Existing roof is asphalt shingle 7:12 pitch, no valleys but front elevation poses some challenges. I have a contractor who says to install 24 gauge 16" standing seam over the existing shingles but I'm concerned with flashing issues. See attached photo. Site A is gable to ridge transition. Site B is gable to hip transition. I'm not able to visualize the flashing at these sites that would be watertight and attractive. One company who only does asphalt shingle roofs told me my roof is too complex for metal installation. I'd like to see a photo of the metal flashing on a similar roof. Thanks in advance.

I am not a fan of going over the top. More important than those specific areas are the roof to wall intersection. What is he proposing there? The areas that you indicated could be addressed by cutting the rake boards back slightly to allow for the metal to pass underneath.

Thanks for your quick reply. The metal over shingles is also a concern, contractor will use synthetic felt over shingles. Going to remove siding, install panel then sidewall flashing then replace siding. I'm not so concerned about the clearance of the standing seam panel under the rake boards. It's the geometry of the piece(s) of metal flashing that will go over the gables and then over the ridge or hip.

It can all be hand seamed together. It will be a bit of a jig saw there but if the guy is good, it will work.

Here is how it turned out. Not as complicated as I imagined. Roofer did a good job but I felt the need to supervise as the contractor (license holder) was never on site. But that is another story. Another question I have will be in a new thread.

Looks clean from the small pictures I see.
