In the Object Depository under 01 General > Custom Labels there is a Label: ROOF AREA ,SLOPE,MAT. LABEL, which might work for you. I tried scripting a label to read roof slopes before, but it only read the slope from Single-Plane Roofs (not Multi-Plane) so the Label may be of limited value. You might also check the Bim Components web site.
