Contrary to its historical reputation, modern reed roofing is considered an elite roofing. It not only protects the building from atmospheric influences, but is also a means of architectural expression. Therefore, straw, like other exclusive materials, is most often laid in the project by the architect, and not chosen by the customer..
Bulrush (Phragmites australis) – the heaviest material among straws. One square meter of 30 cm thick coating weighs about 40 kg dry and up to 50 kg wet. It is recommended to use a reed roof for roofs of simple shape and with a minimum slope of 45 °, which is necessary for timely water drainage. The lower the roof slope, the higher the skill of the installation and the more difficult the operation. To extend the service life of problematic areas of the roof, such as ridge and valleys, wood, tiles, copper are used in combination with straw. The drain is most often carried out using French drainage, less often the gutter is installed at the level of the overhang.
Reed roof benefits
One of the most important advantages of a reed roof is that it maintains a stable temperature – warm in winter and cool in summer. Unlike traditional roofing systems where heat and moisture are retained in the attic, with a reed roof, ventilation in the attic is not required.
The 30 cm thick reed roof with a 45 degree slope meets all modern insulation standards. The thermal insulation of a well-laid reed roof is equal to the thermal insulation of an insulation 10 cm thick. Additional insulation is not required for such a roof. It is only in the last ten years that this requirement for roof insulation has been included in building regulations. As it turned out, the reed roof had this property for hundreds of years. An added value to a reed roof is its ability to effectively absorb sound.
Reed roof cost
Reed roofing is an expensive coating, despite the apparent availability and cheapness of the material itself. In order for the straw to serve for about 50-60 years, special skill in laying and modern technologies for preparing straw is required. Reed flooring costs more than, for example, ceramic tiles. But, since there are no additional costs for waterproofing, vapor barrier, partially thermal insulation (30 cm of reed cover replaces 10-15 cm of mineral wool insulation), drainage system, the final cost is competitive.
The text mentions “Reed roof,” but what exactly is a Reed roof? Is it a type of roofing material or a specific architectural style? I’m curious to learn more about it.
Is Reed roof a durable and long-lasting roofing option?
Yes, Reed roof can be a durable and long-lasting roofing option. Reed roofs are made from thatch with reed materials, which have been used for centuries in traditional roofing. Reed roofs are known for their resilience against strong winds and their ability to repel water. With proper installation and maintenance, a well-built reed roof can last for several decades. Additionally, reed roofs provide good insulation and are eco-friendly as reeds are sustainable and renewable materials.
What is a “Reed roof”? Can you provide more information on its composition and construction?
I am not familiar with the term “Reed roof.” Could you please provide more information or context about what it refers to? Is it a type of roofing material or a specific construction technique? Any additional details would be appreciated. Thank you.
