Metal Roof or Shingles? An Honest Comparison for a North Florida House
We install both. Most of what we do is metal, because that is what people in Putnam County and the counties around it keep asking for, but we put on plenty of shingle roofs too. Here is the comparison the way Juan gives it standing in a driveway, without the sales pitch.
Upfront Cost: Metal Costs More, and Here Is Why
A metal roof costs more up front than an architectural shingle roof on the same house. The gap changes with the panel, the gauge, the finish and the shape of the roof. The reason for the gap is mostly labor and material grade. Panels are cut to length for each run, fitted around every vent and valley, and on a standing seam roof clipped or nail-stripped one at a time. A simple gable on a block ranch in Palatka narrows the difference. A cut-up roof with hips, dormers and a dozen penetrations widens it.
Shingles go on faster, the material costs less, and a shingle roof is a very good roof when the deck is sound and the nailing is right. If the budget is tight and the plan is to sell in a few years, the money argument usually lands on shingles. Financing through Regions Bank closes some of the gap for people who want metal and would rather spread it out.
Lifespan in Florida Sun
This is where the two roofs pull apart. Florida UV is relentless, and the attic runs hot from May to October. Asphalt shingles age faster here than they do up north. The granules wear off the south and west slopes first, the mat dries out, and the edges start to curl. A good architectural shingle, ventilated properly, gives a solid run of years in this climate. A cheap three-tab gives less, and we see plenty of shingle roofs in Putnam County that are done well before their owners expected.
A metal roof from a Florida manufacturer, in a factory finish, lasts decades longer. Roughly twice the life of a shingle roof is a fair way to think about it, and a standing seam panel in a PVDF finish sits at the long end of that. The panels we install come from Tri County Metals, and their finishes (Core Defender on exposed fastener panels, Max Defender PVDF on standing seam, Coastal Defender on aluminum within 1500 feet of salt water) are backed by Tri County Metals' limited paint and finish warranty, registered with the manufacturer. That is their warranty on the finish, not a promise from us about the roof.
Wind: What the Approvals Actually Say
Both roofs have to carry a Florida Product Approval to go on a house here, and both can be installed to hold through a tropical storm. The difference is in how they fail. Shingles rely on a sealant strip that bonds each course to the one below it in warm weather. When the nails are high or the strip never sealed, wind gets under the tab and peels it. Six nails per shingle, sealed, on a re-nailed deck with peel-and-stick underlayment is how a shingle roof holds, and it is how we install one.
A metal panel has no tabs to lift. Every panel we install carries a Florida Product Approval in the FL 36904 family, and most also hold a Miami-Dade Notice of Acceptance, the strictest wind approval in the state. Our part of Florida is not in the high velocity hurricane zone, which is Miami-Dade and Broward, so those rules do not apply to a roof in Crescent City or DeLand. The point is that the panel has been tested to a standard well beyond what our counties require. Fastening still matters: screw and clip spacing are set by the approval, not by whoever is on the roof that day.
Insurance: Ask Your Agent Before You Decide
Many insurers in Florida look favorably on a metal roof, and many have grown wary of older shingle roofs, to the point of declining or not renewing policies when a shingle roof gets past a certain age. What we cannot tell you is what your carrier will do, so ask your agent before you sign an estimate, and ask two things: how the carrier treats a new metal roof versus a new shingle roof on your premium, and what it wants from a wind mitigation inspection (the OIR-B1-1802 form) after the work.
One more thing to ask about is cosmetic damage. Hail dents a metal panel, and some policies exclude dents that do not cause a leak. That is a fine print item worth reading before you choose. If a storm has already hit your roof, our storm damage page explains how we document the damage and meet the adjuster.
Noise and Heat: Two Myths and One Truth
The noise myth comes from pole barns. A panel screwed to open purlins with nothing under it is loud in rain. On a house, the panel sits over a solid deck, underlayment and an insulated attic, and the sound in the bedroom is close to what you hear under shingles.
The heat myth runs both ways. Some people think metal makes the house hotter. It does not; a light or cool-pigment panel reflects far more sun than a dark shingle, which is the subject of our post on the most energy efficient metal roof color. Others think metal alone will cut the power bill in half. The truth is that the attic decides most of it. Ventilation and insulation matter more than the material, and we look at both on every inspection.
Resale, Looks and Maintenance
A new roof of either kind helps a sale, because a buyer's inspector and a buyer's insurer both ask about roof age first. A metal roof with most of its life ahead of it is an easier conversation than a shingle roof at mid-life. On looks, some houses want one or the other. A tin-roof farmhouse in the lake country, a river house in Welaka, a barn or a block ranch all wear metal well. A brick house with a busy roofline in a Jacksonville subdivision often carries a dark architectural shingle better.
Maintenance is lighter on metal. Algae streaks, the black lines on so many north-facing shingle slopes, do not take hold on a painted panel the same way. Pine needles and oak leaves slide off a steeper metal roof instead of holding water. Exposed fastener panels do need their screws checked over the years, because the washers age and the screws work with thermal movement; standing seam has no exposed screws to check.
When Shingles Are the Right Call
Plenty of times. When the house will be sold within a few years and the money is better spent elsewhere. When the roofline is so cut up that fitting panels would cost far more than the house justifies. When an HOA in a newer subdivision only allows shingle. When a sound shingle roof beats a metal roof you cannot afford yet. And on a low-slope section, where neither one belongs and TPO single ply is the real answer.

Frequently Asked Questions
For a homeowner planning to stay long enough to otherwise need a second shingle roof, usually yes. Metal lasts decades longer in this sun, sheds debris and algae better, and often helps the insurance conversation. For a homeowner expecting to sell within a few years, a well installed architectural shingle roof is often the better use of the money.
Many Florida insurers treat a new metal roof favorably, and many are wary of older shingle roofs, but carriers differ and we are not your agent. Ask yours how a new metal roof versus a new shingle roof affects your premium, and whether a wind mitigation inspection after the work would help. We can supply the roof details the form asks for.
Sometimes. A re-cover, with panels over furring strips on top of one layer of shingles, is allowed by the Florida Product Approval for some panels where the deck is sound and the code permits it. It saves the tear-off. It also hides the deck, so we only do it after checking the attic and the decking from below. A full tear-off is the safer default.
