A thatched roof does not typically need to be completely replaced all at once; instead, it requires ongoing maintenance and periodic partial repairs throughout its lifecycle. The ridge of a thatched roof, which is the most vulnerable point exposed to wind and rain, usually needs to be completely re-ridged or replaced every 10 to 15 years using fresh reed or straw. Meanwhile, the main body of the roof, known as the coat work, can last for decades before needing substantial patching or a full re-thatch. Regular annual inspections by a master Thatcher help identify worn patches, loose fixings, or moss accumulation early, allowing for minor repairs that significantly extend the overall lifespan of the roof.
