Free Roof Inspections in Amarillo, TX
Authorised applicator status is the prerequisite for No Dollar Limit warranty coverage.
| EPDM — thermoset | TPO — thermoplastic | |
|---|---|---|
| Response to heat | Cured — does not re-soften | Re-softens, allowing fusion |
| Seaming method | Adhesive seam tape with primer | Hot-air welded |
| Seam strength source | Adhesive bond between sheets | Fused polymer — one continuous mass |
| Repair method | Clean, prime, patch with tape or adhesive | Weld a patch directly |
| Field verification | Visual and probe inspection of tape laps | Probe testing of every weld |
| Weather sensitivity at install | Higher — surfaces must be clean and dry | Lower — welder compensates for conditions |
Because EPDM cannot be welded, its seams depend on adhesive bond rather than fusion. That places EPDM’s principal risk at the seam and makes surface preparation the governing quality variable, where TPO’s governing variable is welder calibration. Both systems fail at seams. They fail for different reasons and are controlled by different disciplines.
Baseline resistance. Adequate in low-exposure regions with minimal rooftop traffic. Marginal against Texas Panhandle hail.
Velzen standard specification for Amarillo, TX. Materially higher puncture resistance than 45-mil at modest additional cost.
Highest available. Best performance under hail, heavy service traffic, and equipment maintenance. Suited to dense rooftop HVAC, industrial roofs, and high-value long-hold assets.
Where three sheets converge, the step created by the underlying lap prevents a continuous bond. Every T-joint receives a pre-formed patch over the intersection. Unpatched T-joints are a recurring source of leaks on EPDM roofs.
Completed seams are probed along their length and inspected for edge lift, fishmouths, and voids. Defects identified at installation are repaired at no cost; the same defect found in year three costs a section.
EPDM seaming requires clean, dry surfaces and appropriate ambient temperature for primer flash-off. Amarillo's wind carries dust onto prepared lap areas, and work stops rather than proceeding onto a contaminated surface.
Terminations at parapets, curbs, and penetrations use termination bars, pre-formed corners, and lap sealant. Detail work carries the movement and the water, and is where EPDM roofs leak — the field membrane rarely fails first.
