I am in the process of placing Master rib corrugated roofing on my home. I need to cut several pieces to fit into the valleys where the roof comes together. What is the best way for a do-it-yourselfer to cut the material without deforming it or killing myself?

If you have a fair amount to cut then go to a rental place and rent a hand held tool called a "nibbler". Failing that use a left and right set of metal snips simutainously and cut a 1" piece out about a 1/2" away from the final cut. This will roll the metal out of the way and then allow you to trim to the final cut line. Last option is to buy a meatl blade and with a skill saw cut the sheet from the back again a 1/2" away from the line. Watch the hot metal and keep it off the sheet. A sawed edge will rust where a snipped edge will not as the metalic coating is wiped over the edge of the raw steel to protect it. Hope this helps.

I have helped put a metal roof on with screws in the flats and also helped another person with screws in the ridge. What is the best way? Everyone has a different opinion.

The best way is contact the manufacturer and get their reccomendations. Having said that, some of the generic vertical ribbed panels can be installed either way. One must take into account the sheet length, slope and quality of fastener. Fastening yhen on top of the rib allows the sheets to expand and contract without stressing the fastener as much so on longer sheets it is a much better method. Having the screws on the top keep them out of the water channels which reduces the odds on having a leak from fastener failure and last is that the top location is in a much stronger section of the sheet and it helps elliminate telegraphing of an uneven substrate and dimpling from over driving of the screws.
