Leaking New Shed Roof Addition
I have a small house with a 4/12 pitch roof. I built an addition in progress with a shed roof that ties into the lower part of my existing roof. I roofed it with rolled roofing temporarily (it was Feb. in N. Mich) & sealed it with something called cold patch. It still leaked. I shingled over it with regular architec. shingles a few weeks ago. We haven't had much rain until last night. It's leaking at every seam. Help!

Any help!?
I put plastic over the roof today (had to use a deer stand to get on the roof as I didn't have time to round up a ladder). Can any of you roofing gurus help a northern Michigan girl out on this one before it rains too much more? Thanks!

My guess would be that you didn't tie the two pitches of roof together with adequate flashing. Additionally, if the "shed roof" is a low pitch, water is probably wicking between the seams of your roll roofing- especially if you did not increase the overlap and tar between the lapped pieces as you laid the roll roofing.
Other than that, it's hard to give advice without seeing it.

Thanks. I think you're right. Would it be wise to consider a higher pitch on the addition, tying it in higher to the main house and re-roofing? What if I used a metal roof on the addition-would that help? Can you tie a metal roof to a shingled? Thanks for the info!

Yes, I think it would be wise to raise the pitch, and it sounds like perhaps turning your "shed roof" into a gable with a 4:12 that matches the pitch of the existing roof would be advisable.
