I don't know what is was that I did not like (or did not understand more 
probably) in the past, but revisiting the tileroof macros shows me that 
all is working well, except for one little glitch:

The depth of the tile surface is given by the float parameter d. 
However, inside both Roof2() and SaveRoof(), a #local d parameter is 
used as a vector. This can generate an error when d (depth) is used for 
translating the mesh. I changed #local d into #local d1 and all is well.

I also added a normal and a finish block to the macros, to be loaded 
from outside.

The image below shows a test result using Roof1() at left and on top, 
and Roof2() at right, and the texture I built previously for the 
Gancaloon villas.
