Is color taken into account, when roofing tile needs to be replaced ?

I have a customer with a tile roof, that is no longer manufactured. All of the salvage yards have been searched, and the tile or accesories are not available.

The carrier claims color doesn't matter, and suggest using a completely different product . Also they only want to replace 30 foot of  ridge. This means the homeowner will have 2 different types of ridge.

I cannot warranty a repair like this, and it will look horrible.  I am roofing contractor.

My suggestion was the carrier should replace all of the ridge & rake, and I can make the field tile work. They are not interested in any negotiation.

I have my work than I can handle, 98% of my work is new construction. I do not like insurance claims becuse of  problems like these. But i really cannot just bail out on this Lady.
