Who Fixes Roof Leaks?

One of the most common questions homeowners ask is: “Who fixes roof leaks?” In Victoria, the answer is a licensed Roof Plumber.

At King and Sons Plumbing, our team is fully licensed to handle the complex hydraulics of your roof, ensuring that every repair meets Australian Standards and protects your home’s structural integrity.

How to Find a Leak in Your Roof (The “Inside-Out” Method)

Before you can learn how to fix leaking roof issues, you have to find the source. Water is a master of disguise; it can enter through a ridge cap, run three meters down a rafter, and drip through your ceiling in a completely different room.

How to Fix a Leaking Roof from the Inside

If it’s currently raining, your first priority is damage control.

1. Clear the Area: Move furniture and electronics away from the drip.

2. The Bucket and String Trick: Place a bucket under the leak. If the water is running along a beam, tie a piece of string to the beam and lead it into the bucket. This directs the flow and prevents splashing.

3. Trace the Path: Head into the roof cavity (if safe) with a torch. Look for “shining” wood or damp insulation. Follow the moisture trail to its highest point—that is your entry hole.

How to Repair Roof Leak Issues: A Material Guide

The method for how fix roof leak problems depends entirely on whether you have tiles or metal sheeting.

How to Fix Leaking Roof Tiles

Melbourne’s older suburbs are filled with beautiful terracotta and concrete tiles, but they are prone to cracking.

• Replacing a Tile: If you have a cracked or broken tile, the only permanent fix is to replace it. Carefully lift the overlapping tiles, slide out the broken piece, and slide in a matching replacement.

• Fixing Slipped Tiles: Sometimes tiles haven’t broken; they’ve just “slipped” due to wind or age. Sliding them back into position and ensuring they “lock” with the surrounding tiles can stop a leak instantly.

• Ridge Capping: If the leak is at the very peak of your roof, the “pointing” (the mortar holding the top tiles) has likely cracked. This requires professional repointing with a flexible acrylic compound.

How to Fix a Leaking Metal Roof

Metal roofs (like Colorbond) are durable, but they aren’t invincible.

• How to Patch a Roof Leak: For small rust holes or punctures, you can use a specialized metal patch kit or high-grade bitumen flashing tape.

• Screw Holes: Often, the rubber washers on roof screws perish in the Melbourne sun. Replacing the old screws with new ones featuring “DEKS” washers is a simple and effective fix.

How to Fix Leaking Roof Gutters

A “roof leak” is often actually a gutter failure. When gutters are blocked or sagging, water backs up under the eaves and into your wall cavities.

How to fix leaking roof gutters:

1. Clear the Debris: Most leaks are caused by simple blockages. Clear your gutters and downpipes to allow water to flow.

2. Seal the Joints: Gutter leaks usually happen at the seams. Clean the area with a wire brush and apply a generous bead of silicone-based gutter sealant.

3. Correct the Fall: If water is “pooling” in one spot, your gutter brackets have likely sagged. Re-aligning the brackets ensures the water flows toward the downpipe rather than over the back of the gutter.

Why DIY Isn’t Always the Answer

While knowing how to patch a roof leak is great for emergencies, there are three reasons to call a professional plumber.

1. Safety: Working on a wet or steep roof is incredibly dangerous. Falls from heights are a leading cause of injury in the DIY community.

2. The “Hidden” Leak: Some leaks are caused by “capillary action,” where water is sucked upward between overlapping sheets. These require expert diagnosis.

3. Insurance Compliance: Many insurance companies will reject a future claim if they find “unlicensed plumbing work” was performed on the roof.
