There are three kinds of asphalt shingle and about six other materials people call shingles. This is what each costs, how long each lasts, and which ones make sense in Triangle heat, humidity and hail.
Nine in ten roofs we quote in the Triangle are asphalt. The choice inside that is smaller than it looks.
Relative cost. $ of three.
A single layer of asphalt cut into three tabs so it reads as separate shingles from the street. Lightest, cheapest, and the shortest lived of the three. It sits at the bottom of the 15 to 30 year asphalt range rather than the top. Related: Hip and ridge shingles.
Right for. Rental property, a flip, or a roof you need sound and legal for the next decade rather than the next thirty years. Related: Roof valley types.
Relative cost. $$ of three.
Multiple layers of asphalt-coated fiberglass laminated together, which is where the depth and the shadow line come from. Heavier, and the extra mass is most of why it lasts longer. InterNACHI puts architectural asphalt at 30 years.
Right for. Almost every house in the Triangle. If someone quotes you a roof without saying which type, this is what they mean, and it is the right default.
Relative cost. $$$ of three.
The thickest asphalt made, built to imitate slate or hand-split shake. More layers again, noticeably more weight, and a price that starts to overlap with real materials.
Right for. A period house where the roof is part of the architecture, or anywhere a homeowners association has opinions about how the street looks.
Luxury is a style choice most people never make. This is the one almost every Triangle homeowner actually makes.
| 3-tab | Architectural | |
|---|---|---|
| Construction | A single layer of asphalt-coated fiberglass, cut into three equal tabs | Multiple layers of asphalt-coated fiberglass, laminated together |
| Also called | Strip shingle | Dimensional, or laminated |
| How it reads from the street | Flat and even | Dimensional, with a shadow line |
| Why it exists | The original asphalt strip shingle: lightweight and easy to install | Introduced in the 1970s and 80s to give the look of slate or cedar shake without the weight, cost and maintenance |
| Warranty | The shorter of the two | GAF says some architectural shingles may be covered by better warranties than three-tab shingles |
| Published lifespan | The bottom of the 15 to 30 year asphalt range | InterNACHI puts architectural asphalt at 30 years |
Construction, naming, origin and warranty wording from GAF, the manufacturer behind most of what we install. Lifespan from InterNACHI. There is no weight or wind-speed row here on purpose: the figures everyone else prints for those come from contractor blogs citing one another, and no manufacturer or test body publishes them as a grade-wide comparison.
On wind ratings. Asphalt shingles are rated under ASTM D7158, and the published classes are A at 60 mph, D at 90, F at 110, G at 120 and H at 150. The class is printed on the bundle wrapper, so it is a thing you can check rather than infer from the grade. What it does not tell you is how the roof will behave in ten years: IBHS found more than 40 percent of roofs older than five years took damage at relatively low gust speeds, and found shingles rated to 150 mph performed poorly in gusts that likely reached only 115. The research is here, and we have written up what wind damage looks like separately. Ask for the class on the bundle, not the grade name.
The part nobody mentions until the claim. If a storm takes off a 3-tab roof, a claim is normally settled on the roof surfacing that was damaged, which is the one you had. Upgrading to architectural at that point usually means paying the difference yourself, and homeowners find this out after the adjuster has already written the number. It is worth asking your insurer how your policy handles an upgrade before you choose, not after. Our guide to what insurance covers on a roof in North Carolina goes through how these are settled here.
So which one. Architectural, for almost everyone, and that is not a nudge toward the dearer product. It is the default the whole market has moved to, the price gap has narrowed, and GAF's own position is that the better warranties sit on that side. 3-tab still earns its place in three situations: a rental where the roof needs to be sound rather than impressive, a property you are selling inside a couple of years, and a repair matching an existing 3-tab roof you are not ready to replace.
