EnviroImpact Help

Hi,
I really need help on the following questions:
1) In order for me to perform a life cycle assessment I would have to change all the currently assignment materials (within the Apache database) and try and match them with similar materials listed within the IMPACT Life Cycle Assessment (LCA) database. To have a representative LCA, these newly assigned materials have to have the same thermal performance of the originally assigned materials (i.e. U=0.18W/m2K) but also the same material types (i.e. brick cavity walls that are insulated). All the pre-set wall constructions of the LCA database are a default of U=0.35W/m2K.
My question is: how do I customize a material's thermal performance within the LCA/LCC database?
2) Why are there no preset material constructions for Roof (there is only for external walls/windows etc.)?
3) How do I assign material to non-thermal constructions? I have managed to assign it to all of the beams/columns/lintels etc., but for some reason, not all of my structural elements show up within my EnviroImpact life cycle calculation
