Snow on Metal Roof

I am in Maryland. When I needed a new roof I had a metal roof installed. We don't get snow every year, but when we do my foundation plantings get destroyed by the enormous snow slides coming off the roof.

I've seen those things on the edges of metal roofs that appear to be for breaking up the snow/ice. Does anyone know how hard those are to install or what they are called so I can find them? Thanks!

I may as well as the other question that's been plaguing me about this metal roof, lol.

The ridge vent is open and I have a TON of debris blowing into my attic all year. The guy that put the roof on said he has never heard of this problem. Well it IS a problem (when I open the attic door leaves, bugs, etc. rain down on me) and I want to know if there is any way to fix it. Thanks.

I'm learning already because I didn't know there were "kinds" of metal roofs and I found a picture of standing seams. My roof definitely has standing seams.

Now I'm researching baffles. It's amazing how you can find things better when you know what they are called.:wallbash:

THANK YOU!

I'm going to take some pictures. Do you want to see the outside or the inside of the ridge vent?

There is nothing there but a big air gap and the piece of metal that I guess is the cap.

If you are standing outside at night and the attic light is on, you can actually see into the attic through the gap under the cap.

I have been doing some research and I am realizing that if all this stuff is blowing into my attic, that means the cold AIR is also blowing in there. How can that be a good thing?

I don't know how to make sure my soffits are working but when I had the roof put on a few years ago I had more than one contractor check out the soffits and they said they were fine.

FWIW, for years I thought my soffits were fine. They had the vented panels, baffles along the inside, the blown in insulation was blocked off from filling the soffits. I had no reason to guess anything was wrong, but we kept getting ice dams. I pulled one of the vented panels down and 30 years of dust, dirt and moisture had formed some sort of an industrial adhesive on the inside of the vented panels and was completely blocking all the vents. It would only come off with a wire brush. I ended up having all the soffits replaced with full vented panels and haven't had an issue since. Moral of the story, just because you look up and see there are vented panels, don't assume that the holes are clear.

The first time I posted in this forum I was worried that the contractor whose work I was questioning might be here and he might see that I was criticizing his work. So I very cleverly disguised myself as a man from TX. smh

In fact I am female and apologize for the misrepresentation.

I am married but my husband does not know and does not want to know anything about home maintenance. So, I will be doing some research on this soffit problem because I assume you are suggesting that if the soffits are blocked it's causing the air to come in rather that out of the attic. I'm not going to climb up to my second story to pull off the panels so I guess I'll have to call someone out here if I think my THIRTY year old soffits need attention.

Sheesh, I can add soffit work and possibly some type of addition to my ridge vents to my need for ice breakers and gutter guards now. $$$$

Pictures of both of the ridge vent in and outside. It may be as simple as unsnapping the ridge cap, filling in the gaps with the closures and snapping the cap back on. Air getting in to the ridge vent shouldn't be happening not saying that it doesn't but it's not what you want. Thats where the hot air should be escaping.

Checking the soffits would be a great idea, it's not unheard of having vented soffit panels installed over solid sheeting.

Snow guards should be easy to install but they are kind of expensive if you use the S-5 anchors. But well worth the money to not penetrate the roofing, and the adhesive ones can and do some times slide down the slope.
