what kind of metal roof are you doing?
Need advice on flashing roof extension
Hello there guys. I am trying to replace my old shingle roof with a metal one but I am unsure on how to do a proper flashing on the roof extension. My doubt is where the main roof joins the roof extension. If somebody could please give me some direction on how to proceed I will be thankful.
Here is a pic of my roof extension. Thanks

I am using the Classic Rib from Metal Sales. The one that is sold through Home Depot.what kind of metal roof are you doing?
This is the link to one of them: http://www.homedepot.com/p/Metal-Sa...l-Roof-Panel-in-Light-Stone-2313663/204255276
simple enough. id form a piece of metal that come off the upper roof, down and then onto the extension. you could use two pieces of L metal. one piece would be on top of the metal panel of the lower roof and go up the little facia, youll have to trim it to be flush with the top of the upper roof, then the other piece would counter flash it and extend onto the upper roof, laying flat. in other words it would come off the upper then down the facia and then out onto the lower panel. like i said you could do this with one piece of metal but you would have to from it. i buy form ABC metal and use the imperial rib because i found that where the side laps are they lay down without having to add any screws. not sure if im explaining it well. think of how the water is going to run, over the side of that section and bend the metal according. you might also use a rake piece there to make it look nicer. check out youtube on how-to and can also talk to ABC metal, can find them on the internet.
Roof looks kind of shallow for those panels.
What's the pitch?

ive put panels on thats pitch, they are metal not shingles. as long as theres some run off your good to go.
Thanks for your response hotrod351. I read and reread and I cant seem to get it. I do understand about the L flashing that would go under the drip edge of the extension and on top of the lower section of the main roof. Could you please elaborate a little bit more about the counter flashing. I have looked over and over online but I cant find any roof flashing like mine.simple enough. id form a piece of metal that come off the upper roof, down and then onto the extension. you could use two pieces of L metal. one piece would be on top of the metal panel of the lower roof and go up the little facia, youll have to trim it to be flush with the top of the upper roof, then the other piece would counter flash it and extend onto the upper roof, laying flat. in other words it would come off the upper then down the facia and then out onto the lower panel. like i said you could do this with one piece of metal but you would have to from it. i buy form ABC metal and use the imperial rib because i found that where the side laps are they lay down without having to add any screws. not sure if im explaining it well. think of how the water is going to run, over the side of that section and bend the metal according. you might also use a rake piece there to make it look nicer. check out youtube on how-to and can also talk to ABC metal, can find them on the internet.
I appreciate you taking the time to respond. Thanks
Yes. That extension doesn't have much pitch. I think it was like 1.5:12 or close to it. I figured if the shingles had lasted like 25 years or so the metal shouldn't be too much of a problem. I hope so.Roof looks kind of shallow for those panels.

I am not personally familiar with the product but in addition to the flashing detail in question you have a pitch change that extends several feet. Given the gentle pitch of both sections how is the overlap handled at a pitch change with that product?
I was planning on using the roof pitch break trim.
