One of the most common questions we hear is: “How long will my thatched roof last?” The answer depends on several factors, but with the right care, a thatched roof can be an investment that protects your home for decades.

Average Lifespan of a Thatched Roof

Water Reed: 25–40 years
Wheat Reed (Devon Reed): 15–25 years
Ridges: 10–15 years (these wear faster and usually need replacing before the main coat)

These timescales can vary depending on location, weather exposure, the quality of materials used, and how well the roof is maintained.

Factors That Can Affect Lifespan

Material choice – Water reed is generally harder and more durable, while wheat reed offers a softer, traditional finish.
Maintenance – Regular inspections, moss removal, and patch repairs help extend the life of your roof.
Exposure – Roofs facing prevailing winds and heavy rain may wear quicker than those in more sheltered spots.
Craftsmanship – A well-laid roof by skilled thatchers will always last longer than one poorly installed.

How to Make Your Thatch Last Longer

Arrange inspections every 2–3 years
Replace the ridge before it deteriorates too far
Clear moss and debris to prevent water retention
Use netting if wildlife is damaging the thatch
