Most US houses on a walkable slope in a mixed climate land on architectural asphalt. The selector exists for the cases that do not: low slope, hail, wildfire, a long holding period, a deck that cannot carry tile.
2:12the line asphalt is no longer permitted belowIRC R905.2.2. Below 2:12 asphalt shingles are not permitted. Between 2:12 and 4:12 they need double underlayment. Confirm the edition your jurisdiction adopted.
The short answer
On the defaults (mixed climate, 4:12 to 8:12, ten-year tenure, mid budget) the pick is architectural asphalt shingle. Below 2:12 it is not asphalt at all. Hail plus a long holding period and a premium budget is where standing-seam metal shows up. Tile and slate are a structural load. A house not framed for them needs an engineer first. This is a selector, not a specification.
Constraints in, a covering out

What this assumed—
A selector, not a specification. Confirm covering against the deck, the wind or hail rating, and the adopted code. HyreRoof does not sell roofs.
Three constraints come before preference
Material choice feels like an aesthetic decision and usually is not. Three constraints eliminate most of the options before taste enters, and working through them in order saves a great deal of time.
Pitch comes first. Below about 3:12 most asphalt shingle manufacturers require a doubled underlayment or prohibit the product entirely; below 2:12 it is a membrane roof. No amount of preference changes that, and installing outside the manufacturer’s slope limits voids the warranty.
Structure comes second. Concrete and clay tile and slate are several times the weight of asphalt. An existing roof structure that was framed for shingle will often not take them without engineering, and that assessment is a structural question rather than a roofing one.
Climate comes third, hail, wind, freeze-thaw, wildfire exposure and salt air each rule things in or out. Only then does appearance, and by that point the list is usually short.
Service life is a band, not a number
Typical service life by covering, plotted at the midpoint of each published range.HyreRoof presentation of typical published service-life ranges. Ranges are bands, not guarantees.
Every material is quoted with a lifespan and every one of those is a range. The range within a material is frequently wider than the gap between adjacent materials, which is why "lasts 30 years" is a weaker claim than it sounds.
The two things that move a covering within its band are ventilation and installation quality. An unventilated attic can take a decade off an architectural asphalt roof, and a shingle nailed high or over-driven has lost its wind rating on the day it went on.
HyreRoof analysis: that is the argument for spending on the installation rather than trading up the material. A well-installed mid-range asphalt roof with new flashing and balanced ventilation reliably outlasts a premium covering fitted badly, and it costs less.

A young category, warranty terms vary widely
Minimum pitches are indicative. The manufacturer instruction and your local code are the binding version.
The tile row is the one most often misunderstood. A fifty-year tile does not mean fifty years without work: the underlayment beneath it is a normal roofing product with a normal life.
If you are in hail country, decide differently
Hail is the one climate factor that should change the material decision outright rather than nudge it, and it is heavily concentrated: 6,848 severe hail reports in Texas alone, against a national total in the tens of thousands.
Asphalt fails functionally under hail, bruising fractures the mat and granule loss exposes it, and that is a claim. Metal generally dents cosmetically while continuing to perform, which is a different outcome for both you and your insurer.
HyreRoof analysis: before choosing, ask your carrier whether they discount an impact-rated covering, and ask whether your policy pays replacement cost or actual cash value on the roof. Both answers can be worth more than the price difference between materials, and neither is something you can work out from a product brochure. In the states at the top of the hail table, this is the first call to make, not the last.
Questions that settle the choice
How long will you own the house?
The single most decisive input. A covering that outlives your ownership by thirty years was bought for somebody else, and buyers rarely pay a premium equal to the extra cost.
What is the pitch, exactly?
Measure it before shortlisting. Low slope removes most options, and finding that out after choosing is an expensive way to learn it.
Will the structure take the weight?
For tile or slate this is a structural assessment, not a roofer’s opinion. Ask before falling in love with a material.
What does your insurer say?
