If you own or lease a commercial building with a flat roof, It’s never a good sign if you suspect leakage. Does this mean your entire roof needs to be replaced? No. There are various options to consider before a full roof replacement is even necessary. If you notice a leak in your roof, the first thing you should do is call A Plus Roofing Co. We have the tools to diagnose leaks repair your roof where necessary.
Many Problems Can Cause Leaks on a Flat Commercial Roof
Flat commercial roofs are immensely complex. Seams in a roof can crisscross large expanses and are sometimes created to poke through the roof. Any number of issues can arise in an otherwise serviceable roof. The expert inspectors at A Plus Roofing Co. will look first for these common issues:
● HVAC Penetrations and Pipes: Oftentimes, HVAC systems rest on curbs that can be easily be sealed, however, corner seams can sometimes come loose. A cavity filled with tar or other poured sealing substance make the areas where the wires and hoses penetrate the roof watertight. These sealants shrink over time, allowing water to run into the building along the wires and hoses. Plumbing pipes often have boots with neoprene gaskets that wear out faster than the rest of the roof.
● Broken Field Seams: If your roof was properly installed, the field seams should have held for the roof’s intended lifespan, however, weather damage, excessive foot traffic, or possible disruption in the installation process could have weakened the roof and seams.
● Cracks in Tar: Built-up roofs (BURs) can dry and shrink as the years wear on. Fine cracks can develop in the tar and grow larger until they eventually channel water into the building.
● Cuts in the Membrane: Something as small as a boot with a pebble stuck in the tread can puncture a thinner, more economical roof membrane. Tools dropped by repair technicians can do the same. That's why A Plus Roofing Co. repair crews take extra precautions to prevent such damage.
Sometimes It's Not the Roof
Stucco parapet walls can develop cracks and allow leaks that aren’t from the roof itself. The sealant in skylight assemblies can also dry out and separate from the curbs or panels. While any water coming in from above seems to be a "roof" leak, sometimes the leak isn't from the roof at all. That’s why it’s incredibly important to have a professional accurately trace leaks.
