There are various factors that affect the lifespan of your roofing such as geography, climate, type of roof, and installation. Even the best roofing will eventually need replacement or renovation. This helps maintain the safety of the occupants and can help reduce energy use as well as prevent serious problems such as leaks. If you are considering renovating your commercial roofing, there are a few important things to keep in mind as you decide which solution is best for your roof.

Commercial Roof Renovation

  • Evaluate the roof: The current state of your roof is important. Do you need to completely tear off the roof or just place an overlay? If you are considering an overlay, the current roofing needs to be evaluated for damage before a new membrane can be placed. You also need to make sure your roofing structure can handle the additional weight of a new roofing membrane being placed on top. Roofing that already has significant structural damage will likely need total replacement, removing everything down to the deck. This is a more strenuous and expensive process, so make sure it is what you really need before getting started.
  • Inspect materials: The condition of the materials is important. You need to identify cracks, leaks, or torn membranes before renovating. You also need to check the condition of the drainage. Insulation can either be reused or recycled if it is polysio insulation. If the insulation is in good condition, you can re-use it, but this typically only works for recovering, as you will have to remove more insulation when doing a roof replacement.
  • Alternative materials: Roof coverings are convenient but they are not the only renovation option. One option is liquid-applied roofing that can extend the lifespan of your roof and reduce energy costs. To use this coating, the current roofing needs to be in good condition, so make sure any damage is repaired first.
  • Long term plans: Consider the use of the roof for the next 10 and 20 years. Is there going to be a lot of foot traffic? Are temperatures in the area high?The wear and tear the roof will endure will impact its longevity. Knowing this will help you decide which materials to use for the renovation. Reflective surfaces will be ideal for roofing exposed to a lot of sun and a vegetated roof is great for providing a relaxing, greenplace for occupants.
  • Don’t forget building codes: adhering to building codes is essential and this is the same for renovations. Codes and standards are always changing and may be different from the last time the roofing was repaired or renovated. Make sure you are up to date on all local codes and standards before starting a renovation project of any kind. You don’t want to spend time and money on work that is not permitted and will have to be taken down.
  • Inspect the roof regularly: You don’t want to wait to renovate the roof until damage has already occurred. Plan regular inspection at least twice a year so you can identify problems before they are serious. Renovations will be easier with minor repairs and can prevent you from having to do a full roof replacement. Not all problems can be easily seen, so regular inspection can catch issues before they cause damage.


Renovating your commercial roof is a great way to save energy and money, as well as extend the lifespan of your roof. With these considerations and the help of a professional and reputable roofer, you can make sure your commercial roof is strong, safe, and will last.
