What does a vertical roof mean on a carport?

The roof panels run from the ridge down to the eave rather than across the frame. That lets rain, snow and debris slide off instead of collecting in the panel seams.

Is 20x20 ft big enough for an RV?

It fits most Class C motorhomes, travel trailers and tractors with room around them. Measure your vehicle's length, width and height including roof accessories before committing to the pad.

Does it come with sides or walls?

It is an open-sided carport. The structure is the steel frame and roof; walls, doors and enclosures are not part of it.

Can I install it myself?

These steel carports are typically assembled from a frame and roof panels, but the 20x20 ft size makes it a multi-person job. Many buyers have a crew install it and pour or level the pad first.

How does it handle snow?

The steep 120-degree pitch helps snow slide off, but how much load it carries depends on your local snow loads and how the frame is anchored. Check the frame specs against your area's requirements.
