Hello.
I have a porch with a sloping roof extending from the long side of the house, the roof starts under the eaves. I am now replacing this roof from plastic to tile/metal and will therefore also be installing bargeboards on it. The house is not very large; it's a 1.5-story house approximately 11x8m with vertical paneling, and the porch roof is 3m wide and extends 1.5m from the house. I have approximately 20cm wide bargeboards on the house, 15cm wide corners, and 10cm wide trims around the windows.
However, I am having difficulty deciding on the width of the bargeboards. Ideally, I would like them to be about 15cm, but I think this might look too wide and not match the rest of the house. A "double" bargeboard could perhaps improve the appearance. The reason I want them to be 15cm is that it also becomes an under-roof to, among other things, accommodate lighting.
Should one take two 95 panel boards and combine them to make 15cm and the upper part match the window trims?
How have/would you do (if you understand the issue, without pictures)?
