How long does a thatched roof last?
Whether you own, or are planning to own, a thatched property, it's crucial to know how often you'll need to pay for rethatching.
The average lifespan of a thatched roof is in the region of 30 years - certainly for water reed thatch or combed wheat. Straw might only last 20 years. However, it's not unheard of for well-installed, quality thatch to last up to 60 years.
When planning for your rethatching, several considerations can help to prolong your investment:
Material used: As mentioned, long straw won't last as long as Norfolk reed, so weigh up the initial cost with the longevity of the material
Quality of installation: A well-installed thatched roof will have a longer lifespan
Regular maintenance: Annual inspections and timely repairs can help to nip smaller issues in the bud before they become more costly to fix
Roof angle: Steeper roofs shed water more effectively, reducing wear
Weather and surrounding environment: Thatched roofs tend to last longer in drier areas, while nearby overhanging trees can accelerate deterioration

Replacement vs. new thatched roof cost
The cost of installing a brand new thatch roof will likely be around the same as replacing an existing one.
On average, expect to pay around £20,000 for a replacement thatched roof
A typical rethatch could take anything up to 10 weeks (depending on the size and scope of the job)
Ridge replacement
Ridge replacement is likely to cost in the region of £7,000and could be needed every10-15 years
This job can take anything from 1-2 weeks (depending on the intricacy of the pattern and whether any other repairs are needed)
Factors that affect thatched roof cost
Three main factors affect the cost of a thatched roof:
1. The size of the roof and complexity of the design
A small roof (approx 60m²): Average cost - £12,000
A medium roof (approx 80m²): Average cost - £16,000
A large roof (approx 100m²): Average cost - £19,000
2. The thatching material you choose
Norfolk reed is incredibly durable (50+ years) but as such, has a premium price tag
Combed wheat is a mid-range option with a traditional appearance, expected to last between 25-35 years
Long straw has a lower cost but a shorter lifespan of around 15-25 years
3. Location and availability of skilled thatchers
The cost of labour varies depending on your location. Areas with fewer skilled thatchers may face higher prices due to demand.
Labour day rates for skilled thatchers typically sit around £300
A typical, medium-sized roof (approx. 80m²) might take 8 weeks for two experienced thatchers to complete
Additional costs to consider
In addition to the cost of the thatch material and labour, you may need to budget for several other expenses:
Netting to deter nesting birds and pests
Fire retardant treatments and sprays
Specialist decorative thatch designs
New roof timbers
As you may be aware, thatched properties often have higher building insurance premiums due to fire risks. Speak to a specialist for accurate quotes.
Maintenance and ongoing costs of thatched roofs
As with many aspects of home maintenance, regular checks can often help to spot minor issues as and when they appear. This can minimise the potential for them to turn into larger, more costly repairs in the future.
General maintenance might cost between £10- £20 per m²
An annual inspection on a thatched roof typically costs around £100, although some thatchers offer this service free of charge
It's not uncommon to spend £120- £200 per m² on thatched roof repairs annually
