Roof Leak Detection is about finding exactly where water gets in, so you pay to fix the real cause and not a guess. It helps when a stain keeps returning or the leak only shows in heavy rain. One request gets prices from local roofers who trace leaks.

Get Roofing QuotesWhen to Book a Leak Trace
- The leak came back. A previous repair did not stop it.
- The stain moves. Water travels along sheets, battens or underlay and drips far from the entry point.
- Only in certain weather. Leaks that appear with wind-driven rain often point to ridges, flashing or laps.
- Damp with no obvious cause. Damp walls or mould near the roofline.
How Leaks Are Found
- Roof space check. Looking from inside for light, water trails and wet timber.
- Outside inspection. Tiles, sheets, screws, ridge capping, valleys, flashing and penetrations.
- Water testing. Wetting sections of the roof one at a time while someone watches inside.
- Moisture readings. Some roofers use moisture meters on ceilings and flat roof surfaces.
Common Leak Sources
- Flashing. Lifted or perished flashing at walls, chimneys and skylights.
- Valleys. Blocked or rusted valley gutters. See roof valley repairs.
- Fixings. Perished washers and rusted screws on metal roofs.
- Flat roof membranes. Cracks, blisters and lifted seams in torch-on or coatings.
After the Leak Is Found
Small faults are often fixed on the same visit. Bigger repairs are quoted separately, so ask for photos of the source and a written scope before you agree.

Get Roofing QuotesWhat Affects the Price
- How hard the leak is to trace. Intermittent leaks may need water testing over a few hours.
- Roof access. Steep, high or fragile roofs take more time and safety equipment.
- Report required. A written report with photos costs more than a verbal finding.
- Fix on the day. Some quotes include a minor fix, others are detection only.
How Getting Quotes Works
- Request. Tell us the work, your area and how to reach you. Photos help.
- Match. Your request goes to local roofing contractors suited to the job, with your permission.
- Quote. Contractors contact you, inspect if needed and give a written price.
- Compare. Check scope, materials, warranty and payment terms side by side, then hire one or nobody.
Roof Leak Detection FAQs
Why is the leak not above the stain?
Water often runs along sheets, battens or underlay before it drips, so the entry point can be a metre or more away.
Can a leak be traced on a dry day?
Yes. A roofer can run water over sections of the roof to recreate the leak while someone watches inside.
Is leak detection worth paying for?
It usually is when a leak has returned after repairs, because it stops you paying for fixes in the wrong place.
Will I get a report?
Ask for one if you need it for insurance or a landlord. A detailed report with photos costs about R1,000 - R1,800.
