At Metal & Roof Production, we believe in helping consumers make informed decisions. A metal roof is a long-term investment, and the paint system plays a major role in how that roof looks and performs over the decades. Two finishes dominate the industry: Kynar® (PVDF) and SMP (Silicone‑Modified Polyester). They’re both solid options, but they’re not built the same.
Kynar (PVDF): The Premium Standard
If you want the best of the best, Kynar is the top-tier
finish. It’s engineered for long-term color performance, UV resistance, and
overall durability. This is the coating we recommend when customers want their
roof to look just as good in year 30 as it did on day one.
Why Kynar Stands Out:
Unmatched fade resistance: dark colors stay dark / bright colors stay bright.
- Superior chalk resistance: Kynar resists the white, powdery aging you see on lower-grade finishes.
- Long-term gloss retention: panels keep their original sheen instead of dulling out.
- Built for harsh environments: high heat, intense sun, coastal air — Kynar handles it all.
- Industry-leading warranties: many manufacturers back Kynar with 30–40 year paint warranties.
This is the finish we trust for high-end homes, commercial
buildings, and any project where long-term aesthetics matter.
Silicone‑Modified Polyester Painted Metal (SMP): Reliable, Durable, and Budget-Friendly
SMP coatings blend polyester with silicone to create a tough, cost-effective finish. It’s a great option for consumers who want the durability of metal roofing without the premium price tag of Kynar.
Where SMP Performs Well:
- More affordable upfront: a smart choice for budget-conscious projects.
- Hard, scratch-resistant surface: holds up well during transport and installation.
- Wide color selection: plenty of modern, attractive colors available.
- Solid performance in moderate climates
SMP does well in areas without extreme UV exposure.
SMP is a dependable finish; it just ages faster than Kynar, especially in darker colors.
Side-by-Side Comparison
Color Performance:
- If long-term color consistency is a priority, Kynar is the clear winner.
Longevity:
- Kynar: 40+ years of color performance often with manufacturer warranties for color fade.
- SMP: 20–30 years depending on climate and color.
Cost:
- Kynar: Higher upfront investment
- SMP: More budget-friendly
We often tell customers: If you’re planning to stay in the home long-term, Kynar pays for itself.
Kynar is ideal for:
- High-end residential roofing
- Commercial buildings
- Coastal or high-UV environments
- Dark or saturated colors
- Projects where appearance matters long-term
SMP is ideal for:
- Standard residential homes
- Agricultural buildings
- Light commercial projects
- Budget-driven installs
- Lighter colors that naturally fade less
Our Recommendation
At Metal & Roof Production, LLC, we install both systems — because both have their place. The right choice depends on your priorities:
- Want the longest-lasting color and finish? Go with Kynar.
- Need a durable metal roof at a lower price point? SMP is a strong, dependable option.
- Building in a high-sun or coastal area? Kynar is worth the upgrade.
- Choosing a lighter color in a mild climate? SMP performs very well.
No matter the finish you choose, you’re still getting the strength, longevity, and value of a metal roof and that’s a win. Call us with any questions or for a quote: 972-354-6102.
A note: In certain markets, metal can still be found using polyester paint. We do not recommend this metal in the southern markets because the fading and chalking is extremely quick and not worth the price difference.
