Roofing materials divide into two master categories set by your roof’s slope: steep-slope materials for pitched roofs and low-slope (flat-roof) materials for anything under about a 3:12 pitch. Inside those two buckets sit roughly nine material families, from asphalt shingles to single-ply membranes. Which types your roof can actually use is decided first by pitch, then by structure, climate, and budget.
This guide organizes the types of roofing materials the way a roofer sizes up a job: slope first, then form, then material. That order matters, because the same house cannot use a clay tile and a rubber membrane, and pitch is what rules each option in or out. For exact per-square pricing, our complete roofing materials list with per-square pricing runs the numbers material by material.
What are the main types of roofing materials?
The main types of roofing materials are asphalt shingles, metal, clay and concrete tile, slate, wood shakes and shingles, composite or synthetic products, single-ply membranes, built-up and modified bitumen, and spray foam. The first six are steep-slope materials for pitched roofs. The last three are low-slope materials for flat and nearly flat roofs.
Asphalt shingles dominate: they cover roughly 73% to 81% of U.S. homes, per our review of what U.S. roofs are actually made of. Residential metal holds about 17% to 18% and is the fastest-growing steep-slope category, while single-ply membranes lead the low-slope and commercial market.
| Material family | Roof type | Typical lifespan | Relative weight | Fire rating |
|---|---|---|---|---|
| Asphalt shingles | Steep-slope | 15 to 30 years | Light to medium | Class A (fiberglass) |
| Metal (panel or shingle) | Steep and some low-slope | 40 to 70 years | Light | Class A |
| Clay and concrete tile | Steep-slope | 50 to 100 years | Very heavy | Class A |
| Slate (natural or synthetic) | Steep-slope | 75 to 150+ years | Very heavy (natural) | Class A |
| Wood shake or shingle | Steep-slope | 20 to 40 years | Medium | Class C (Class A if treated) |
| Composite / synthetic | Steep-slope | 40 to 50 years | Light to medium | Class A (most) |
| Single-ply membrane (TPO, EPDM, PVC) | Low-slope | 15 to 30 years | Light | Varies by assembly |
| Built-up / modified bitumen | Low-slope | 15 to 30 years | Medium to heavy | Class A (with cap sheet) |
| Spray foam (SPF) | Low-slope | 20 to 30+ years (with recoats) | Light | Varies with coating |
Roof slope decides which materials your roof can use
Slope is the gate. Before cost or looks, your roof’s pitch rules out most of the list. Steep-slope materials shed water by overlapping individual pieces, so they need pitch to work. Low-slope roofs cannot rely on overlap, so they need a continuous waterproof layer instead. Get this backward and the roof leaks no matter how good the material is.
Roofers read pitch as rise over a 12-inch run. The practical thresholds most jurisdictions follow, based on IRC Chapter 9:
- Below 2:12: shingles and tile are off the table. You need a low-slope system: single-ply membrane, modified bitumen, built-up, or spray foam.
- 2:12 to under 4:12: asphalt shingles are allowed with a doubled underlayment (IRC R905.2.2). Metal panels and standing seam also work here.
- 4:12 and steeper: the full steep-slope menu opens up, including tile and slate where the structure can carry the weight.
Weight is the second gate. A concrete tile roof can weigh 900 to 1,200 pounds per square (100 square feet), while asphalt runs about 230 to 430 pounds. A frame built for shingles may need reinforcement before it can hold tile or slate, which is a structural cost that sits outside the material price.
Steep-slope roofing materials (pitched roofs, 3:12 and up)
Steep-slope materials are the six families used on pitched residential roofs: asphalt shingles, metal, clay and concrete tile, slate, wood, and composite. They share one rule: each piece overlaps the one below so water runs down the surface rather than sitting on it. They differ sharply on lifespan, weight, and cost.
Asphalt shingles
Asphalt shingles are fiberglass mats coated in asphalt and mineral granules, sold in three tiers: three-tab (flat, entry level), architectural or laminated (dimensional, the default today), and luxury or designer (thick, slate or shake look). Architectural shingles now make up about 95% of asphalt shingle demand. They last 15 to 30 years and carry a Class A fire rating.
Metal roofing
Metal roofing comes in three forms: standing seam panels with hidden fasteners, exposed-fastener panels (corrugated and R-panel), and metal shingles or tiles that mimic slate, shake, or clay. Steel is about 82% of the residential metal market, with aluminum, zinc, and copper filling the rest. Metal lasts 40 to 70 years, sheds snow, and weighs only 50 to 150 pounds per square.
