We diagnose flat roof leaks by membrane type first, since a TPO seam fix and an EPDM patch use completely different materials and methods.

These are the specific reasons Prairie du Sac customers pick us for Flat Roof Repair work over a general handyman or an out-of-town crew.
Crews are trained separately on TPO heat-welding, EPDM adhesive seaming, and modified bitumen torch-down repair, since these systems aren't interchangeable.
Standing water after 48 hours signals a slope or drainage problem, not just a membrane issue, and we diagnose accordingly.
We coordinate repair timing with building management to avoid disrupting normal business operations.
We use water testing and seam inspection to confirm the actual leak source before cutting into a membrane, since flat roof leaks often travel before showing up inside.
Every category below is handled by our own Flat Roof Repair specialists, not a generalist crew or a subcontractor, which keeps the diagnosis and the fix consistent.
Heat-welded patches and seam repairs restore the membrane's watertight seal using the same welding method as original installation.
EPDM repairs use a liquid adhesive and seam tape system specific to rubber membrane, not a general-purpose sealant.
Repairing modified bitumen requires matching the original application method, torch or cold-process, for the patch to properly bond.
We address the underlying slope or drainage issue causing ponding, not just patch the membrane where it's currently failing.
Penetration points are the most common flat roof leak source, and repairs here get the same membrane-specific attention as field repairs.
Section replacement gets used when patching would leave a larger vulnerable area than a proper tie-in replacement.
