Thatched roofs are durable and beautiful, but like any roof, they need regular maintenance to stay in good condition. Spotting problems early can save you money and help extend the life of your thatch. Here are five key signs that your roof may need repair.

1. Loose or Missing Thatch

If you notice areas where the reed looks thin, patchy, or has slipped out of place, it’s a clear sign that repairs are needed. Left untreated, gaps can let in water and cause more serious damage.

2. Moss or Algae Growth

A small amount of moss is normal, but heavy growth holds in moisture and speeds up decay. If moss or algae is spreading, it may be time for moss removal and an inspection.

3. Damaged or Worn Ridge

The ridge of your roof usually wears out before the main coat. If it looks cracked, uneven, or has lost definition, it may need replacing to keep the rest of the thatch secure.

4. Sagging or Uneven Areas

A healthy thatched roof should look neat and even. If you see sagging, dips, or uneven patches, it could mean the underlying structure or thatch layers are failing.

5. Leaks or Damp Inside the Property

The most obvious warning sign is water coming through. If you notice damp patches, leaks, or a musty smell indoors, urgent repairs are needed to prevent further damage.