Clay and concrete tile
Clay and concrete tiles are molded, interlocking units common across the Sun Belt. Clay holds color for a century and resists salt air; concrete costs less and copies clay, wood, or slate profiles. Both last 50 to 100 years and carry Class A fire ratings, but they are very heavy (600 to 1,200 pounds per square) and usually need a 4:12 or steeper pitch plus a structural check.
Slate
Slate is quarried stone split into thin tiles, the longest-lasting roofing material at 75 to 150 years or more. It is naturally fireproof and never rots. The tradeoffs are weight (800 to 1,500 pounds per square) and cost, which sits at the top of the market. Synthetic slate copies the look in molded polymer at a fraction of the weight, lasting 40 to 50 years.
Wood shakes and shingles
Wood roofing uses cedar, redwood, or pine in two forms: hand-split shakes (thick, textured) and sawn shingles (smooth, uniform). It lasts 20 to 40 years and ages to a silver-gray patina many owners want. Untreated wood carries only a Class C fire rating, so many wildfire-zone codes require pressure-treated Class A wood or ban it outright.
Composite and synthetic
Composite or synthetic shingles are molded from engineered polymers, often with recycled content, to copy slate or cedar shake without the weight. They last 40 to 50 years, weigh 150 to 300 pounds per square, and most carry Class A or Class B fire ratings. They give a home the high-end look on a frame that could never hold real slate or tile.
| Steep-slope material | Lifespan | Weight (per square) | Relative cost tier | Min pitch |
|---|---|---|---|---|
| Asphalt shingles | 15 to 30 yr | 230 to 430 lb | $ (lowest) | 2:12 (doubled underlayment) |
| Wood shake / shingle | 20 to 40 yr | 200 to 350 lb | $$ | 3:12 |
| Metal (panel or shingle) | 40 to 70 yr | 50 to 150 lb | $$ to $$$ | 2:12 to 3:12 |
| Composite / synthetic | 40 to 50 yr | 150 to 300 lb | $$$ | 4:12 |
| Clay / concrete tile | 50 to 100 yr | 600 to 1,200 lb | $$$ to $$$$ | 4:12 |
| Slate (natural) | 75 to 150+ yr | 800 to 1,500 lb | $$$$$ (highest) | 4:12 |
Low-slope and flat roofing materials (below 3:12)
Low-slope materials cover flat and nearly flat roofs where water drains slowly, so they form one continuous waterproof surface rather than overlapping pieces. The five main types are single-ply membranes (TPO, EPDM, PVC), modified bitumen, and built-up roofing, plus spray polyurethane foam. Single-ply leads the category and is the fastest-growing roofing type overall. For real-world durability data, see our flat roof materials compared by failure data.
TPO is a white, heat-reflective thermoplastic sheet with heat-welded seams, the most-installed commercial single-ply, chosen by about 37% of single-ply contractors. PVC is a similar welded sheet with better grease and chemical resistance, common on restaurants. EPDM is black synthetic rubber, adhered or ballasted, valued for cold-climate flexibility. Modified bitumen is asphalt reinforced with polymers, torch-applied or self-adhered in rolls. Built-up roofing (BUR) layers felt plies in bitumen under gravel, the traditional tar-and-gravel roof. Spray foam (SPF) is a sprayed, monolithic layer with no field seams, recoated every 10 to 15 years.
| Low-slope material | Form | Lifespan | Standout trait |
|---|---|---|---|
| TPO | Welded single-ply sheet | 15 to 25 yr | Reflective, low cost, most common |
| PVC | Welded single-ply sheet | 20 to 30 yr | Grease and chemical resistant |
| EPDM | Rubber single-ply sheet | 20 to 30 yr | Cold-climate flexibility |
| Modified bitumen | Rolled asphalt sheet | 15 to 20 yr | Redundant, repairable plies |
| Built-up (BUR) | Layered plies + gravel | 15 to 30 yr | Multiple waterproof layers |
| Spray foam (SPF) | Liquid-applied, monolithic | 20 to 30+ yr | No seams, adds insulation |
Types of roofing materials by form
Beyond the material itself, every roofing product takes one of six physical forms, and the form is what decides where it can go. Two products made of metal can behave completely differently: a metal shingle is a steep-slope unit, while a mechanically attached metal panel can run down to a low pitch. Sorting materials by form is the fastest way to see what fits a given roof.
