paint turning pink in garage
I am having a problem in my garage and I hope someone can help me. My garage is below a master bedroom that is about three feet shorter than the garage so there is a bit of roof right over the front of the garage and also on the sides of the garage.
A year ago the garage's ceiling paint bubbled and we started getting some water dripping in. I had a repair guy come out and he went on the roof with a hose (which is relatively new- roof was replaced in 2005) and he found that water was getting in between the vertical cedar siding and the horizontal trim. He caulked all the areas (I think) and water no longer came in. I had the ceiling repaired a few months later.
As soon as the ceiling was repaired I started getting water marks at the junction of the wall and the ceiling and down the corners of the garage. I called the guy back out and he came out and checked his work. He said the repair was fine and he didn't know what was going on. He then painted four walls of the garage at the junction of the ceiling and wall and said to monitor.
As soon as he did this I noticed that on days when it's very cold the paint turns PINK. As it gets somewhat warmer the pink goes away but there's a yellow tint to the paint and you can see all the brushstrokes. It's hard to tell if the areas are WET when they are pink b/c it's so cold out and the garage is not insulated.
I trust this guy since he has done all my other home repairs and he's even the one who did the roof and I have never had any problems. He just doesn't seem to know what is going on and I need help!
Any idea what is going on here?
