Ice infiltration leads to leak

Hi, We put a Drexel Metals standing seam roof on our home in 2010, the house had asphalt shingles before the metal roof. The roof is gambrel style with 2 dormers on front and 2 on rear. We added sno-gem snow barricades after our first year, as large chunks of ice were falling off the roof and were dangerous. The snow load would start to melt during daylight, and then freeze overnight, leading to ice building up along the dormers. Ultimately, we "think" the ice infiltrated where the roof meets the dormer sidewall and then we had water running down our living room wall and the ceiling leaking to the point where the drywall opened up. We added snow barricades to stop snow/ice chunks from crashing and destroying the gutters, but the ice is still forming. The original contractor came and fixed the damage the first time it happened. Then we were okay for a year or two, but last year it happened again and now our contractor is out of business due to illness. I am attaching a bunch of photos to show you what is happening. Can this roof be repaired? We don't know where for sure the water is getting into the house...we don't see any water damage in the attic. Because of the design of a gambrel roof it could be at the dormer (the underlayment was not wrapped under the siding according to pictures I took at the time the roof was being installed), or at the horizontal break below the dormer, or where the roof and gutter meet. Also, our first thought was insulation - but in 2010 we had spray insulation put in the attic floor between the joists and topped that off with batts of rolled insulation. After the water leaking, the contractor removed the interior walls of the dormers and added more insulation there as well.

More Info - This is a Drexel Metals roof from Harvey Building Products. Standing Seam, Trimar color: Hartford Green, purchased in June 2010. A Drexel Metals individual came to the house to assist in measuring and cutting all the panels and they laid them out and numbered them. Substrate: Ice & Water Guard was laid in valleys and water problem areas, also Rooftop Guard II underlayment used instead of black paper. But nothing was wrapped around the dormer seams. Instead, stepped flashing that was there from 1976, when the house was built, was reused. Can these panels around the dormer be disassembled so the dormer seams can be flashed better? Since they are laid from one end to another I am worried the whole roof has to be removed to fix the area around the dormers that leaks.
