Metal Building Roof Styles
The roofline shapes how a building drains, how much headroom it has, how it ventilates, and how it looks. Here are the six rooflines and layouts Mountain State Construction builds, and how to pick the one that fits your project.
Six rooflines.
Every roofline is a trade between drainage, headroom, light, cost, and look. There is no single best choice, only the right one for how your building gets used and where it sits. Explore each below, then bring your project into a quote and we'll recommend the fit.
Single-Slope
One sloped plane. The simplest, most economical line, with drainage aimed where you want it.
ExploreGable
The classic symmetric peak. Balanced drainage and full headroom down the center.
ExploreMonitor
A raised center with lower side bays. Built-in clerestory light and natural ventilation.
ExploreGambrel
The two-pitch barn roof. Opens up real usable space under the roofline.
ExploreRoof-Only
An open structure on columns, no walls. Cover and airflow without enclosure.
ExploreMulti-Building
Two or more structures joined and planned together. Distinct zones, phased growth.
ExploreStart with how it's used.
Where does the water go?
If you need to send snow and runoff to one controlled side, a single-slope does it. If even shedding is fine, a gable works anywhere.
How much height do you need?
Lofts, lifts, and tall equipment want the ridge height of a gable, or the upstairs room of a gambrel.
Do light and air matter?
For barns, arenas, and shops where ventilation and daylight count, a monitor roof builds both into the structure.
Walls, or just cover?
If you only need to keep equipment out of the weather, a roof-only structure skips the walls and the cost that comes with them.
Roof style FAQ.
Which roof style is best?
There isn't one. The best roofline depends on your drainage, headroom, ventilation, look, and budget. Gable is the versatile default; the others each win in specific situations.
What's the difference between a gable and a monitor roof?
A gable is a single symmetric peak. A monitor adds a raised center section above two lower side bays, which creates room for clerestory windows and natural ventilation.
Which roof style is most economical?
A single-slope roof typically uses the fewest framing parts, which tends to make it the most economical for a given footprint.
Can the roof style change my building's interior?
Yes. Roofline drives ridge height, loft potential, light, and ventilation, so it's worth choosing early, alongside your building type and size.
