Metal is the longest lasting roof most Dallas homeowners will seriously consider, and it comes with one honest caveat that matters more here than almost anywhere else in the country. It dents in hail. Everything on this page is written around that trade-off rather than around it.
Thinking about metal? We will measure, quote it against a comparable asphalt option and tell you honestly which one suits your house and how long you plan to stay.
Every honest conversation about metal roofing in North Texas starts here, because we are in the highest hail loss corridor in the United States and it is the single thing most likely to disappoint you later if nobody mentions it now.
Metal dents. It very rarely leaks. Those are two different statements and the distinction is the whole argument.
When a large stone hits an asphalt shingle, it fractures the fiberglass mat and knocks off the granules, which is functional damage: the shingle has lost its ability to keep water out over time. When the same stone hits a metal panel, it usually leaves a dent. The panel is still watertight. The roof still works. It just does not look the way it did.
So the question is not whether metal survives hail, because structurally it usually does. The question is how much you care about the appearance afterwards, and how your insurance treats it.
This is the part that catches people, and it is worth reading your policy for before you spend the money.
Many Texas carriers apply a cosmetic damage exclusion to metal roofs. It means that if hail dents your panels but does not compromise their ability to shed water, the insurer treats the damage as cosmetic and does not pay to replace them. Some carriers apply it automatically to metal, some offer it as a premium reducing endorsement you can decline, and some do not apply it at all.
The practical consequence: a homeowner can install an expensive metal roof, take a serious hail hit, and find the roof is dimpled across every south facing plane with no coverage to do anything about it. That is not an insurance failure, it is what the policy said. But it is a genuinely unpleasant surprise.
Before you commit to metal in DFW, call your agent and ask one specific question: does my policy contain a cosmetic damage exclusion for a metal roof, and if so can I decline it and what does that cost. The answer should influence your decision. If your carrier will not cover cosmetic hail damage on metal, you are accepting that risk yourself for the life of the roof.
Vertical panels joined by raised seams, with the fasteners concealed underneath. This is the premium residential system and the one most people picture. The concealed fasteners are the key advantage: there are no exposed screws with rubber washers to degrade in Texas UV, and no penetrations through the flat of the panel where water can eventually find a way in. Panels are also designed to move as they expand and contract, which matters enormously in a climate that swings from 20 degrees to 110.
Panels screwed down through the face with rubber washered screws. Substantially cheaper, faster to install, and extremely common on agricultural buildings, workshops, barndominiums and outbuildings across North Texas. The trade-off is maintenance: those rubber washers degrade under UV and need inspection, and eventually the screws need backing out and replacing. Left alone for fifteen years, an exposed fastener roof leaks at the screws.
Pressed to resemble slate, tile or shake, and installed in courses rather than long panels. They suit homes where a standing seam would look wrong architecturally, and stone coated products handle hail appearance better than smooth panels. Worth a look on a traditional Dallas house where the owner wants metal longevity without the modern agricultural look.
The classic wavy profile, cheapest of all, and best suited to sheds, barns and covers rather than the main roof of a house.
| Metal | Notes | Best for |
|---|---|---|
| Galvalume steel | Aluminum and zinc coated steel, the workhorse of the market, strong and well priced | Most residential and commercial work in DFW |
| Galvanised steel | Zinc coated, older technology, less corrosion resistant than galvalume | Budget and agricultural |
| Aluminum | Will not rust at all, lighter, softer so dents more easily | Coastal, or where corrosion is the main concern |
| Copper and zinc | Very long life, develops a patina, expensive | Historic, architectural accents, bay roofs |
Finish matters as much as the metal. A quality coating in this market means a PVDF based paint system rather than a cheaper polyester. Texas UV is punishing, and the difference shows up as chalking and fading on a south facing plane within a few years on a poor finish, while a good one holds color for decades. Ask what paint system is specified, not just what color.
The intuition that a metal roof must be hotter is wrong, and the reason is worth understanding.
Metal has very low thermal mass. It heats quickly, and it sheds that heat almost immediately once the sun moves off it. Asphalt is the opposite: it absorbs heat all afternoon and radiates it into the attic for hours after sunset. On a Dallas evening the metal roof has already cooled while the asphalt roof is still pushing heat down through the ceiling.
Two things multiply that advantage:
Combined with correct attic ventilation, this is a genuine reduction in summer cooling load rather than a marketing claim.
Metal costs several times what an architectural asphalt roof costs, and it lasts two to three times as long. Whether that is a good deal depends almost entirely on one question: how long do you intend to own the house?
If you plan to be there for twenty five years or more, metal is frequently the cheaper option measured across the period, because you buy one roof instead of two or three. If you might move in six years, you will not recover the premium, and a Class 4 impact resistant asphalt roof is very likely the better financial decision in this market. Our roof replacement cost page explains what drives pricing on both.
Things that push a metal quote up:
We quote metal and a comparable asphalt option side by side, so you can see the real trade-off rather than being sold one of them.
Metal is less forgiving than shingles. A mediocre shingle install leaks eventually. A mediocre metal install can start causing problems in the first summer.
