It is no surprise that machine-welded seams hold the advantage over hand-welded seams, removing the risk of fish mouths and creating a stronger seal between pieces of cover sheet.

See our crews in action as they apply the cover sheet to a newly applied commercial roof in Denver, CO.  We removed an old, leaky 3 ply Built Up Roof (BUR) weighted down with gravel ballast.  We replaced it with a properly draining TPO roof over new ISO insulation and solid Densdeck.
If you have questions or concerns about your commercial flat roof (Gravel ballast, TPO, EPDM or PVC), call today for a no-obligation inspection and commercial roof report.  Cenco is open every day, and we can always be reached at (720)-583-1690.
