If you have a flat roof on your commercial or business building, then your roofing professional will need to inspect the roof at least once a year or so. This is necessary to make sure the roof is not leaking around any seams or penetrations. And, when it comes to penetrations, you can do some inspections yourself. Keep reading to learn about some signs that your penetrations need some maintenance. 

Torn or Ripping Boot

Most flat commercial membrane roofs will be fitted with installations like boots that fit around formations like plumbing vents. These boots are made from rubber and attach to the roof with the assistance of cement or another kind of adhesive. And, the boot itself can start to tear or crack due to the aging process. This is something that often happens to rubber over time due to general sun and weather damage. 

A torn or ripped boot is a sign that the boot needs to be replaced completely. While this may seem like an easy task, it is one that should be completed by your roofing professional. This way the membrane underneath can be inspected, as any opening in the roof is a weak area that is often prone to leaks. 

When the boot is replaced, ask about options that are more weather resistant like boots that are light-colored or ones that have thermoprotective coatings. Additionally, you want to make sure the right clamp or drawband is tightened over the open end. This will help to keep rain from seeping into and around the vent pipe.

Pulling Flashing

Flashing is another type of penetration that needs to be examined regularly, and this is especially true if you see the metal pulling up and away from the roof structure. This usually means that the adhesive or cement has started to deteriorate and the flashing has pulled up from it. Typically, the adhesive cracks and hardens over time and needs to be replaced. 

If your contractor needs to replace the adhesive tape or cement, then it is wise that the flashing be replaced as well. This helps to prevent water from pooling around seams and bends that develop when the flashing is pulled up and away from the roof. 

This same sort of process should also occur if there are any metal pitch pans on the roof. And, once the metallic pieces are replaced, you should watch to make sure that puddles are not forming around them when it rains. This means that the installations are angled correctly to allow for proper drainage. To learn more, reach out to local commercial roofing services.
