During the manufacturing process, the metal panels are galvanized in a molten zinc bath, painted, and finished with a Kynar 500 or PVDF 70 coating. The Policyholder thought that the roofing manufacturer might have been Taylor Metal Products (also located in Salem). From phone and email correspondence with Taylor Metal, they stated that the roofing looked like it was from Bruce & Dana. Upon corresponding with Bruce & Dana, they confirmed that it was their product. This was based on them seeing 20 photos of the panels; each manufacturer has slight but recognizable adjustments to the profile of the section, with curvature of the ribs varying slightly between Taylor Metal and Bruce & Dana panels. Mark Pallas of Bruce & Dana Wholesale Inc., the manufacturer of this roof, stated that "the roof looks really good," especially for its age, and is "not compromised." He said that if it were affected by heat, then we would see blistering of the paint. And, he said that weathering is normal and oxidation is common. People may think that the paint is the issue, but it's "just oxidation." Some think that metal roofs are maintenance free, however they do require periodic maintenance. Their recommendation for maintenance and to remove oxidation is to use one cup of Tide laundry detergent to 5 gallons of water, make a couple of passes with an RV cleaning brush on a pole, and rinse it off. Mr. Pallas noted that if paint were to have blistered off due to heat, the underlying galvanization is fused to the metal base and would continue to resist corrosion. Regarding screws that have loosened or are missing, Mr. Pallas stated that due to expansion and contraction of the metal roofing and screws due to temperature changes, normal wood fasteners will back out. About 10 years ago they changed their screw specification to a different type, with anti-backup threads.
