GAF TPO Roof Membrane Installation Quality Control Checklist

Check that the roof surface is free from debris, dirt, and any moisture that could affect the installation of the TPO membrane. A clean, smooth, and dry surface will ensure optimal adhesion and performance of the roof system. Are there any visible signs of dirt, debris, or moisture on the roof surface?

Ensure that all necessary tools and equipment are available for the installation process. Having the right tools will enable the workers to perform the installation efficiently and accurately. Are all the required tools and equipment readily available for use?

Ensure that the TPO membrane is aligned correctly and without any visible wrinkles or unevenness. Proper alignment and smooth surface of the membrane are crucial for achieving a high-quality installation. Is the TPO membrane aligned correctly and free from wrinkles?

Thoroughly inspect the edges of the TPO membrane for any damages, defects, or imperfections that may affect the overall integrity and performance of the roof system. Are there any visible damages or defects on the edges of the TPO membrane?

Ensure that the appropriate measures for wind uplift resistance are observed during the installation process. Proper wind uplift resistance measures will enhance the durability and longevity of the roof system. Have the appropriate measures for wind uplift resistance been observed during the installation process?

Verify that the seams of the TPO membrane are correctly hot-air welded. Proper welding of the seams ensures strong and secure connections between membrane sections, preventing water leakage. Are the membrane seams correctly hot-air welded?

Confirm that all flashings and accessories associated with the TPO membrane installation are properly installed. This includes edge flashings, pipe boots, roof drains, and any other required components. Have all flashings and accessories been properly installed?

Perform a thorough inspection of all membrane seams using a seam probe. This will help identify any weak spots or inconsistencies in the seam welding. Are there any visible issues or inconsistencies found during the seam probe inspection?

Perform a water tightness test on the installed roof system to ensure that there are no leaks or water infiltration. Is the roof system water tight after the water tightness test?

Ensure that the manufacturer's recommended maintenance protocols for the TPO roof system are clearly communicated to the client or building owner. Clear communication of maintenance protocols will help extend the lifespan and performance of the roof system. Have the manufacturer's recommended maintenance protocols been communicated to the client or building owner?

Thoroughly document all observations and findings during the quality control inspection process. Proper documentation will serve as a reference for future reference and aid in resolving any potential issues or disputes. Have all observations and findings been properly documented?

Take pictures of the fully installed and completed roof system from multiple angles. These pictures will serve as visual evidence of the quality of the installation and can be used for documentation and future reference. Have pictures of the finished roof system been taken?

Ensure compliance with all applicable safety regulations and proper disposal methods for any waste or hazardous materials generated during the installation process. Compliance with safety and disposal regulations is essential for maintaining a safe and environmentally friendly work environment. Are all safety and disposal regulations being complied with?

Develop a plan for the proper removal and recycling of any material wastes generated during the installation process. Proper waste management and recycling practices contribute to environmental sustainability. Has a plan been developed for the removal and recycling of material wastes?

Submit a final roof installation report summarizing all the quality control inspection findings and observations. The report should provide an overview of the installation process, highlight any issues or areas of concern, and recommend any necessary follow-up actions. Has the final roof installation report been submitted?
