Can You Restore Your Aging TPO Roofing System with a Silicone Roof Coating?
If you have an aging TPO roof, but it is still structurally sound, you may be able to avoid a full replacement. A silicone roof coating provides an affordable, dependable solution to restore your TPO roof‘s performance and extend its life and energy efficiency without the disruption of a full roof replacement.
Considerations for Coating Over an Existing TPO Roof System
Before applying a rooftop coating, it is necessary to evaluate the existing TPO roof membrane for moisture, damage, and overall structural integrity. If the roofing system is dry and is completely down flat with no major deterioration, it is typically a good candidate for silicone restoration.
Surface Preparation and Cleaning
Thoroughly cleaning the surface is very important. Dirt, debris, and built-up oil must be removed from the surface to ensure proper adhesion of the silicone coating. Most often, this requires surface power washing, then waiting for itto dry out before applying each silicone coating. Any punctures, splits, and seam issues must be repaired before proceeding to apply the coating.
Primer Compatibility with TPO
Because TPO roof membranes are slick, they usually require a specialty primer to adhere silicone coatings properly. Failing to apply a compatible primer could lead to peeling or poor adhesion of the silicone coating. Always apply a primer that the manufacturer of silicone coating recommends specifically for TPO.
Benefits of Coating Over Existing TPO Roofs
Coating over an existing TPO roof will save you money, time and labor compared to tearing off the existing roof and replacing it. You will also eliminate the need for landfill disposal of the existing roof and minimize disruption to your business. Additionally, the seamless layer of silicone will significantly enhance the waterproofing, reflectivity, and UV resistance of the roof without replacing the entire roof.
Cost and Time Savings with Restoration Rather Than Replacement
The typical silicone restoration project will cost only a small fraction of the cost of a total roof replacement. Further, silicone restorations can generally be completed in less time with fewer workers. There will be no tear-off of the existing roof, no debris disposal needed, and very little interference with your building operations, making this one of the most efficient ways to restore a roof.
Final Thoughts on TPO Roofing Silicone Coating Restoration
Silicone coatings can be applied to existing TPO roofs as long as the existing roof is in good condition and is properly prepared. Silicone coatings offer a cost-effective, sustainable way to restore your TPO roof system and extend its useful life.
