After rooftop HVAC work in Forney
Where a Forney shop or business has rooftop equipment, a replacement or service visit can affect access paths, curbs and drainage. Plan the roof interfaces alongside the mechanical work.
A membrane roof is not a work platform
Tools, removed components and repeated access can put loads and traffic onto a membrane roof. The permitted access route, protection and storage arrangements depend on the system and the job. Dropped fasteners or dragged metal can damage a surface even when the work concerns equipment above it.
Agree roof protection before work begins. Afterward, qualified personnel should check the agreed access route and work area for cuts, disturbed details and debris. Building occupants do not need to climb onto the roof to prepare for that assessment.
Curbs, penetrations and drains
If the new unit needs a curb adapter or altered lines, its roof connections must suit the existing system. Identify who is responsible for curbs, penetrations and flashing. TPO details, modified bitumen assemblies and metal roofs use different compatible materials and installation methods; a generic surface seal does not establish a complete connection.
Packaging or loose material can obstruct drains and scuppers. Check that the work has not blocked drainage or diverted runoff toward a vulnerable joint. The inspection should also consider whether the equipment or supports create a new obstruction, not merely remove visible debris.
Agree up front who owns the flashing. The mechanical contractor sets the unit; the roof detail around it is roofing work. The commercial roof repair page explains what that repair involves.
Put it in the roof record
Keep the work date, unit location, contractor and agreed roof-access route in the building record. Ask qualified personnel to document the affected roof details as part of the agreed work. Report any new interior leak promptly from a safe location; timing helps an investigation but does not by itself establish cause.
If the building has a maintenance plan, confirm whether post-trade checks are included, their timing and how repairs are authorized. Add the findings to the same roof record so later work starts with useful history.
