Metal roofing has a stellar reputation for providing adequate protection and doing so for a really long time. Nevertheless, metal roofing does deteriorate, it does break down, and it does sustain damage. Therefore, this form of roofing may very well be in need of repair at some point. If you are on the search for a new home, the roof is one of the most pertinent points of the house to pay attention to. You are going to want to know if the roof is in need of repair before you make an offer. Here are a few ways to spot a metal roof that is in need of professional repair.
The fastener points appear to be wallowing out.
You won't see fasteners on all types of metal roofing, but they can be visible on some of the more traditional roofing panels. If a panel sustains blunt force or is picked up by the wind, it is the area around the fastener that usually sustains damage. The rest of the panel may look fine, but you will see some wallowing out or welling at the fastener point. Likewise, if the standing seams of roofing panels have dents and dings, it is a good sign the roof may need some level of repair. These issues can often lead to leaks and further deterioration of the full roofing system on a home.
The painted finish of the roof is starting to wear away.
While many assume the painted finish on a metal roof is purely for cosmetic value, the finish can actually protect the underlying metal from the elements. If you are looking at a home and see the paint is starting to wear away, it is a good idea to get a new home roofing inspection once the home becomes yours. The roof may need to be refinished with a protective coating.
The edges of the roof appear to be breaking down.
If possible, get a good look at the thin edges of the roofing panels. When panels of a metal roof start to wear down, the damage usually shows up along the edges first. While worn or deteriorated edges may be concerning, the damage may not always mean the entire roof has to be replaced. It is relatively common for certain panels to break down if something is wrong with the gutter system or water is not draining away from some points of the roof properly.
