For most people, their commercial / industrial flat or low slope roof is “out of sight, out of mind” and only comes to the forefront when it begins to leak. It’s at this point where Bel-Con are often called in to investigate the cause. If the leak is minor, irregular or relatively new, we are looking for a method to repair the roof. If the leak is major, constant or ongoing, we are tasked with looking for longer term solutions including possibly re-roofing the facility.
In order to determine a course of action, we start by visiting your site and conducting a review of the facility. Our review is more than simply having a look at your roof. It also includes the following:
There are many types of industrial, commercial and institutional roofing, but the main systems are asphalt/tar and gravel, single ply membranes including PVC and EPDM both ballasted and fully adhered, modified bitumen and metal systems (both through-fastened and standing seam). Where applicable, our inspection looks at the following for each of the above noted roof systems:
The above items are examined in combination with the knowledge gained in the interior inspection of the facility to determine the cause of the roof issue(s). At this point, we establish a plan to implement the required repairs or, in more extreme cases, a replacement plan is formed. The further along in the life cycle of your roof, the more likely multiple factors could be the cause. The older your roof the more likely a roof replacement is going to be the best and, in some cases, only solution.
Generally speaking, most leaks are the result of one or more of these factors:
One of the things we often see is the use of the wrong materials to make a repair, resulting in a short term fix but compounding the problem for the future. To avoid this, the key factor (whether it be annual maintenance, finding the cause of a leak and/or repairing a leak) is to have this done by a person familiar with the roof system. This person will know how your facility’s roof should be detailed and how it should be maintained; in other words contact a professional!
We’re always happy to help. Please get in touch if you would like us to perform an inspection of your building’s roof. Our service area is GTA to Kingston, north through to Peterborough.
