Is it Time to Replace Your Metal Roof?
When it comes to commercial roofing, metal is a superior material that can last upwards of 50 years. However, as your roof reaches the end of its life, you may notice a few signs of weakening or deterioration. Therefore, it is paramount you understand these signs, so you know when it is time for a repair or replacement.
1. Expansion
Metal naturally expands and contracts with the changing of the seasons. The movement in the panels causes a widening of the screw holes, but this can take decades to manifest. Although, when it starts, it is necessary to note that water can seep under the paneling to the decking below. Also, if holes get wide enough, you may lose panels during wind storms.
2. Buckling
Buckling is possible with aged and new metal commercial roofing. However, it likely only occurs because of improper installation or weather damage. Unfortunately, the only way to verify buckling is to have a rooftop inspection.
3. Weak Joints
Next, it might be time to replace your metal roof if you have noticed weak or degrading joints. After decades of weather exposure, you may find rusting, pitting or corrosion along joint lines. If you notice any issue with your roof joints, then a repair should be your immediate response, or you risk exposing and damaging the decking.
4. Water Logged Decking
If you observe waterlogged decking, then your commercial roof likely has any number of the above issues. Waterlogging increases the risk of mold and water spots inside the property. Therefore, when this type of problem is observed, it is a surefire sign that it is time to replace the roof.
Metal commercial roofing is a superior product, but while it does last nearly 50 years or more, it still requires maintenance, repair and eventual replacement. Hire a professional commercial roofer to inspect and assess your roof at the first sign of wear.
