water leaks doors and wall

Anyone leaving near or around Albany NY knows we have had severe winds and record rainfall these past couple of weeks. I have a Moosehead Cedar Log home and recently noticed that I have water damage in several places. The first being what appears to be the vertical seams on one portion of the side wall (see attached photo) the second and more worrisome is the water damage to the maple floor near and around the patio door (see attached photos) I went into the basement and pull away the insulation in that area, what I found was that the OSB sub floor appeared to be dry, however I noticed a small wet spot on the floor directly beneath the heating duct that feeds the register (that is in the photo) close to the patio door. When I poked a hole in the duct insulation water came pouring out. It appears that the water had gotten between the finished floor and the sub floor and the duct acted like a drain. What I need help with is where and why is the wall and door leaking, I know water leaks are a difficult to locate since water tends to seek it’s own path. This is a relatively new home I have it two years now and have never experienced this problem before, not even with last years record snow falls. I would appreciate any information or help regarding this problem. Thanks!

Sincerely
Bill

I see you haven't had much help. How have you made out. I'm not fam. with this construction but I would look at roof first.I would think its comming down the wall landing on the sub floor and traveling to the duct. Osb sub floor has wax or something on the top side so it takes a while for water to show thru. Good luck

I agree with Neal, look at the roof for missing shingles, or any roof penetrations but also pay close attention to any flashings above windows and doors. Look at the door thresholds and any missing caulking around windows.

Is there any warranty left from the builder?

yup, roof or flashing around the windows and doors. Look for missing flashing and/or deteriorated caulk. If it is a new house, perhaps a call to the builder too.
