When it comes to investing in a metal roofing system, selecting the right paint coating is essential for both aesthetic appeal and long-term durability. At The Real Metal Roofing Company, we understand how important it is to protect your investment with the right warranty coverage. That’s why choosing between SMP (Silicone-Modified Polyester) and PVDF (Polyvinylidene Fluoride) coatings can be a crucial decision. In this comprehensive guide, we’ll dive deep into the differences between these two paint systems and their warranties, helping you make an informed choice.
What Are SMP and PVDF Paint Coatings?
Before understanding their warranties, let’s break down what SMP and PVDF coatings are and how they are used in metal roofing panels.
SMP (Silicone-Modified Polyester): SMP coatings are known for being a cost-effective, durable paint system commonly used in metal roofing. They provide decent protection against weathering, chalking, and fading but may not last as long as premium paint systems.
PVDF (Polyvinylidene Fluoride): PVDF coatings are considered top-of-the-line in the roofing industry. Known for their superior performance, especially in color retention and resistance to fading and chalking, PVDF is often used for high-end residential, commercial, and architectural projects.
Why Are Paint Warranties Important for Metal Roofing?
Whether you’re installing a metal roof for a commercial building or your home, paint warranties offer peace of mind that your roof’s aesthetic and structural integrity are protected over time. Paint warranties help ensure that the metal roofing colors stay vibrant and that the roof panels are protected from cracking, peeling, chalking, and fading.
At The Real Metal Roofing Company, we know how essential it is for homeowners, contractors, and architects to understand the warranties available with different paint coatings. Our goal is to educate you on the details so you can make the best decision for your metal roofing project.
Similarities Between SMP and PVDF Warranties
Both SMP and PVDF warranties offer protection, but how they differ in terms of coverage and longevity is key. Let’s first examine the similarities.
1. Film Adhesion Coverage: 40 Years
Both SMP and PVDF coatings provide a 40-year warranty for film adhesion. This means that, for four decades, the paint applied to your metal roofing panels is guaranteed not to crack, peel, or delaminate from the surface. This aspect of the warranty is crucial in ensuring that the metal underneath is adequately protected from the elements.
2. Chalking and Fading Coverage: 30 Years
When it comes to chalking and fading, both SMP and PVDF warranties typically cover these issues for up to 30 years. This coverage guarantees that the metal roofing colors will maintain their vibrancy and that chalking will not be excessive during this time.
Differences Between SMP and PVDF Warranties
Although there are some similarities in coverage, the key difference between these warranties is how SMP and PVDF coatings perform over time. Here’s what sets them apart:
1. Chalking and Fading Performance
SMP Coatings: SMP coatings are known to chalk and fade more quickly than PVDF coatings. As time progresses, metal roofs with SMP coatings may develop a white residue (chalking) and lose their original color (fading) at a faster rate. The fading performance of SMP coatings is typically measured in delta units, and higher values indicate more severe fading.
PVDF Coatings: PVDF coatings outperform SMP in both fading and chalking resistance. These coatings maintain the original metal roofing color for longer and experience less breakdown of the paint resin. PVDF coatings are often recommended for projects where aesthetics are a top priority.
2. Exclusions Based on Location
Both SMP and PVDF warranties contain exclusions, especially for areas exposed to harsh environmental conditions like saltwater. However, PVDF coatings have additional options for coastal areas:
SMP Coatings: Standard SMP warranties do not cover metal roofs installed within 1,500 feet of a saltwater coastline. Even if you’re using recommended materials like aluminum, the saltwater environment can severely impact the longevity of SMP coatings, voiding the warranty.
PVDF Coatings: PVDF coatings offer more flexibility for coastal installations. With a 35-year coastal warrantyfor aluminum roofing, PVDF-coated roofs are protected against chalking, fading, and film adhesion even in saltwater environments. For specialized locations like the Caribbean, custom 20-year warranties are available due to extreme weather and coastal conditions.

3. Material Types Covered by Warranties
Both SMP and PVDF warranties cover a variety of material types, including Galvalume, aluminum, and galvanized steel. At The Real Metal Roofing Company, we offer extensive options to meet your project’s needs, whether you’re working on a commercial structure or a residential property.
4. Impact of Color on Warranty Performance
It’s important to note that the color of your metal roof can affect how quickly it fades and chalks, regardless of the paint system. Darker colors such as reds and blues tend to show fading and chalking more noticeably than lighter shades like whites and grays. PVDF coatings, known for their superior color retention, are particularly beneficial if you’re opting for darker tones.
5. Weathering Factors and Location
As mentioned, environmental factors such as UV exposure, humidity, and proximity to saltwater play a significant role in how a roof’s paint coating weathers over time. SMP coatings are generally better suited for areas with milder climates, whereas PVDF coatings are ideal for extreme environments like those found near coastlines or in regions with high UV exposure.
Choosing Between SMP and PVDF Paint Warranties
To help you make the right choice between SMP and PVDF coatings, here are some critical factors to consider:
1. Cost Considerations
SMP coatings are typically more affordable, making them a great option for those working with a tighter budget. However, if you’re willing to invest more upfront, PVDF coatings offer better long-term performance and lower maintenance costs due to their superior durability.
2. Project Location
For projects located near coastlines or in areas exposed to high UV radiation, PVDF coatings are the best choice. The longer-lasting color retention and resistance to harsh environments make PVDF ideal for projects in these areas.
3. Aesthetic Preferences
If you want your metal roof to maintain its vibrant color for decades, PVDF is the way to go. It’s the premium choice for projects that require a balance of beauty and functionality. On the other hand, if your project doesn’t prioritize long-term color retention, SMP may be sufficient for your needs.
Tips for Understanding Paint Warranties
Navigating warranties for metal roofing panels can sometimes feel overwhelming. Here are some tips to make the process easier:
1. Read the Fine Print
Always take the time to read the entire warranty document, including the exclusions and limitations. Knowing what’s covered and what’s not will help prevent future surprises.
2. Talk to Your Roofing Supplier

Final Thoughts: The Best Warranty for Your Metal Roof
When choosing between SMP and PVDF paint coatings for your metal roof, consider both the short-term and long-term benefits. While SMP may be more budget-friendly, PVDF offers superior protection, especially in extreme environments or where color retention is a priority.
