Storms coming here tomorrow so I got up on the roof to take a look at what's been causing a leak and it seems that neither the people who replaced the roof last time nor the people who did it the time before had any fucking idea how to flash in a dormer window. Best I could do for now is slather some goop on but I may have to look at getting it done properly this year.
watch out for mold, its a real bitch to remediate. best to tear out more than whats needed to make sure you dont miss any moisture damaged structure that will come back to bite you (possibly years) later.
btw bleaching wood to try and kill mold and such doesnt work, the spores will survive (they go pretty deep and a surface application of bleach wont reach that deep). you need to seal any moisture damaged wood once its dry. hard surfaces can be disinfected with bleach though.
wet sheetrock, insulation and rugs.. just trash em.
get something like this (random amazon hit)
