Interlocking metal roof vs standing seam at a glance
Interlocking here means four-way interlocking metal shingle systems. Around Orlando that is Metlok, Galvalume steel and one of our sponsors, and Interlock, an aluminum brand sold through independent installers.
| Factor | Interlocking | Standing seam |
|---|---|---|
| What it is | Shingle-size panels locked to their neighbors on all four sides | Long panels from ridge to eave, joined at raised seams |
| Fasteners | Hidden under the next course | Hidden clips under the seams |
| Look from the street | Slate or shingle (Metlok); slate, cedar, shake or tile (Interlock) | Clean vertical lines that read as metal |
| Lowest slope in Florida's code | 3 inches of rise per foot | 1/4 inch per foot |
| Solar mounting (per Interlock) | Brackets with flashing | Clamps to the seams, no holes |
| Orlando price (JA Edwards) | $12,000–$22,000 for metal shingle or stone-coated | $18,000–$35,000 |
| Installed per sq ft (HomeGuide, Nov 2025) | $6–$14 for metal shingles | $9–$16 |
| Installers around Orlando | Metlok's own crews; Interlock's certified independent installers | Most metal roofers on our list |
Both systems hide their fasteners, so neither leaves rows of screws to check. The real differences are look, slope, solar, price and who can install them.
Look and which houses each suits
Interlock sells both systems in aluminum and says the choice is mostly about looks. It pairs standing seam with modern and farmhouse homes, and its shingle, shake and tile profiles with craftsman, colonial and Mediterranean styles.
Metlok offers Shingle and Slate profiles now, with Shake and Barrel listed as coming soon. Its colors include Black Summit, Carbon Gray, Coastal Drift and Weathered Ridge.
Our take: on a street of stucco ranch homes, standing seam looks like a deliberate design statement, and some owners want exactly that. If you'd rather the roof blend in, a slate or shingle profile is the quieter pick. If an HOA must approve the roof, Metlok's offer terms schedule installation after that approval.
Wind ratings and Florida code
Florida's residential code ties metal shingles to their product approval. The approval must state the allowable uplift resistance, and the roof's design uplift pressure can't exceed it.
Interlock publishes its numbers. Approval FL7263-R7 lists maximum design pressures of -187.5 psf for its shingle and slate profiles and -110.5 psf for shake. Those are allowable values with a 2-to-1 safety factor, tested to UL 580, UL 1897 and TAS 125.
Metlok says its patented four-way interlock was engineered for Florida's wind, rain and impact conditions. It says locking every panel on all four sides removes uplift weak points common in standing seam. The Metlok pages we read don't list a Florida approval number, so ask for it.
Standing seam panels need their own Florida approval too. Gravity Roofing, which installs standing seam, says no single wind rating applies to every metal roof. The panel, gauge, deck and fastening pattern all change it.
After Hurricane Ian, IBHS found damage on about 12% of the metal roofs it surveyed, mostly from nearby structures failing. That figure covers metal roofs in general, not one system.
Low-slope roofs and solar panels
This is where standing seam wins outright. Florida's residential code bars metal roof shingles from slopes below 3 inches of rise per foot. Standing seam can go as low as 1/4 inch per foot.
So a nearly flat porch, lanai or addition may need standing seam even if the main roof is interlocking. Ask the roofer to measure every slope before you choose.
Solar is the other edge. Interlock says standing seam is ideal because solar panels clamp to the seams with no roof penetrations. Its shingle profiles take solar too, using brackets with flashing.
Heat and rain noise
Orlando International Airport averages a 92°F high in July (NOAA 1991–2020 normals). The EPA says a cool roof can cut peak cooling demand 11% to 27% in air-conditioned homes.
The finish matters more than the system. The EPA lists metal shingles or tiles with reflective paint as cool-roof options and calls solar reflectance the most important property. Ask for that number on the exact color you pick.
