1. Change Chip or Broken Tiles All Over the Roof

The first step in roof restoration is to identify and replace chipped or broken tiles across the entire roof. Damaged tiles can cause leaks, compromise the roof’s structure, and lead to further damage. A thorough inspection is carried out to locate all defective tiles. Once identified, the old tiles are carefully removed and replaced with new, matching tiles. This ensures the roof’s integrity and maintains its appearance. Proper alignment and secure fitting of each tile are crucial to prevent movement and future issues. This step is foundational in preparing the roof for further restoration processes.

2. Re-Cut Valley Tiles or Clip if Required and Install Storm Seal on Valleys

Valley tiles, located where two roof slopes meet, play a critical role in channelling water off the roof. During restoration, valley tiles are re-cut or clipped if necessary to ensure a perfect fit and alignment. This prevents water from penetrating beneath the tiles. Additionally, a storm seal is installed in the valleys to provide extra protection against water ingress during heavy rains. The storm seal acts as a barrier, preventing leaks and ensuring that water flows efficiently into the gutters. Properly securing and sealing valley tiles is vital for the roof’s long-term durability and water resistance.

3. Re-Bed Ridge Caps

Ridge caps, which cover the highest points of the roof, are re-bedded during restoration to maintain stability and prevent water penetration. Over time, the bedding material (usually sand and cement) can deteriorate, causing ridge caps to loosen or crack. In this step, the old bedding is carefully removed, and a fresh layer of mortar is applied. The ridge caps are then repositioned and firmly bedded into place. Proper alignment and secure bedding ensure that the ridge caps are stable, aesthetically pleasing, and capable of withstanding harsh weather conditions without shifting or cracking.

4. Repoint Ridge Caps

Repointing involves applying a flexible, weather-resistant material over the bedding of ridge caps to seal any gaps and protect against water ingress. After re-bedding, a flexible pointing compound is applied along the edges of the ridge caps, creating a strong bond and smooth finish. This compound accommodates natural roof movement, preventing cracks and ensuring long-term protection. Repointing not only enhances the appearance of the roof but also provides a durable seal that resists water penetration, wind uplift, and other weather elements. This step is crucial for maintaining the roof’s structural integrity and prolonging its lifespan.

5. Change Flue Flashings

Flue flashings, located around roof penetrations like chimneys or exhaust flues, are critical in preventing leaks. During restoration, old or deteriorated flue flashings are replaced with new, durable ones. The process involves carefully removing the old flashing and installing a new one that fits snugly around the flue, ensuring a watertight seal. The new flashing is then sealed and secured to withstand harsh weather conditions. Properly installed flue flashings prevent water from seeping into the roof cavity, reducing the risk of leaks, mold growth, and structural damage to the roof and interior of the building.

6. Change Gables Flashings with Wakaflex or Fast Flash Lead-Free Flashings

Gable flashings, which protect the edges of the roof where it meets a wall or another surface, are replaced during roof restoration. Wakaflex or Fast Flash lead-free flashings are commonly used due to their flexibility, durability, and environmental friendliness. The old flashings are carefully removed, and the new flashings are installed to fit perfectly along the gable edges. These flashings are designed to create a watertight seal while allowing for slight roof movements. The new installation ensures long-term protection against water ingress, preventing leaks and maintaining the roof’s aesthetic appeal and structural integrity.

7. Blow Roof and Gutters and Clean Downpipes

Blowing off debris from the roof and cleaning gutters and downpipes are essential steps in roof restoration. Over time, leaves, dirt, and other debris can accumulate, leading to blockages that impede water flow. Using high-powered blowers, the roof is cleared of all loose debris, followed by thorough cleaning of gutters to ensure they are free of obstructions. Downpipes are flushed out to remove any blockages, ensuring efficient drainage. This process prevents water from backing up and causing damage to the roof, walls, and foundation. A clean roof and drainage system are vital for overall property maintenance.

8. Clean Roof with High-Pressure Wash

High-pressure washing is used to clean the roof thoroughly, removing dirt, moss, algae, and any remaining debris. The process involves using a high-powered washer that applies water at around 4000 PSI, ensuring deep cleaning without damaging the roof tiles. This step not only enhances the roof’s appearance but also prepares it for the application of sealers and coatings. Special care is taken to avoid lifting or damaging tiles during the wash. Once cleaned, the roof is left free of contaminants, providing a clean surface that allows sealers and paints to adhere more effectively.

9. Use Clear Sealer on Roof Tiles After Roof Washing Using Roofbond Shieldseal W

After the roof has been cleaned, a clear sealer such as Roofbond Shieldseal W is applied to protect the tiles. This sealer penetrates deep into the tile surface, forming a protective barrier that enhances water resistance and prevents moss and algae regrowth. The clear sealer also binds the tile surface, reducing porosity and making future maintenance easier. Applying the sealer ensures that the tiles remain in good condition for longer, preventing wear from environmental exposure. This step is crucial in extending the life of the roof and ensuring a clean, well-maintained appearance over time.

10. Use Hi-Build to Fill Pores in Tiles – We Use Roofbond Hi-Build Ultimate Primer

Roof tiles, especially older ones, often develop pores and minor cracks that can lead to water absorption and damage. The application of Roofbond Hi-Build Ultimate Primer fills these pores and imperfections, creating a smooth, sealed surface. This high-build primer is designed to penetrate deep into the tile, reinforcing its structure and providing a solid base for subsequent coatings. By sealing the pores, the primer enhances the roof’s durability, reduces water absorption, and prevents long-term damage. This step is essential in ensuring that the roof is adequately prepared for the final topcoat applications.

11. Two Coats of Paint with Roofbond Membrane Paint (12 Years Warranty)

The final step in roof restoration involves applying two coats of Roofbond Membrane Paint. This paint is specifically designed for roof tiles, offering excellent durability, UV resistance, and color retention. The first coat serves as a base, providing adhesion and coverage, while the second coat adds depth and protection. Roofbond Membrane Paint comes with a 12-year warranty, ensuring long-term performance and protection against harsh weather conditions. The paint not only enhances the roof’s appearance but also adds an extra layer of protection against the elements, ensuring the roof remains in optimal condition for years to come.
