The reed used for making thatched roofs should be one year old, straight, without leafs, sorted by length (from 150 cm to 190 cm), and dried.

The reed does not get modified while preparing it for use on thatched roofs. The main thing which has undergone changes, and normalization is the technology of mounting roofs with reed, and the criteria which the reed should fulfill in order to be acceptable as a material for thatched roofs. Years of experience in making thatched roofs led to maximizing their advantages. For example the usage of chrome-nickel wire (which is resistant to oxidation) extends the lifetime of a thatched roof and increases its anti-fire safety, thanks to its resistance against high temperatures.

The roof construction should fulfill polish norms of designing and realization. Roof weight must be taken into account. One m2 of thatch of 30 cm thickness can weight up to 40 kg – even more in case of snowing. Reed can be mounted on traditional roof constructions as well as newly designed buildings. The roofs slope angle should be more than 45°. Thatched roofs look best when the slope is about 52°. Greater slope angles also increase the roofs overall durability.

The roofs ridge can be finished using heather, reed, straw, wooden bucks or ceramic plates specially produced for this purpose.
