BTW, learned more about this from Matt Risinger and his team, and channel. Great guy and ppl he works with
I cleaned a home last winter with that same issue in Elgin. Never seen that type of staining before but it cleaned as normal with chlorine solution.
You will likely have that job every crazy cold winter. Keep me posted.
If the closed cel spray foam was sprayed to bottom of roof decking and rafters etc….my guess is, no air gap at all, whereas before the foam, had air transfer; so now that air circulation can’t circulate “beneath” roof and around your getting the high heat humidity gunk that is being trapped underneath decking and foam and only way for it to escape is thru vents in soffit or siding itself. So, way to fix is need to add furring strips to make a grid on top of roof decking and behind siding to allow for air circulation and once done, should solve the problem.
Great observation. It makes sense.
@@ChicagoRoofer thx, appreciate comment/reply
Thank you as well
Simple first sun can penetrate up to 6 ft of snow second if there is not a proper vapor barrier there will be condensation . Now back to first that is a perfect ice dam roof when you have a pitch transition with thermal melting . You can vent the hell out of the roof but if there isn’t adequate soffit venting you are screwed
The home has spray insulation in the rafters. But no spray insulation at the eave or in front of the dormers. The intake is only allowing air to travel at the eave of the roof. There is no exhaust.
@@ChicagoRoofer horrible! Everyone getting all caught up on spray foam like it’s a miracle solution.
Granted it does 2 in 1. Provides insulation as well as air sealing. Also has a better R value per inch installed.
But it’s not perfect, and to me the idea of not having to vent because you spray foam is ridiculous.
Regardless how much better in terms of performance on paper it can seem to more traditional insulations, it will still lose heat.
Brining in outside air to bring attic space to same as outside is still a good idea.
Myself if I were to go spray foam (wanting to only fill the rafters to maximize useable interior space) still just run a row of rafter vents bottom to to
You’ll only lose a freaking inch of insulted area and will then get rid of ice damming and condensation.
If your worried about losing that inch so much run a furring strip on the backside of your rafters before dry walking the interior.
This will give you the insulation thickness you want, while still providing venting, and your only losing an inch of ceiling space like you’d ever notice that.
Regardless of type of insulation, R value installed or any of that, it just means it’ll slow the transfer down more but not completely.
I did respond before watching the vid. Definitely a lot more going on here than originally thought.
I was more replying to the fact of no venting.
But yes. Hot will always meet cold. It will condense. Condensation will form. Mother Nature always wins.
Probably why the gable soffits were weeping. Heat loss from the foam insulation hitting cold winter temps.
I had a guy who replaced a good roof twice as he thought the roof was leaking due to ice damming.
Was cathedral ceiling. No proper venting. It leaked while it was still a degree or two above freezing. All depends on the humidity and indoor temps.
Well put! I think that would work best too. Great idea with the firring strips too
I know I'm late to the party but I've seen this with felt paper underneath. 90% chance. 10 seconds in i saw it. Usually happens when people are anal and ridiculous with their indoor temps and "efficiency".
Woops you just said they had spray foam probably to the rafters. Bad idea. I prefer doing a poly-iso and either sticking it to the interior of the rafters and sealing the joints or in between leaving a gap for ridge venting. The best answer at this point, at least to attempt, is to seal off the attic from the lower levels. This all depends on if they're using the attic as living space. If so, damn that sucks for them. Those shingles and tar paper won't last.
Neat to use thermal in that really got to the issue unexpectedly.
Interesting observation! I do agree that a lot of people want to go above and beyond to make their home energy efficient. But, doing that makes sense. Why would anyone want to lose money through inefficient spaces?
@@ChicagoRoofer true that, it came out wrong. What I was saying was really more insulation without thinking about how it effects the entire envelope. I have seen people go-to great lengths to create efficiency by using the "I need more" because it must be good" without worrying about how it effects the complete envelope. Kinda like what I just did with my previous comment...lol.
Great input and observations! Roofing and generally construction isn't merely nailing things together. There's a certain science to why things are done a certain way.
