The facts behind the roof decision. Take your time, compare your options, and know what to ask before work starts.

**Key points**

- Asphalt shingle installs at about $3.50–$5.50 per sq ft and lasts 15–30 years in Texas; standing seam metal installs at $11–$15 ($1,100–$1,500 a square) and lasts 40–70. Stone-coated steel installs at the same $11–$15 and carries the Mammoth Two Tusk warranty: Mammoth's 10-year workmanship warranty plus the manufacturer's limited lifetime material warranty.
- Hail: Class 4 shingles resist most of it; metal shrugs off more; stone-coated steel hides the marks. Nothing is impervious to hail, and both can earn an insurance discount.
- Heat: metal reflects and sheds it, and what that saves depends on the color, the finish and the attic. On either roof, attic ventilation matters more than the surface.
- HOAs: everyone accepts shingle; many north San Antonio HOAs refuse bare standing seam and accept stone-coated steel, which reads as shake, tile or slate from the street.
- The honest rule: staying under ten years, a Class 4 shingle is the smarter money; staying longer in hail country, buy the metal roof once.

## The roof decision, explained.

Both are good roofs. We install both materials and we will happily put either on your house. The wrong one is simply the one that does not fit your house, your HOA, your hail risk or how long you are going to live under it. This is the comparison the way we run it on the driveway: seven questions, a straight answer to each, and the number behind it.

## How long each one lasts in Texas sun

Asphalt shingles last 15 to 30 years here. Where a roof lands in that range depends less on the shingle than on the attic under it: a Class 4 architectural shingle over a properly ventilated attic sits at the top; a three-tab shingle over a 140°F attic sits at the bottom, and can curl in twelve. [Standing seam metal](https://mammothroofs.com/services/metal-roofing/standing-seam/) runs 40 to 70 years, with the painted finish rather than the steel being what ages. [Stone-coated steel](https://mammothroofs.com/services/stone-coated-steel/) installed as a complete system is the roof we call [the Forever Roof](https://mammothroofs.com/forever-roof/), and it carries the Mammoth Two Tusk Limited Lifetime Warranty: a limited lifetime manufacturer warranty on the panels, and 10 years on our workmanship.

Over thirty years of ownership that is one metal roof against two shingle roofs, and the second shingle roof is bought at a price nobody can predict.

## Hail: what actually happens to each roof

Hail does two things to an asphalt shingle. It knocks the granules off, exposing the asphalt to UV so it dries and cracks, and on a big enough stone it crushes the fibreglass mat underneath, which is the bruise an inspector feels with a thumb. The leak usually arrives two winters later. [Class 4 impact-rated shingles](https://mammothroofs.com/services/shingle-roofing/), tested by dropping a 2-inch steel ball from 20 feet without cracking the back, resist most of what falls on San Antonio, but a big enough stone marks anything.

Metal takes hail differently. Standing seam panels shrug off most of it; very large stones can dent a panel, which is cosmetic on a steel roof and is the reason 24-gauge outlasts 26. Stone-coated steel adds a granule finish that hides the marks smooth metal would show. It is not impervious to hail; nothing is. What both metal roofs buy you is fewer claims, not none, and the Class 4 rating many Texas insurers discount every year.

We have replaced shingle roofs after their third hail event in eight years on the same north-side street where the metal roofs were untouched. The discount is nice; the storms you sleep through are the real return.

## Wind: the seal strip versus the clip

Wind lifts an asphalt shingle at the seal strip, the adhesive line that bonds each course to the one below. Once the strip has aged in the heat, a north wind gets under the edge, breaks the bond and folds the shingle back; it may re-seal or it may not. The six-nail pattern, ring-shank nails and a good seal strip narrow the gap, which is why we nail six per shingle on every roof and why "four to save time" is a red flag on any quote.

Standing seam panels are held by concealed clips that let the panel expand and contract without stressing a fastener, and stone-coated steel panels interlock with their neighbors on four sides over a batten grid. The wind has nothing to get under, which is why after the August 2026 north San Antonio wind event the metal roofs we inspected were intact while the shingle roofs around them had lifted courses.

## Heat and the cooling bill

A dark asphalt roof absorbs the sun and passes the heat into the attic, and the air conditioner pays for it every afternoon. Metal reflects a large share of that energy and, because it is thin, sheds what it did absorb quickly after sunset. How much that saves on the cooling bill depends on the color, the finish and the attic. Lighter shingle colors help a little.

[Ventilation helps far more](https://mammothroofs.com/guides/roof-ventilation/), on either roof. Intake at the soffits and exhaust at the ridge, sized to the attic, drops the attic temperature by tens of degrees, extends the life of any shingle and is on every Mammoth quote. If you want a lower cooling bill and are keeping the shingle roof, fix the ventilation first.

