Commercial roofing systems are designed for durability and high-efficiency, but as is the case with any roof, nature can wreak havoc on a roof over time.
Hail, strong winds, rain, salt, and UV rays can result in a leaky commercial roof over time.
Standing water is one of the biggest factors leading to commercial roofing leaks. Any number of things can cause water to collect on the rooftop, including poor/clogged drainage, bad roof installation/design, debris on the roof (leaves, tree limbs, etc.), and more. Catching the problem early can save the roof from time-consuming, expensive roof repairs or replacement down the road.
Aside from weather-degradation, commercial roof repairs are also necessary in cases where the original roof wasn’t installed correctly and isn’t functioning as it should be.
Signs of a poorly installed roof include:
- Bubbling/blistering on the roof surface
- Uneven surface
- Poor water shedding/drainage
- Poor interior insulation
Hiring a licensed, experienced commercial roofing contractor to inspect and make repairs is the best way to maximize the life of a commercial roof.
Property owners and facility managers who routinely inspect and repair their roofs before problems occur spend an average of 14 cents per square foot compared to 25 cents per square foot for owners that take a reactive approach.
Taking a proactive approach—as opposed to treating problems after they arise—increases the average lifespan of your commercial roof up to 21 years.
Commercial roofs are not meant to be the “set it and forget it” type of roofing systems—they require regular maintenance. Many commercial roofing contractors offer inexpensive commercial maintenance plans that will take care of all the roof maintenance required to keep your roof in tip-top shape.
If you choose to handle the roof maintenance yourself, make a habit of inspecting the rooftop at least once a year.
How to maintain a roof and minimize damage:
The first thing to do is clear the roof of leaves, fallen tree limbs, and other debris. Next, scrub the roof clean of bird droppings, moss and algae, salt (if near the ocean). and staining caused by berries or oils. Then, use a mild detergent specially formulated for use on commercial roofing.

For a very minor leak repair, it could cost as little as a few hundred dollars. However, major repairs can run upwards of several thousand dollars.
The cost of a commercial roof repair can vary significantly based on...
- the extent of the damage
- the size of the roof
- the roofing material used
- your geographic location
- the contractor you hire
For instance, one business owner needed a minor leak sealed up on his commercial building located in California. It cost just $300 to have the verified commercial roofer come out and waterproof the roof. Another business owner from Illinois had a more extensive and more costly commercial roof repair. This fix required mulitple leak repairs and a new aluminum coating on the roof surface to reflect the sun’s UV rays. This repair ended up costing $7,000.
One reason it’s not a good idea to repair commercial roof damage yourself (or let the “weekend” roofer down the road help you) is the seemingly endless number of building codes you must adhere to when doing any sort of commercial roof installation or repair.
Local and state governments adopt rules and regulations to ensure the community’s health and public safety. In other words, to prevent the roof from collapsing on you a week after you install it.
These commercial roofing building codes can be a pain to sort through, which is why it’s a job best left to the professionals. This is yet another reason why it’s important to choose a roofing contractor based on the company’s experience handling commercial roofing projects rather than just residential roofing.
It’s sometimes difficult to find a reputable, experienced commercial roofing contractor since many roofing companies focus solely on residential roofing.
