Metal garage roofing question

[SloMango]

I am about to pull the trigger on a metal building and have a question. It will be a 30x31 with the doors on the side instead of the front like normal. They asked if I wanted a vertical roof for $1100 extra. Will having a regular style roof help with rain/snow run off vs having a vertical roof dumping right in front of the doors? Thanks

Well the doors are always on a “side“ in my opinion. The front is a Side so we need some clarification on “side” or “front”. I have never heard of a vertical roof...or a horizontal roof, or a regular roof. Before you sign a contract, you might want to define these terms.

A drawing or sketch would also help the discussion.

Vertical/horizontal refers to the direction the ribs run in the steel panels. The only place I've seen horizontal is in metal carports/light square tubing structures. Either way, the rain will run down hill and off the edge of the roof. If you were in an area with heavy snow, I would go vertical so it would slide off easier. But you're in NC so it's just an aesthetic thing.

Pictures would be nice.

I was ask the same question when I was researching all metal bldg. Means less grits and purlins to make it little cheaper. I guess it works since its an option but I was concern about wind,and panels rattling and less strength for frame.

Hopefully this link should work and show the difference

Are you talking horizontal or vertical panels or roof shape? Whichever it is you don't want rain off metal roofs draining above doors. It collects along the panel ridges and make concentrated water spouts off the drip edge like a hose. You get wet real quick compared to a gable that drains off to the sides. I have a house and a commercial rental building and learned this when changing from concrete tile on house and singles on commercial bldg to metal. Go find a metal roof in the rain and stand under the drip edge to see what I'm talking about.

I have never seen that installed that way in my life. I can’t see how it would be of any benefit at all. Definitely want them running down so no water collects. And if possible yes have it run down on the side where the doors are not going to be if you need to get out of the garage after it snows

Horizontal roofs are less expensive and faster to install which makes them popular. They are supposed to be built on a slight slope so the water runs off one end. Not very practical in snow country. When I was still running cranes I loved those cheap carports. I made lots of money picking them up off of cars and RV's when they collapsed.

No way would I want them run horizontally.


Sorry but this a poor building tactic in my opinion, just another way to cut corners for the almighty dollar. No different when these metal carports are built on an oversize slab for the convenience of the contractor only to leave the owner fighting water coming in under the walls in the near future.
