Indications that a commercial roof replacement may be in your future include leaks around roof vents and fixtures. Good preventive repair work can extend your roof a little while longer, but a roof replacement is still coming. Here are some of the leaky indicators, their repairs, and what happens to a roof if leaks are left unattended.
The Flashing Needs Replacing
Flashing is the material used to seal a barrier around any structures rising from a roof. In commercial roofing, there are often circulation vents and box controls for heating, cooling, refrigeration (if applicable), and electrical systems around which the flashing has to be secured. If leaks are coming from these areas, the roofing contractor just needs to peel back the already loose flashing and see what kind of damage he/she is looking at. If the water damage is extremely minimal, then the roofer only has to replace and secure all of the flashing. If you ignore the problems with flashing and leaks, the water gets deep inside the layers of the roof and causes extensive damage.
The Drains May Be Clogged
Most commercial roofs are flat--sort of. They may slope gently this way or that to help guide rainwater off of the roof. The water ends up down a roof drain or channeled into a gutter/downspout system. If any of these features are clogged with leaves or some sort of debris, the contractor only has to clear the drains, gutters, and/or downspouts. Once these features have been cleared, the contractor will check and test everything to make sure the water is no longer looking for a downward path to follow (i.e., leaking through the building's roof/ceiling). If there is still some dripping and seeping, the contractor will look at the areas where the water seems to be coming in in order to find the cause and replace part or all of the roof.
There May Be Standing And Pooling Water On A Flat Surface
Water always looks for a way to drip down. It works with gravity, not against it. Hence, a pool of standing water on your roof will look for a way to drip, and if that way is through an open area in the roof, that is the way the water will go. The contractor has to look at where the water is pooling and then follow that to where the leak exists inside. Opening up this area will reveal the extent of the damage and the need for a partial or complete roof replacement.