Ranked the way a quote would present them, cheapest first.
| Material | Installed cost per sq ft | Lifespan | The short version |
|---|---|---|---|
| Asphalt shingle | $3.50 to $5.50 | 15 to 30 years | The default, and usually right |
| Metal | $7 to $22 | 45 to 100 years | Outlives two asphalt roofs |
| Concrete tile | $2 to $4 | 30 to 50 years | Cheap, but heavy |
| Clay or ceramic tile | $2 to $10 | 20 to 100 years | Near permanent, brittle |
| Wood shake | $4.80 to $5.25 | 20 to 30 years | Character, needs upkeep |
| Synthetic | $1 to $15 | Up to 50 years | Slate look, light weight |
| Rubber | $25 to $40 | Up to 50 years | Flat and low-slope only |
| Solar shingle | $21.50 | Up to 30 years | Power first, payback second |
Cost and lifespan ranges from This Old House. Ranges are national. Triangle pricing sits inside them, and the spread within each material is mostly product grade and roof complexity.
Three things make a Triangle roof different from the national averages above, and none of them are in the brochure.
Hail. Wake County logged 69 hail events between 2020 and 2025. Impact resistance is graded UL 2218 Class 1 to Class 4, and Class 4 is the one worth paying for. Several insurers discount the premium for it, which shortens the payback considerably.
Heat and humidity. Asphalt ages by losing granules, and it loses them faster on a hot roof with poor ventilation than on a cool one. Ventilation is not an upsell on a Carolina roof. A roof that runs hot will give you the bottom of the 15 to 30 year range rather than the top.
Weight. Concrete tile is cheap per square foot and rated past 150 mph, but at roughly 900 pounds per square most framing around here needs checking first. That check is not expensive. Discovering the problem afterwards is.
Four questions that settle it faster than a catalog will.
Under ten years, architectural asphalt and stop thinking about it. Over twenty, run the numbers on standing seam metal, because one metal roof against two asphalt ones is a closer contest than the sticker suggests.
If yes, ask specifically for a Class 4 impact rated shingle and ask your insurer what it does to the premium before you choose.
On a simple gable nobody will ever notice luxury shingles. On a steep period roof visible from the street, they are the difference between right and nearly right.
Asphalt, metal and synthetic are all light. Tile and concrete are not. If you want either, the structural question comes before the color question.

Architectural asphalt, sometimes called dimensional or laminate. It is two layers of asphalt bonded together and it is what most Triangle homes have.
The published range is 15 to 30 years. In practice ventilation and hail decide where in that range you land. A well ventilated architectural roof that misses the storms will reach the top of it. A hot attic and one bad hail season will not.
Architectural, for almost everyone. It is heavier, lasts longer and the price gap is smaller than it used to be. 3-tab still makes sense on a rental or a property you are about to sell.
Yes, but far less than they used to. GAF still makes and sells a three-tab shingle, so this is not a discontinued product, and we will fit one where it is the right answer. What has changed is the default: architectural is now what most quotes mean when they just say asphalt, and most of the 3-tab we touch in the Triangle is a repair on a roof that already has it.
Not within the same plane, and it is rarely a good idea across planes either. The two are different thicknesses and are laid to different exposures, so the courses do not line up and the join leaves a visible step. The question almost always comes up on a repair, where the honest answer is that a patch of architectural on a 3-tab roof will be obvious from the street, and matching the existing shingle is usually the better call even though it is the older product.
Thirty years is the published figure from InterNACHI, and it is the number the warranties are written around. Whether a particular roof gets there is decided mostly by ventilation and by storms rather than by the shingle. IBHS found more than 40 percent of roofs older than five years sustained damage at relatively low gust speeds, which is a reminder that the published lifespan assumes nothing dramatic happens. A hot attic and one bad hail season will take years off it.
It is the top rating in the UL 2218 test, where a steel ball is dropped on the shingle from a set height. Class 4 survives the hardest version of that test. In a hail belt it is the most useful line on a spec sheet, and many insurers discount for it.
Lighter colors and good ventilation matter more than the shingle brand. Heat ages asphalt by driving granule loss, and a cool roof deck is the cheapest way to slow that down.
North Carolina allows a second layer in many cases, and we generally advise against it. You cannot inspect the decking underneath, the extra layer runs hotter, and the next replacement costs more because two layers have to come off.
