Ridge Tile Re-Fixing – Upton Road, Bexleyheath

Need to put back 2 curved tiles (the ones from the edge, probably called ridge tiles?) that came out after last week’s strong winds. The tiles are still on the roof and can still be used. They came out due to the very sandy cement used (not good one). I can share some pictures about it.

Understanding Ridge Tile Issues

Ridge tiles, which cap the apex of a pitched roof, provide essential protection against water ingress and wind uplift. If installed with poor-quality mortar, they can become dislodged during high winds, as experienced recently in Bexleyheath. Re-fixing them correctly ensures the roof remains secure and weatherproof.

Steps to Re-Fix the Ridge Tiles

The process of re-fixing ridge tiles involves the following steps:

1. Inspection and Preparation:
   • Assess the existing ridge area for additional weak points.
   • Check for underlying damage to the roof structure or adjacent tiles.
   • Clean off loose or sandy cement to provide a solid base for the new mortar.
2. Re-Bedding the Ridge Tiles:
   • Apply a high-quality mortar mix (3:1 sand to cement ratio) for durability.
   • Position the existing ridge tiles securely and ensure a snug fit.
   • Use tile clips where possible to provide additional reinforcement.
3. Pointing and Sealing:
   • Neatly point the mortar along the tile edges to ensure a watertight seal.
   • Check for correct alignment and drainage slope.
   • Apply a weatherproof sealant if required.
4. Final Inspection and Cleanup:
   • Ensure the ridge tiles are secure and aligned properly.
   • Remove any debris from the roof and gutters.
   • Provide maintenance advice to the homeowner.

Estimated Costs

The estimated cost for re-fixing ridge tiles in Bexleyheath ranges from £150 to £400, depending on:

• The number of tiles requiring re-bedding.
• Access requirements (scaffolding or ladder).
• The type of mortar and additional reinforcements used.

Common Causes of Ridge Tile Dislodgment

Several factors contribute to ridge tile displacement, including:

• Poor-Quality Mortar: Weak or overly sandy mixes can fail under wind pressure.
• Weather Exposure: Heavy rain and wind can erode the mortar joints over time.
• Incorrect Installation: Improper fixing methods can lead to premature failure.
• Thermal Expansion: Changes in temperature cause tiles and mortar to expand and contract, weakening the bond.

Preventative Maintenance Tips

To prevent future tile dislodgment, consider the following:

• Regular Roof Inspections: Check for cracks or loose mortar annually.
• Use Quality Materials: Ensure a strong mortar mix with correct ratios for durability.
• Weatherproof Sealants: Apply protective coatings to prolong the life of ridge tiles.
• Routine Gutter Cleaning: Prevent water buildup that can weaken the mortar.

Preparing for the Repair

Homeowners can take the following steps to prepare for the repair:

• Ensure clear access to the affected area for ladders or scaffolding.
• Provide photographs to help assess the work required in advance.
• Inform neighbours if shared access may be needed.
