Galvalume panel manufacturers offer material warranties covering coating integrity and substrate perforation. Warranty terms range from 25 to 40 years depending on coating thickness and panel profile. These warranties cover manufacturing defects and premature coating failure.
On the galvalume systems we install in Pinecrest, that coverage carries specific names. The McElroy Metal Galvalume Limited Warranty covers the AZ-55 substrate against perforation, the McElroy Metal Kynar 500 PVDF warranty covers the factory finish against fade, chalk, and peel, and the Sheffield Metals 40-Year Limited COOLR paint warranty applies when the system is specified with the AZ50 substrate option. Our own workmanship warranty covers the installation itself, so the coverage reads as workmanship plus substrate plus color rather than a single manufacturer line.
Workmanship warranties cover installation quality. Our workmanship warranty on galvalume installations runs concurrently with the manufacturer's material warranty, so you have coverage for both the panels and the installation through the warranty period.
Warranty claims require documentation. We photograph the roof deck, underlayment, galvalume panel installation, and flashing details during construction. This documentation supports warranty claims if issues arise and verifies that installation met manufacturer specifications.
We hold certifications from metal roofing manufacturers including PAC-CLAD, Englert, and Berridge. These certifications confirm that our installation methods meet manufacturer standards and that material warranties remain valid.
Warranty exclusions typically include damage from foot traffic, hail, windborne debris, and alterations made by others. Warranties also exclude corrosion caused by contact with incompatible metals or exposure to corrosive chemicals. Review the specific warranty document for your galvalume system to understand coverage limits.
