How Do You Repair A TPO Roof?
A TPO roof generally has a lifespan of 15-20 years, yet during this period, it can experience issues such as seam failures, flashing problems, and membrane punctures. These issues often lead to water infiltration, which is commonly the first sign of trouble. Water entry usually results from adhesive failures at the seams, allowing moisture to accumulate in the TPO insulation and eventually seep into the roofing deck. Once water begins to leak into the building’s interior, prompt action is necessary to prevent further damage. Engaging a professional roofing contractor for a thorough inspection and repair at the earliest sign of leakage is crucial to protecting the roof and building structure.
A skilled contractor’s inspection will assess the roof’s overall condition and identify specific areas of concern. The contractor will evaluate the source of water infiltration, the extent of dampness within the insulation, the age of the TPO roof, and the number of roofing layers, as well as assess the state of the seams. Infrared inspections are a vital tool for this process, especially when conducted approximately 30 minutes after sunset, allowing the roof to cool while waterlogged insulation retains heat. Using an infrared camera, contractors can identify temperature differences that signal damp areas, marking these spots for repair. This targeted approach ensures a comprehensive understanding of roof damage, enabling precise repairs and extending the roof’s service life.
Repair Options For TPO Roofs With Less Than 25% Saturation
After a thorough infrared survey confirming that the TPO roof has minimal saturation, a silicone restoration membrane system can be a viable solution for roofs with less than 25% saturation. This approach provides a proactive, efficient way to repair and extend the life of the roof. The process begins with detailed surface preparation to ensure the silicone coating adheres properly and offers maximum durability. Contractors will remove and replace saturated areas with matching materials, followed by a comprehensive power wash of the entire roof surface. This ensures a clean foundation, allowing for the TPO roof seams to be reinforced, enhancing both strength and resilience. Once the roof is prepared, a uniform layer of silicone coating is applied, sealing the roof against further damage and providing long-lasting protection.
However, in cases where the TPO roof has less than 25% saturation but the seams are severely damaged, a silicone restoration may not be feasible. In this situation, covering the TPO with a board, cutting off flashings, and opting for a spray foam roofing system becomes a practical solution. Spray foam roofing not only seals seams but also provides excellent insulation and durability. This approach is more economical than a full tear-off and replacement while still addressing the roof’s needs effectively.
Repair Options For TPO Roof With >25% Saturation
Following a comprehensive infrared inspection, it became clear that the roof’s TPO insulation and membrane have reached high levels of saturation, making restoration impossible. In this scenario, the only viable option is a complete tear-off to expose the roof base by removing all TPO and soaked insulation. Once this process is complete, a new thermoplastic polyolefin (TPO) roofing system can be installed. Given the history of issues with the current TPO setup, considering an alternative roofing solution may be more cost-effective. Spray foam roofing presents an attractive option, especially for its insulation advantages, durability, and seamless application, which can address typical roofing challenges more efficiently than a traditional TPO membrane.
Spray foam roofing stands out for its superior insulation properties, offering the highest R-value per inch among roofing systems. This high R-value enhances thermal performance, helping to significantly lower energy costs and improving indoor comfort by maintaining consistent temperatures. Spray foam’s sustainability is another advantage; recoating the roof every 10-20 years allows for an affordable warranty extension without requiring a full roof replacement. Additionally, spray foam’s seamless application effectively prevents leaks at seams, a common issue in layered roofing systems. For roofs that need TPO removal, contractors can install a cover board before applying spray foam, which ensures robust insulation and a longer-lasting, energy-efficient roof.