Impact ratings, discounts, and whether the roof is covered at replacement cost or actual cash value. In hail states this can dominate the comparison.
Who nearby can install it, and repair it in ten years?
A material nobody local works with is a material nobody local will repair. This matters most for slate, tile and the newer synthetics.
Do not choose on warranty length
A long material warranty on a badly installed roof is close to worthless, most exclude installation error, and many require balanced ventilation you may not have.
What this selector cannot decide
Whether your structure takes the load
Tile and slate need a structural assessment. This tool flags weight as a constraint; it cannot evaluate your framing.
Local code and HOA restrictions
Fire zones restrict wood shake, and some associations restrict metal or colour. Both are local and both are binding.
Price
Installed cost varies by material, pitch, complexity and local labour several-fold. The cost calculator handles it separately, and neither tool publishes a national average because we could not source one.
Which specific product
It shortlists categories. Within a category, installation quality and the specific manufacturer instructions matter more than the badge.
The rating is a property of a tested assembly, not of the material
The tested assembly is the layer below the category, and it is where the performance you are actually buying is decided. It is also almost never on the bid.
The two standards do not share a scale. A "Class D" shingle means 90 mph under D3161 and 115 mph under D7158. The class letter alone is not a wind speed: the standard has to be named with it.NRCA, Professional Roofing, “Understanding asphalt shingle standards”, Mark S. Graham. Read on 2026-09-05. astm.org returned HTTP 403 to automated retrieval on 5 September 2026. The classes and velocities below were read at NRCA’s Professional Roofing, the trade body’s own explanation of the standards, and are cited that way. We do not quote the standards themselves.
The code says to classify, and to label. IRC R905.2.6.1: "Asphalt shingles shall be classified in accordance with ASTM D3161, TAS 107 or ASTM D7158 to resist the basic wind speed per Figure R301.2(4)." And: "Asphalt shingle wrappers shall be labeled to indicate compliance with one of the required classifications, as shown in Table R905.2.6.1."
There are two standards, and they are not the same test. ASTM D3161 is a fan-induced wind-resistance test method. It classifies shingles as Class A, D or F, with wind speed resistances of 60 mph, 90 mph and 110 mph respectively. ASTM D7158 is an uplift force / uplift resistance method for shingles that carry factory-applied self-sealing strips. It classifies them as Class D, G or H, with basic wind speeds of 115, 150 and 190 mph.
Which one applies depends on the shingle. A shingle must have a factory-applied self-sealing strip to be classified under D7158 at all. Shingles without one are classified under D3161 instead, as the building code requires.
The specification standard is a third thing again. ASTM D3462, “Standard Specification for Asphalt Shingles Made from Glass Felt and Surfaced with Mineral Granules”, sets minimum and maximum values for shingle mass and physical properties, plus minimum Class A fire and wind resistance ratings. A shingle can meet D3462 and still be the wrong wind class for your site; the two statements answer different questions.
The classification assumes a building. The D7158 calculations assume a 3-second gust exposure from ASCE 7, a Risk Category I or II building, ground roughness B or C, and a building 60 feet tall or less. Outside those conditions, exposure D, a taller building, Risk Category III or IV: the classification does not carry over and separate calculation is required. As the standard itself puts it, in the code’s words: "The standard calculations contained in ASTM D7158 assume Exposure Category B or C and a building height of 60 feet or less."
And so: Additional engineering consideration is necessary to verify the appropriateness of ASTM D7158’s wind-resistance classifications if these assumed parameters are exceeded.
What that means when you choose. HyreRoof analysis: a wind class describes a tested assembly, not a shingle. The rating assumes the fastening pattern, the deck and the sealing the test used. A Class H shingle nailed high, nailed with four instead of six, or laid in cold weather so the sealant strip never bonded, is not a Class H roof. This is why the fastening line on a bid is a wind-performance line, and why nobody reads it as one.
How we read this. astm.org returned HTTP 403 to automated retrieval on 5 September 2026. The classes and velocities below were read at NRCA’s Professional Roofing, the trade body’s own explanation of the standards, and are cited that way. We do not quote the standards themselves.
