这张照片怎么了？
Here’s a place to post pictures that show building practices that violate the laws of nature, building science, good practice, common sense or any combination thereof.
I’ll start off with a few from my extensive collection. See if you can describe the mistake. Correct answers will earn you good karma (and maybe some “Helpful” points).

我跟随一堆有执照的MD家庭装修承包商。
如果没有破产...请勿修复！
My favorite is the structural foam repair.
你确定你想去这里吗？
1. The wrap is not flat against the sheathing, creating a condensation trap?
2. Flashing continuity has been comprimised?
3. Shouldn't the siding cover the metal roof?
4. If I was an insect, thats where I'd be. Penetration sealing notwithstanding.
5. Looks like caulking. Shouldn't that be framed out at an angle to shed water? Looks like water could pool up on that window.
6. I believe the drop edge should go over the wood.
7.附加闪烁有什么问题？只是Josh'n ya！
Answers from a rookie
Open web at top block course the favorite here~ client was wondering where all the water was coming from ////\\
You really have to click on these and enlarge them for the full effect.
1. The wrap is not flat against the sheathing, creating a condensation trap?
不,比这更大的问题。
2. Flashing continuity has been comprimised?
您可以这样说，但是缺少什么？
3. Shouldn't the siding cover the metal roof?
Siding not yet replaced, but there's another issue.
4. If I was an insect, thats where I'd be. Penetration sealing notwithstanding.
这里缺少什么？
5. Looks like caulking. Shouldn't that be framed out at an angle to shed water? Looks like water could pool up on that window.
Yes, and yes. A bay window with no bottom bracing (so it sagged), and no roof (pooled water and leaked).
6. I believe the drop edge should go over the wood.
Yup (drip edge, that is) and so should the rake flashing (whatever that's doing there) and the shingles extend over the rake trim.
7.附加闪烁有什么问题？只是Josh'n ya！
维修工作的地狱 - 也没有关于烟囱的板球（但您在这张照片中看不到） - 长期缓慢泄漏到下面的绝缘层和干墙。
嘿，罗伊，那个干墙桶埋在地面上是什么？那是用于漏水到CMU核心的干井吗？
Robert, it looks like you have a problem with incompetent flashing details. Why are you so picky? Just live and let rot.
1. - the window flashing is going to drip down behind the shingles. that's awesome.
回答＃1〜尽管我从未使用过这些东西，但在我看来，屋顶线上的襟翼（缝隙）应较低，以便可以将它们编织在木瓦训练下。而不是安装在窗户法兰胶带上并闪烁。
Thats not a bucket Robert , it's a big checker~ for checkin things out. You mean you don't have one of these in your tool box !!
Typical North Texas Construction
What Thermal Bridge?
不...没有任何淘汰
Reglet
Standing seam panels should have been panned up higher. Counter flashing should be installed over the panned edges, and should be made of the same material as roofing panels, not copper (Galvanic corrosion potential). Can't tell from the photo if the copper flashing is tucked up under the siding a least 2" as it should be.
Picture #2:
是的，在砂浆接头上躺着或反弹。
RustyJames,
再次。除了“反弹”除了从护套板到金属屋顶锅下的屋顶板的比特烯。
Either similar metal counterflashing or some other compatible flashing can be used as long as the vertical leg extends up several inches under the siding. The problem with using metal flashing at this point is that the roof pans weren't turned up far enough to prevent wind-blown rain from penetrating.
I used more Grace butyl tape to complete someone else's job. This was just one of many repairs I had to make to this new standing seam roof after the contractor refused to do any more repairs to his inadequate and incomplete job.
屋顶承包商还通过3英寸的管道通风孔进行了轻微的泄漏3英寸的管道。
约翰，那些真的是车道还是被改变了？

Now here's case of unintended consequences with a positive spin.
没有什么比从屋顶上悬挂的冰柱更迷人了。但是我们都知道有问题的冰坝可能会有什么（我确实会偶尔会泄漏这些污染物）。
但是，由于我必须通过在木炉上融化雪来提供冬季洗涤水，而且由于一英尺的雪可能会融化至一英寸的水，因此让我的屋顶预处理到冰上融化的冰中要有效得多。到水中的90％。
P.S. I also pre-heat my cordwood before putting it in the wood stove. It allows it to burn more efficiently.
