If what you want for a simple rectangular profile is to angle them for installed overlap, it's not difficult, but you need one more piece of information: the distance along the roof slope between courses, or what might be called the "pitch" or the "exposure."

Draw the tile profile horizontally [red on the left], with its corner on the roof slope line at point A.  Draw a Circle whose radius is the tile thickness [white], down the slope of the roof by the exposure distance.  Rotate the tile profile, using point A as the rotation base point, and for the rotation angle, use TANgent Object Snap to get point B -- the result is the uppermost red tile at right.  Copy multiple times [or Array] that rotated tile down the slope, spaced at the exposure distance.  Erase the temporary Circle.

Extrude the profile into a 3D Solid if you want it modeled in 3D.  Copy or Array them into rows on the roof.  You would presumably need to Move every other row of resulting tiles by half the tile width.

These should be rather fundamental concepts.  I wonder whether you need to get some basic instruction in the use of the program, before embarking on modeling a building in 3D down to the level of detail of individual roof tiles.
