Prevent Oil Canning in Your Kenmore Home’s Metal Roofing

oil canning kenmoreHave you noticed how some metal roof panels appear to bulge or have waves in them? This is known as oil canning, and it creates a look that’s unprofessional. All metal panels, including zinc, aluminum and copper panels, are vulnerable to this.

What Causes Oil Canning?

These bulges and waves can be caused during the manufacturing process. While being flattened, rollers with gaps in them distribute pressure unevenly, producing panels which aren’t perfectly formed.

Oil canning may also be caused by other factors, such as thermal expansion, improper storage, incorrect installation, or shifting of the beams and other support structures.

Can it Be Prevented?

Prevention is up to the manufacturer and installer. There is really nothing the homeowner can do. This is why it’s important to hire a reputable roofing contractor that, in turn, hires reputable sub-contractors. It’s also important to verify that the contractor has purchased his material from reputable manufacturers.

The best answer is to replace the panel which has been oil canned, although it can sometimes be repaired. Adjusting the internal supports to place additional tension on the outward side of the panel may solve the problem. A contractor can examine the roof and make a determination regarding repairs or replacement. More often, the latter is in order.
