There is no doubt about it. Your roofing takes quite a beating, but that’s its job. Your commercial or industrial roof gets the blunt end of all kinds of weather. Hail beats on it, ice and snow deposits rest on it, high winds want to rip it off, and the sun’s unforgiving heat rains down on it. Your roof should withstand all these elements and more, like that giant tree branch that just fell on it.
We are used to our roofs doing their job silently, so we don’t pay too much attention to them. We only realize something’s off when it suddenly starts leaking and entire ceiling sections are soaked. However, you don’t have to wait for that to happen to tell if there’s a problem with your roof. Follow these simple steps from PRC Roofing Company and you’ll spot a problem with your roof miles away. The biggest advantage of catching a problem early on is that you get to fix it before it becomes expensive and has your tenants complaining.
We’ll focus on the most common commercial roofing solution, the Built-Up Roofs (BUR). These roofs are made by combining several layers of bitumen and asphalt. Gravel is used on the surface of the roof, and the quality of the gravel determines the reflectivity of the roof. We’ll look more into that later.
Leaks and Moisture Buildups
Leaks are almost certainly a sign of trouble. There are several reasons why leaks develop on BUR. For instance, there might be a problem with the flashing detail because they were either not fastened down properly during installation. In fact, 95% of all leaks, PRC Roofing fixes on BUR start at the flashing joint. Therefore, always inspect the flashing detail and anywhere the membrane of the roof gets interrupted for signs of trouble.
You may also have the same problem if you have a single-ply membrane roof, another common commercial roofing option. If the seam work on the roof was done haphazardly, the membranes cannot hold water. The family-owned company uses heated glue to hold the seams back together more securely.
Tenting and Billowing
Improperly installed flashing also causes tenting and billowing in bituminous roofs. If the flashing is poorly attached, the seams may come apart causing tenting, reducing the roof’s wind resistance. The same problem may be caused by improperly embedded gravel on hot bituminous roofs.
The same problem is common in single-ply roofs. If the seams are not adhered properly, they come apart and consequently stand a risk of blowing off, or billowing. The first sign of danger here is manifest in the form of open seams where the flashing begins, as illustrated in many of the projects completed at commercialroofinghoustontx.com.
This sort of problem is easy to fix when caught early. The flashing section can be properly secured or the seams of a single-ply roof can be sealed properly with adhesive. During the repair, the cold adhesive used on roofs must be left to cure properly before adding the gravel substrate.
