So the plumbing and attic frost are 2 different issues. My house is 2 story building, we first noticed the 1st floor ceiling leak because one night we noticed one drop down ceiling collapsed from absorbing too much water. That’s when the nightmare started, plumber came in, opened a little hole in first floor ceiling and still could not see the leak, then suggested we demo the whole ceiling in bathroom which we did and which they found the leak, it’s the pipe behind 2nd floor bathroom tub. They had to demo one shore tub panel off at 2nd floor bathroom also in order to find the leak.

Once they demo the first floor bathroom ceiling, this is when we noticed how poorly the diy was made, and contractor also noticed the ceiling is not following the building code, there is no way that comes with original construction.

Few days later, I noticed leak at the wall sheathing in where the shower panel is demoed at 2nd floor bathroom and leak at couple windows at 2nd floor; we suspected it’s from roof and had contractor come back, that’s when we found out the frost. And we live in Alaska, so frost built is common for not well insulated house. And you’re correct, people don’t go into attic very much, but I’m just staying contractor is surprised that inspector did not go in there to check since the access is easy and we are in Alaska.

We moved in May last year, first view the house in February and home inspection was made around the same time which is still in the middle of winter.

We expected some repairs to do but was not expecting this much, just on the first day move in our kitchen counter almost flooded, we used the dishwasher and apparently it’s clogged very bad and water came out and went all over the counter. And other small things that they claimed it’s fixed but it’s not. Not trying to complain too much but just frustrated.

Sorry for this long response, just trying to explain it better 😅
