Roof Leak Repair
Melbourne.
Ignoring a roof leak turns a $300 repair into a $15,000 structural problem. We locate the exact source using proven diagnostics and fix it right, the first time.
We Find the Source. Not Just the Symptom.
Many roofers slap a tube of silicone over the obvious spot. Three months later, you're calling someone else. We use a systematic inspection process to locate every possible water entry point before we touch a tile.

The 6 Most Common Causes of Roof Leaks in Melbourne
Understanding the cause is the difference between a permanent fix and a temporary silicone patch that fails in the next storm.
Cracked or Slipped Tiles
Storm damage, foot traffic during solar installation, or simple age can crack tiles. Slipped tiles are especially common after Melbourne's strong northerly winds. A cracked tile in Diamond Creek or Eltham can be invisible from the ground but admit litres of water per hour during rain.
Failed Valley Iron
The sheet metal lining at roof valleys corrodes over 20–30 years, especially on older Melbourne homes. Rust perforations in the valley iron cause significant water ingress. We replace valley iron with corrosion-resistant material and reseat affected tiles.
Cracked Ridge Cap Bedding
Melbourne's temperature extremes crack old cement mortar around ridge caps. Once mortar is cracked, ridge caps shift slightly every time the roof heats and cools. This creates a pumping action that draws water under the cap during rain, even when the crack seems small.
Failed Flashing
Metal flashing around skylights, chimneys, and pipe penetrations corrodes and lifts away from its sealant bedding. A failed skylight flashing in Brighton or Malvern can mimic a tile crack; the water entry point is never directly above where you see the ceiling stain.
Blocked Box Gutters & Valleys
Box gutters embedded in the roof structure are designed to drain from above. When debris blocks them, water backs up behind the tile edge and enters the roof cavity. Tree debris in suburbs like Eltham and Templestowe is a major cause of this issue.
Roof Penetrations
Plumbing vents, antenna brackets, solar mounting hardware, and air conditioning penetrations all compromise the roof membrane. The sealant around these penetrations has a 10–15-year life, after which they become water entry points.
Emergency vs. Scheduled Leak Repair
Different leak scenarios call for different responses. We offer both.
Emergency Call-Out
For active leaks, storm damage, or water entering your ceiling. We aim to be on-site the same day or next morning. Our priority is to stop the water entry immediately with a temporary or permanent fix, then assess the full scope of damage once the weather improves.
- Same-day response available 7 days
- Temporary tarping if permanent repair can't begin in bad weather
- Insurance documentation available on request
Scheduled Repair
For intermittent leaks, leaks that only appear during heavy rain, or leaks discovered during a roof inspection. A proper diagnostic assessment identifies every entry point before we begin repairs, preventing the “we fixed one and found another” situation.
- Full written scope before any work begins
- Photographic evidence of all defects found
- Prioritised repair options with pricing for each
What Does Roof Leak Repair Cost?
Costs vary significantly depending on the cause and extent. Here are typical ranges for common repairs.
Find the True Source With a $199 Diagnostic Inspection
A silicone patch over the wrong spot wastes your money. Our paid inspection traces water to its true entry point and gives you a photo-documented condition report, so your repair is done once, properly.
- Photo-documented condition report of every entry point we find
- Pinpoints the true source, not just the visible symptom
- Fully rebated against any repair over $1,500
