Hi, I am a structure engineer and I have dealt with lots of buildings, ranging from concrete, steel and also timber. I also have lots of experience regarding timber structures, not limited to roof. I have done several tasks from freelancer also related to timber structures. I am definitely sure I can help you with your task and I hope we can work together well. I can show you some of my designs and calculations that I do for them if you want to. I am looking forward to hearing from you. Thank you for your time.
