hello
i'm working on fixing up a roof on an old condemned house. there are several sections that join together, and about three different pitches ranging from slight to steep. i've already framed out the sections of the roof that were too rotten. now i'm trying to pick a material to use. there are definitely some bows in the roof, and also where the different sections of the roof meets, it gets a little crazy and uneven. i would like to use a galvalume unpainted corrugated or standing seam metal roof, if it is possible with my irregular shape. my questions are:
1. is it possible to use metal sheets on a roof that is not completely level and straight?
2. is corrugated better for this situation than standing seam?
3. i'll probably have to make quite a few cuts, i'm assuming i'll do this with tin snips because i read that saws can destroy the protective finish. is it easier to cut through standing seam or corrugated? (if they are about the same gauge)
4. is galvalume corrugated more likely to rust than galvalume standing seam because of the exposed screws?
5. does it make sense to buy some sort or sealant and paint it on the cut edges to ensure it won't rust? (i'm a little worried of rust occurring where the screws go in too but i'm not sure what to do about that)
thank you! - nicole
