major run-off on garage roof = disaster

About 15 years ago my carport was replaced by a two car garage. It is nestled in the L-shaped area between the family room and kitchen. No surprise…the water run-off from those two original roofs flows directly onto the garage causing problems. The 45 degree corner has been the worst area, leaking with every rain. The water damage has wrecked havoc with the underlayment for years. It has finally deteroriated to the point that it must be fixed this fall……question is….HOW! Oh, and did I mention that there is very little sloop to the roof?
All the existing roofs are composition shingle (10 years old) and one layer of heavy duty tar paper. It is understood that the underlayment must be replaced in spots. There are a few options being discussed:
Replace garage roof with rolled roofing….
Rebuild the peaks of the two exisiting roof and incorporate the garage roof so it is one continuous plane.
Replace roofing with a metal roof.
We would like to do the work ourselves….have not ruled out the rafter rebuild…thoughts anyone????

What is "little". 0.5/12, 3/12?
A picture would help.
And reframing to get ride of the problem area is always a good idea, IF it is practical.

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.

Do that one.
I can't begin to offer constructive help without a picture. Your verbal gives me a couple different imaginery settings, neither good design in the first place.

Well put. Should be one of those truisms that everyone knows, like "measure twice and cut once."
If you write back to this thread here that you have taken some digital pictures of your setup, the good folks here will give you help in getting the picture uploaded into this site - on the chance you've not done so before...
Do try to keep your pictures for posting here resized down to the 200 kb level. Plenty of folks here CAN open the 1-2mb JPGS but some key folks here are living in remote locations without broadband internet, so they're stuck on dial up.
Good luck.
