Painted coil carries two warranties from the mill and the paint maker: one for the finish and one for the metal underneath. Here’s how they work and what to do when you need one.
Our Kynar 500 coil
Our Kynar 500 (PVDF) coil uses Sherwin-Williams Fluropon paint and carries a 40-year finish warranty. The metal substrate carries a 25-year warranty. The exact terms are in the warranty document for the product you buy. Ask for it with your order.
What a finish warranty covers
Finish warranties usually cover:
- Chalking beyond the limit set in the warranty.
- Color change (fading) beyond the limit set in the warranty.
- Peeling, cracking or flaking of the paint film.
The limits are measured with standard tests, and they differ between paint systems and colors.
What a substrate warranty covers
A substrate warranty covers the metal itself, usually against perforation by corrosion under normal weather. It does not cover cosmetic marks or rust that starts at damage.
What they usually don’t cover
- Installation errors and poor details.
- Scratches and dents from handling, foot traffic or tools.
- Contact with incompatible metals, treated lumber, or runoff from copper.
- Standing water, debris or corrosive fumes.
- Coastal exposure the warranty excludes. Steel close to salt water is often limited.
Read the document before you bid a coastal or industrial job.
Weathertightness warranties
A weathertightness warranty covers leaks in the installed roof system. It comes from the panel system maker and the installer, not from the coil, and it is usually priced per project. If your project specifies one, ask us before you bid.
Register a roof
Register the finish warranty with the coil tag number, the install date and the job address on the finish warranty registration form. Keep the invoice, coil tags and photos in the job file.
Damaged or incorrect material
Material that arrives damaged or wrong is not a warranty claim. Report it within 30 days of receiving it on the damaged material claim form.
