My gutters overflow in heavy rain — is that a roof problem?

It can be. Overflowing gutters usually mean a blockage, undersized gutters, or a fall that's gone out of level. If water is backing up under the roof edge, it can enter the ceiling space. We clear, re-level and re-seal gutters and check the roof edge for damage.

What's a flashing and why does it fail?

Flashings are the metal strips that seal joints — where the roof meets a wall, around chimneys, skylights and penetrations. They fail when the sealant perishes (UV and salt speed this up), when they lift in wind, or when they're poorly installed. We re-seal or replace flashings with coastal-grade materials.

Do you install leaf guards on gutters?

Yes, where appropriate. Leaf guards suit homes with overhanging trees, but they need the right type and regular checks or they can make blockages worse. We'll advise honestly whether a leaf guard is right for your roof and trees.

Can a box gutter be repaired or does it need replacing?

Box gutters can often be re-lined with a compatible membrane rather than fully replaced, provided the substrate is sound. We assess the condition and recommend repair, re-line or replacement — re-lining is usually the most cost-effective fix.

How do I stop water getting in where the roof meets the wall?

That's a step flashing or apron flashing issue. We re-seal or replace the flashing with a continuous coastal-grade apron and check the wall cladding above. A proper flashing beats a bead of sealant every time.

Gutter, Valley & Flashing Repairs Lennox Head & Northern Rivers

Gutters, valleys and flashings are where most preventable roof leaks start. On Northern Rivers homes, leaf build-up, salt-caked debris and UV-perished sealants block water paths and force water where it shouldn't go. We clear, re-level, re-seal and replace gutters, valleys and flashings with coastal-grade materials so water stays in its channel and out of your ceiling.

Why this matters on the Northern Rivers coast

Gutters, valleys and flashings do most of the water-handling work on a roof, so they're where most preventable leaks begin. On Northern Rivers homes, leaf fall from coastal scrub, salt-caked debris and UV-perished sealants combine to block water paths and force water over edges and into the ceiling. A valley that's half-full of leaf mulch doesn't need a storm to leak — a normal downpour will do it.

The good news is these are the most affordable roof problems to prevent. Clearing and re-sealing a valley or gutter costs a fraction of a re-roof, and a properly re-levelled gutter with a sound flashing will keep water in its channel for years. We always show you photos of the blockage or rust so you can see exactly why the water was going where it shouldn't, and we'll tell you honestly whether a component needs replacing or just clearing.

Signs you need this

Gutters overflowing or pulling away from the fascia
Water staining on fascia boards or under eaves
Rust or holes in gutters or valley trays
Leaf and debris build-up blocking water flow
Water entering where the roof meets a wall or chimney
Sealant cracked, shrunk or missing around flashings

What we do, step by step

1
We inspect gutters, valleys and all flashings, photographing blockages, rust and failed seals.
2
Gutters and valleys are cleared of leaf and salt-caked debris and flushed through.
3
Rusted or holed sections are patched or replaced; box gutters are re-lined where suitable.
4
Flashings are re-sealed or replaced with coastal-grade apron, step and penetration flashings.
5
Gutter fall is checked and re-levelled so water runs to downpipes, not over the edge.
6
You receive a before/after photo report and a written workmanship warranty.

What's included

Full inspection of gutters, valleys and all flashings, photographed
Clearing of leaf and salt-caked debris, gutters and valleys flushed through
Patch or replace rusted/holed sections; box-gutter re-lining where suitable

Materials we use — and why they suit coastal homes

We use colour-matched Colorbond flashing metal, UV-stable roofing sealants, and compatible valley and box-gutter membranes suited to coastal UV and salt. Where leaf guards are appropriate we fit the right type for your roof profile and tree cover.

How much does it cost?

from $300 for clearing and sealing — replacements quoted after inspection

Clearing and re-sealing a gutter or valley is the most affordable fix. A rusted valley replacement starts from $500 — old valley irons removed and replaced with new Colorbond valleys. Full flashing replacement or box-gutter re-lining costs more and depends on length and access. We give you a fixed quote before any work starts.

Repair, restore or replace?

A blocked or unsealed gutter or valley is repaired (cleared and re-sealed). A rusted-through gutter or valley tray is replaced. Flashings are re-sealed where the metal is sound, and replaced where the metal is perished or poorly installed. We'll show you photos and recommend the right option for each component.
