Unfortunately, leaks in commercial and industrial flat roofs are inevitable. However, with the causes in mind, repair and replacement costs can be minimized if preventative measures are taken and maintenance is carried out regularly.
What Are the Causes of Roof Leaks?
This is the number one cause of leaks in flat roofs in commercial and industrial buildings. Since the roof is flat, water does not drain as easily as it would on a sloped roof. Once water collects on a flat roof there is more chance that it will find entranceways into the roofing system and cause a leak.
The Solution: The best way to fix this problem is to make sure the roof system is water tight and there are adequate drainage routes, which brings us to the next point.
Clogged Drainage Routes
Drains can get stopped up with inadequately removed debris left over from construction or leaves and branches. These blockages prevent the water from escaping properly and allow the water to find cracks and holes to enter.
The Solution: Regular flat roof maintenance needs to be carried out seasonally to check and empty drains for good water flow.
Extreme Weather Fluctuations
Rapid changes in temperature can cause the roof to first expand in the heat and contract with the cold. These movements in the roof can cause elements in the roof system to crack, separate and become loose.
The Solution: While you cannot prevent the weather, reflective coating on the commercial or industrial flat roof can help minimize the effect of temperature changes. This is done by keeping the temperature of the roof more consistent and avoids extreme fluctuation.
