I also designed the house with 600mm eaves all round and when thinking about the wind pushing on the wall then flowing up to hit the eave - this would put pressure on the roof trusses - hence the noise. I thought it may have had something to do with the fact that the north wall is all brick and stands about 6 meters in height, then the roof. We get winds from all directions - but the house does not make any noises from any other direction. It is odd that this sound is only evident on the north wall. The slab sat for 3 months prior to placing the frame and tiled roof on, in order to give it a chance to "settle" before bearing any weight.Īll brackets to the walls and roof trusses were nailed - the independent inspector made sure that there was a minimum of 6 nails in each brace - 3 on the truss and 3 on the wall frame and that all trusses were plated on both sides. The house is now 3 years old, and there are no cracks in the plaster. The creaking sound is almost like a twisting timber sound, I guess this could be the nail movement. The floor on the second storey was glued with liquid nails, but also nailed. This did clang/vibrate a bit in the first 12 months but have not noticed it now. The frame is all timber - but I have metal fascia to which metal guttering is attached. Wow - had not thought of nail movement within the timber.
