Wide coverage, smart drainage, easy build

Full two-car span
The wide M-shape frame shelters two vehicles side by side under one roof, so you are not paying for or parking under two separate single covers.

Twin-peak drainage
The two sloped sections meet at a central valley, channeling rain and melting snow off the roof instead of letting it pool over a wide flat span.

Rust-free aluminum
Structural aluminum will not rust like steel, and its lighter weight makes the wider double-bay components manageable to lift and bolt together at home.
M-shape vs. other double-carport roofs
| Feature | M-Shape DoubleTHIS COLLECTION | Flat / Single-Slope |
|---|---|---|
| Two-car coverage | ✓Full side-by-side span in one structure | Works, but a single slope can feel long across a wide bay |
| Roof drainage | ✓Twin slopes drain to a central valley and outer edges | Drains to one side; pitch matters more on wide spans |
| Profile / look | ✓Balanced symmetrical M over a two-car footprint | Lower, simpler line; leans toward one edge |
| Material | ✓Rust-free structural aluminum | Varies by kit; aluminum or steel |
| DIY assembly | ✓Ships flat; lighter aluminum parts | Depends on material and span |

M-shape double carport FAQs
How wide is an M-shape double carport, and will it fit two cars?
M-shape double carport kits are sized to shelter two standard vehicles side by side, with the twin-peak roof spanning the full width of the parking area. Exact width, length, and post spacing vary by model, so check the specifications on each product page in this collection to match the footprint to your driveway before you order.
What makes the M-shape roof different from a flat or single-slope carport?
The M-shape roof uses two sloped sections that meet in a central valley, forming the M profile. That twin-pitch shape sheds rain and melting snow toward the center and outer edges instead of pooling, and it gives the structure a balanced look over a wide two-car bay. A flat or single-slope roof drains in one direction and suits narrower or single-vehicle spans.
Are M-shape double carports made from aluminum, and do they rust?
Yes. These kits use structural aluminum, which does not rust the way steel does. Aluminum forms a natural oxide layer that protects it from rain, humidity, and coastal salt air. If you are weighing materials, our aluminum vs. steel carports comparison breaks down corrosion, weight, and upkeep side by side.
Do I need a permit to install an M-shape double carport?
Permit rules depend on your city and county, structure size, and whether it is freestanding or attached. Some areas require a permit for a two-car cover; others do not. Check with your local building department before installation, and see our permit guide for an overview of what departments typically ask for.
Can I assemble an M-shape double carport myself?
Most homeowners can. Because aluminum components are far lighter than steel, the kits are designed for DIY assembly with common tools, though a second pair of hands helps when positioning the wider roof panels. Each order ships with hardware and instructions, and our installation guides walk through the process step by step.
