Tile roof repair is needed when you notice signs of damage such as cracked or missing tiles, leaks inside the home, Blockage of Gutters or Downpipes  or water flowing backward , or sagging in the roof structure or Flashings got cracks or ripped off. Additionally, if tiles are worn, weathered, or covered in moss and algae, it may indicate they are compromised and require attention. Regular inspections through reputed company or qualified tradesman(Must), especially after storms or heavy winds, can help identify issues early. Repair is also necessary if the roof is aging, typically after 10-15  years, depending on the material and exposure to harsh conditions. Timely repairs prevent more extensive damage and extend the roof’s lifespan.

Repairing a tile roof involves several steps to ensure a thorough and lasting fix. Below is a detailed guide to the process:

1. Inspect the Roof

• Start by conducting a comprehensive inspection to identify the chipped, cracked, or broken tiles. Check for other signs of damage like deteriorated mortar, blocked gutters, and worn-out flashings. Mark the areas that need repair.

2. Safety Precautions

• Before starting any repairs, wear appropriate safety gear, including a harness if the roof is steep or install Roof Safety Guard rails. Ensure you have a stable ladder and consider using roof jacks to create a safe working platform.

3. Remove the Damaged Tiles

• Carefully lift the tile above the damaged one using a pry bar. Slide out the broken tile, taking care not to damage the surrounding tiles. If the tile is adhered with mortar, gently chip away the mortar before removing the tile. Set aside the broken tiles and clear any debris from the area.

4. Replace the Tile

• Insert the new tile in place of the damaged one, ensuring it aligns correctly with the adjacent tiles. If the tile was originally set in mortar, apply fresh mortar to secure it. For tiles that clip into place, make sure the clips are properly attached.

5. Remove Old Mortar and Rebed Tiles

• If the mortar bed has deteriorated, you’ll need to remove the old mortar completely. Use a hammer and chisel to carefully chip away the mortar without damaging the tiles. Clean the area thoroughly before applying a new mortar bed. Place the tiles back into the new mortar, pressing them firmly to ensure a secure bond.

6. Apply Flexible Pointing

• Once the tiles are rebedded, apply flexible pointing along the edges of the tiles. This pointing material is crucial as it provides a waterproof seal and accommodates any slight movements in the roof structure due to weather changes. Smooth the pointing with a trowel for a neat finish, ensuring it covers all joints and gaps.

7. Clean Gutters

• Clear any debris from the gutters to prevent water backup, which can lead to leaks. Check for any signs of wear or rust in the gutters and downpipes, and replace sections if necessary. Proper gutter maintenance helps in diverting water away from the roof, reducing the risk of future damage.

8. Replace Valleys if Required

• Roof valleys, where two roof sections meet, are prone to damage and leaks. Inspect the valleys for rust, cracks, or dislodged tiles. If you find any issues, remove the damaged valley materials and replace them with new metal or tiled valley components. Ensure they are correctly aligned and sealed to prevent water infiltration.

9. Replace Flashings

• Flashings, especially around chimneys, vents, and skylights, are essential for preventing water entry. If the flashings are corroded or cracked, remove them carefully and replace them with new ones. Use appropriate sealants to ensure a watertight seal around the flashings.

10. Change Flu Flashings

• Flu flashings around exhaust vents and flues often wear out over time due to exposure to heat and weather. Remove the old flashing and install a new one, ensuring it is properly sealed to prevent leaks. Check that the flashing is securely attached and overlaps the roofing material correctly.

11. Final Inspection

• After completing all repairs, conduct a final inspection to ensure everything is in place and properly sealed. Check the alignment of the tiles, the integrity of the mortar, and the effectiveness of the flashings and valleys. Make sure there are no loose tiles or gaps.

12. Regular Maintenance

• To extend the life of your roof, schedule regular inspections and maintenance. Address minor issues promptly to avoid more extensive and costly repairs in the future.

This step-by-step approach ensures that the roof is not only repaired but also reinforced against future damage, keeping it in good condition for years to come.
