Do PVC Commercial Roofs Need to be Cleaned?

Have you thought about cleaning your PVC commercial roof? Many business owners may not be thinking about the need to do so, but having it done could provide some benefits. Yet, there are some risks to cleaning this structure. If not done properly, it can cause damage to the roof, and that can lead to costly problems later. The key here is to know when to do it and how to do it properly if you do need to clean the structure. 

Cleaning Commercial roofs is part of commercial roof maintenance. Many of the chemicals and techniques used should only be done by professionals or building managers that have extensive experience with maintaining commercial roofs. Many of these chemicals and techniques if not executed by someone very familiar with them could do more damage than roof preservation. 

When Should PVC Roofs Be Cleaned?

It is important to know what the manufacturer recommends. Some companies may not encourage the cleaning of the roof structure, while others may state it is beneficial to do so. 

It is beneficial to clean your PVC roof after a storm or any other time when there is debris on it. This could be a part of your routine maintenance. Removing debris, especially tree branches and leaves, helps to minimize the risk to the structure. 

If your roof is susceptible to environmental damage, contaminants, or dust and dirt, it may be beneficial to clean the roof using the recommended cleaning agents. You may also need to have the roof cleaned more often in these situations. 

Some systems are designed to minimize the need for frequent cleaning. They may have a membrane on them that helps the roof to remain cleaner for a longer period of time. Even in these situations, though, the roof could get dirty, and that takes away from the overall look of the building. Key concerns are typically organic material from trees, dirt, and dust. If you hope to ensure the roof looks good and lasts the longest, cleaning the roof can be beneficial. 

How Often Should PVC Roofs Be Cleaned?

As noted, it is important to know what your manufacturer recommends in terms of cleaning the PVC commercial roof membrane. Most of the time, it’s best to clean it by following these tips:

  • If there’s been a significant storm or other type of event that caused debris or other material to land on the roof, prioritize cleaning it.
  • Consider cleaning it annually if it is in a typical area. If there is a high risk area where environmental debris is more significant, do so more often. 
  • If the structure becomes noticeably dirty, it may be necessary to clean it at that time as well. 

There are benefits to cleaning the roof on a consistent basis. It can extend the life of the roof and helps to keep the roof the most reflective it can be. That, in turn, helps your organization to conserve energy and keep temperatures inside more controlled. Also, cleaning it can help to reduce algae growth and keeps pests away from the structure. 

How Are PVC Roofs Cleaned?

It is best to have a professional crew work to clean the PVC roof. There are many reasons for this. First, these surfaces are very dangerous, especially when they are wet. It is not safe for anyone to clean the structure unless they are able to have proper harnesses and equipment to minimize the risk of falling.

Also, teams have to pay close attention to how they are cleaning the roof. Using any type of high pressure can create a significant amount of damage to the structure, which is difficult to fix and can lead to structural damage to the roof itself.

It’s also important for teams to avoid walking on cleansing solutions and to properly remove them if they are used so that the chemicals do not damage the roof surface. The type of chemicals used should be specifically considered acceptable according to the manufacturer’s recommendations. 

It is also beneficial for professionals who know and understand these roofing systems to handle the cleaning of them. That is because they can pinpoint any areas of concern quickly and minimize risks of damage to the structure. Without a doubt, there are tricky areas here, including along the exterior façade and flashings, that need professional care.

Tips and Tricks for Extending the Life of Your PVC Roof

There are a few things that owners can do to extend the life of their PVC roof. Being particularly careful about the roof structure could help you to keep more money in the bank. Some key ways to improve outcomes include:

  • Removing dirt and debris as soon as possible. If there are trees in the area, keep branches trimmed away from the structure.
  • Avoid walking on the structure. The more people walk on it, the higher the risk is for damage to occur. 
  • If it is washed, use only the proper materials. That includes a low PSI power wash as well as water. When possible, minimize the use of chemicals. If they have to be used, be sure to rinse them thoroughly off the structure to reduce risk.
  • Pay attention to algae and mold growth. If this develops, be sure it is cleaned properly to remove these materials. There are cleaning solutions that can help, but you should not use chemicals that are more intense as that can damage the structure.
  • Always have an annual inspection of your roof. This is the best way to pinpoint areas of concern and to have them treated quickly and effectively. A professional can also provide advice and guidance on the benefits of cleaning the surface.

PVC roofs are just like any other roof. A bit of close attention may help to extend their lifespan and minimize the need for costly repairs during their lifetime. For a business owner, keeping these surfaces clean and in good condition does not have to take much. Having a trusted company that can handle and specializes in PVC roofing is one of the best ways to reduce those risks.

Take the time to turn to a local professional who can provide a comprehensive inspection of your existing structure to determine what steps are needed to maintain it to the best level possible.
