Commercial Roof Replacement

Things to Consider for Commercial Roof Replacement

Commercial roof replacement is intended to protect the building as well as the lives of the workers within. However, you need to consider the condition of the roof and check for damaged areas in order to differentiate between a repair or a replacement. 

A commercial roof replacement can solve many problems. Here are a few things to consider if this is right for you: 

  • Cost-Effectiveness
  • Condition
  • Lifespan
  • Leaks
  • Season
  • Project turnaround time

Cost-Effectiveness:  If your roof has a minor defect, you can avoid a total commercial roof replacement by pursuing the proper repairs and saving the cost. 

Condition: If your roof is getting old but you notice that it is still structurally sound and can withstand the coming years, you can have an inspection to determine any potential repairs and retain its longevity. 

Lifespan: The lifespan of your roofing can provide you with the information you need to determine how much more time you have before needing a roof replacement.

In addition to several roof material options, you can also consider coating the roof every 10 years to maintain its condition. Materials that provide longevity include metal, EPDM, TPO, and modified bitumen.

Leaks: If you are experiencing any leaks, you need to conduct a proper inspection of the roof. Leaks can appear anywhere and are usually difficult to spot without professional help. You may also be unaware of the extent of a leak as it can be anywhere from a few drops to a whole stream. It is important to identify and repair leaks in a timely manner to avoid a total roof replacement.

Season: If you are thinking of having a replacement, you need to consider having the replacement during the summer to allow time for the roof to properly dry.  

Project turnaround time: An overall roof replacement may take more time than you would expect, as each piece will need to be replaced. We encourage you to refrain from installing the new roof on top of the old one as this can lead to unexpected issues. 

For commercial roofing systems, the contractors typically use products that can be easily applied over the roof’s surface. Commercial roof replacement may include both the roof and its coating. If you opt for a watertight spray coating, you can extend the life of your roof for 10 years.

Tips to Know If you Need New Commercial Roofing

Here are a few tips that can help determine a commercial roof replacement service.

Leak History

Keeping track of leak history can tell you whether you want a full commercial roof replacement or just a repair. You will first need to inspect yourself to ensure that the membrane surface of the roof is in good shape. This membrane can be damaged by trapped moisture. 

Our inspection process involves taking samples to understand what type of material is being used and how many layers your roof has. Finding any moisture inside the insulation of the roof will dictate the roof replacement.

Roof Membrane

You need to look for the signs of the roof membrane being lifted by the wind in problem areas including corners, seams, and parapets.

If you are unaware of the special uplift code factors for your building, you can call our inspection experts to assist you and provide an uplift wind test.

Roof Deck

Significant damage to a roof deck can lead to an additional replacement. Moisture can pile up in the roofing compartment under the deck, allowing mold to develop and spread. Over time, such mold can eat away at the roof.

Roof Warranty

If your roof is still under warranty, you may be eligible for a partial replacement of your roof. If you have visible damage, the roofing companies may pay for any repairs under the warranty. However, if you don’t consult such a company then you might have violated the warranty.

Roof Coating

Electing for a roof coating can provide a number of advantages, including:

  • Minimal repairs
  • Adding a sleek touch
  • Reflecting heat and UV rays 
  • Protecting against leakage
  • Extending roof lifespan

If you currently have a roof coating, you might need to replace it to ensure the roof and your home is protected for years to come.

You may also want to consider the roofing company that provided you with its service. If you chose a cheap company, you might end up replacing the whole roof due to the use of the wrong roofing material or other applications during installation that unintentionally compromised the roof. 

Other Signs that you need to Consider

  • Roof Age (roof age is generally between 25 to 30 years)
  • Curling, splitting, and other deformities to the roofing material
  • Leaks, soft spots, or wet insulation
  • Visible scrim reinforcement
  • Rotting flashing
  • High granule loss
  • Sunlight coming through the membrane or anywhere else


A commercial roof replacement is a big investment, so it is important to consider the points we outlined above before pursuing such a project. 

If you have trouble conducting the inspection yourself, our professionals can help guide you in detail and will distinguish between needing a roofing replacement or a repair. For services in California, visit our friends at  Roofing Contractors Citrus Heights.
