The major difficulty in terms of conservation is to keep the thatched roofs in good condition. Although the thatching skills are still well mastered, and the thatch is still available, conserving the roofs requires continuous efforts in terms of monitoring and replacement of the decayed grass. Financial resources are also needed to purchase the new thatch and pay the artisans, and funds are not always available on time.
The site is also affected by other threats. One of them is the shape of the roof, which has changed over the years. Archive photographs show that the original slopes were steeper, and this allowed for a faster drainage of the rain water. Another problem affecting the roofs is the changing climate, which cause more humidity than in the past.
