Choose the Roof That Works Best for Your Climate, Budget & Style
Not all roofs are created equal — and the one you choose affects durability, appearance, water drainage, and long-term performance. At Great Carports, we help you select the best roof system for your needs, not just the cheapest.
Metal Building Roof Styles (Good → Better → Best)
Regular Roof (Good)
- Rounded corners & horizontal panels
- Most affordable option
- Best for mild climates and budget builds
- Popular for small carports & temporary shelters
A-Frame Horizontal Roof (Better)
- Clean lines, matches most residential homes
- Horizontal panels, boxed eaves
- Great value for most uses
- Ideal for garages, workshops, combo units
Vertical Roof (Best)
- Vertical panels shed rain, snow & debris fast
- Strongest structural support
- Required on most certified buildings
- Best for large structures, long-term durability, and heavy weather
Material Options: Strength That Lasts
- Framing: 14-gauge standard (upgrade to 12-gauge for extra strength)
- Roof Panels: 29-gauge standard with optional 26-gauge
- Bracing: Reinforced trusses, peak and leg braces where needed
- Span: Structures up to 40’ wide and longer than 100’ available

FAQs – Roof Types for Metal Buildings
What’s the difference between horizontal and vertical roof panels?
Horizontal panels run front to back and are more budget-friendly. Vertical panels run top to bottom and allow better drainage — perfect for snow, rain, and leaves.
Do I need a vertical roof for my area?
If you’re in a region with heavy rain, snow, or wind — yes. Vertical roofs are stronger and better at handling tough weather.
Can I upgrade the roof framing or steel gauge?
Absolutely. We offer 12-gauge upgrades and reinforced trusses for greater load-bearing and durability.
Can I mix roof styles on the same structure?
Yes — for example, you can have a vertical roof on the main structure and regular roofs on lean-tos.

FAQs – Insulation & HVAC in Metal Buildings
Do I really need insulation?
If you’re using your building for anything more than basic storage, yes. Insulation protects your investment and makes the space more comfortable.
Can I install insulation or HVAC later?
You can — but it’s cheaper and easier to do during initial construction. We can also retrofit if needed.
What’s the best insulation for garages or workshops?
Spray foam is the most effective, but radiant barriers or bubble wrap can work for lighter-duty use.
Will you install the HVAC system too?
Yes. We handle everything — from ductwork and mini-splits to fans, vents, and full HVAC installs.
Can I finance insulation and HVAC?
Absolutely. We offer financing and rent-to-own plans that can include the full insulation and HVAC package.
