Permit, inspection, structural, fire, energy, drainage, wind, and manufacturer requirements vary with the Houston roof assembly and proposed work. Ask the contractor to identify what applies, who provides design details when needed, and who closes permits or warranty inspections. Confirm current requirements with the responsible authority and manufacturer.
Verify insurance, fall-protection and access planning, material storage limits, equipment shutdown or intake protection, hot-work controls if relevant, and responsibility for interior monitoring. Weather contingency, temporary dry-in, water response, and daily site security should be explicit in the project plan.
Surface appearance alone may not reveal moisture or deterioration within the assembly. Define the investigation method, unit pricing or allowance, documentation, and approval path for concealed conditions before removal exposes them.
Opening more roof than can be protected within the approved work window increases exposure to sudden weather. Require daily limits, temporary protection, monitoring, and a response plan tied to actual site conditions.
