Choose a professional installation of your new roof in the Friesland region
Gebr. Roosma Rietdekkers specializes in installing new thatched roofs, both traditional and screw roofs. The management and craftsmen work together to ensure a high-quality, aesthetically pleasing finish to your new thatched roof.
Quality construction
Nowadays, you can choose between two types of thatched roof construction. With the first, the traditional thatched roof, you can still see and touch the thatch from the inside. With the second type, the screw roof, the thatch is attached to planks. This version is more modern and offers advantages in terms of insulation.
Ridge tiles on thatched roofs
The ridge of a thatched roof is traditionally made of baked reed tiles. These tiles are laid in cement mortar. We fill the spaces between the tiles in a lighter color, or we can stain them black or red—whatever you prefer. Our company uses reed tiles from the Tichelaar pottery factory, or from Meijer in Germany. We also supply copper ridge tiles upon request.
The advantage of copper ridge tiles is that there's no deterioration of the cement joint. Moreover, moss doesn't grow on these tiles.
High quality reed
Only the highest quality thatch may be used for roofing. The quality of the thatch is determined partly by the treatment, but also by the growing location and conditions. We are often present during the harvest, selecting and inspecting the thatch ourselves. Based on our extensive experience, we guarantee you the best quality.

Maintain your roof properly
Once your beautiful new roof has been installed, it's important to maintain it regularly. For example, the roof should be regularly sprayed with moss and algae control spray. At Gebr. Roosma Rietdekkers, you can take out a maintenance contract, ensuring proper upkeep for a longer lifespan of your thatched roof.
The traditional open construction for a thatched roof
The traditional roof consists of a framework of slats and beams. The thatch is attached to the slats with wire. From the inside, the thatch is still clearly visible.
