Much of the peninsula is a surf marine environment. BlueScope names Manly Beach as its metropolitan example of that class, the harshest of its three salt classes under AS 4312, and gutters, brackets and fixings are where that salt shows first. A steel gutter on the ocean strip can rust through at the joints and stop ends while the roof above still looks fine.
Away from the beaches, through Frenchs Forest, Belrose and Terrey Hills, the load is leaf and rain. Terrey Hills averages 1,216mm of rain a year with a sharp autumn peak, so a gutter with a failed joint or a sagging run gets found out in the first heavy downpour. We look at the whole run and tell you straight up whether it can be repaired or needs replacing.
Joints, stop ends and corners that drip are cleaned back and resealed, or remade where sealant alone will not hold.
Small rust holes are patched. Where salt has thinned a whole length, we say so and quote that section instead of patching it twice.
Loose or corroded brackets are refixed so the gutter falls to the outlet and copes with autumn downpours.
We check every outlet and downpipe connection, because a blocked or broken outlet makes a sound gutter overflow.
You get photos of the problem and the finished repair, including the parts you cannot see from the ground.
If a run is past repair we say so and explain why, instead of selling a fix that will fail again next winter.

We look at the gutters and give you a fixed price for the repair before any work starts.
We make the repair, run water through the gutter to check it, and send through the photos.
Monkeys Roofing repairs gutters across the Northern Beaches, from Manly, Freshwater and Dee Why up to Mona Vale, Avalon and Palm Beach, and inland through Frenchs Forest and Belrose.
Sometimes. A few rust holes in a sound run can be patched, but on homes close to the surf salt often thins the whole length, and patching then only moves the leak along. We tell you which one it is before quoting.
If it overflows straight after a clean, the problem is usually the fall, a sagging bracket or a blocked or undersized outlet, not debris. Those are repair jobs, and fixing them is what stops the overflow in an autumn downpour.
Yes. On Northern Beaches Council bush fire prone land, a gutter that holds leaf litter is a fire risk as well as a leak risk, so a repair that restores the fall and keeps the gutter draining also helps keep it clear before summer.
A leaking gutter left through one more storm can rot a fascia or stain a ceiling. Call Vinnie and the local team on 0478 688 951 or send the form to get a free quote, from Manly up to Palm Beach.

Australian standards and Code requirements we work to, with the source for each.
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.
The National Construction Code allows a single downpipe to serve no more than 12 metres of eaves gutter. Long unbroken runs on Sydney terraces and wide Federation frontages often sit over that limit, which is why they overflow in heavy rain even when the gutter is clean.

Gutter repairs in the Northern Beaches has its own rules: heritage areas, salt air and tight access all change how the job is done. Everything below links to the council or standard it comes from, so you can check it yourself.
The Rural Fire Service advises against box gutters and complicated roof shapes on bushfire prone land because they trap debris, and warns that second storey gutters make last minute clearing dangerous. Removing litter from roof, valleys and gutters before summer is part of protecting the house.

Gutters here have to swallow concentrated bursts, which is exactly when an undersized or leaf packed system overflows into the eaves.

Wind, shelter and areas the rain never washes push the real corrosivity higher still, which is why the steel grade used here is not the one used inland.

On a coastal home that means eaves, awnings and wall abutments need washing deliberately.

It can. On the Northern Beaches Council bush fire prone land map, Category 1 vegetation carries a 100 metre buffer and categories 2 and 3 carry 30 metres, so even a cleared block can be mapped and work on it can pull in AS 3959 requirements. The Rural Fire Service also advises clearing litter from roofs, valleys and gutters before summer.
Terrey Hills, on the Northern Beaches, averages 1,216mm of rain a year, close to central Sydney, but with a sharper autumn peak of 175mm in March alone. The June 2016 east coast low dropped 226.6mm on Sydney in three days with gusts to 98km/h, and flashings, fixings and gutter capacity here are judged against that storm.
Northern Beaches roofs corrode faster because much of the peninsula is a surf marine environment. BlueScope names Manly Beach as its metropolitan example of that class, the harshest of its three salt classes under AS 4312, and wind, shelter and areas the rain never washes push real corrosivity higher still.
