Metal or shingles: how do you choose a roof in Florida?

You choose an assembly that fits this house, not a winner for every house. Architectural shingles and standing-seam metal differ in underlayment, fasteners, flashing, attic heat, and upkeep. Pitch, the deck, and the wind design for the parcel decide whether either one belongs. A color does not. Marion County is not the High-Velocity Hurricane Zone, so a coastal sheet does not settle an Ocala lot.

The covering is the last layer

On a replacement, both systems start as a tear-off. Soft wood will not hold a nail or a clip. Underlayment is the water plane, and flashing moves water the field does not. Naming only the shingle or the panel has not named the roof. That tear-off is the roof replacement scope. What changes the scope is the roof replacement cost page.

Exposed-fastener panels, screws through the flat of the sheet, are not standing seam and are not in this comparison. Three-tab shingles are not architectural shingles. A nearly flat roof is neither conversation. Tile is a third system. The wider menu, still without a crowned product, is which materials suit a Florida house.

Underlayment is not the same job under both

Under shingles, the sheet backs up the laps. Wind-driven rain that gets past a seal, a valley, or a pipe has to ride on it. The code edition on the permit, and the shingle approval, say where a self-adhered sheet is required. A short or wrinkled lap becomes the leak the new shingles are blamed for.

Under standing seam, the panels shed rain on the field. Water blown uphill at an eave, a ridge, or a wall still lands on the underlayment. The panel runs hotter than a shingle, so the sheet has to take that heat and the movement of the metal. Metal is not a reason to skip the sheet. Field details are on the standing-seam page and the shingle assembly page.

Clips and nails are different ways of holding the roof down

Architectural shingles are nailed in the zone printed on the shingle, flush, at the count the approval and the wind design require. Nails above that zone are barely covered, and the tab lifts in the wind. You will not see those nails from the driveway until it does. The count is not a Miami-Dade pattern pasted onto an inland ranch.

Standing seam is held by clips under the seam. Fasteners go through the clips into the deck, not the pan. Some clips let a long panel move in the sun. A south slope here gets hot enough that a panel pinned everywhere buckles. Clips in soft decking pull out. Oil-canning, a waviness in a wide pan, is an appearance issue, not a leak by itself.

Flashing does not swap between the two systems

On a shingle roof, step flashing is one piece per course, lapped with the shingle, then counterflashed at stucco or block. A headwall, a chimney, and a skylight each have their own pattern. Sealant on the stucco face is not counterflashing. It fails in the heat. Pipe boots are part of that roof, and the rubber sits in full sun.

On standing seam, the closures, the eave, and the wall flashing belong to that panel system. Shingle step flashing under a panel end is not a metal detail. Sealant is not a closure. Both systems replace tired wall metal. On stucco-over-block houses around Ocala, the old flashing is often buried, so the new work cuts a joint and counterflashes it.

Attic heat sits under either covering

A closed attic cooks a new roof, shingle or metal. Soffit intake and an exhaust path both matter. Insulation in the eaves blocks the intake. A ridge vent with no intake pulls from bath fans, and a fan that ends in the attic wets the deck. Metal does not ventilate the attic. A lighter color is a selection, not an energy number. The hotter metal skin is why its underlayment is not the shingle sheet.

Rain noise is a consideration, not a scare

Rain on standing seam over a solid deck and underlayment is not an open barn, and it is not silent. Owners under a low ceiling should hear that before panels are ordered. They should not be told the house will roar, and they should not be promised silence. Shingles are not a soundproof lid either. Noise is a comfort question, not a scare.

Maintenance follows the covering and the trees

Neither roof is maintenance-free. Oaks drop leaves into valleys and gutters, and wet leaves push water sideways. A limb will tear a shingle and crease a panel. Dark streaks on shingles are usually algae. Pressure washing strips granules. Rubber boots often crack while the field still looks fine. On metal, a crease is a repair or a new panel.

What a site visit compares before a covering is named

Where it is safe, someone walks the slopes and enters the attic. Pitch is checked on each plane, because one low wing can rule a product out. The deck is judged where it gives. Walls, chimneys, and pipes are listed because flashing is part of the choice. Soffits, oaks, and any addition tied into an older slope are noted. What cannot be seen is not sold from the curb.

• Pitch of every plane, including the low ones
• Deck condition and how many coverings are already down
• Walls, chimneys, and penetrations that must be reflashed
• Soffit intake, exhaust, and any fan ending in the attic
• Oaks, limbs, and valleys that will hold leaves
• Whether the geometry can take panels and clips, or shingle courses

What Marion County weather changes

The ordinary week is a sideways afternoon storm, then sun. Humidity feeds algae and condensation under metal. Wind design comes from the code for the site: height, exposure, and roof shape. Miami-Dade and Broward are the High-Velocity Hurricane Zone. Marion County is not. Skipping fasteners inland is the opposite mistake. Older Ocala houses often have blocked soffits and flashing buried in stucco.

Mistakes that turn a comparison into a bad roof

The usual miss is treating metal as a fancy shingle, or shingles as cheap metal. Another is choosing from a photo of a different pitch, or covering the old shingles so the deck is never seen.

• Naming a color before the deck and the flashing
• Calling exposed-fastener panels standing seam
• Using a shingle sheet under metal because it is familiar
• Copying a coastal nail or clip schedule, or ignoring wind inland
• Expecting either roof to fix a closed attic
• Declaring a winner for every house on the street

Decisions to make before anyone names a winner

• Does the slope meet the product you are actually buying
• Will the deck hold nails or clips after tear-off
• Which underlayment belongs under that covering
• Can the walls be counterflashed, not caulked
• Is the attic able to move air
• Who will clear valleys and gutters under the oaks

Ocala Building Contractor holds Florida certified building contractor license CBC1263067. That is not a roofing-only license. When this company takes the work, the roofing trade is subcontracted to a contractor licensed for that trade. The scope still names the assembly. If neither covering fits the roof in front of you, that is the answer.

Roof covering, underlayment, and wind design follow the Florida Building Code edition on the permit, published through the Florida Building Commission at https://floridabuilding.org. Statewide product approval for roofing used as approved is Florida Statutes section 553.842, https://www.flsenate.gov/Laws/Statutes/2025/553.842.
