War Wages On

After realizing the caulk near the window did nothing to stop the Heat Streak, we went back to the drawing board. Here's what we know:

  • The line in the roof lines up almost perfectly with the soffit in our kitchen.
  • The streak travels up the roof from down near the wall, because there's more melt near the wall then there is at the top.
  • The streak travels between the rafters
  • There's got to be some huge gaping hole somewhere

That's about it. Sure I could crawl up in the attic and lay down a bunch more insulation in that area, but that's not really solving the problem. Somewhere there is some gaping hole or a bunch of holes causing this and we need to find them.

Last night we looked around the wall area in the kitchen and found this.

The corner cabinet has a big gaping hole behind it and some nice cavities between it and the cabinets next to it. I used a flashlight to look up inside them to see some kind of access through the wall, but didn't see anything significant. We covered them anyway temporarily with tape and a rag. Unfortunately the roof isn't currently in a condition where we can tell if it worked.

Tonight we found another possible culprit.

That's the bottom of our tub/shower. The back of the shower is the same wall under that soffit. With the pellet stove kicking downstairs, it's totally possible for heat to travel up through this portal, into the wall and into the soffit.

I'd almost be certain this was the hole we're looking for, BUT it's not exactly near the outside wall of the house where the heat appears to concentrate before making its way up the roof. Maybe somehow in the interior wall the heat makes its way over to the exterior wall.

I guess we'll figure it out eventually.

Yo, Bob.

One technique for finding air leaks/drafts is to use a candle. Either watch the flame to see when it moves a lot near a seam, wall, gap, window, door, etc...or you can blow it out and watch the movement of the smoke.

Get your a$$ on a bike.

incense sticks work too. The streak is so big, I half expect the hole and draft to suck up small children.

I've been kind of lazy in trying to find it. Truth is, I'm pretty sure I know what it is, just too lazy to fix it. Stay tuned for a post on that in the near future.

ps. secret squirrel training has begun.
