Traditionally thatch roofs have been fitted with one of three materials: Long straw, Combed wheat reed or Water reed. In recent years, there has been a shortage in some thatching materials and some reed has been imported.

Always consult a Master Thatcher if you propose having any work done. If you are considering reroofing your property and using a different material then you may need to consult your local conservation officer and if the property is listed the local authority.

The various types of thatch have different life spans, some roofs may last longer than others, and a ridge will require repair sooner.

There are a number of factors that will influence the longevity of a thatched roof. Of critical importance is the pitch and design, its location, and timely maintenance.

As a rough guide only, the following life expectancies might reasonably be anticipated:

• Ridges - 8 - 12 years, dependent upon style and material used.
• Longstraw - 5 - 20 years.
• Combed Wheat - 20 - 30 years
• Water Reed - 30 years plus.

Nesting birds, mice, rats and even squirrels can end up making a hole in your pocket as well as your thatch, if they decide to set up home in your roof. However, you can live peacefully with wildlife if you follow these simple guidelines:

Walk around your property and have a good look at the roof weekly. Pieces of your thatch sticking out in loose clumps, with holes above, may mean wildlife.

• If so, contact a professional thatcher or pest control officer for immediate advice. Beware of damage to electric wires and to the flashings around chimneys.
• Deal with repeat offenders - wire netting all over the roof will prevent birds and vermin from gaining entry. He recommended that this is combed wheat roofs, long straw, and for water reed roofs if birds and rodents are a persistent problem.