| Form | How it is made | Materials in this form | Fits |
|---|---|---|---|
| Individual shingles / units | Small overlapping pieces nailed in courses | Asphalt, wood, slate, composite, metal shingles | Steep-slope only |
| Panels / sheets | Long formed sheets fastened to the deck | Standing seam, corrugated, R-panel metal | Steep and some low-slope |
| Tiles | Molded interlocking units | Clay, concrete, some metal and composite | Steep-slope (usually 4:12+) |
| Membranes | Large sheets welded or adhered together | TPO, PVC, EPDM, modified bitumen | Low-slope / flat |
| Built-up layers | Alternating plies of felt and bitumen | BUR (tar and gravel) | Low-slope / flat |
| Liquid-applied / coatings | Sprayed or rolled fluid that cures solid | Spray foam, silicone and acrylic coatings | Low-slope / flat |
Specialty types: solar shingles, green roofs, and cool roofs
Three specialty categories cut across the standard list. Solar shingles are photovoltaic cells built into shingle-shaped units that generate power while acting as the roof surface, an alternative to bolt-on panels. Green or living roofs layer soil and plants over a waterproof membrane on low-slope structures rated for the load. Cool roofs are any material finished in reflective coatings or light colors to cut heat gain.
These are less about a new raw material and more about a function added to an existing form. A cool roof can be a white TPO membrane or a reflective-granule asphalt shingle. A green roof still needs a proven low-slope membrane underneath. Solar shingles remain a small share of installs but pair a roofing material with on-site power generation.
How to choose the right roofing material type
Choosing a type is a process of elimination in a fixed order. Work through four filters and the field usually narrows to two or three real options. This sequence stops homeowners from falling for a material their roof cannot physically carry or drain.
- Slope: measure pitch first. Under 3:12 sends you to low-slope systems; 4:12 and up opens the full steep-slope menu.
- Structure: confirm the frame can hold the weight. Tile and slate often need reinforcement that shingles and metal do not.
- Climate and code: match fire rating, wind zone, and hail exposure. Wildfire zones may require Class A; hurricane zones reward impact-rated and high-wind products.
- Budget and hold time: weigh upfront cost against how long you plan to own the home, since a 70-year metal roof rarely pays back on a 5-year hold.
Once the list is short, compare the finalists head to head. Our roofing materials comparison scored by priority ranks the survivors on cost, lifespan, and weight so the last choice is a decision, not a guess.

Frequently asked questions
What are the most common types of roofing materials?
The most common types are asphalt shingles, metal, clay and concrete tile, slate, wood, and composite for pitched roofs, plus single-ply membranes (TPO, EPDM, PVC), modified bitumen, built-up roofing, and spray foam for flat roofs. Asphalt shingles alone cover roughly 73% to 81% of U.S. homes, making them the default material most people picture.
What is the longest-lasting type of roofing material?
Natural slate is the longest-lasting roofing material, commonly serving 75 to 150 years or more, followed by clay tile at 50 to 100 years. Metal runs 40 to 70 years and synthetic slate 40 to 50. Asphalt shingles, the shortest-lived common type, last 15 to 30 years. Longevity tracks closely with cost and weight.
What type of roofing material is best for a flat or low-slope roof?
Flat and low-slope roofs need a membrane or fluid system, not shingles. Single-ply membranes lead: TPO for reflective low cost, PVC for grease and chemical resistance, and EPDM rubber for cold-climate flexibility. Modified bitumen, built-up roofing, and spray foam are the other low-slope options. Any material relying on overlapping pieces will leak below about a 2:12 pitch.
What is the cheapest type of roofing material?
Three-tab asphalt shingles and rolled roofing are typically the cheapest roofing materials by upfront cost, which is a large part of why asphalt covers most U.S. homes. The lowest price often carries the shortest lifespan, so the cheapest option per square is not always the cheapest per year of service. Exact figures vary by region and roof size.
How do I know which roofing material types my roof can use?
Start with slope. Measure your roof’s pitch as rise over a 12-inch run: under 2:12 rules out shingles and tile and requires a low-slope membrane, while 4:12 and up allows the full steep-slope menu. Then check whether the structure can carry heavy options like tile or slate. Slope and weight eliminate most of the list before cost enters.
What is the difference between roofing material types and forms?
A material type is what the roofing is made of, such as metal, asphalt, or clay. A form is the physical shape it takes: a shingle, a panel, a tile, a membrane, a built-up layer, or a liquid coating. The same material can appear in several forms, and the form, not just the material, decides which roof slopes it fits.
