How Our Tile Roof Waterproofing System Works

Our Concrete Tile Roof Waterproofing System is designed to address the most common problem areas on tiled roofs, including ridges, valleys, flashings, and parapet walls. Here’s a step-by-step breakdown of how we waterproof your roof:

Step 1: Inspection & Preparation

The first step in our process is a thorough inspection of your roof. We look for signs of damage, such as cracked cement, loose ridge tiles, or broken tiles. Any loose cement is removed, cracks are raked open, and damaged tiles are replaced to ensure a solid foundation for the waterproofing process.

Step 2: Filling & Repair

Once the roof is prepared, we fill gaps and holes with FibreCrete, a plaster-like mixture that provides a strong, durable repair. For smaller cracks, we use DampEnd, a fibre-reinforced cementitious coating that seals and strengthens the surface.

Step 3: Priming

Next, we prime the entire area to be waterproofed with Penetrar, a multi-purpose concrete primer. Penetrar penetrates the porous concrete, binds loose particles, and enhances adhesion for the membrane to follow.

Step 4: Membrane Application

To strengthen fixed sections, overlaps, and joints, we apply StretchSeal, a flexible waterproofing membrane. This membrane helps absorb movement and prevents hairline cracks from forming.

Step 5: Membrane Adhesion

We embed the StretchSeal membrane using Repello, an adhesion promoter with excellent binding properties. Repello ensures the membrane is securely attached to the substrate, providing a seamless and durable finish.

Step 6: Waterproofing

Finally, we apply three layers of HydroSeal HF, a high-performance acrylic coating designed for long-term protection. HydroSeal HF is specifically formulated for all types of roof surfaces, including concrete roof slabs, parapet walls, tiled roofs, valleys, ridges, vents, and flashings. Once the waterproofing is complete, we colour-coat the surface to match your roof tiles for a seamless, aesthetically pleasing finish.

Tile Roof Waterproofing Problems

Common Causes of Roof Leaks on Tiled Roofs

Understanding the causes of roof leaks can help you take proactive steps to protect your property. Here are the most common issues we encounter:

  1. Cracked Cement

Over time, the cement used to secure ridge tiles and flashings can crack and deteriorate, allowing water to seep through.

  1. Displaced Ridge Tiles

Ridge tiles can become loose or displaced due to weather conditions or poor installation, creating gaps where water can enter.

  1. Damaged Flashings

Flashings, which are used to seal joints and transitions on the roof, can wear out or become damaged, leading to leaks.

  1. Broken or Missing Tiles

Broken or missing tiles create openings for water to penetrate the roof structure.

  1. Poor Installation

Improper installation of tiles or waterproofing materials can compromise the integrity of the roof, leading to leaks and other issues.

How to stop a tiled roof from leaking


Waterproofing Tile Roof Ridges – StretchSeal Waterproofing System

Leaks on tile roof ridges typically occur due to:

  1. Cracked or Missing Filling: The material used to join the ridge line tiles has cracked or fallen out.
  2. Storm Damage: Severe weather conditions can crack, loosen, or blow off the ridge tile capping.

To repair a damaged ridge line, follow these steps:

  1. Preparation: Remove any loose debris and clean the area thoroughly.
  2. Filling Gaps: Fill the open sections with FibreCrete and smooth it out using Penetrar. Penetrar strengthens the FibreCrete, locks down dust, and prepares the surface for waterproofing.
  3. Applying the Membrane: Once dry, apply the StretchSeal Membrane with Flex over the repaired sections, overlaps, and joints.
  4. Final Coating: Apply a coat of HydroSeal HF to reinforce the system and complete the waterproofing process.
  5. Color Matching: If the roof is not being painted, the ridges can be color-coded to match the existing roof tiles for a seamless finish.

Waterproofing Tile Roof Valleys – StretchSeal Waterproofing System

Valleys on tile roofs are prone to leaks when:

  1. Insufficient Gaps: The space between tiles in the valley is too narrow, leading to clogging from leaves, dirt, or debris.
  2. Installation Errors: The under-tile flashing is incorrectly installed, or the roof slope is too shallow (less than 17.5 degrees).

To address a leaking valley:

  1. Cleaning and Preparation: Clean the valley thoroughly and ensure all tiles are properly seated according to the roof design.
  2. Adjusting Tile Gaps: If the under-tile flashing is correctly installed and the roof slope is adequate, open the valley tiles to create a 50mm gap between them. This allows water to flow freely without spilling over the flashing.
  3. Alternative Solution: If adjusting the gaps is not possible, fill the entire valley with FibreCrete and smooth it out using Penetrar. This strengthens the surface and prepares it for waterproofing.
  4. Applying the Membrane: Apply the StretchSeal Membrane with Flex, ensuring no cavities are left between the cement and the membrane.
  5. Final Coating: Finish with a coat of HydroSeal HF to reinforce the system. If the roof is not being painted, the valley can be color-matched to the existing roof tiles.

Waterproofing Flashing Sections on Side or Parapet Walls

Leaks often occur at side or parapet walls due to:

  1. Incorrect Flashing Installation: The under-tile cut-in flashing is improperly installed.
  2. Poor Sealing: The cut-in section on the wall or overlaps and joints are not sealed correctly.

To fix leaking side wall flashing:

  1. Preparation: Remove old and loose debris, and clean the area thoroughly.
  2. Creating a Slope: Install a 45-degree slope using FibreCrete to direct water away from corners and fill any cavities that could allow water penetration.
  3. Strengthening the Surface: Smooth and strengthen the FibreCrete with Penetrar.
  4. Applying the Membrane: Apply the StretchSeal Membrane with Flex over the repaired sections, ensuring no cavities are left between the cement and the membrane.
  5. Final Coating: Apply a coat of HydroSeal HF to complete the waterproofing process.

Waterproofing Cracked Roof Tiles

Cracked roof tiles are a common cause of leaks, second only to loose or displaced tiles. While replacing broken tiles is ideal, cracked tiles can be effectively repaired using the StretchSeal Waterproofing System:

  1. Preparation: Clean the tile and remove any loose debris.
  2. Applying Flex: Apply a coat of Flex waterproofing directly over the crack.
  3. Strengthening with Membrane: Reinforce the section with StretchSeal Membrane, overcoating it with Flex.
  4. Final Coating: Once dry, apply a coat of HydroSeal HF to secure and waterproof the repaired tile.
