These field examples show why a metal roof leak should be traced to a specific joint or penetration. A short video demonstrates the method, but preparation and cure time still depend on the actual roof.

What to check first

  • Separate screw leaks from seam leaks.
  • Look for movement or rust before covering a joint.
  • Use the video as a demonstration, not a promise of a ten-minute repair.

Prepare the joint before sealing it

  1. Check movement and support

    Loose fasteners, separating joints, and deteriorated metal need attention before a liquid repair. Sealant is not a replacement for missing support or a failed attachment.

  2. Identify the bonding surface

    Determine whether you are bonding to bare metal, a factory finish, or an older coating. Remove loose rust and failing material as directed; leave a sound, clean, fully dry surface.

  3. Follow one compatible repair system

    For suitable Turbo Poly Seal seam repairs, embed the specified fleece in the wet base coat and saturate it with the top coat. Screw-head details may use sealant without fleece. Follow the current detail rather than mixing instructions from different products.

Watch the field examples

These archive demonstrations show individual projects. Use the current guidance above and Bergstrom’s published instructions if an older video shows a different product or method. Torch work shown in installation videos is professional work.
