Roof Flashing Repair?

[HaRuMaN]

I have a two-story home.  I have a covered patio.  The (basically horizontal) patio roof is asphalt shingles, and the outer walls of my home are stucco.  We had a really strong rainstorm the other day, and with the wind, the rain was driving right into the joint between the patio roof and the stucco walls, and we got a leak into the house...

What's the best way to go about repairing this?

Will I have to rip up the stucco / patio roof and install new flashing?  Is there an easier way?

Sucks, I live in AZ and the first home repair I need to do is a stupid roof leak...

It rained in AZ? No wonder you have to do a roof repair.

Yeah no kidding.  It's rained like 6 Sundays in a row.  It's actually raining right now...  lol

I am trying to think of how to get around that without hassle I done complete roofing for around 7+ years.

possible to fill in the seem with roofing tar or perhaps the spray type foam the foam grows like crazy though so you have to be more carefull with that stuff.

+1 on tar.
I also lived in AZ for many years. monsoon season again?
Take a level and make 100% sure the roof is not leaning into the house.
if it not leaning into the house you a good.

If it is leaning into the house the support of the roof that connects to the hose wall is eather installed wrong of failing

if this is the problems we have a much larger problem.

if it is just the flashing , I would look at my finances and the looks of the shingels.

shingels are not that hard to replace. especially on the porches in AZ
all shingels could be pulled on a Saturday and replaced on a Sunday.
6 to 8 bundles from Home depot. I shopped in Mesa all the time.

if finances are tight I would just buy 1 gal of roofing tar. let it sit on the side walk all day. (softens it up) Very thick stuff. after sitting in the AZ sun for a day LID ON. open it up. stir well with a strong stick. carry up on the HOT Roof with a scraper put 2 or 3 thin coats at the joint between the house and roof. Be very carefull not to spill. stuff gets every were and looks like crap. About 2 inches on the wall and 2 inches on the shingles with a bead in the joint

side note: look out for Bees nests, my brother found a killer bees swarm on his porch not so long ago. he lives in Chandler

No, not monsoon, el Nino...

I'll check the level today.  Just eyeballing it, it looked like it sloped away from the house.  When it leaked, there was a heavy rain and high wind that was driving the rain right into where the roof meets the wall.

I also eyeballed the flashing, looked ok, there is tar on it now, but the tar looked pretty old.

You may get lucky and just be able to remove the old tar and re-tar the hell out of it....

I hope so.  Sounds like the easiest solution...  and I'm all for easy.
