Saltbox Roof

1. Tile or Slate Damage

• Cracked, slipped, or missing tiles
• The longer slope is more exposed to weather
• Can lead to leaks if not repaired

2. Uneven Weathering

• One side (usually the longer slope) ages faster
• More exposure to rain, wind, and sunlight

3. Ridge Issues

• Ridge tiles can loosen or crack
• Mortar may deteriorate over time

4. Gable End Problems

• The vertical wall at the short side can crack
• Wind pressure can weaken this area

5. Roof Leaks

• Common at ridge, flashing, and eaves

6. Drainage Imbalance

• Water runs more heavily down the long slope
• Can overload gutters or cause pooling at the base

7. Timber Stress

• Uneven load distribution can cause shifting

8. Flashing Failure

• Around chimneys, valleys, or roof joints

minor Repairs

• Replace broken or missing tiles/slates
• Repoint ridge tiles
• Fix flashing and seal leaks
• Clear gutters and improve drainage

moderate Repairs

• Replace sections of underfelt or battens