Fire classification belongs to the roof, not to the shingle
Every wildfire-overlay conversation turns on a Class A rating, and the rating is routinely quoted about the wrong object.
What the code actually says
IRC 2021 R902.1, Roof covering materials: "Classes A, B and C roofing required by this section to be listed shall be tested in accordance with UL 790 or ASTM E 108."
On what qualifies without further work: "Class A roof assemblies include those with coverings of brick, masonry and exposed concrete roof deck, as well as ferrous or copper shingles or sheets, metal sheets and shingles, clay or concrete roof tile, or slate installed on noncombustible decks."
And on treated wood specifically: "Fire-retardant-treated wood shakes and shingles shall be treated by impregnation with chemicals by the full-cell vacuum-pressure process, in accordance with AWPA C1, and each bundle shall be labeled to identify the classification of the material."
Model code, locally adopted. Model code. Adoption and amendment are local, and the edition your jurisdiction adopted may differ. Confirm with your building department before relying on any of it.
Why the distinction is the whole point
HyreRoof analysis: the classification belongs to the ASSEMBLY, not to the shingle on its own. A covering rated in one assembly may not carry that rating over a different deck or without the specified underlayment. This is why "Class A shingles" on a bid is not the same statement as a Class A roof, and why the underlayment line matters more than it looks.
The practical consequence is that a bid can be entirely honest, say "Class A shingles", and deliver a roof that is not a listed Class A assembly, because the underlayment was substituted, or the deck is not the one in the listing. Nobody has lied. The sentence was simply about the shingle.
If a fire overlay, an insurer or a lender is the reason you need the rating, ask for the listing: the covering, the underlayment and the deck together, as a named assembly. That is a document the manufacturer publishes and a competent contractor can produce.
The same logic runs through the whole spec
It is why the fastening line matters. Asphalt shingles shall have the minimum number of fasteners required by the manufacturer, but not less than four fasteners per strip shingle or two fasteners per individual shingle., that is the code minimum, and manufacturers routinely require more in high-wind zones. A shingle nailed to the code minimum when its own instructions call for six is outside its listing.
It is why the underlayment line matters. Double underlayment is required on slopes between 2:12 and 4:12.
And it is why the edge details matter. Base flashing requires corrosion-resistant metal of at least 0.019-inch thickness, or mineral-surfaced roll roofing. Drip edges must extend at least 1/4 inch below the sheathing and be mechanically fastened at not more than 12 inches on centre.
The six lines that decide performance, and what their absence means
The material category is the easy decision. These are the lines underneath it, and the last column is why you should care that they are there.
The line
What it should say
What its absence means
Wind classification
The standard and the class together, "ASTM D7158 Class H", not "high wind rated".
The bidder is selecting on price and brand rather than on the site’s design wind speed. On a coastal or open-exposure site this is the most consequential omission on the page.
Fastening pattern
Nails per shingle, and whether it is the manufacturer’s high-wind pattern. Four or six is a real difference.
You are getting the installer’s habit rather than the listing. Since the wind class assumes a fastening pattern, the rating you paid for may not survive the installation.
Underlayment type and coverage
The product, and single or double layer, with the slope it was chosen for.
On anything between 2:12 and 4:12 this is a code compliance question, not a preference. Its absence usually means the slope was not measured.
Ice barrier extent
Where it starts and where it stops, measured: the code says "not less than 24 inches (610 mm) inside the exterior wall line of the building."
In an ice-dam climate this is the difference between a roof that survives February and one that stains the ceiling. Measured from the wrong place, one roll is not enough.
Ventilation
The ratio designed to, the net free area, and a line for intake as well as exhaust.
Most covering warranties condition on adequate ventilation. A bid silent on it has left a warranty exclusion in place at your expense.
