Porch Ceiling Details
The next two photos show how the vinyl beadboard is supported along the carrying beam and the outside face of the house. The beadboard is supported along both sides with J-channel.
Other Porch Ceiling Options
If you absolutely can’t live with the thought of vinyl soffit on your porch ceiling then you can also choose from fiber-cement beadboard and also PVC beadboard. If that doesn’t do it for you then there’s always some nice cedar or fir that you can spend years maintaining….ha ha.
