New roof-visible nails . Is this normal ?

[Sam Zawatsky]

Hello,

I had a new roof put on this week, and I noticed when I did my inspection that there were areas at the peaks of the roof that there were 4 nails driven in, and then sealed with a clear sealant. Is this normal? My experience has only ever been with gable roofs up to this point, so I am not used to seeing hip roofs and how they are roofed. I did notice some sloppiness from the rest of this job, however, so I do not completely trust the roofing contractor to tell the truth or correct information. In one of the pictures, it shows where they forgot the clear sealant. Is this a standard practice to have exposed nails on roof leaks or ridge vents that are then sealed with a clear sealant?
