How a repair visit works

A Pasadena roof repair, from gate to closeout.

On an industrial site in Pasadena, a roof repair starts before the crew reaches the roof: site orientation, the work permit, and the access route. Mammoth Services confirms those with your safety contact when you call, so the visit is not held up at the gate.

On the roof, the crew follows the water back to its source and checks the membrane around it. On PVC roofs that means testing whether the sheet is still flexible and weldable. Active leaks are sealed first, then the permanent repair is welded or installed and photographed.

If the roof needs a replacement or a membrane change instead, see industrial and commercial roofing in Pasadena.

PVC repair

Repairing PVC and PVC-KEE roofs.

PVC is often chosen for roofs exposed to grease and oils. Repairing it well depends on the condition of the sheet.

Weldability test

Weathered PVC is cleaned and test-welded. If it welds, it can be patched. If it will not, the area gets new membrane.

Plasticizer loss

GAF notes greases and oils can draw plasticizers out of PVC, causing hardening and embrittlement. Brittle areas crack and are replaced, not coated over.

Matched material

Repairs use compatible PVC or PVC-KEE membrane and flashing, heat-welded to the existing sheet.

Exhaust and grease areas

Areas around exhaust fans, grease traps, vents, and stacks repaired and, where needed, protected with a sacrificial layer.

Seams and flashings

Open seams re-welded and probed, and wall, curb, and pipe flashings rebuilt.

Find the source

GAF says chemical exposure on a roof can be a sign of a broader problem. Mammoth Services reports the source so your team can address it.

Wind across the Ship Channel.

Public storm data around Pasadena shows strong gusts on open industrial ground and heavy rain.

Ike, 2008

The National Hurricane Center lists an 80-knot (about 92 mph) gust at Hobby Airport, a few miles west of Pasadena.

Permits and site rules

Which rules apply to a Pasadena repair.

Where the building sits decides the paperwork.

01

Inside city limits

The City’s fee schedule says roof repairs or replacement over 25 percent of each roof require permits. Mammoth Services measures the repair scope against that line and confirms with the Permit Department when it is close.

02

Industrial districts

The City says industrial districts in its extraterritorial jurisdiction are not subject to City ordinances and permitting requirements. The site’s work permits, hot work rules, and roof access procedures govern instead.

03

East of SH 146

Inside Pasadena city limits east of SH 146, TDI’s windstorm program applies, and TDI says roof repairs there must be built and inspected to TDI specifications for TWIA eligibility.

Questions

Roof repair in Pasadena: direct answers.

If your question is not here, call Mammoth Services at (832) 416-1566.

  • 01

    Can a weathered PVC roof still be repaired?

    Often yes, if the membrane is still flexible and the seams can be cleaned and welded. Where grease, oils, or chemicals have drawn plasticizers out and made the sheet brittle, patches will not hold, and that area needs new membrane. Mammoth Services test-welds the sheet before recommending a repair.

  • 02

    Does a roof repair in Pasadena need a City permit?

    Inside city limits, the City’s fee schedule says roof repairs or replacement over 25 percent of each roof require permits. Industrial districts in the City’s extraterritorial jurisdiction are not subject to City permitting, but the site’s own work permits apply.

  • 03

    Will our warranty cover chemical damage?

    Usually not. GAF says manufacturer warranties typically exclude damage caused by oils, greases, and chemicals. That is why Mammoth Services looks for the exposure source during the repair and reports it to you.

  • 04

    Does the TDI windstorm program apply to a Pasadena roof repair?

    Only in part of Pasadena. TDI includes the areas inside Pasadena city limits and east of State Highway 146 in its Harris County catastrophe area, and says roof repairs there must be built and inspected to TDI specifications for TWIA eligibility. West of SH 146 the TDI program does not apply, though City permit rules still do. Mammoth Services checks which side of the line your building sits on.