A long steel panel expands and contracts measurably across a Texas temperature range. Standing seam systems use clips that let panels slide. If panels are pinned at both ends, that movement has nowhere to go and it works fasteners loose, distorts panels and opens seams. This is the most common serious error we see.
The visible waviness in the flat of a panel. It is an inherent characteristic of light gauge metal rather than a defect, but it is made much worse by an uneven deck, over-tight fastening or handling damage. Heavier gauge, striations and a properly flat substrate all reduce it. A good contractor will raise it before you see it; a poor one will explain it afterwards.
Screws must suit the panel material. Putting the wrong fastener into the wrong metal sets up galvanic corrosion that eats the joint from the inside. The same applies to flashing and to any copper in contact with steel.
A high temperature synthetic underlayment is required beneath metal, because the assembly runs hotter than the equivalent under shingles and standard felt degrades. This is a line item that gets quietly downgraded on cheap quotes.
Eaves, rakes, ridges, valleys and every pipe and vent need purpose made flashing. Sealant used in place of proper flashing is a repair with a countdown on it.
It is sometimes possible to install metal over one existing layer of shingles, and in the right circumstances it saves the tear-off cost and keeps material out of landfill.
The conditions are strict, and they are worth insisting on:
Our general view is that on a roof with any doubt about the decking, tear-off is the right answer. The saving is real but it is not worth installing a fifty year roof over a deck nobody inspected.
The persistent myth is that metal roofs are loud in rain. That comes from barns and porch covers, where a panel spans open purlins with nothing behind it. On a house, with solid decking, underlayment, an attic space and insulation between the panel and you, a metal roof is not meaningfully louder than asphalt. Some owners find rain on it pleasant.
Metal does not attract lightning. If a house is struck, a metal roof is arguably safer, because it disperses the charge across a large conductive surface rather than concentrating it, and it is non combustible.
Metal is a slower job than shingles and the sequence is worth knowing, partly so you can tell whether the crew on your roof is doing it properly.
Standing seam panels are cut to length for each run, frequently roll formed on site from coil so there are no horizontal seams on a long slope. That means the measuring has to be right before anything is made, and it means a lead time. Custom flashing for valleys, ridges, walls and penetrations is fabricated to match. This stage is longer than homeowners expect and it is where errors become expensive.
Old roofing comes off, the deck is inspected and repaired, and flatness matters far more than it does under shingles. A dip that would disappear under asphalt will telegraph through a metal panel as visible waviness for the life of the roof.
High temperature synthetic across the field, with ice and water shield in valleys and around penetrations. Standard felt is not appropriate under metal because the assembly runs hotter.
Panels are set from one end and secured with clips that allow them to move as they expand and contract. Seams are then either snapped or mechanically seamed with a rolling machine, depending on the profile. Mechanical seaming gives the better weather performance on low slopes.
Eave, rake, ridge, valley, wall and penetration flashings are fitted. This is the slowest part of the job and the part that determines whether the roof leaks. On a complex roof it can take longer than laying the panels.
Expect notably longer than an asphalt replacement. A straightforward standing seam roof is typically several days rather than one or two, and a complex one longer still. Anyone promising a metal roof in a day is describing exposed fastener panels on a simple slope, which is a different product.
Where it makes less sense is a homeowner planning to sell within a decade, or one who would be genuinely upset by cosmetic dimpling after a hail storm and whose carrier excludes cosmetic damage. In those cases we will say so.

It will usually dent it rather than breach it, so the roof keeps working. The real risk is financial rather than structural: many Texas policies exclude cosmetic hail damage on metal, meaning dents are not covered. Ask your agent about that exclusion before you buy.
Not on a house. The myth comes from barns where panels span open purlins. With solid decking, underlayment and an attic beneath, it is not meaningfully louder than asphalt.
Considerably longer than asphalt, typically two to three times, with standing seam outlasting exposed fastener because there are no rubber washers to degrade. Actual life depends heavily on gauge, finish and installation quality.
No, generally cooler. Metal has low thermal mass so it sheds heat quickly instead of radiating it into the attic all evening the way asphalt does. Reflective finishes and a ventilated assembly increase that benefit.
Sometimes, if the decking is sound, the surface is flat, code allows the layer count and a proper separation layer is used. We would rather tear off than install a fifty year roof over a deck nobody has inspected.
Sometimes, particularly where the product carries a Class 4 impact rating and a Class A fire rating. It varies by carrier and it may come alongside a cosmetic damage exclusion, so ask about both in the same conversation.
The slight waviness visible in flat panel areas. It is inherent to light gauge metal rather than a defect, and it is reduced by heavier gauge, striated profiles and a flat substrate. Any contractor who does not mention it before installation is not being straight with you.
No. It does not increase the likelihood of a strike, and it is non combustible, which is a point in its favor.
Yes. Failed fasteners, degraded sealant, damaged panels and flashing are all repairable, and on exposed fastener roofs a full screw replacement is a common and worthwhile job well before replacement is needed.
