Roof Leak Detection & Repair in the Sutherland Shire

Find the source, not just the stain

A brown stain on your ceiling. It disappears when it's dry, comes back with the next southerly, but every roofer who's looked can't find where the water's getting in. That's one of the most common calls we get — and it's solvable, but only if you trace the leak to its actual source rather than guessing at the symptom.

Water almost never enters directly above the stain. It travels along sarking and timbers and surfaces wherever it finds a gap — sometimes metres away. Fix the stain and you've fixed nothing. Find the source and you've solved it for good.

Shire Roofing tracks down hidden leaks across the Sutherland Shire and repairs them properly. We start with a free inspection, locate the actual entry point, and show you what's failed before we quote. Call (02) 9538 7456.

Where Shire leaks usually start

Years of working on local roofs tells us where to look first, and it depends on which side of the Shire you're on:

• Corroded flashings and valley irons — on the coastal side around Cronulla, Woolooware and Burraneer, salt air rusts the metal that channels water off the roof. A rusted-through valley is a guaranteed leak.
• Failed ridge pointing and cracked tiles — on the older brick-and-tile streets in Miranda, Caringbah, Gymea and Sutherland, perished mortar and porous tiles let water in at the ridges and hips.
• Backed-up gutters — near the bush, leaf-packed gutters push water under the roof edge into the fascia and eaves. We see this constantly in the National Park–fringe suburbs.

How we find it

1. Free inspection — we get on the roof and into the roof space where access allows, and trace the water path back from the stain to the real entry point.
2. Identify everything — we check for the next thing about to fail nearby, so you're not back chasing another leak in a month.
3. Show and quote — you see exactly what's wrong and get a clear price to fix it.
4. Repair — done with materials suited to your roof and its exposure.

The usual culprits, and why they hide

Most "mystery" leaks come down to a handful of failure points that don't show themselves until water is moving. Knowing them is half the job:

• Corroded valley irons — the metal channel between two roof planes carries the most water on the roof. Near the coast salt rusts it from underneath, so it can look fine from above while leaking below.
• Failed ridge and hip pointing — once the mortar perishes, water wicks in at the joints and tracks down inside the roof, surfacing well away from the ridge.
• Lifted or perished flashings — around chimneys, skylights, walls and penetrations, a flashing that's lost its seal lets water in at the one spot rain is driven hardest.
• Cracked or porous tiles — a hairline crack passes water only under wind-driven rain, which is why the leak seems to come and go.
• Backed-up gutters — leaf-packed gutters push water under the roof edge into the fascia; common near the bush and easily mistaken for a roof leak. Guarding the gutters often solves it — see our gutter guard page.

Before the summer storms

The worst time to discover a latent leak is in the middle of an east-coast low, when the roof is already under water and a roofer is hard to reach. Heavy summer storms expose every weakness that's been quietly developing — corroded flashings, hairline tile cracks, tired pointing. A detection inspection now is the cheap insurance against a wet ceiling in January. If a storm has already hit, see our storm and emergency repairs.
