Thermoplastic Polyolefin (TPO) is a popular roofing option, particularly among building owners. It offers several advantages that makes it well-received among roofing contractors and customers alike.
TPO is a single-ply membrane that offers high reflectivity. It is mechanically attached or adhered to the roof decking for maximum weather protection. Customers appreciate its energy efficiency as well as its relatively low cost and its durability. TPO is known for its resistance to ultraviolet (UV) rays, algae, dirt, bacteria and debris. A good TPO roofing system can last a long time, thanks to its capacity for resisting impact, tears and punctures.
To enjoy its full benefits, you should keep your TPO roofing system as clean as possible. Keeping your TPO clean:
- Allows it to reflect as much light as possible, adding to its energy efficiency,
- Helps prevent the growth of bacteria and algae, which can thrive on dirt and debris,
- Removes possible sources of food for birds and other pests, and
- Gets rid of chemicals that might reduce the service life of the TPO or affect its performance.
To keep your TPO clean, here are some tips:
- Keep Unauthorized Personnel Off the Roof
- Untrained personnel can damage your TPO roof. Allow access only to trained professionals that know how to avoid damaging the membrane.
- Enforce Safety Personnel allowed to clean and maintain your TPO roof should follow fall safety requirements. They should wear the right boots, which reduce the possibility of slip and fall accidents, particularly if the roofing system is wet. Only allow access to a wet roof if absolutely necessary. Harnesses may also be needed.
- Never Walk on a TPO Roof With Cleaning Solution Personnel should only be allowed to walk on the TPO roofing system if the cleaning solution has been rinsed. It’s advisable to limit foot traffic if the membrane is still wet.
- Protect Exterior Facades Cleaning personnel should test a small area of the facade with cleaning solution to ensure the solution doesn’t affect it. At any rate, it’s best to keep the solution away from other surfaces.
- Comply With the Law Some local, federal or state laws have strict regulations regarding the handling of cleaning solution run-off. Make sure your cleaners comply with those regulations. Whether there are laws or not, keep the solution away from plants and prevent it from contaminating groundwater.
