Should these tiles be staggered? As you can see in the photo the seams are all in a straight line.

I've been told it improves the strength.
I think its called the staggered/cross bond method of installation.
However, the manufacture has the last word..

Some tile roof manufacturers allow straight bond installation with the proper slope.

You are right, a couple do I found. Can't say I've seen that done here in SoCal with profile tiles.

Thanks.

How does it keep from leaking? Just the paper?

Should be more than paper under tiles. Generally tile liner (type 30 or better) or Mod Bit membrane.

Tiles only there to protect the paper, really.

tiles today are for looks rather than function. it's the underlayment (double felt or membrane) that prevents leakage. air gap allows for runoff and drying. any old style tile job would never have straight lines as the tile itself was the protection against leaks; most installs did not even have sheathing; tiles were laid on battens secured to the rafters.

But won't the water deteriorate the membrane after a while?

If the tiles are not damaged no. If they are, yes.

Just curious what style of roof. I'm assuming a gable, but I was taught to never assume anything.
