    find source of leak. if in the visible metal sheet, use matching caulking. consider brown caulking under or along shingle edges facing valley metal. there may be a clear spray

    available for difficult locations.

    We had a leak around one of our sky lights and fixed it by applying a 6 inch strip around it. That was over 5 years ago and still dry.

    You could try Flex Steel spray or a product called Through the Roof. Both will seal the area, although Through the Roof was recommended by my neighbors roofer.

    Don't use Flex Seal. It breaks down from UV sun rays. Best solution is the gently raise the shingles in the valley and liberally squeeze some rubber roofing caulk under the shingles. Stays flexible since the sheathing, flashing, and roofing move differently.