## What each costs, installed

In the 2026 San Antonio market asphalt shingle installs at roughly $3.50–$5.50 per square foot; standing seam metal and stone-coated steel at [$11–$15 ($1,100–$1,500 a square)](https://mammothroofs.com/services/metal-roofing/#metal-roof-cost). On a typical 2,000 sq ft single-story home with 22–26 squares of roof, that is about $8,000–$13,000 for shingle against $24,000–$38,000 for either metal. Metal costs two to three times more up front and is usually the last roof the house needs; whether that is a bargain or an extravagance depends entirely on how long you will own the house.

|  | Architectural / Class 4 shingle | Standing seam metal | Stone-coated steel (Forever Roof) |
| --- | --- | --- | --- |
| Installed cost per sq ft | $3.50–$5.50 | $11–$15 | $11–$15 |
| Typical life in Texas | 25–30 years | 40–70 years | Limited lifetime manufacturer warranty on the panels |
| Hail | Class 4 resists most; bruising still happens | Very good; very large hail can dent | Class 4; stone finish hides marks |
| Wind | Seal strips age; six nails help | Concealed clips; excellent | Interlocks on four sides; excellent |
| Weight | Heaviest of the three | Light | About 1.5 lb per sq ft; no structural work |
| Look / HOA | Everyone accepts it | Modern, ranch, commercial; some HOAs refuse | Shake, tile or slate look; most HOAs approve |
| Noise in rain | Quiet | Quiet over a solid deck and underlayment | Quiet; batten grid and stone finish |
| Warranty | Manufacturer + Mammoth 10-year workmanship | Manufacturer finish + Mammoth 10-year workmanship | Manufacturer limited lifetime + Mammoth 10-year workmanship |

## HOAs, color and what the street sees

Every HOA accepts shingle. Many north San Antonio HOAs, including several in Stone Oak and the Dominion, refuse bare standing seam on a house and accept stone-coated steel, because from the street it reads as shake, tile or slate. Some covenants specify color families and profiles. We check the covenants before we quote a metal roof and bring the samples to the house, because the wrong panel bought before the HOA letter is an expensive mistake. We check them the same way for [metal roofing in Austin](https://mammothroofs.com/locations/austin/metal-roofing/).

## Three things people believe about metal that are not true

#### "A metal roof is loud in the rain."

Not over a solid deck with [underlayment](https://mammothroofs.com/blog/what-is-the-best-underlayment-for-roofing/), which is how we install every one. The tin-roof sound people remember comes from panels screwed over open purlins on a barn. Stone-coated steel, with its batten grid and stone finish, is about as quiet as shingle.

#### "Metal attracts lightning."

Lightning strikes the tallest object regardless of what it is made of. A metal roof is non-combustible, which is the safer side of that equation.

#### "You can always install metal over the old shingles."

Sometimes, on a single sound layer after an inspection, and we will say when it is a bad idea. Most homes get a full tear-off so the deck is inspected and repaired; metal over a rotten deck is a rotten roof with a nice hat, and the price difference is smaller than people expect.

## Resale and how long you will stay

Selling in five years: a Class 4 architectural shingle is usually the smarter money, and the insurance discount it earns is a selling point. Staying fifteen or more: a metal roof pays back in the replacement you never buy, the cooling you never pay for and the hail seasons you sleep through. Either way, [a transferable warranty](https://mammothroofs.com/guides/roofing-warranties-explained/) is a line item on the listing; ask how the transfer works before you sign.

## Slate roof vs asphalt shingles

Natural slate is [the longest-lasting roof you can buy](https://mammothroofs.com/blog/what-is-the-most-durable-roofing-material/). Slate can last 75 to 100 years or more with little upkeep; it resists mold and algae, it does not burn, and it comes in natural grays, greens and even purples. Asphalt shingles last 15 to 30 years in Texas, come in a far wider range of colors and styles, and cost much less to buy and install.

The catch is everything that comes with that long life. Slate is heavy, so the framing may need reinforcing before it goes on; it is fragile underfoot; and it has to be laid and repaired by a specialist crew, which makes the installation and every later repair expensive. Asphalt shingles are light, go on in a day or two and are simple to repair, though they need repairs more often over their life.

|  | Asphalt shingle | Natural slate |
| --- | --- | --- |
| Cost | Affordable | Premium: higher materials and labor |
| Typical life in Texas | 15–30 years | 75–100 years or more |
| Weight | Light | Heavy; the framing may need reinforcing |
| Installation | A day or two | Specialist crews only |
| Upkeep | Regular; simple repairs | Minimal; repairs need a specialist |
| Look | A wide range of colors and styles | Natural stone: grays, greens, purples |
| Environment | Petroleum-based; recyclable in some areas | Natural stone, little processing; a long life means less waste |

Slate-look shingles, thicker architectural shingles cut to mimic slate, give the appearance for a fraction of the price, but they last like any other shingle. Stone-coated steel comes in a slate profile too: it weighs about 1.5 pounds per square foot, carries a Class 4 impact rating and needs no structural work.

