What Are The Solutions for a Damaged Commercial Flat Roof?

A flat roof has different considerations than a sloped roof when you are trying to decide between roof repair or replacement. Repair is suitable for a small amount of damage, but the best solution for an old or heavily damaged flat roof is going to require a licensed commercial roofing services contractor who can evaluate the entire roof, including structural integrity, budget, and locale roofing ordinances. Based on the result of the inspection, one or more of these solutions will get your roof back into shape.


If the damage is minor and localized, you may be able to hire commercial roofing services to repair the roof. This option is usually less expensive than a full replacement, but it may not be a long-term solution if the damage is more extensive. Similarly, an older roof may not be suitable for a simple repair, and doing so may only delay the inevitable, requiring more costs in the future. Talk with your roofing contractor about the condition of your entire roof before you invest in minor repairs.


If your roof is still structurally sound but is showing signs of wear and tear, you may want to consider a roof restoration. This involves cleaning the roof and applying a new protective coating to extend its lifespan. This can include cleaning the roof, repairing any damage, resealing joints or seams, and adding a new layer of waterproofing material. Renovation is often a preferred way to extend the life of a flat roof that is showing signs of wear and tear, without completely replacing it. This is probably the most economical whole-roof solution, but it is only available in situations where the underlayment and structural support are sound. 


If your roof is outdated and not energy-efficient, you may want to consider a retrofit. A flat roof retrofit involves installing a new layer of roofing material over an existing flat roof. This is done to improve the performance and extend the lifespan of the roof without completely replacing it. The process may involve repairing any damages or leaks on the existing roof, adding insulation, and then adding a new layer of roofing material on top. Drainage is especially important with a flat roof, and any places where water is allowed to stand will increase the chances of developing a roof leak and deterioration of the roof sheeting and trusses. 


If the damage is too extensive, or if your roof is approaching the end of its lifespan, you may need to replace the roof entirely. A flat roof replacement involves completely removing the old roof and replacing it with a new one. This may be necessary when the existing roof is beyond repair or has reached the end of its lifespan. During a replacement, the entire roof structure may be inspected, and any underlying issues or damages may be addressed before a new roof is installed. This option can be expensive, but it will provide a long-term solution and potentially increase your property’s value. Replacement can be more expensive than renovation, but it may be necessary if the existing roof is beyond repair or if a new roof is needed to meet building codes or regulations.

Repair or Replace?

It’s important to consult with a professional roofing contractor to determine the best course of action for your damaged commercial flat roof. They can assess the extent of the damage and provide recommendations based on your budget and needs. Your commercial roofing services contractor can break down the actual results of the inspection, which will include things such as these:

  • Age of the Roof – If your flat roof is old and has reached the end of its lifespan, it may be more cost-effective to replace the roof rather than continually repairing it. Replacement is also necessary for situations where the structural support has been damaged, usually caused by a serious or long-term leak allowing water to penetrate the interior of the home.
  • Extent of Damage – If the damage to your flat roof is minor and localized, it may be possible to repair it. However, if the damage is extensive or covers a large area, a replacement may be necessary. For example, it makes sense to repair a corner that was damaged by a falling tree, but if the damage includes a quarter of the roof surface or more it is probably a better idea to replace the whole thing.
  • Type of Material – Different types of flat roofing materials have varying lifespans and durability. Some materials may need to be replaced sooner than others, even with regular maintenance and repairs. In this situation, you may want to consider a new roof using different materials. This option has the potential to lower your energy bills as well since it implies using newer insulation.
  • Cost – Depending on the extent of the damage and the age of the roof, it may be more cost-effective to repair the roof rather than replace it. However, if the repairs are frequent and ongoing, it may be more cost-effective in the long run to replace the roof. Trying to nurse an older roof along for a few years is likely to have increasing repair costs with each patching up, plus the growing risk of damage inside the home.
  • Future Plans – If you plan on selling your property in the near future, replacing the roof may be a better option, as a new roof can add value to your property and make it more attractive to potential buyers.

The available options for correcting a flat roof requires a thorough assessment of the roof’s condition, the cost of repairs versus replacement, and your future plans for the property. It may be helpful to consult with a roofing professional to help you make an informed decision. If you decide that roof replacement is your best option, you will also have the option of choosing a different roof type, alternative roofing materials, and more. You also have the option of installing one with a slope that eliminates the vulnerabilities of a flat roof.
