We have a cement tile roof that is leaking, and listed as a K3 on our house report when we bought it:

"Tagbelægningen har utætheder ved rygningen og enkelte steder langs skotrender og der er anvendt mineraluld som tætningsmiddel..
Note: Forholdet kan give risiko for vandindtrængning og følgeskader på de underliggende konstruktioner."

Our house inspector told us we need the following work done: The parts if the roof need repair:
1) the valley flashing need to be replaced.
2) the insulation in the ridge needs to be replaced with a leaf guard.

We plan to eventually change the roof completely, but need this fixed in the short-term so as to not cause any further damage.
