need for Maintenance: Clearing up clogged gutters and removing debris on a routine basis is quite a hassle. With gutter guards, you very rarely have to perform gutter cleaning or maintenance.

Avoid Flooded Basements: Clogged roof gutters can lead to flooded basements. Gutter guards ensure better management of rainwater and prevent such this.

Fire Protection: Many gutters guards offer excellent ember protection. They achieve this by blocking out embers with a fine mesh structure. This makes them particularly beneficial in areas with high bushfire risk.

Prevent Ice Dams: When water is not properly drained from a roof gutter, ice dams may build up. These can deteriorate the quality of indoor heating while also creating problems for your roof and adjoining structures. Gutter guards prevent the formation of ice dams by making sure that rainwater keeps flowing through the guttering.

Gutter Guards

Types & Systems

Different types of gutter guards are typically used by homeowners to safeguard roof gutters against leaves and other forms of debris. You will need to consider the pros and cons of each when wondering ‘what is the best gutter leaf guard for your roof.’ Here is a look at these types.

  • Foam Gutter Guards: Foam gutter guards, as the name suggests, make use of long pieces of foam. The foam strips are cut in triangular shape and then adjusted inside a roof gutter. Water passes through the foam while other types of debris such as leaves and twigs are blocked. Foam guards offer a good short-term solution but they may not be very effective in the long-term. In fact, foam gutter guards typically last between 1 to 2 years, after which they will require replacing.
  • Mesh Gutter Guards: Mesh guards are one of the more popular and reliable types. This type of gutter guard comes with tiny holes on every square inch. The holes draw in the water from the roof while effectively keeping out the debris. Mesh gutter guards are typically quite durable and versatile, so that they can be used on a variety of roof types. This is why they are commonly seen on Australian roofs. Unlike foam guards, you will not need to have mesh guards replaced for many long years. However, this type of gutter guards will cost you more at the time of installation.
  • Bottle Brush Gutter Guards: This type, as the name suggests, utilises wire cleaning brushes, also known as bottle brushes. To install this type of gutter guard, all you need to do is purchase the bottle brush pieces and place them install the roof gutter. Much like foam guards, bottle brush guards are able to keep our large pieces of debris. They also take up less space which allows air to circulate through the roof gutter and dry water more readily. Bottle brush guards can work great for a long time – for maintenance, you simply need to take them out and shake off the debris before placing them back again. Although very affordable and DIY-friendly, a slight downside to these is that they are very light-weight and can be blown away in strong wind conditions. Bottle brush guards may also fail to prevent the growth of weed.
  • Screen Gutter Guards: Another widely used type of gutter guard systems is the screen gutter guard. This type of gutter guard is popularly preferred by homeowners across Australia. This is because a screen guard offers many benefits with few downsides. Screen guards come constructed from both metal and plastic. Plastic is typically preferable as it doesn’t rust, although it is lighter and more likely to blow away in strong winds. Screen guards are quite affordable and effective in keeping out most types of debris.
  • Reverse Curve Gutter Guards: Reverse curve guards have been in use for more than a century. This type of gutter guard sits on top of your roof gutter, looking almost like an inverted gutter. It can keep off large pieces of debris although it is ineffective in draining water very well. Installing a reverse guard is quite technical and not even all guard contractors are adept in installing it right.

Gutter Guard Costs

If you decide to use a gutter guard at your home and wonder ‘how much does leaf guard cost per foot’, the answer is: it depends. For per foot or per meter costs, it depends entirely on the type of gutter guard material and profile you are going to use.

If you are going to use a bottle brush or foam guard, it is going to cost you a lot less. In contrast, more permanent varieties like mesh guards and screen guards are going to cost more.

For overall costs, you will have to factor in the length of the area that needs to be covered. Here is a general estimate of the costs involved with different types of gutters:

  • When using a foam guard, you simply need to get a foam guard and insert it into the gutter. A piece of foam cut for this purpose costs around $4 per foot or $13 per meter. To cover the entire length of gutters in an average sized home, you will need about $350 worth of the foam to get the job done.
  • A bottle brush guard is another low-cost solution. It costs around $8 per meter or around $2.5 per foot. For an average home, the total costs of covering all gutters with bottle brush guard sits at around $400 to $500.
  • Mesh guards typically cost more. They can range anywhere from $7 to $30 per meter depending upon the type of profile and quality of material you use. You can choose from metal or vinyl mesh guards. Vinyl mesh guards cost more and you will spend around $800 when using them to cover gutters in an average-sized home.
  • Integrated mesh guard are another commonly used gutter solution. This type of gutter guard costs on the higher-end side of the mesh guards. You can expect to spend $1,000 or above for a typical home when using an integrated mesh guard.

The costs above pertain only to the material costs of different types of gutter guards. If you are going to take a DIY approach to installation, you need not spend any money on installation. However, it may not be practically possible to handle a more advanced type of gutter guard installation, such as that of a mesh guard, on your own. For this, you will need to hire a professional contractor and pay in lieu of the labour costs.

Installation costs will depend on a number of factors. These include:

  • The Roof Pitch. The roof pitch is how flat or inclined your roof is. If the roof is fairly flat, installation of the gutter guards is easy and quick. For more inclined roof profiles, access is going to be harder and specialised equipment may need to be used. This will result in a more time-consuming installation process.
  • Size of Roof. The size of your roof will naturally factor into the total bill of installation. The larger the roof is, the longer it is going to take a professional to install the gutter guard, incurring more costs. For an average Australian home, the total length of gutters that need to be covered is around 50 to 70 meters.
  • Type of Roof. Whether you have a tiled or metal roof can also play a role in determining the overall installation costs for a gutter guard.
  • Roof Profile. If your roof has a fairly plain profile with few valleys and hips, the installation will require fewer cuts and adjustments. For a roof with a lot of valleys and hips, there will be many more adjustments and the installation costs will be higher.

Ultimately, you will need to consider all these factors when determining the costs involved with gutter guard installation. On average, if you have a home with gutters running the length of

around 60 meters or 200 feet, you can expect to spend around $1,500 to $2,000 on gutter guard material costs and installation. If you do the installation on your own, the total costs may come down to less than $1,000.

An exception here is the more high-end gutter guard brands which may come with a price tag of $30 per meter of even $65 per meter. Total material and installation costs for these high-end solutions can be as high as $3,000 to $5,000.
