TPO Roof Membrane Installation Quality Control Checklist

Check that all the required equipment and materials for TPO roof membrane installation are available. This task ensures that the installation process can proceed smoothly without any delays. Are all the necessary tools and materials present? If not, what steps should be taken to obtain them in a timely manner?

Verify that the TPO membrane being used for installation is of the correct size, thickness, and color. This task ensures the installation meets the required specifications. Is the TPO membrane the correct size, thickness, and color? What action should be taken if any discrepancies are found?

Confirm that the rooftop is clean, dry, and free of any debris before installing the TPO membrane. This task ensures a clean surface for proper membrane adhesion. Is the rooftop clean, dry, and free of debris? How should any existing debris be removed?

Thoroughly inspect the rooftop for any sharp objects that could potentially puncture the TPO membrane. This task prevents damage to the membrane during installation. Are there any sharp objects on the rooftop that could pose a risk to the TPO membrane? How should any sharp objects be addressed?

Verify that existing insulation and cover boards on the rooftop are properly installed and secure. This task ensures a stable base for the TPO membrane installation. Are the existing insulation and cover boards properly installed and secure? If not, what corrective action should be taken?

Carefully examine the TPO membrane for any damages or defects before proceeding with the installation. This task ensures the membrane is in good condition and free from any issues. Is the TPO membrane free from damages and defects? If any damages are found, what steps should be taken?

Ensure that the TPO membrane sheets are properly aligned and overlapping according to the manufacturer's instructions. This task guarantees a watertight installation. Are the TPO membrane sheets aligned and overlapped correctly? If not, how should the alignment and overlapping be adjusted?

Validate that the seams of the TPO membrane are properly welded to create a strong and secure bond. This task guarantees the integrity of the membrane's seams. Are the seams of the TPO membrane properly welded? If not, what steps should be taken to correct the welding?

Use a seam probe to check the quality of the welded seam in the TPO membrane. This task ensures that the membrane has been properly welded and will provide a watertight seal. Does the welded seam pass the seam probe test? If not, what steps should be taken to address any issues?

Inspect the corners and edges of the TPO membrane to ensure they are properly fastened and secured to the roof. This task prevents any potential lifting or detachment of the membrane. Are the corners and edges of the TPO membrane correctly fastened? If not, what corrective action should be taken?

Verify that all required TPO accessories such as pipe boots, drains, or other penetrations are properly installed and integrated with the TPO membrane. This task ensures the integrity of the overall installation. Are all the required TPO accessories correctly installed? If not, what corrective action should be taken?

Ensure that flashings are suitably installed around any roof penetrations or edges to prevent water infiltration. This task safeguards against potential leaks. Are the flashings suitably installed? If not, what corrective action should be taken?

Conduct a water runoff test to confirm the appropriate installation of the TPO membrane and assess its water resistance. This task ensures that the membrane is properly installed and capable of withstanding water exposure. Was the water runoff test successful? If not, what corrective action should be taken?

Document the installation process, progress, and any issues encountered during the TPO roof membrane installation. This task provides a record of the installation and facilitates communication between team members. How should the installation process, progress, and issues be documented?

Review any concerns or issues raised by the Quality Assurance Manager regarding the TPO roof membrane installation. This task ensures that all concerns and issues are appropriately addressed and resolved. What is the concern or issue raised by the Quality Assurance Manager? How should it be resolved?

Verify the completion of the TPO roof membrane installation project and ensure the site has been properly cleaned and organized. This task confirms that the project is finished and ready for final evaluation. Is the project completed as per the requirements? Has the site been cleaned and organized?
