What are the causes of commercial roof leaks?
Sure, it is a great responsibility to own and maintain a commercial roof. When the commercial roof starts to leak, it can be really hectic and stressful. The problem starts to become even more frustrating when you don’t know why and how the leaking started. However, knowing the reason for leakage is the first way to get rid of the leak.
Some of the causes of commercial roof leaks are:
If there is no way for your flat roof to drain properly and the drainage system is not fixed in time, then the days to look roof like a swimming pool is not far away. Ponding water can be the most common cause of commercial roof leakage or water damage. The roof leaks can add significant stress to the roofing system as one square foot of ponding water weighs around 5 pounds per inch of water.
Property owners must ensure that water flows correctly and freely of the roof between drains, scuppers, gutters, and downspouts of a flat roof. However, in some of the case, the existing drainage system may not channel water adequately, which entail commercial repairs to the roof.
Open Roof penetration
Penetrations are tubes, drains, and other items that perforate the surface of a building. All roof penetrations are susceptible to leaks and have to be adequately safeguarded to protect the roofing system from water damage.
Roof penetrations may include HVAC systems, drains, winds, ducts, tubes, gas lines, hot stacks or other items routed through the roofing membrane. To ensure that they are kept watertight with lighting, field covers, rain collars, tube shoes, or pitch pans, it is a good idea to observe every roof penetration closely.
Roofing Membrane Damage
The material may break, blister, crack, shrink or puncture as the roofing membrane gets old, giving way to the water to the roof under the membrane. The primary function of the roof membrane is to prevent water from entering the interior of the building, making the membrane avoid commercial leakage of the roof.
If the roof membrane on your commercial roofing is clearly not in good condition, we strongly recommend contacting an immediate roofing professional to help prevent more water damage. If the issue is looked upon in time, it is often possible for roofing contractors to conduct small roof repairs rather than a full-scale replacement.
Aging of Roof System
After a period of time, the commercial roofing system starts to degenerate beyond the point of repair. Upon installation, most flat roofing systems start to deteriorate rapidly after 15-20 years, though this may rely on the roofing material used in the house. At this stage, it may be in the best interest of a property manager to schedule a commercial roof repair to fix the entire roofing system.
Last but not least, the elements are exposed continuously in an extreme weather condition. Across gutters and drains, ice and snow may build-up, leading to water ponding into the roof. Violent hurricanes or tornados may demolish a roof in a single blast in some parts of the country. But, more generally, the slow, steady fall of rain, ice, and hail over time has a cumulative impact on roof leakage. The sun beats almost every day on the roof, and high speeds storms will snap tree branches, limbs, and other objects which causes all roofing content to be weakened.
