I've been experiencing similar problems with my roof leaking, not sure if it's as urgent as this. I have been looking at this one contractor but wondering if anyone can recommend somebody for roof restoration sunshine coast who they would trust with their own roof. I did think about having a go at it myself but it's probably not worth the risk of stuffing it all up.
EIFS is not water proof, it takes on water in a rain storm. Most installers today are smart enough to use a water managed system which allows water to exit the system at a drainage channel at the bottom of the exterior walls. Yours are back wrapped, with no drip. Bad design, IMHO. There are no good shots of the valleys, or how the windows were done, but from a distance, the detailing looks deficient.
