Hip Roof

1. Tile or Slate Damage

• Cracked, slipped, or missing tiles
• Caused by wind, frost, or ageing
• Can quickly lead to leaks

2. Hip Ridge Issues

• The angled ridges have special tiles
• Mortar can crack or erode over time
• Tiles may become loose or fall off

3. Valley Problems

• Where two roof slopes meet, a valley forms
• Debris buildup blocks water flow
• Valley lining can wear or crack

4. Roof Leaks

• Often start at hip edges, flashing, or ridge line

5. Structural Movement

• Settlement or ageing can cause shifting

6. Timber Rot

• Moisture entering the roof can rot rafters and battens

7. Flashing Failure

• Lead flashing can split or lift
• Common around chimneys and joints

minor Repairs

• Replace broken or slipped tiles
• Repoint hip and ridge tiles
• Clear and repair valleys
• Fix flashing

moderate Repairs

• Replace sections of underfelt or battens
• Repair valley linings (lead or fibreglass)
• Fix small structural timber issues

major Repairs

• Replace large sections of tiles
• Repair sagging roof areas
• Replace damaged rafters or trusses
