Noobies VÜ

I think I figured out why it has been so warm this winter. First, I'm not complaining about the heat, it is marvelous and allows me time to ride my motorcycle in comfort, but it has been really warm when compared to January and  February of past years.
With my roommate's help this last weekend I think we discovered why.
On my continuing trials and tribulations of my home and the corner cutting and what-the-hell-were-you-thinking modifications by the previous owners, I have found one more.
We had some good rain last week (I love the rain, but I've grown to fear it lately) and I am aware that when it comes from the correct direction my roof tends to leak a little bit. Not a lot, but enough to warrant a bucket in the sunroom. I'm actually quite happy that it is localized in the sunroom doorway but it's still not cool. At all.
Well, imagine my surprise when I am sitting on my couch and there is this odd pop-pop sound coming from the cushion beside me. I glance over to see a receipt roomie had left on the couch jump slightly. I'm like... wha...?
Just as I start to ask said roomie, who was sitting on the floor- don't ask, he just does that, what he left on the couch that was making that noise I realize it is a drip. Holy shit. I've never had the ceiling actually leak in the main part of the room, but I look up and I could see water collecting at a seam in the drywall on the ceiling. Not cute.
Sigh. Fortunately, beyond a few drips that sectioned dried up quite quickly, then I could hear the bucket in the doorway start to fill up. Double sigh.
I had to resign myself that once again I was going to have to tromp up unto the roof that weekend and see if I could figure it out.
I am pretty sure the half-assed way that the a/c unit was installed had everything to do with it. I just have to wonder if the homeowners did it themselves, or if they paid someone to do it. Regardless, it is ridiculous. I can already tell I'll have to do something to correct it in the future. I just love when people half-ass things figuring they'll fix it later, or better yet, allow someone else to fix it when the house is foreclosed on. psh.
In my inspection of the A/C unit I discovered a nice gaping hole (try a good half an inch at its widest) beneath where the ducting ties in. I didn't think a lot of it, the ducting itself is flexible tubing so I assumed the square ducting was simply enclosing the other stuff, I had corrected some similar gaping above with some aluminum tape but I hadn't looked below. I should have. I can only assume due to the way they installed it, the unit has settled and caused the gap to open below. Well, roomie passed his hand underneath when the unit turned on to heat. Oh joy. One vent is the cold air return, the other, heat. Well both of them sucked and blew. I think we can pinpoint my house as the cause for the warm winter as I have apparently been heating the outside for months.
It's almost funny, I went upstairs to figure out a water leak and discovered another kind of leak. Well a bunch of aluminum duct tape later, hopefully that part of it is corrected. Now I still have to figure out how to correct the water leak. Pretty sure the 2x4s nailed into the roof have a lot to do with it. It just kills me 2x4s! Then there is a bit of flashing that they used that I assume was meant to direct water away, but it is so stupidly put in that instead it directs it under the 2x4's where it collects until it seeps into the house. Idiots.
I had hoped to post some images of it but I didn't think to take them until after I fixed stuff. We put some flashing around the the sides of the frame and thus far, almost 2 months and a few storms later, I can say that I think the problem has been at least mostly addressed. For now.
