3 Signs Your Commercial Building's Flat Roof Is Deteriorating
If the building in which you conduct your business has an old flat roof, you may wonder if it is still in good condition. If so, look for the following three signs that your commercial building's flat roof is starting to deteriorate and needs professional attention.
Large Pools of Water
When you first go up on the roof to inspect it for damage, the first sign you may see that indicates your roof is damaged is pools of water. When checking for standing water, do your examination shortly after it rains so you can see the extent of the problem.
If the tar coating has started to become uneven, water will start to collect in these areas. Also, if the damage has gone unnoticed for a while, the water may have leaked into the underlayment of the roof, making it sag in areas where water pools may be found.
Rips in the Tar Coating
Another sign that your old flat roof should be inspected by a professional roofer is the presence of rips or holes in the tar coating. This coating is made from the same material as asphalt roads. On a flat roof, it is used as a protective layer that keeps water from leaking into the building.
If the coating becomes damaged, the roof is in danger of leaking in the near future. Depending on the number of rips and holes, a roofer may be able to patch the areas. However, if rips are found on a majority of the roof, it may need to be replaced.
Curling at the Seams
While looking at any rips in the roof, look carefully along the seams of your building's flat roof. Normally, the seams should fit tightly next to each other and lay flat against the roof's surface.
Over time, however, exposure to the sun and temperature changes may make the asphalt material from which the roof is coated shrink. When this happens, the seams may start to curl up, leaving the area beneath them exposed to water. Eventually, these openings will lead to leaks in your roof.
If you see any or all of the signs above, the roof on your business's building may either need to be repaired or replaced. Contact a commercial roofing company like JC Roofing & Insulating to schedule an inspection so they can examine the damage and discuss your options for fixing any issues before the roof starts to leak.
