We are students from the Delft University of Technology in the Netherlands. We are developing a new roof safety system for sloped roofs.
To get insight into the activities on the roof we are very interested in your experiences on the roof, especially regarding safety.
We would really appreciate it if you would fill in our questionnaire. You can download the questionnaire at http://www.omdathetkan.com/roofsafety/.
Thank you very much!
