Low slope garage roof problems

I am helping my parents re-do their garage. I want to insulate it since I will be doing the siding and simply want to cut down on the draft they're getting when it's windy. It doesn't pay to do so until I can fix the roof though. We have a very low putch roof over the garage that extends over the dining area and the addition (master bedroom). It seems every 3-4 years we have to do a total new roof and every year we're back up there patching it.

I was just up there getting another patch job in before the cooler weather hits and a few of the spots requiring patches reveal the lumber under needing replacement as well. They have told me that next year they are redoing it, I don't want all the other work being done to be futile though if it stays damp all winter. What options are there for a low slope roof in central WI?

Looking for both DIY possibilities and professional options to look at. Thanks in advance for any advice!

What's on top of the roof and just what is the pitch?

You can shingle slopes as low as 2:12 but its a good idea to put ice and water shield over the whole thing first. You also want nice clean sheathing for it to stick to.

Don't most shingle manufactures state a minimum of a 3/12 pitch ?

It would help to know the pitch of your low pitch roof. Pics might be handy - http://www.doityourself.com/forum/el...your-post.html

Garage

It is a 1/12 pitch. Just measured it, 24 foot wide, 2 foot rise. Currently rubber rolled roof. Trying to upload a picture, work computers are making it difficult.
