Do these screw holes in the cap shingle need sealing?
Builders reps answer was “That’s how they did them all.”
Thanks

Just adding more questions to your post because I do not see many tile roofs in my area. The existence of that mortar combined with the holes causes concern for me. Are they having trouble keeping these tiles in place?
Same here…
Aren’t those holes for fasteners to be driven through?
Just speculating here, but that mortar indicates these ridge tiles are not properly attached or they rattle. Tiles are water shedding and some water under the tiles is expected. Therefore the condition of the flashing and underlayment is much more critical than a few holes IMO.
Not exact, but a quick search reveals this…

Make sure you call out that cracked mortar

The mortar is used as flashing for tile ridge caps. The caps are usually attached with screws and/or manufactures recommended sealants.

Thanks Peter. I did a little digging and see that mortar is common in ridge cap installation. I haven’t found any with holes as of yet 
No issue.
Here is one from yesterday. (But this new home had about 15 cracked and broken tiles, and the builder blamed it on the gutter guys)

He mentioned the gutter guys before he saw my photos

I don’t see many either in my area, I would think the holes are located pretty high up on the cap’s to be weep holes, I’m not seeing how they would drain.

Thus my opinion of being for fasteners.
