While metal roofs can last anywhere from 40 to 70 years, they typically show signs that they need to be replaced when they get near the end of their lifespan. If your commercial roof in the Andersonville neighborhood of Chicago is made of metal and has been in place for decades, you’ll want to keep an eye out for the following signs that it needs to be replaced:
Expanding Screw Holes
When a metal roof is held in place by screws, the screw holes gradually expand as the metal expands and contracts. Expanded screw holes can cause two major problems: (1) they allow water to work its way underneath the metal, causing serious water damage to the decking; and (2) once the holes are wider than the screw heads, they can cause metal panelling to shift or fall off of a roof. Most metal roofs will only experience these types of problems if they are decades old. However, as they enter the final quarter of their lifespan, having them inspected for expanded screw holes could prevent extensive roof damage down the line.
Metal panels can buckle for one of two reasons — they may have been incorrectly installed, or they may have taken on severe weather damage. In either case, an Andersonville roof replacement company is the recommended solution. In some cases, a commercial roofing company in Andersonville, Chicago can detect metal panels buckling by examining them from the ground. However, a rooftop inspection should still be carried out to determine the extent of the problem.
Joints in Bad Condition
The joints of a roof typically receive more weather exposure than its other parts. Consequently, they are often the first components to show signs of weather damage. Pitting, rusting, and corrosion along joint lines are three common signs that the joints are in poor condition. The primary risk of damaged joints is water damage to the decking — a problem that could significantly increase the cost of a roof replacement in Andersonville, Chicago.
Waterlogged decking is usually a symptom of other problems, particularly the ones above. Once a roof deck becomes saturated with moisture, it is only a matter of time before the signs of a water-damaged roof (such as mold and water spots on ceilings) are seen on the inside of a building. Because water can seep through even the smallest openings, having a roof inspected for damaged decking annually is a smart idea.
Andersonville Roofing Company Repair or Replacement
Understandably, most commercial building owners would rather have their roof repaired than replaced — and in many cases, damaged commercial roofing needs a repair or restoration, not a replacement. However, there are some cases when repairing a metal roof could cost more than replacing it. In these situations, it makes sense to replace the roof altogether.
If you suspect that your building’s roof needs a replacement, addressing the problem now could minimize the replacement cost, and it can also prevent your building from experiencing other problems like ceiling damage and mold growth.
