Commercial roofs are designed for durability and longevity. That doesn't mean they're designed to last forever. Over time, your commercial roof can deteriorate. If you're like most commercial building owners, you don't get up on the roof as often as you should. An annual roof inspection will help you catch the problems you need to address. That way, you can take care of roof repairs before you need to pay for a replacement. If you're not sure what to look for when inspecting your commercial roof, read the list below.
Here are four signs that your commercial roof needs repairs right away.
Blistering
Blistering is a serious problem for flat or asphalt shingle roofs. Blistering occurs when moisture or air gets trapped under the roofing material. Once air or moisture gets trapped, blisters or bubbles appear in the roofing material. Without repairs, blistering can cause the roofing material to separate from the underlayment. That's why you should get your commercial roof repaired at the first sign of blistering.
Sagging
When you're inspecting your commercial roof, be sure to walk the entire surface. You want to feel the roofing material under your feet. You might not know it, but you can tell a lot about the roof by the way it feels under your feet. During the inspection, you'll want to check for sagging. If your roof is sagging, it will feel uneven under your feet. You can also identify sagging by checking for pooled water. If the roof feels uneven, or you see pooled water, call for commercial repairs right away. Without repairs, the roof could collapse.
Spongy
Sagging isn't the only thing you want to check for when walking around your commercial roof. You also want to check for sponginess. Your commercial roof should feel firm under your feet. Firmness is a sign that your roof is structurally sound. If areas of your commercial roof feel spongy under your feet, call a commercial roofing company immediately. Sponginess is a sign that the underlayment is damaged. You'll need to have that repaired as soon as possible.
Leaking
Leaks are another problem you need to worry about when you own a commercial building. Water stains and puddles are two signs you need to watch for. If you see either of those signs, you need to call for repairs. If you don't see water stains or poodles, you should inspect the attic. That's especially important after heavy rainfall. If you see leaks or moisture in the attic space of your commercial building, you need to get your roof repaired immediately.
