Can TPO be installed over my metal roof?

Sometimes, for qualifying roofs. A TPO retrofit is a project-designed assembly. Existing structure, attachment, moisture, drainage, wind requirements, applicable code, and manufacturer criteria must be reviewed. Existing silicone does not by itself establish eligibility or ineligibility.

Roof Hugger is designed structural subframing that supports a new metal roof over a qualifying existing metal roof. It is distinct from coating and TPO retrofit. We evaluate the existing structure and system design; we do not promise universal no-tear-off or zero disruption.

The Right Approach

Low-slope commercial roofs require careful attention to seams, flashings, drains, curbs, and membrane condition. We investigate visible leak indicators and roof failure points to help identify the most likely source before recommending a repair.

What This Work Involves

Low-slope commercial roofs require attention to seams, flashings, drains, curbs, terminations, membrane condition, roof traffic, punctures, and ponding water.

TPO and PVC work uses compatible membrane details and heat-welded repairs where appropriate. EPDM uses its specified compatible repair materials. We do not describe all single-ply systems as repaired identically.

For qualifying roofs, a TPO retrofit over an existing metal roof is an available option: fitted flute-fill insulation between metal ribs, the specified insulation/cover-board assembly, and a new TPO membrane with heat-welded seams.

Document Your Roof Before Deciding

We evaluate the roof first, then recommend repair, restoration, coating, maintenance, or replacement planning based on actual condition — not a predetermined sale.
