Roof Leak Detection & Repair Lennox Head & Northern Rivers
Roof leak repair starts with finding the true source — not just where the water shows up inside. On Northern Rivers homes, most leaks trace to a handful of causes: failed screw washers, cracked or displaced tiles, perished flashings, blocked valleys, or unsealed penetrations. We inspect inside and out, trace the leak to its source, and repair the actual failure point so it doesn't come back.
Why this matters on the Northern Rivers coast
Roof leaks in the Northern Rivers rarely happen for one simple reason. Salt air, UV and seasonal storms age fixings and sealants faster than they do inland, so a roof that was fine five years ago can start letting water in without any single dramatic event. The other trap is that water travels — the damp patch on your ceiling is often metres away from the actual entry point on the roof, which is why a quick look from the ground rarely finds the cause.
We take a methodical approach: inspect inside the ceiling space and out on the roof, water-test the likely failure points, and trace the water path back to its source. On coastal homes the usual suspects are failed screw washers, perished flashing sealants, blocked valleys, cracked ridge pointing and unsealed penetrations. Fixing the true source — not just the stain — is what stops a leak coming back after the next downpour.
Signs you need this
- Water stains or brown patches on ceilings or walls
- Dripping sounds or visible drips during rain
- Damp or mouldy smell in the ceiling space
- Paint bubbling or peeling near the top of walls
- Sagging or water-stained insulation in the roof space
- Leaks that only appear during wind-driven rain
What we do, step by step
- 1
We inspect the roof externally and the ceiling space internally, photographing every suspect area.
- 2
We water-test likely failure points (screws, flashings, valleys, ridge caps, penetrations) to reproduce the leak.
- 3
We trace the water path from the interior stain back to the true entry point on the roof.
- 4
We repair the failure point — re-screw, replace tiles, re-bed/repoint ridges, re-seal flashings or clear valleys as needed.
- 5
We check the surrounding area for the same failure mode and fix proactively.
- 6
You receive a before/after photo report and a written workmanship warranty.

Recent job · Ballina
A leak nobody else could fix
This Ballina roof had a leak that several others had already tried to fix, without success. Patching the same spots again wasn't going to work, so it needed a different approach.
We stripped out the old flashings and replaced them with seamed flashings, plus custom-made parapet flashings to suit the roof. Once the work was finished we water tested it, and it no longer leaks. The client was stoked.
What's included
- Internal ceiling-space inspection and external roof inspection, both photographed
- Water-testing of suspect areas to reproduce the leak
- Tracing the water path from the interior stain to the roof entry point
- Targeted repair of the failure point (re-screw, tile, flashing, valley or ridge)
- Proactive check of surrounding areas for the same failure mode
- Before/after photo report and written workmanship warranty
Materials we use — and why they suit coastal homes
We use Class 4 coastal-rated screws, matching replacement tiles, UV-stable roofing sealants and colour-matched flashings suited to Northern Rivers sun and salt. Where a leak runs through a valley or box gutter, we clear it and re-line with a compatible membrane rather than just slapping sealant over the top.
How much does it cost?
from $350 for a traced and repaired leak — quoted after inspection
Most single leak repairs land between $350 and $900 depending on the cause, height, access and materials. Tracing a hard-to-find leak may need a short water-test. We give you a fixed quote before any work starts — no open-ended hourly billing.
Repair, restore or replace?
If the leak is localised and the rest of the roof is sound, a targeted repair is the right call. If leaks are appearing in multiple places, the roof is past its service life, or screws are failing across the whole roof, a re-screw or section replacement is better value than chasing leaks one at a time. We'll show you photos and an honest recommendation.
