My 200 year old TF house was built so the rafters meet the outer edge of the eaves beam and the planking seals it tightly. consequently the eaves have ice build up. I need to replace the whole roof, planking and shingles, but the rafters are sound.
My Question:
If we install a spacer on top of the rafters, raising the planking just enough to allow ventilation from the edge of the roof, will that be a good approach to the problem? Will it be structurally sound? Is there a better approach?

I'm not a TF construction person. I have a good background in woodworking and maintenance. I will probably hire people to do the work because I'm not able to take on a project of this magnitude, but I want to keep control of the way it's done. People in the past have badly cobbled repairs on this roof, and I want it done properly this time. I'm prepared to pay for the job done right.
I have a .PDF drawing of the way the roof is built if anyone wants to see it. It can be sent as an attachment. Needs Adobe Acrobat or similar to open the file.

Regards, Don
