Couple, hopefully easy questions:
1) Is this copper flashing: http://www.lowes.com/pd_59448-205-85...ing&facetInfo=
About the best flashing material that would make sense to use?
2) Do you cut the flashing into 4 foot sections, then bend it with a sheet metal brake, then just overlap the sections and tar/nail it down?
2.5) *edit* I saw you could get aluminum and galvanized flashing pre-bent at lowes, but not copper. Is copper still the way to go? Trying to get this thing to last till I'm dead - probably 30 years. Would a building supply store be able to get pre-bent copper flashing?
3) Is this the sheet brake I want: http://www.amazon.com/Malco-MB48A-48...2256909&sr=8-2
4) On a low slope roof, is an open valley the way to go? Can you buy real thick copper for the valley?
Sorry if my questions are really basic - just want to make sure I do the valley the best way possible.
