I have about 1900 square feet of roof area over loggias (porches and walkways). This area is very low slope (I'm a new to all this so don't know how to calculate slope). The house is roofed with new shake; the low slope areas have a supposedly waterproof membrane applied under the shakes. However, these areas leak like a sieve and nothing my contractor can do will stop it. He doesn't work with metal.
I've been told that metal will work so I figured I'd better ask the experts. I have a number of questions:
1. What kind of metal (if any) will work on these areas?
2. What material should be placed under the metal?
3. What issues should I address to ensure no leaks? For example, I've seen posts about being careful with screws. Are there other issues?

There are some metal roofs which can be installed on low slope.
One is a mechanically seamed system which is seamed with a power seamer after the panels are installed. These systems are available from commercial roofing contractors.
The other option would be a hand-formed and soldered system, usually available from a sheet metyal shop.
Exactly what is installed beneath these will be specified by the roofing manufacturer.
Another option for low slope consists of one of the various single ply rubber or PVC "flat" roof systems which are pretty readily available.
Shakes on a low slope will not work, as you have found out.

Thanks so much for your recommendation. I've not heard of rubber roofs; I've googled it and looked at various sites but can't find one that has any pictures. How does this stuff look?
Also, do you have advice regarding price ranges for the two different metal roofs you suggested?
My original contractor put on the shakes (3 years ago) and gave me a 10 year "no leak" guarantee. The shakes started leaking the first year. He has agreed to remove the old shake and tie in the new roof material with the shake that will remain at no charge. However, it almost seems like he should be helping me out more with this expense since he put the wrong thing on to begin with. Your opinion on that?

It is against our association antitrust guidelines to answer questions related to price.
If you contact individual member manufacturers direct, though, they can help you get those answers.
Search for single ply roofing and you will find more info on the other products I mentioned. Aesthetically, they look like flast sheets and are available in a few basic colors usually.
Regarding your deal with your roofing contractor, that is a question you have to answer for yourself and then make your own decision as to what you will accept. If you feel that what you bought from them was a "roofing solution," then you have to decide whether that is what you received.
