Jason Shapiro took the plunge and invested in more insulation for his house: blown cellulose for his attic and dense-packed cellulose in the exterior walls. No doubt he’d like to be enjoying a warmer house and lower energy bills. Instead, he’s dealing with a mess.
夏皮罗写道：“我们现在有大量的降雪和冰冻的降雨，今天我注意到墙壁上的窗外套管的泄漏被密集包装。”a Q&A post at GreenBuildingAdvisor. “When I went up on a ladder to look at the gutter, I found a significant amount of frozen cellulose protruding from a gap between the slate roof tiles and the sheathing underneath.”
看来纤维素从外面扇动水分并允许它进入墙壁，但是为什么首先在那里过多的纤维素呢？Shapiro说，在将纤维素吹入之前，将泡沫隔热挡板放在每个after之间，并用喷雾泡沫密封顶板。
“The soffits appear to be filled with cellulose that is poking out through the vents, and which can be easily seen from the outside of the house,” Shapiro says. “I am also able to reach up through and behind the gutter and under the sheathing and can feel a large amount of wet cellulose. The contractor is saying that there must have been a problem with the roof that allowed the cellulose to communicate to the exterior in this way. He is also saying that there is no need to remove the wet cellulose because it is treated with borate and will not mold.”

Pull down the soffit
I suggest pulling off a section of your soffit to see where the insulation is coming from. It should be evident if it came from the wall or the roof. It is the insulation contractor's responsibility to remove and replace wet insulation as well as repair any damages from the poorly installed insulation. Be careful in allowing them to do work beyond the insulation task, if you have insulation installers out there removing and replacing soffits, 9 times out of 10 they will do a shotty job and you will need to get it redone anyway.
获得第二意见。找到可以评估您的损害，原因和解决方案的总承包商。这将帮助您了解绝缘安装程序需要做什么。从承包商那里获取损害赔偿的报价，如果需要修复或更换区域，例如拱柱，壁板，屋顶或排水沟，则在绝缘安装程序的功能之外，将是绝缘安装程序的责任向您的承包商支付维修费用。
It is a messy situation dealing with poorly done work, and likely you will end up paying for something out of your pocket, but you most definitely do not want to leave any sort of water intrusion issue alone. It will not dry out, and nothing in the building world just goes away, it only gets worse. Down the road you can end up with rot, or water intrusion issues that make their way into your home.
Obvious previous leaks.
If there weren't openings in the assembly to start with, there wouldn't be wet cellulose. Sounds like the baffles sealed the deal, either weren't wide enough, or not tall enough, and/or the installer was blowing sloppily. Cellulose obviously shouldn't be in soffits or against ANY skip sheathing.....missing fascia?
