Commercial Re-Roofing in Kenner, LA

The specific decision under International Building Code Chapter 15 Section 1512 about whether a new covering can be laid over an existing one (a recover) or the existing covering has to come off first (a replacement). The base rule and the three code prohibitions on a recover sit on the commercial roof replacement page. This page settles the second question: the membrane manufacturer system warranty on the finished roof.

The installer workmanship warranty is from the roofer and covers installation defects. The manufacturer system warranty is from the membrane maker and covers the finished roof as an assembly, subject to the specific terms and exclusions it names. They are separate documents with separate scopes and separate durations, and both are delivered at close-out.

Because the manufacturer is warranting a system that sits on top of an existing assembly it did not install. The condition of the existing covering, insulation and attachment is a source of risk the manufacturer cannot fully control on a recover, and the warranty terms it writes reflect that. On a tear-off with new insulation and a sound deck the manufacturer is warranting a system installed on a known base and can offer longer terms.

Yes, normally. A manufacturer system warranty on a commercial membrane is usually available only where the installing contractor holds an approved or certified installer status for that specific system. Approval is granted per system rather than blanket, so the scope names both the system and the roofer's approval on it before the scope is filed. This is why a specific membrane choice sometimes narrows the shortlist of contractors that can warrant it.

Common voids include unapproved repairs by a different contractor, foot traffic damage without a walkway pad system, missed periodic inspections, storm damage past the wind speed threshold the warranty names, and any deviation from the manufacturer approved installation instructions on the original installation. The specific list is on the warranty document and is worth reading in year one rather than in year fifteen.

Yes, under Louisiana R.S. 37:3737(I), and it is inspected against IBC Chapter 15. The Kenner Permitting Office at (504) 468-4062 option 1 handles it, Monday to Friday 8:30 AM to 4:30 PM. The application is emailed to kennerpermits@kenner.la.us or dropped off at 1926 18th Street. Kenner does not use MyGovernmentOnline; the MGO cities in this area are Metairie, Gretna, Harahan and Baton Rouge.

The City publishes "Cost varies" on kenner.la.us/249 against the permit fee for every project type on the schedule, so we do not invent a figure. The Permitting Office confirms it against the specific scope when the application is filed. We handle the intake and pass on what the department states.

The IBC Section 1512 code test and the manufacturer pre-installation inspection both run before the scope is filed. Where both permit a recover, the scope names a recover with the manufacturer's system warranty terms on it. Where either refuses a recover on the specific base, the scope is written as a tear-off. The two checks together settle it, not one on its own.

Not in a useful way. The manufacturer's eligibility criteria are system-specific, so a pre-installation inspection is against a specific membrane manufacturer's recover requirements rather than a general check. In practice, the survey narrows the membrane shortlist to one or two systems first, and the manufacturer inspection then runs against those specific systems.

Priced by area, assembly, insulation condition and whether the scope is a recover or a tear-off, not by a per foot figure that would mean anything on this page. The recover route is typically materially cheaper and faster than the tear-off route, and the warranty trade-off (shorter term, additional exclusions on a recover) is where the commercial arithmetic sits.
