What interlocking metal roofing is
An interlocking metal roof is made of shingle-sized panels that hook into the panels above, below and beside them. Each panel locks to its neighbors on all four sides, and the fasteners sit under the next course, so none are exposed to sun or rain.
That is different from a metal shingle that simply overlaps the course below and is nailed through. With an overlap, the nail and gravity hold the bottom edge. With a four-sided lock, there is no loose edge for wind to catch.
It is also different from standing seam, where long vertical panels join at raised seams, and from exposed-fastener panels like 5V crimp, where screws go through the face of the panel.

- 26-ga Galvalume steel shingles
- Profiles
- Shingle, Slate; Shake and Barrel coming

Metlok makes its own steel shingles in its own factory, and its own crews install them, so one company answers for both. Each panel locks to its neighbors on all four sides, so no screws show on the finished roof. Its Shingle and Slate panels carry Florida Product Approval FL47482.
Shingle and Slate profiles are available now, with Shake and Barrel listed as coming soon, in colors such as Carbon Gray, Coastal Drift and Tuscan Clay. November offer: $3,500 off a new Metlok roof signed by Nov 30.
Watch for: Only 6 Google reviews so far, and it's one product line. For standing seam, see the next pick.

Interlock (aluminum)
Interlock is an aluminum shingle system made in Delta, British Columbia. The maker says it does not install in Florida itself. Interlock Roofing of America works with certified independent installers here, through its Florida site, Metal Roofing Florida.
Its interlocking metal roofing carries Florida Product Approval FL7263-R7, which covers the state outside the High-Velocity Hurricane Zone. Orange, Seminole, Osceola and Lake counties are outside that zone, so the approval applies here. Ask the installer you're referred to for its own license, insurance and workmanship warranty, as Interlock itself advises.
Interlock is not on our list of Orlando roofers because it sells through independent installers, not one local company with its own Google reviews. Metlok makes and installs its own roofs, so one company answers for both.
Interlocking metal roofing vs other metal roofs
| System | How panels attach | Fasteners | Material |
|---|---|---|---|
| Metlok | Four-way interlock: each panel locks to the next on all four sides | Hidden | 26-gauge Galvalume steel |
| Interlock | Four-sided interlock | Hidden | Aluminum |
| Standing seam | Long panels joined at raised seams, held by clips | Hidden under the seam | Steel or aluminum |
| Stone-coated steel | Ask the installer: the makers we checked don't describe a four-way lock | Varies by product | Steel with stone granules |
| 5V crimp and rib panels | Overlapping panels screwed to the deck | Exposed | Steel or aluminum |
If you like the look of shingle, slate, shake or tile, the interlocking systems and stone-coated steel are the metal options that read as a traditional roof from the street. Our guide to metal shingles in Orlando covers the looks in more detail.
Wind ratings for interlocking metal roofs in Florida
Every roof in Florida needs a product approval for wind. For interlocking metal roofing, the approval tells you how much uplift the system was tested to hold.
- Interlock, FL7263-R7: maximum design pressures of -187.5 psf for its shingle and slate profiles and -110.5 psf for shake, according to the maker. Those are allowable values with the code's 2-to-1 safety factor already applied. Testing followed UL 580, UL 1897 and TAS 125.
- Metlok, FL47482: Florida Product Approval for its Shingle and Slate panels (min. 26-gauge AZ50 Galvalume steel), approved June 2025 for use outside the High-Velocity Hurricane Zone, which includes Orange County. Metlok says its four-way interlock was engineered for Florida's wind, rain and impact conditions.
Ask any installer for the product approval number and check it yourself in the Florida Building Commission's product approval search. Then check that the approval covers your county and your roof's design wind pressure.
What interlocking metal roofing costs in Orlando
Neither interlocking system publishes a price list, because the price depends on your roof's size, pitch and how much decking needs work. For a sense of the range, Orlando roofer JA Edwards publishes $12,000 to $22,000 for metal shingle or stone-coated steel roofs and $18,000 to $35,000 for standing seam.
Metlok's November offer is $3,500 off a new Metlok roof signed by November 30. See our full metal roof cost guide for Orlando for prices by system.
Warranties on interlocking metal roofs
Read who stands behind the labor, not just the panels. Metlok's warranty page describes a 50-year limited lifetime warranty covering both labor and materials, transferable to a new owner subject to its transfer rules. Because Metlok makes the panels and its own crews install them, one company holds both halves.
When the maker and the installer are different companies, as with Interlock in Florida, the material warranty comes from the maker and the workmanship warranty comes from the installer. Get both in writing.