The honest answer: if the structure can carry it, the budget allows it and you want natural stone, slate is a lifetime roof. For most Texas homes, a Class 4 shingle is the affordable choice and stone-coated steel is the long-life choice with the slate look.

## The best roofing material for a Texas home.

There is no single best roof for Texas, but there is a best roof for a given house, budget and length of stay. Asked that way, the answers line up with everything above.

- **For hail:** a Class 4 roof, either a Class 4 shingle or stone-coated steel, which many Texas insurers discount. Standing seam shrugs off most hail, but very large stones can dent it.
- **For heat:** metal reflects the sun and sheds heat fastest after sunset. On any roof, the attic ventilation matters more than the surface.
- **For the budget:** an architectural or Class 4 shingle, at about $3.50 to $5.50 per square foot installed.
- **For the longest stay:** standing seam or stone-coated steel, at $11 to $15 per square foot, usually the last roof the house needs.
- **For the look:** clay or concrete tile on Mediterranean and Spanish houses, slate on estate homes, and stone-coated steel when an HOA wants a shake, tile or slate profile.

Tile, composite and wood shake each have a place too; the questions below cover them. For what each costs on a whole roof, see our guide to [what a new roof costs](https://mammothroofs.com/guides/what-does-a-new-roof-cost/).

## Frequently asked

Is a metal roof worth it in San Antonio?
If you will own the house long enough to buy a second shingle roof, usually yes: one roof instead of two, lower cooling bills and fewer hail claims. If you are selling within ten years, a Class 4 shingle is usually the better money.

Will a metal roof lower my insurance?
Class 4 impact-rated roofs, including stone-coated steel, qualify for a discount with many Texas insurers. The amount varies by carrier; we give you the certificate and your agent applies it. A Class 4 shingle earns the same kind of discount.

Does a metal roof make the house hotter or cooler?
Cooler. Metal reflects sunlight and sheds heat fast after sunset; how much that saves depends on the color, the finish and the attic. Attic ventilation matters more than the surface on either roof.

Which lasts longer, metal or shingle?
Metal: 40–70 years for standing seam against 15–30 for asphalt shingle in Texas. Stone-coated steel installed as a system carries the Mammoth Two Tusk Limited Lifetime Warranty: a limited lifetime manufacturer warranty on the panels, and 10 years on our workmanship.

Can I put a metal roof on a house with an HOA?
Often, with stone-coated steel; many HOAs that refuse bare standing seam approve a shake, tile or slate profile. We check the covenants before we quote.

What about a real slate roof?
Natural slate can last 75 to 100 years or more with little upkeep, but it costs much more than shingle, it is heavy enough that the framing may need reinforcing, and it takes a specialist crew to lay and repair. For the slate look without the weight, stone-coated steel comes in a slate profile, and slate-look shingles cost less again but last like any shingle.

What about clay or concrete tile?
Tile suits Mediterranean, Spanish and Southwestern houses and can last 50 to 100 years. It is heavy, so the framing may need reinforcing; it costs more to install than shingle; and it can crack under heavy hail or foot traffic. Stone-coated steel gives the tile look without the weight.

Are synthetic or composite shingles worth a look?
They are made to resist hail and fading and to look like slate, shake or tile. They are light enough that the roof needs no extra framing, and they cost more than asphalt but less than slate or tile. Availability varies by manufacturer, so ask for the specification sheet and the warranty document.

Is wood shake a good idea in Texas?
Rarely. Shake looks warm on a rustic house, but it needs treating against fire, rot and insects, and it is a poor match for humid, storm-heavy weather. Stone-coated steel in a shake profile gives the look without the upkeep.

Standing seam or corrugated metal?
Two roofs for different jobs. [Standing seam](https://mammothroofs.com/services/metal-roofing/standing-seam/) hides its fasteners: concealed clips hold the panels, so no screws are on show. [Corrugated and R-panel](https://mammothroofs.com/services/metal-roofing/corrugated-metal/) are exposed-fastener panels, the workhorse for barns, porches, workshops and ranch homes; the screws are the leak points, so check them every few years. If the roof is the front of the house and you want no screws on show, start with standing seam.
