Frost In Attics: How It Happens & How To Fix It | Northface Construction

[@NorthfaceConstruction]

Hi everyone - thanks for checking us out. What questions do you have about frost in your attic? Let us know and we'll answer your questions!

So here is one for you, and as well, this is an attic with turtle vents and soffits all around. So pulling in air through the soffits and then out the vents, like it should. What happens in the winter when the air is cold has high humidity. The same kind that causes hoar frost outside. That same air is being pulled into your roof is it now. Roofs dont stop venting in winter, they work the same all year round. So if that frost can stick to things outside, what stops it from sticking to things inside an attic? Ready a ton on this, and unless you have 100% air sealing below, which lets face it, who really does, many websites say you can expect some frost in your attic. But if you have some frost, isnt that what the venting is for, to dry out small things like that. Dont think water or snow comes in those turtle vents when its windy, it happens. Isnt that what tha air moving in your attic is for, not not only vent for heat issue in the summer, but to also dry out small amounts of frost and/or rain when things arent 100% perfect.

You need eave ventilation, so air can come in from the bottom , & flow around your attic , then you need ridge ventilation so the air can escape from the top maybe even roof vents for extra ventilation to

I have a metal roof attached to the rafters. No insulation on the roof in the attic only blown in cotton on the floor of attic. The metal always freezes in the winter then melts and drops on the cotton insulation and is causing damage to the rafters. Is there anyway to correct this without replacing the entire roof? Help please

It’s winter and I have a humidifier on. I should be turning that off during the winter?

Hard to say without knowing the home. We would suggest getting an energy efficiency audit to identify the flow in your home. That should give you a baseline on if your home is moving air properly.

I am working with an A frame log home. Every winter it seems to be a problem. Very little attic space but it does have insulation stops on the roof OSB side. Can you give me advice on how to stop this condensation from happening so that every time it warms up and doesn't leak?

When you say contact a professional... What is the proper classification of professional (like ie roofer, hvac, or just a general contractor?) for the job? This winter I had this happen in my attic, caused some damage to the ceiling in a couple areas that were easy to touch up with some ceiling touch up spray.... But obviously want to prevent it from happening again. Not running the humidifier in the winter seems crazy (just because it gets so darn dry), but that could potentially be my issue. We are usually very good about leaving the ventilation fan on during and after showers. I was thinking about adding a couple whirly bird vents to my roof, but my attic has 4 static vents, and I think it may not work properly by only installing two and may just suck air from one of the remaining static vents - long story short I should contact a professional lol

don't use spray foam and spoil the roof

I have three fan that exhaust to the attic, two bathroom fans and a kitchen exhaust fan. It was like this when I bought it. Would it still be wise to run them? I also have a pretty decent size humidifier. So, I shouldn’t run that either, even if the air inside seems dry. Thanks.

Humidity levels in a house should be relative to the indoor/outdoor temperature difference. You can google it for a chart, and they make gauges to measure them.

[@An-Engineered-Journey]

Vents should never vent directly into attic, they should vent through the roof. An inspector should have caught this when your home is inspected. Excess humidity to the attic from vents will cause damage long term
