Leak in Soffit?? Help!

About a month ago our soffit above our island starting leaking through the can light. Now, 30 days later and many many opinions no one can tell me why! We had our roof replaced 2 years ago and just had our attic insulated last week. Still leaking. It leaks when it's really cold and when it's sunny.... Does anyone have any ideas?
My husband is a Master Plumber so we were able to rule out any plumbing issues.
Please help us - it's driving us crazy!

Soffits do not leak what's above it on in it leaks.
You did not add your location to your profile so your going to get a bunch of questions on where you live at first.
Someone needs to go up in the attic to see where it's leaking from.
Ice dam from lack of insulation, leaking seal around a sewer vent, no storm and ice shield under the shingles, shingles where installed with no over hang over the soffits, rotted soffit, gutters full of ice, ECT.

We live in Wisconsin. So by cold, I mean in the negatives. When you look in our attic you can see no water damage and no wet insulation. The first leak occurred with no snow on the roof....
When you are in the attic there is no way to tell where it's leaking. We have multiple roofing companies look and they can not find a "source." We just be told it's condensation and that is why we paid $1500.00 to have the attic insulated. Today it was 27 degrees and it was really leaking with the sun out. This was the first time that is leaked with the temp above 10 degrees.

sounds like condensation---frost on the underside of the roof sheeting---melting off on a warm day.

Post pictures of the outside of the house in the area surrounding the leak---

Is the area above the soffit open to the attic?

Furnace in the attic? Could be from the drip pan.

Is any part of the can light exposed in the attic? I am willing to bet that the inside of the can is condensating because some part of the can is exposed to the cold attic. All of the warm moist air entering the can is condensating on a surface of the can that is either not insulated or only has a small amount of insulation on it.

Welcome to the Forum!

a few questions:

1. what type of insulation do you have
2. do you have soffit vents (on the roof overhang)
3. do you have ridge vents

I am going to go with air leakage, condensation, and inadequate ventilation.

You are dealing with some supremely cold temps up there right now so it is more than testing your insulation and roofing system.
