Re: Mold in my attic ceiling, water in my house...help
After 10 years, not sure who you think should be liable besides yourself. Homes require maintenance, if they don't get it, they start having problems. Instead of pointing fingers looking for a fall guy, your time and energy would be better spent finding out what the problem is and correcting it, then mitigating any mold/mildew issues that have resulted from it.
Without a site visit to inspect the structure, there is no way that anyone can definitively tell you what is wrong or why there is a problem. A roof leak can have any number of causes beyond faulty installation or materials. A squirrel or bird may have chewed a hole, a commonplace problem for those with a cedar shake roof. Leaf build-up in a valley could have rotted out flashing. A previous storm could have damaged the roof.
I would recommend starting with your insurance adjuster to assess the damages, however DO NOT accept any settlements until you've had at least 3 general contractors familiar with roof, framing, and drywall submit bids for repair.
One last thing you can do is to talk with other neighbors in your neighborhood that have the exact same house to see if they've experienced similar problems that may have a common cause. If there are others, then, and only then, might the builder be liable.
