Wet or Dry Snow Tuesday? Structural roof issues
Posted on 1/19/25 at 11:03 pm

Will this be the heavier wet snow we receive Tuesday or the drier flakier kind? Wondering if we should be concerned about potential roof collapses if it will be the Wet snow, and possible 12 inches of accumulation occurring.

I'd be very surprised if it were a dry snow but hopefully it will be so

Are roofs built in places like Minnesota more structurally stout than in the South?
Somewhat serious question, but I'd doubt 12 inches of snow, wet or dry, would cause a roof to collapse.

No roof collapses, but gauranteed roofs that will leak. Many roofs in the area are naturally weakened due to hurricanes. Plenty roofs that are aging too and will leak due to this snow situation.

How do you all build your roofs down there? Can’t take a little snow?

You'll want to pull the snow off if you get a lot as you will likely get ice dams on the eaves which cause massive leaks due to water pooling. I'm assuming houses down there are not designed to mitigate them.
At a minimum I'd suggest pulling it off the eaves.

I dealt with the last time we got snow….massive roof leaks is an understatement!

We rarely if ever get the amount or snowfall expected. So it's a legit question especially with aluminum structures such as patio covers. Yall prepared for a cat 2 hurricane up there?

We like to build them in a way that forces our insurance companies to have to pay to replace them every so many major weather events. We then like to bitch about why our insurance companies put so much effort into investigating/questioning if they should replace them; and we they ultimately do we will then bitch about the rising costs of insurance

Depends on how good your insulation is in your attic. If you have good insulation the snow will stay on the roof, if your insulation isn’t particularly good it’ll the snow will melt.
We used to drive around Pittsburgh when I was a kid, during winter and my dad would point out the houses with poor insulation because there would be bare spots on the roof instead of snow covering them.
But to answer your question, there’s nothing to worry about, your roof will be fine. Especially if it’s wet snow, the more weight the more gravity does its job and pulls the snow off the roof, unless for some reason you have a flat roof.

When you get at least a few inches of fresh snow is a good time to see how well your roof/attic is insulated, compared to your neighbors anyway.
Im guessing homes in LA aren’t insulated like homes in the arctic but you should see a fairly even melt. If you see one area completely melted, and you’re reasonably sure its not from sun shining on it, than that area is poorly insulated. Maybe take pics so you can address issue at a more convenient time.

Go shovel it off baw
Show some salt up there

Houses in areas that receive regular heavy snow are built with particular structural snow load requirements.
I don’t know how much more substantial it is vs the south though

Maybe they just left their attic doors open, to let warm air in, so the snow would melt and not cause their roof to collapse.

Man, I’d hate to see that power bill.

I'm wondering about the older flat roofs on a lot of commercial properties built prior to the 80s. They were definitely not designed for snow loads.

Are heat pumps pretty popular in Louisiana and the lower Southern states? If so, those bills are going to be nuts even without that. Snow pack just naturally makes it colder on the other side of it.

Yes, and in my experience, they’re at their worst when you need them most.