For noise, Florida's code requires metal shingles to go on a solid or closely fitted deck. Metal panels can go on solid or spaced sheathing. McElroy Metal cites a Luleå University study: rain on metal measured about 52 dBA over a full roof assembly and 61 dBA over open framing.
McElroy says attic insulation has the biggest effect on how much rain you hear indoors. Over a solid deck and an insulated attic, either system can be quiet; our guide to metal roof rain noise has the details.
Lifespan and warranties
HomeGuide gives metal roofs 30 to 80+ years. In humid climates, it says corrugated metal typically lasts 30 to 50 years and standing seam longer.
Metlok's warranty page describes a 50-year limited lifetime warranty covering labor and materials, transferable subject to its transfer requirements. Because Metlok makes and installs the roof, one company holds both halves.
Interlock's Guardian Limited Lifetime warranty covers the original owner and can transfer once, for a $300 fee. In Florida your installer, not Interlock, backs the workmanship, so get that in writing.
Standing seam usually comes with a paint or panel warranty plus the installer's workmanship warranty. Gravity Roofing gives 10 years of workmanship on its 24-gauge standing seam. Mid Florida Exteriors advertises lifetime service and labor, a 40-year paint warranty and 25 years on corrosion.
Cost in Orlando
JA Edwards, an Orlando roofer, publishes $12,000 to $22,000 for a metal shingle or stone-coated roof and $18,000 to $35,000 for standing seam. HomeGuide's national guide, dated November 21, 2025, points the same way.
HomeGuide puts metal shingles at $6 to $14 per square foot installed and standing seam at $9 to $16. Interlock says premium interlocking aluminum sits at the top of the shingle range, and that standing seam typically costs a bit more.
By Interlock's account, the price gap in interlocking metal roof vs standing seam is smaller than the gap in looks. Metlok quotes at a free in-home visit and doesn't publish prices; its November offer takes $3,500 off a roof signed by November 30, 2026. See our Orlando metal roof cost guide for more ranges.
Repairs after a storm
Interlock says a trained installer can release one damaged interlocking shingle and swap in a new one without disturbing the roof around it. That keeps a fallen-branch repair small.
Standing seam panels run from ridge to eave, so ask a standing seam roofer how they would replace one damaged panel. Ask how long a matching panel takes to arrive, too.
Color can be the catch with either one. HomeGuide lists color matching for repairs as a metal roof drawback. Interlock adds that interlocking shingles are less forgiving of poor installation, and that many general roofers have never laid them.
Who installs each around Orlando
Metlok, one of our sponsors, makes its panels in its own Florida factory and installs them with its own crews; it says it never subcontracts. Its Google profile showed 4.2 stars from 6 reviews on November 8, 2026.

Interlock doesn't install in Florida itself. Interlock Roofing of America refers homeowners to certified independent installers through its Metal Roofing Florida site. Ask each installer for its license, insurance and workmanship warranty.
Standing seam has far more installers. Four on our list:
- Universal Roof & Contracting (sponsor): installs standing seam, stone-coated steel and metal pressed into tile and shingle profiles.
- Mid Florida Exteriors: 24- and 26-gauge standing seam, with the warranty terms above.
- Gold Key Roofing: says it installs standing seam on homes "because it lasts," with workmanship and manufacturer warranties in writing.
- Gravity Roofing: 24-gauge standing seam with a 10-year workmanship warranty.
Panel types, seams and gauges are covered in our standing seam guide for Orlando.
Which fits an Orlando house
On interlocking metal roof vs standing seam, pick interlocking for a slate or shingle look that blends in, on roofs pitched 3-in-12 or steeper. Pick Metlok if one company answering for product and labor matters most. Our interlocking metal roofing page covers both brands.
Pick standing seam for a modern or farmhouse look, low-slope sections, clamp-on solar, or several bids from different roofers. For the sponsor-specific version of this comparison, see Metlok vs standing seam.
On a house with a low porch, the practical answer can be both: interlocking on the main roof, standing seam on the porch. Compare installers on our list of Orlando metal roofers.
