Does the City of Garland require permits for commercial flat-roof replacement?
Yes. The City of Garland Development Services Department requires a commercial roofing permit for replacement projects, and the permit process verifies compliance with the Texas building codes adopted by the city. Projects involving structural alterations, changes in fire-resistance assembly, or addition of significant mechanical equipment require plan review before permit issuance. Your contractor should pull the permit and maintain the inspection record — do not authorize a commercial re-roof that begins without a permit number confirmed.
How do I assess whether an existing Garland commercial flat roof can be recovered or must be fully torn off?
Texas building code, like most building codes referencing the IBC, generally allows one recovery layer over an existing membrane provided the existing assembly is dry and structurally sound. A core test — typically punching several plugs through the membrane to evaluate insulation condition — is the standard diagnostic. Wet insulation must be removed regardless of layer count. A recovery that traps wet insulation beneath a new membrane will fail prematurely and void the new membrane's warranty.
What warranty documentation should a Garland commercial property owner receive after a flat-roof installation?
You should receive two distinct warranty documents: the membrane manufacturer's system warranty, which covers both the material and — critically — the installation if it was performed by a factory-authorized contractor, and the installer's separate workmanship warranty. The manufacturer's warranty is issued only after the manufacturer's representative conducts a post-installation inspection, and the property owner should receive the actual warranty certificate rather than just the installer's promise that the warranty was filed. Confirm both documents are in hand before releasing final payment.
