Seam repair in Enigma

On any sheet system the seam is the weakest line on the roof, and the great majority of low-slope leaks start there rather than in the field. Seams fail from poor welding at installation, from thermal movement working them over years, and from standing water sitting on them continuously. Probing them is the single most useful diagnostic on a commercial roof — it finds failures that are not yet leaking and are far cheaper to address now.

What the job involves

  • Mechanical probe of every seam across the roof
  • Mapping of failed and marginal seams, not just the leaking one
  • Repair matched to the membrane system
  • Identification of the cause — welding, movement or ponding

Signs you need it

  • A leak that appears along a straight line rather than at a point
  • Visible gapping or lifting along a seam
  • Previous seam repairs that have not held

Why roofs fail in Enigma and Berrien County

Enigma sits far enough south to take the inland remnants of Gulf and Atlantic tropical systems, and on a low-slope roof that matters differently than it does on a pitched one. Sustained wind drives rain horizontally against upstands and parapets for hours, finding terminations and counter-flashing that shed vertical water perfectly well. The heat does the slower damage: roofs across Berrien County run hot for most of the year, which ages membrane, hardens seam adhesive and works every detail loose through thermal cycling. Then the humidity means that once water is inside the build-up it does not leave — saturated insulation in this climate stays saturated, quietly adding load and destroying thermal performance long before anyone reports a leak. That is why a moisture survey here tells you more about a roof's remaining life than its age does.

Enigma has a population of about 1,058, and the housing stock here sets the pattern for what fails first on a roof.

Questions about seam repair in Enigma

Why probe seams that are not leaking?

Because a marginal seam is an order of magnitude cheaper to fix than one that has let water into the insulation. Probing the whole roof costs a visit and tells you what the next two years look like, which is exactly the information a planned maintenance budget needs.

What causes seams to fail in the first place?

Most often under-welding at installation — a weld that held for five years but never had full strength. After that it is thermal movement at T-joints and changes in direction, and standing water sitting on a seam continuously.