Edge metal and flashing
Drip edge at eaves and rakes, and every penetration and wall intersection named. "A drip edge shall be provided at eaves and rake edges of shingle roofs"
Flashing is where roofs leak. A bid that lists shingles and nothing else has priced the visible half of the job.
None of these is exotic. All six are ordinary contract language and all six are routinely missing from residential roofing bids.
HyreRoof analysis, built on the IRC provisions quoted above. We do not review contracts and this is not legal advice; it is a list of questions worth asking before you sign one.
What separates the materials, once you get past the brochure
Service life and price are in every comparison. These five differences are in almost none of them, and they decide how the covering behaves for the twenty years after it is installed.
Illustrative. Relative magnitude only, to show why weight is a gating question for tile and slate and is not one for metal.HyreRoof illustration. We hold no product weight dataset; published weights vary widely within every category and the manufacturer datasheet plus an engineer are the answer.
Repairability, and whether a repair will match
Asphalt is the easiest covering in the world to repair and the hardest to match. Granule colour drifts between production runs and weathering changes it again, so a repair on a ten-year-old roof is visible from the street more or less permanently. Metal panel is the reverse: matching a colour is straightforward, replacing a single panel in the middle of a run is not, because the panels interlock and the fasteners are concealed.
Slate and tile sit differently again. Individual units are replaceable indefinitely by anyone who knows how, which is why century-old slate roofs are still in service, but the number of people who know how is small and shrinking, and that is a practical constraint disguised as a durability advantage.
Thermal movement, and what it does to fasteners
A metal roof grows and shrinks measurably with temperature across the length of every panel. Standing-seam systems are designed for that with concealed clips that let the panel slide; exposed-fastener panels are not, and the movement works the screws and their washers for the life of the roof. That is why exposed-fastener metal has a maintenance schedule and standing-seam largely does not, and why the two get quoted as the same material and are not.
Tear-off, disposal and what the next roof costs
Every covering is also a future disposal cost. Asphalt tear-off is heavy and goes to landfill or, where a plant exists, to asphalt recycling. Tile and slate are heavier still and are handled differently. Metal is light and has a scrap value. None of this shows up in a first-roof comparison, and all of it shows up in the second one.
Layers matter here too. A roof already carrying two layers has to come off; a roof carrying one may not, depending on the adopted code and the condition of the deck. That single fact can move a bid by thousands and it is decided before anyone chooses a colour.
Who nearby actually installs it
This is the constraint that quietly settles most material decisions outside dense metros. A covering three local firms can install is a covering with competitive bidding, available repair, and someone to call under warranty. A covering one firm installs is a sole-source purchase for the life of the roof.
Ask before shortlisting, not after. It costs three phone calls and it is more predictive of your satisfaction than any published service life.
Weight, which is a structural question and not a roofing one
Tile and slate are multiples of the load an asphalt roof puts on the framing. A house framed for shingle frequently will not take them without work, and that assessment belongs to a structural engineer, not to the person selling the covering. The chart below is deliberately relative and illustrative, it exists to show why the question is asked, not to answer it.
Five things to ask for before you commit to a covering
All five are documents that already exist. A contractor who cannot produce them has not specified your roof; a contractor who produces them in a minute has done this properly for years.
The product datasheet, with the wind class on it
Named standard and class together. Check it against the design wind speed for your site, which your building department can give you. This is a thirty-second check and it is the one that most often finds a mismatch.
The manufacturer’s installation instructions for your slope
Not the general brochure: the instructions, which state the minimum slope, the fastening pattern, the high-wind pattern and the underlayment requirements. Installing outside them is the most common way a warranty is voided.
The fire assembly listing, if you need a fire rating
Covering, underlayment and deck together as a named assembly, because that is what the rating attaches to. If a wildfire overlay or an insurer is the reason you are asking, this is the document they will want, not a shingle brochure.
The warranty document, including what voids it
Read the exclusions before the headline number. Ventilation requirements, installation-error exclusions, proration schedules and transferability terms are where a fifty-year warranty becomes a different product from the one on the advertisement.
