ᐅ Is a drip edge / eaves flashing mandatory?

Good evening,

We had our prefabricated house installed last week.
It has a gable roof with a 38° pitch, and during today’s inspection, we noticed that no eaves flashing or drip edge was installed.
The water that runs off beneath the roof tiles flows along the underlay down to the fascia board.
As a result, the fascia board is already at risk of weather damage.
The installers say this is standard procedure for the house manufacturer and that the eaves flashing would have had to be specially ordered.

Is anyone aware of a regulation or guideline that requires eaves flashing?
Because, according to my roofer acquaintance, installing eaves flashing is standard practice, but I cannot provide any written proof.

Best regards,
Marvin

What a layperson simply doesn’t know is that this type of construction is no longer up to date, and of course, no one points that out.
“Up to date,” what nonsense!

The water that gets under the roof tiles flows down along the underlay membrane and directly onto the fascia board.
The fascia board is already doomed to deteriorate.
… what water does to wood has been the same for millions of years.

Was it at least possible to review the expert report?
Yes, it was. It is the drawing of the factory standard as constructed by the house manufacturer.

Do I understand correctly that you assume a drip edge / eaves flashing is not absolutely necessary?

What are the 10mm (0.4 inches) at the eaves? Is that a gap between the counter battens and the eaves board to prevent water from the underlay from running against and pooling on the eaves board? If so, was it executed that way?

Basically, that is correct. It is also stated somewhere in the sheet metal work guidelines. Certain overhangs must be maintained to ensure water drains directly into the gutter. With proper planning and execution, both options— with or without a drip edge—are professional.

Yes, that was possible. This is the drawing of the factory standard, showing how the home manufacturer constructs it.

Does the water running off the underlayment flow down the inside of the fascia board? Or does it go around the top over the flashing(?) into the gutter?
