Signs you need to plan for roof replacement

Every commercial property manager needs to be concerned about the condition of their roof.

A flat roof is particularly vulnerable to moisture and other damage caused by rough weather. Here are some of the signs, both hidden and obvious, that a flat roof is due for repair or replacement.

Outdoor Damage

Annual inspections will help alert you to developing roof problems, such as cracks or mold. The metal strips known as flashing must remain sealed to protect against debris and water getting into your roofing system. Even if the metal is only slightly bent, it can compromise your roof and allow water to seep through. It’s best to have your flat roof checked after a heavy rain, to make sure the storm hasn’t caused cracks in the roof or drain clogging.

Indoor Indicators of Problems

Evidence that a flat roof has been compromised is the appearance of interior water stains. These water stains may appear on the ceiling or walls on an upper floor. A major red flag that water has penetrated below the surface of your flat roof is when mold and mildew are accompanied by foul odors. If left untreated, major deterioration can occur to the roof, requiring a complete replacement.

As a property manager, you risk finances spiraling out of control if you avoid scheduling annual roof inspections. Simply by checking the condition of your flat roof each year will prevent small leaks from turning into big fiascos, such as a roofing overhaul. 


It’s hard work keeping track of everything a commercial property needs over the years. But the fact of maintenance is that if the roof needs work, there’s more to follow if it’s ignored. Metal roofing is low maintenance and does well against the New York elements. However, it still receives wear and tear over the years and will need to be replaced eventually. Keep an eye out for the following signs that the metal roof needs to be replaced.

Sign 1: Rusting

The biggest problem metal roofs will have as they age is that they may rust. When you see large patches taking over, the protective coating on the metal is deteriorating. That can lead to cracks, holes, and leaks within the building. You can often repair small parts, but when the problem spreads, it’s better to replace the roof.

Sign 2: Leaks

Rust isn’t the only thing that can allow a metal roof to leak. Panels could become loose and allow water through the openings. There can also be mold growth or structural damage from a storm. Have the roof inspected regularly to avoid these issues, but if you see leaks forming, it’s probably best to replace the roof.

Sign 3: Deteriorating Metal

High winds can also have an effect on the metal in the roofing material. If you notice the metal deteriorating in any way and it has been decades since the roof has been replaced, it’s probably best to move forward with a replacement.

Replacing a roof can be expensive and while metal roofing can last for 50-60 years, it will come to the end of its life at some point. As the property manager, the best thing you can do for the roof is to have it inspected on a regular basis, so you can fix small issues and avoid the complete replacement as long as possible. You can also keep an eye on the above signs to know when replacement time is approaching. If you don’t replace the roof at the right time, larger issues like water damage and structural problems can occur.
