The Inner West has mature street trees and small roofs, which is a difficult combination for guttering. The gutters on a terrace or a worker’s cottage are narrow, the falls are short, and a good part of the drainage runs between roof planes rather than around the outside. It does not take a full autumn to block one. Guard keeps the bulk of the leaf litter out and cuts how often somebody has to be on the roof, which counts for more here than usual because access is often through a neighbour’s property.
The gutter is emptied and checked for rust holes and sagging before any guard goes over it. Guard on a failing gutter only hides the problem.
Terrace and cottage gutters are often original and not a standard modern profile, so the guard is measured to what is actually on the house.
On slate and old terracotta the fixing method matters more than the product. We pick the one that does not break the roof.
The runs between roof planes are the ones that put water inside the house, so those are done first.
Outlets on an old terrace are small and block easily, so they get checked while we are up there.
There is nowhere to leave rubbish on a terrace block, so the offcuts leave with us.
Call 0452 223 327 or send the form with your address and the age of the house if you know it.
We measure the runs, check the roof material and the access, and price it.
We clear the gutters, fit the guard and check the outlets and the finished runs.
Monkeys Roofing installs gutter guard across the Inner West and the rest of Sydney, on terraces, semis, cottages and renovated homes. What the roof is made of and how we reach it are decided on site.
Usually, but it depends on the gutter profile and the roof material. On slate and old terracotta the fixing method matters more than the product, and if something would risk damaging the roof we will tell you rather than fit it anyway.
It keeps leaf litter out of them, which is where most of the trouble starts. It does not change how they are built, so they still need looking at from time to time.
Less often, and that is the point of it. Fine grit still gets through, so a check is still worth doing, particularly before the wet season.
If clearing the gutters is a twice-a-year job on a roof that is awkward to reach, guard is worth pricing. Call 0452 223 327 or send the form for a free on-site quote.

Australian standards and Code requirements we work to, with the source for each.
Observatory Hill has averaged around 1,213 mm of rain a year on records kept since 1858. A 150 square metre roof therefore sends roughly 180,000 litres a year through its gutters and downpipes, which is why a blockage shows up as overflow so quickly.
A valley gutter must be laid at more than 12.5 degrees, with at least 15 mm of freeboard and side angles of 12.5 degrees or more. Below 12.5 degrees it has to be designed as a box gutter to AS/NZS 3500.3 instead, which is a different job with different flashing.
The Code requires downpipes to sit as close as practical to where valley gutters discharge. On roofs with several valleys feeding one length of gutter, a downpipe in the wrong position overloads that section long before the rest of the run fills.

Quoting gutter guard installation in the Inner West is not the same job as quoting it elsewhere in Sydney. Ordinary storms flood thousands of homes here: The Marrickville Valley flood study found 3,989 properties taking more than 150mm of water in a 1 per cent storm, and 3,151 properties still flooded to… That is the kind of detail that changes the materials, the timing and the paperwork on a roof in Haberfield or the streets around it. Everything below links to the council or standard it comes from, so you can check it yourself.
The Marrickville Valley flood study found 3,989 properties taking more than 150mm of water in a 1 per cent storm, and 3,151 properties still flooded to that depth in a storm as common as a 2 year event. Flat ground and slow drainage are the cause, so undersized downpipes and blocked gutters bite in ordinary rain.

Where your roof water is discharged, and whether it is piped properly to the kerb, matters more than how close you are to a watercourse.

Source: Marrickville DCP 2011, section 2.25Any tree 4 metres or taller is a prescribed tree in the Inner West, and pruning more than 10 per cent of its canopy needs a permit, or a full application if the property is heritage listed. Clearing a gutter by lopping a neighbours branch is exactly that situation.

Both shed leaf and bark year round, so gutters here fill slowly and constantly rather than in one seasonal drop.
