If you are replacing an old roof or building a new structure, you have likely compared different materials. Two common options are traditional asphalt shingles and modern PVC roofing sheets. So the question arises: Is PVC roofing better than shingles? The answer depends on your priorities – longevity, maintenance, weather resistance, and the type of building you are roofing.
As a manufacturer of PVC roofing sheets, we have seen thousands of customers switch from shingles to PVC for specific applications (patios, carports, low‑slope roofs, agricultural buildings, and even some residential roofs). Below, we compare the two materials honestly, so you can decide which fits your project best.
Asphalt shingles are the most common roofing material in North America. They consist of a fiberglass or organic mat coated with asphalt and covered with mineral granules. They are designed for sloped roofs (typically a pitch of 4:12 or steeper) and come in three‑tab or architectural styles.
PVC roofing sheets are rigid, lightweight panels made from polyvinyl chloride with UV stabilizers, impact modifiers, and colorants. They are available in thicknesses from 1.2 mm to 3 mm and in various profiles: corrugated, trapezoidal, tile‑look, or flat. PVC roofing can be used on sloped roofs, low‑slope roofs, and even curved structures.
Asphalt shingles typically last 15 to 25 years. They are prone to granule loss, curling, cracking, and algae growth in humid climates. High winds can lift shingles, and hail can crack them.
PVC roofing sheets, when properly manufactured with full‑body UV stabilization, last 20 to 30+ years. They resist cracking, do not curl, and are not affected by algae or moss. High winds are less of an issue because the sheets are fastened in long panels with fewer vulnerable edges.
Winner for longevity: PVC roofing.
Asphalt shingles require regular inspection. Damaged or missing shingles must be replaced individually. Moss and algae may require chemical treatment. Over time, granules wash off into gutters.
PVC roofing is nearly maintenance‑free. An occasional hose‑down or gentle wash with mild soap keeps it clean. There are no granules to lose, no algae to treat (unless in very humid climates, where a simple wash suffices), and no individual shingles to replace. If a sheet is damaged, you remove the whole panel and install a new one – a straightforward process.
Winner for low maintenance: PVC roofing.
Rain – Both materials are waterproof when installed correctly. However, shingles rely on overlapping layers; high wind‑driven rain can sometimes sneak under shingle tabs. PVC sheets overlap or interlock, creating a more secure barrier.
Wind – Asphalt shingles are rated for wind speeds up to 110–130 mph (depending on quality). PVC sheets, when properly fastened, can withstand similar or higher wind speeds because they are continuous panels.
Hail – Shingles can be dented, cracked, or lose granules from hail. PVC sheets, especially those 1.5 mm or thicker, resist hail impact very well (tested up to 1‑inch hailstones).
Fire – Asphalt shingles are Class A fire‑rated (the highest). PVC is naturally flame‑retardant and also achieves Class A or B ratings, depending on formulation. Both are safe, but PVC does not produce flaming drips that can spread fire.
Salt spray (coastal areas) – Asphalt shingles degrade faster near the ocean due to salt and humidity. PVC is completely resistant to salt corrosion, making it a superior choice for beach houses or coastal structures.
Winner for overall weather resistance: PVC roofing (especially in coastal, hail‑prone, or high‑wind areas).
Asphalt shingles weigh approximately 70–90 kg per square meter (15–18 lbs per square foot) for a typical roof system including underlayment.
PVC roofing sheets weigh only 2–5 kg per square meter (0.4–1 lb per square foot). This huge difference means:
Many existing roofs can be re‑covered with PVC without reinforcing the structure.
Installation is safer and faster because panels are light.
Transportation costs are lower.
Winner for lightweight construction: PVC roofing.
Asphalt shingles require skilled labor. Installation involves laying underlayment, starter strips, each row of shingles with precise nailing, and ridge caps. It is time‑consuming and generates waste (cut shingles, packaging).
PVC roofing sheets are simpler to install. You cut sheets to length with a circular saw or jigsaw, lay them on purlins, overlap adjacent sheets, and fasten with rubber‑washed screws. A two‑person crew can cover a large area in one day. DIY installation is feasible for many homeowners.
Winner for ease of installation: PVC roofing.
Asphalt shingles come in many colors and architectural styles, including dimensional shingles that mimic wood shake or slate. They are a familiar, traditional look for houses.
