I goofed right off the bat when installing shingles for my garden office roof. I forgot to trim the rake of the first shingle in the starter strip. The net result is that it wasn't aligned properly.
(Thankfully?) I caught this pretty early and removed the improperly installed starter row. I still have about 15-20 holes left in the underlayment (which is 30# asphalt felt).
Should I fill these in? Or just proceed with putting a new starter strip over it?
The holes are only near the edge in the starter strip. The rest of the roof is fine.
