I am getting some water in one of my upstairs bedrooms and I'm pretty sure it's from the chimney area of the roof leaking...
This isn't my area of expertise, so I spoke with a friend and he took a look at the chimney area. He told me that the chimney was not properly step-flashed and that that is probably the source of the water.
My question is, can I step flash the chimney without tearing up the surrounding roofing by slipping the flashing into place or will I need to rip up the shingles in the area? Has anyone tried to do this with shingles already in place?
Thanks in advance!
