LEAK at dormer/roof intersect (WITH pics!)

Hi everyone!

The other day we found we had water slowly leaking in from an area where the dormer and roof intersect. It is a finished(mostly) attic, so we had to remove the drywall and insulation to find the leak.

Upon going outside and onto the roof, I noticed a slight "valley" had formed where this area of shingles are sagging.




Some info:

House built in 1912...we are in London, Ontario, Canada

Is there some recommended way of "patching" or a short-term fix for this problem until spring when I can get it permanently fixed?

This week has been very mild temperature wise so I was actually able to get on the roof semi-safely...but I have to think that the snow and winter will be returning soon!

Thanks for any info!

from the pic look like the lower portion of the roof is very low slop.
water leak under the low part and works it ways in.
I would recommend to remove 2 rows up where the top meets the lower part
and remove 2 row from the bottom and palce a ice watershield paper
remove 2 row from the top part and insert a mineral rool paper under the top part them cement the lower part and nail it to the lower part
remember whne tou put back the top row to turn the shingel around to have a clean edge and place the last row on top of the row you just place to brak the slot

good luck
