If there is a gap between the sheathing and the fascia board you may have a problem with rotted sheathing. Normally one would install a drip edge on the bottom of the sheathing. It should have been installed under a layer of felt underlayment (tar paper). The drip edge would be on top of the sheathing. Some builders skipped this step in the time period in which your house was built. They tried to make up for this by letting the shingles hang over the edge of the sheathing a little bit more than is customary when installing drip edge. The result of this shortcut method is that in some circumstances water drips, or is blown back under the shingles collecting on the sheathing. This water eventually causes rot, rusted nails, and wavy sheathing. THIS SHEATHING MUST BE REPLACED if it is rotted or YOUR ROOF MAY NOT BE SAFE. This condition should be thoroughly examined by you or by a competent builder.
You may also find that the ends of the trusses or roof rafters are rotted. There are various methods for correcting this problem which can only be determined after any rotted sheathing is removed (unless the rafters or trusses are clearly visible from the attic). Often these ends are hidden in attics by insulation.
My first house had a similar problem at one corner. We were able to scab on some 2X4's and replace a small section of the sheathing and patch the roof.
There is no way for anyone in this forum to analyze the condition of your house over the internet.
I would urge everyone to get outside help if they do not have the knowledge to do this kind of work themselves.
Best wishes on your roofing job.
