Snap-lock vs mechanically seamed panels
Every standing seam metal roof panel has two raised legs that join the panels on either side. How those legs close is the first real choice on a quote.
Snap-lock panels press together without a seaming machine. Englert's A1100, for example, uses concealed clips and needs no mechanical seaming or seam cap. Gulf Coast Supply, a Florida maker, calls its 1-inch snap-lock panel one of its best-selling panels and a fit for many homes.
Mechanically seamed panels are folded shut on the roof with a hand or electric seamer, which This Old House notes adds time and labor. Tri County Metals' Florida approval lists 1.5- and 2-inch panels closed with a 180° double lock.
Slope can decide it for you. Englert requires its mechanically seamed A1300 panel on roofs flatter than 3 inches of rise per foot. On a low porch or a long, shallow run, ask whether the panel quoted is approved for that pitch.

Clips, nail strips and thermal movement
Standing seam panels are held down from underneath, not through the face. Clip-fastened panels use small metal clips screwed to the deck and locked into the seam. Nail-strip panels have a slotted flange along one edge that is fastened down, then covered by the next panel.
Both methods exist to let the metal move. Classic Metal Roofing Systems says its clips let panels expand and contract without rippling or buckling. Tri County's approval lists one-piece expansion clips in 1.5- and 2-inch sizes.
Roof Bear's Orlando metal page spells out its clip spacing, which we like to see. Ask any roofer how far apart the clips go on your roof, because the spacing should match the tested assembly in the product approval.
Panel widths and seam heights
Residential panels run from 12 inches wide to a little under 19, with seams from 1 to 2 inches tall. Narrower panels put more seams on the roof. Here is what Tri County Metals of Trenton, Florida, lists in its 2023 Florida Building Code approval.
| Panel | Seam | Max coverage | Minimum metal |
|---|---|---|---|
| TCM-LOK 1 in. | 1 in. snap-lock with nail strip | 16 in. | 26 ga steel or .032 in. aluminum |
| TCM-LOK 1.5 in. | 1.5 in. snap-lock with nail strip | 15 in. | 24 ga steel |
| 1.5 SL-LOK | 1.5 in. snap-lock | 15.5 in. | 24 ga steel |
| 1.75 SS-LOK | 1.75 in. snap-lock | 18 in. | 24 ga steel |
| 1.5 MS-LOK | 1.5 in. double-lock mechanical | 16 in. | 24 ga steel |
| 2 MS-LOK | 2 in. double-lock mechanical | 18.75 in. | 24 ga steel |
Other makers land in the same range. Classic's aluminum ClickLock comes in 12-inch panels with 1¾-inch seams, and Englert's S2000 uses a 1¾-inch snap-lock seam.
24 vs 26 gauge
Gauge runs backward: the lower the number, the thicker the steel, so 24 gauge is heavier than 26. HomeGuide says most residential metal roofing is 24 or 26 gauge.
For standing seam in Florida, we'd treat 24 as the default. In Tri County's state approval, every panel except the 1-inch nail-strip profile requires at least 24 gauge. Gravity Roofing gives a 10-year workmanship warranty on its 24-gauge standing seam tier.
Orlando roofers differ here. T Mark lists 24-gauge Kynar snap-lock, while Mid Florida Exteriors and Fiddler's Roofing offer both 24 and 26 gauge. If two quotes differ by gauge, you're not comparing the same roof.
Galvalume steel vs aluminum
Most standing seam is steel coated with Galvalume, which Englert describes as 55% aluminum, 43.5% zinc and 1.5% silicon. Florida's code sets AZ50 Galvalume or G-90 galvanized as the minimum coating for steel roofing.
HomeGuide calls Galvalume one of the most popular materials away from the coast. Aluminum costs more but won't rust, and Englert says it may be preferred where salt exposure is heavy. MBCI adds that aluminum near salt spray should get stainless steel screws.
Orlando is inland, so a beach house makes a stronger case for aluminum than a Winter Park ranch. On our list, Roof Bear and Mid Florida Exteriors both offer aluminum alongside steel.
PVDF (Kynar) paint finishes
Paint is the part of the roof you look at for decades. PVDF resin paints are sold under names like Kynar 500 and Hylar 5000. Classic coats ClickLock with Sherwin-Williams Fluropon, a 70% PVDF paint it says resists chalking and fading.
Finish warranties are separate from the panel itself. Classic's ClickLock finish coverage names peeling, chalking, cracking and fading. Tri County Metals, Thomas Roofing's panel supplier, carries 25- to 40-year finish warranties.
Ask for the finish warranty by name and in writing. A quote that just says "painted steel" leaves out the part that fades.
Standing seam cost in Orlando
JA Edwards, an Orlando roofer, publishes $18,000 to $35,000 for a standing seam metal roof on a typical home. Direct Metal Roofing, a Cocoa company that serves Orlando, prices standing seam next to 5V so you can see the gap.
This Old House's national range runs wider because it includes copper. Its guide, updated March 31, 2026, puts standing seam at $8 to $39 per square foot, or $7,540 to $39,430 for a 1,000-square-foot roof. HomeGuide, dated November 21, 2025, gives $9 to $16 per square foot.
This Old House names metal type, panel width, gauge and roof design as the main price drivers, so line those up when you compare quotes. More local numbers are on our metal roof cost in Orlando page.
Florida code and wind rules
A standing seam metal roof in Florida may go on a pitch as flat as 1/4 inch of rise per foot. The panels must pass wind uplift testing such as UL 580, ASTM E1592 or TAS 125.
Panels must also be made to a state product approval under a third-party quality program. Classic's ClickLock, for example, carries Florida Product Approval FL 10687-R5. Ask for the number on your quote and check that the install matches it.
The strictest rules apply in the High-Velocity Hurricane Zone, which the code limits to Miami-Dade and Broward counties. Orlando roofs use statewide approvals instead, such as Tri County's non-HVHZ report.
Replacing only part of a roof? Florida Statute 553.844(5) covers that. When 25% or more of a roof built under the 2007 code or later is replaced, only that part must meet the current code.