PVC roofing sheets are available in corrugated, trapezoidal, and tile‑look profiles that closely resemble clay or concrete tiles. Colors include terracotta, brown, grey, green, black, and white. For a modern or Mediterranean aesthetic, PVC tile‑look sheets can be very attractive. However, for a classic “shingle look,” asphalt still wins.
Winner for traditional shingle appearance: Asphalt shingles.
Winner for tile or industrial look: PVC roofing.
Asphalt shingles absorb heat, especially dark colors, raising attic temperatures. Some “cool roof” shingles with reflective granules exist, but they are more expensive.
PVC roofing has lower thermal conductivity than asphalt. Light‑colored or white PVC sheets reflect significant sunlight, keeping the space underneath cooler. This is a major advantage for patios, carports, or buildings without insulation.
Winner for heat reflection and cooling: PVC roofing.
Asphalt shingles are relatively quiet during rain because the underlayment and decking absorb sound.
PVC roofing, especially when installed over open purlins (without a solid deck), can be noisier – you hear raindrops more clearly. However, you can reduce noise by installing PVC over a solid roof deck or adding foam underlayment. For covered patios, many people actually enjoy the sound of rain on PVC.
Winner for noise reduction: Asphalt shingles (unless you add decking under PVC).
Asphalt shingles are petroleum‑based and not easily recyclable. Most old shingles end up in landfills. They also require replacement every 15–25 years, creating ongoing waste.
PVC roofing sheets last 20–30+ years, meaning fewer replacements. At end of life, PVC can be recycled into new sheets or other products. Our manufacturing uses lead‑free stabilizers. The lightweight nature also reduces transport fuel consumption.
Winner for sustainability: PVC roofing.
Shingles are designed for steep‑slope residential roofs. PVC roofing is far more versatile:
Low‑slope or flat roofs – Shingles cannot be used below a 4:12 pitch. PVC works on any slope, including nearly flat.
Patios, pergolas, carports – Shingles are heavy and require a full roof deck; PVC is lightweight and can span open purlins.
Agricultural buildings – Shingles are vulnerable to ammonia from livestock; PVC is chemical‑resistant and easy to wash.
Greenhouses – Shingles block light; PVC can be clear or translucent for plant growth.
Coastal homes – PVC resists salt corrosion; shingles degrade faster.
For a traditional house roof with a steep slope, shingles are a proven choice. But for the applications listed above, PVC is clearly better.
Let’s summarize with a simple decision guide:
Choose asphalt shingles if:
You have a steep‑slope residential roof.
You want the classic, layered shingle aesthetic.
You are willing to replace the roof every 15–25 years.
Noise reduction is a high priority (or you have a solid roof deck).
Choose PVC roofing if:
Your roof has low slope (or any slope).
You want a 20–30+ year lifespan with minimal maintenance.
You need lightweight material (no structural reinforcement).
You are roofing a patio, carport, agricultural building, greenhouse, or coastal structure.
You want to reflect heat and keep the area underneath cooler.
You prefer an easy, DIY‑friendly installation.
For most applications outside of steep‑slope residential homes, yes – PVC roofing is better than shingles. It lasts longer, requires less maintenance, handles weather extremes better, is much lighter, and works on any roof slope. For a traditional house roof where the look of asphalt shingles is desired, shingles remain a good option. But for durability, versatility, and long‑term value, PVC roofing is the superior choice.
As a manufacturer of PVC roofing sheets, we have designed our product to excel where shingles fall short: low‑slope roofs, agricultural environments, coastal areas, and any structure where weight, maintenance, or longevity matters. Contact us to see if PVC roofing is right for your next project.
Can I install PVC roofing directly over shingles?
Yes, in many cases. Because PVC is very light, you can install purlins over existing shingles and attach PVC sheets. This avoids a full tear‑off. Check local building codes.
Is PVC roofing more expensive than shingles?
Material‑to‑material, PVC may have a higher upfront cost per square foot, but its longer lifespan and lower maintenance often make it cheaper over 30 years. (We do not list specific prices.)
Does PVC roofing look cheap?
Not at all. Modern PVC sheets come in attractive tile‑look profiles and matte finishes. From ground level, many people mistake them for clay or concrete tiles.
Can I walk on a PVC roof?
Only with crawl boards to spread weight. Regular foot traffic is not recommended. Shingles are more walkable but still require care.
Which is better for snow loads?
Both can handle snow, but PVC is lighter and less likely to crack from freeze‑thaw cycles. Thicker PVC (2.0–3.0 mm) is excellent for heavy snow regions.
