Unfortunately, however, flat roofs have been shown to cause major problems in water drainage, which has often led to moisture problems. Flat roofs are most common for smaller buildings such as sheds, garages and storage rooms. A flat roof can generally be defined as a roof with a roof slope of less than 1:40, about 1.4 degrees. For flat roofs and on buildings such as garages and storage rooms, roofing materials such as sheet metal, cardboard or sedum roofs are best suited. Cardboard roofs are the most common material that is mainly recommended for really flat roofs. A cardboard roof works well and is most often used in architect-designed houses with flat roofs. The cardboard roof requires great accuracy as the surface is more sensitive than e.g. tin Roof. Think extra about how the water drain works. There must be no stagnant water on the roof. Sedum roofs are good to use but are more expensive and require more work. The sedum roof also requires a tight construction underneath, usually in the form of a cardboard roof. Feel free to look through the CHECKLIST that is in the general text about roofs. The checklist contains tips on what to take with you, how you should act, what to think about and how you can prepare for the project to be successful. Customize the checklist according to the conditions of your project, good luck! Consult with your Woody advisor about which materials are best suited.
