What is Causing My Commercial Roof to Leak?

Commercial roofing systems often differ greatly from residential roofs. Given this fact, the reason for leaks may differ also. Having your roof installed by licensed, knowledgeable professionals is key to ensuring that you have a quality product and quality workmanship. Many times the age of the roof is a factor in leaks. All roofs have a lifespan and if yours is nearing the end, it may begin to fail. Even newer roofs can experience leaks, leaving you to wonder why your newcommercial roof is leaking. Some of the most common causes of commercial roof leaks outside of aging include ponding, damaged membrane, drainage, improper sealing and damaged flashing.


Ponding occurs when areas of standing water pool on the roof’s surface. Because many commercial roofs are flat, this can be a common concern. Left untreated, this can lead to vegetation growth and structural damage. Keeping gutters and downspouts free of debris can help prevent water accumulation. Leaks from ponding can become severe and require immediate attention.

Damaged Membrane

Membranes are what make commercial roofs waterproof by securely sealing them. Membranes are exposed to the elements and consequently are subject to damage from the sun and other factors. You may notice holes or cracks. This allows water to seep in and damage the building’s insulation.

Improper Sealing

Proper sealing around air conditioning units, pipes, drains, vents, etc. is vital to the roof’s integrity. If not sealed properly, these areas can allow water to funnel inside your building.

Damaged Flashing

Flashing acts as a protection for the exterior edges of your roof and chimneys and vents as well. Weather and fluctuating temperatures can cause the metal flashing to contract, expand and loosen providing a way for water penetration.


Depending on location and weather, the typical commercial roof will last from 15-20 years. Inspections are important in helping you take the necessary steps to extend your roof’s lifespan and to know when the time has come for replacement.
