Bathroom vents that goes into the attic is supposed to be connected to a roof cap, but the ones in my attic are just placed under roof vents. Here are some photos:
Is this an acceptable solution? I would think not, since moist air can accumulate inside the attic and cause mold to grow.
Can this be corrected without having to walk onto the roof? If yes, then I can try to fix it myself. If not, then I will hire someone to do it. What type of contractor should I look for?
