We get asked about gutter guards constantly. Homeowners see the ads, hear the pitch, "never clean your gutters again!", and want to know whether it's worth the upfront investment. We're going to give you the honest answer, which is more nuanced than either the sales pitch or the outright dismissal you might read elsewhere.
Short version: gutter guards can help, but they won't eliminate the need for maintenance, particularly in Sydney's environment. Here's the full picture.
What types of gutter guard are there?
There are three kinds you will be offered in Sydney. We clean gutters with all of them every week, and we install one of them.
Screw-fixed mesh systems
A metal or plastic mesh screwed to the roof and the gutter edge. This is the expensive one, usually around $1,000 for a single storey and $2,000 for a double. It still needs cleaning, fine mud and gum dust get through it, and it gets torn up over time by whoever cleans the gutters. We do not recommend it and we do not install it.
Sit-in foam or plastic guard
One-metre foam panels or UV-stabilised plastic strips that sit inside the gutter, nothing screwed or glued. Cheap, about $10 a metre plus $150 to $200 to fit, easy to lift out for cleaning and put back. This is the type we install.
Brush guard
A long bristle brush that sits in the gutter. Debris tangles in the bristles instead of blowing off, so it ends up harder to clean than a bare gutter. Not our pick.
One thing to avoid: the roll of mesh from the hardware store that you cut and lay yourself. It flexes, gaps and lets debris underneath, where it is harder to get out.
What gutter guard does well
A guard cuts down how often the gutters need clearing. The big stuff, gum leaves, bark strips and seed pods, stays out of the channel, which is where most blockages start. A well-fitted guard also makes it harder for possums, rats and birds to get into the gutter and roof space.
What gutter guard doesn't do, and the sales pitch won't tell you
It never gets rid of cleaning
Gum dust, fine bark, seed capsules and mud go straight through or build up on top. Over a few seasons a layer of compacted muck sits on the guard and the water can't get past it. Someone still has to go up and clear it. You are not removing the job, you are changing it.
It makes each clean more expensive
A guarded gutter takes longer to clean because every section has to be lifted, cleared underneath and refitted. Our price for a gutter clean goes up 63% with removable guard and 80% with a screw-fixed system. Over a few years, the extra cleaning cost on a screw-fixed system can be more than the system itself.
A clogged guard can make heavy rain worse
When the top of the guard is coated in muck, water sheets straight over the gutter in a downpour and misses it completely. We see this on homes where the guard was sold as storm protection.
Our honest verdict
Worth it if: you have light to moderate tree cover and you want fewer cleans and fewer pests. Go with cheap sit-in guard, fitted properly, and keep a 6-monthly or yearly clean in the diary.
Not worth it if: you are under gum trees, you are looking at a screw-fixed system, or someone has promised you will never clean again. You will pay for the product and still pay for the cleaning, at a higher rate.