A structural opinion, if you are considering tile or slate
From an engineer, in writing, before the material is ordered. A roofer’s confidence about your framing is not the same document and will not satisfy anyone later.
Do not accept a class letter without its standard
"Class D" is 90 mph under one standard and 115 mph under the other. A specification that names the letter and not the standard has not specified anything.
Do not treat the warranty length as a service-life estimate
Warranties are commercial instruments with proration schedules and exclusions. They are not predictions, and the two numbers are not comparable across manufacturers.
Why this page can tell you to keep the cheap option
Most material-selection content is published by someone who sells one of the materials. That is not a conspiracy, it is simply who has a reason to write it, and it produces a predictable bias: the premium option is presented as the responsible choice and the standard option as the compromise.
For a large majority of American houses, walkable slope, mixed climate, an owner who will move before the covering wears out, architectural asphalt correctly specified and correctly fastened is not a compromise. It is the right answer, and the money that would have gone into an upgrade buys more performance if it goes into the underlayment, the flashing, the ventilation and the fastening pattern instead.
HyreRoof does not sell or install roofs, ranks no contractors, and takes no referral fee from anyone. That is the only reason this page is free to end on "buy the ordinary one and spend the difference on the details".
And it is not the assembly reference. NRCA publishes The NRCA Roofing Manual, the trade’s reference for assembly detailing. It is a purchased document rather than a free publication, so this site does not quote from it and describes only what is publicly and consistently stated about its role. The controlling text is the manual itself, and a competent contractor has a copy.
The vocabulary, once
ASTM D3462
The specification standard for glass-felt asphalt shingles, mass and physical properties, plus minimum fire and wind ratings. It says the shingle is a proper shingle. It does not tell you which wind class it is.
ASTM D3161
A fan-induced wind test. Classes A, D and F at 60, 90 and 110 mph. Used for shingles that do not carry a factory-applied self-sealing strip.
ASTM D7158
An uplift force and uplift resistance method for sealed shingles. Classes D, G and H at 115, 150 and 190 mph. The classification assumes a specific exposure and building height.
Vasd and Vult
Allowable stress design and ultimate design wind speed. Two different conventions for stating the same wind, differing by roughly the square root of a load factor. Comparing a number in one convention with a threshold in the other is a common and expensive mistake.
UL 790 / ASTM E108
The fire test methods behind Class A, B and C roof classifications. The rating attaches to the assembly that was tested, not to any single component of it.
Assembly
Covering, underlayment and deck as a listed combination. Every fire rating and, in practice, every wind rating is a statement about an assembly. Substituting one layer can end the listing without changing anything you can see.
Self-sealing strip
The factory-applied adhesive band that bonds each shingle course to the one below once solar heat activates it. It is the mechanism the D7158 rating measures, and it is why shingles installed in cold weather may not reach their rated performance until the following summer.
Net weight class
Trade shorthand for the load a covering imposes. It gates tile and slate on existing framing and it is answered by an engineer, not by a roofer or by this page.
Proration
The clause that reduces a warranty’s payout year by year. A fifty-year warranty that prorates from year ten is a ten-year warranty with a long tail, and the schedule is in the document.
Questions this calculator answers
What type of roof do I need?
For most walkable residential slopes in mixed climates, architectural asphalt. Low slope, wildfire overlays, frequent hail, coastal wind and a long holding period are the reasons to look elsewhere. Pitch is the first constraint: below 2:12, asphalt shingles are not a permitted covering.
Is metal always better if I am staying 25 years?
Only when the price ratio is below the life ratio. Run the metal-vs-asphalt tool at your two quotes. At twice the price for twice the life, the result is a dead heat.
Can I put asphalt on a 3:12 roof?
Only with double underlayment (IRC R905.2.2). Below 2:12, no.
Does a Class A shingle make a wildfire-safe roof?
No. The rating is the assembly, covering, underlayment, deck. A Class A shingle on the wrong underlayment is not the listed system.
