While thatch is a resilient and long lasting roofing material, the time will come when a full or partial re-thatch is required. Depending on the material of your roof, and the harshness of its environment, re-thatching can be required anywhere from every 20 to 30 years.
Full or partial re-thatch?
A full re-thatch typically involves removing all of the old thatch from the roof, repairing any damage to the roof structure, and applying new thatch to the entire roof. This is a more extensive and costly process compared to a partial re-thatch, but it may be necessary if the existing thatch is in poor condition or if the roof has not been re-thatched in many years.
A partial re-thatch, on the other hand, involves replacing only the damaged or worn-out sections of the roof. This can be a more cost-effective solution if the rest of the thatch is in good condition and does not need to be replaced. During a partial re-thatch, the damaged thatch is removed and replaced with new thatch, and any necessary repairs are made to the roof structure.
In general, a partial re-thatch is less disruptive and time-consuming compared to a full re-thatch, as it only involves working on a portion of the roof. However, the roof may lose some uniformity if the new thatch does not match the existing thatch on the rest of the roof.
When is re-thatching required?
Signs that your roof may need re-thatching include:
- Wear and tear: Over time, the thatch can become worn and damaged due to exposure to the elements and natural deterioration. Signs of wear and tear include thinning, bald patches, and cracks in the thatch.
- Water leaks: If the roof is no longer watertight, it may be time for re-thatching. Water leaks can cause damage to the interior of the building, and can also promote the growth of mould and rot.
- Pests and animals: Thatched roofs can attract pests and animals, such as birds and rodents, which can cause damage to the thatch. If there are signs of pest infestation, it may be necessary to re-thatch the roof.
- Age: If a thatched roof is approaching or has exceeded its expected lifespan, it may be time to consider re-thatching. Older roofs may be more prone to wear and tear and may not provide the same level of protection as a new thatched roof.
