Single-ply
TPO
A heat-welded thermoplastic membrane and the usual specification on newer flat commercial roofs. Reflective, and the welds are testable.
TPO
North Richland Hills, TX
Commercial repair, restoration and replacement for North Richland Hills properties, with the roof system and the building’s use considered together.
Commercial roofing
A useful commercial roofing estimate begins with the existing system, the leak history and the condition below the surface. Seams, penetrations, roof edges and drainage deserve attention alongside the open membrane.
Local failures on a sound system may suit repair. A weathered but serviceable roof may be a restoration candidate after needed repairs. Widespread wet insulation or deterioration can point toward replacement.
The extent matters. A small wet area that can be removed and repaired is a different problem from damage spread across the building.
Moisture surveys and test cuts may be needed to define the work. Confirm the investigation and any formal report separately from the free initial inspection.

These systems offer different ways to cover a low-slope building. Tell us which is on your roof, or describe what you know; the inspection can help identify it.

TPOSingle-ply
A rubber membrane with a long service record on large low-slope roofs. Seams are adhered, not welded.
Single-ply
A heat-welded membrane with product-specific chemical resistance. Exposure from kitchen exhaust should be considered when selecting the assembly.
Layered
A reinforced asphalt sheet system with assembly choices for the building’s use and access.
Flat roof
Rebuild a roof when deterioration, wet insulation or the existing assembly makes local work inadequate.
Flat roof replacementRestoration
A fluid-applied system that extends the life of a sound existing roof without a tear-off.
Roof coatingsFlat roof
Ponding, split seams and punctures on a low-slope section that is otherwise sound.
Flat roof repairFor another existing system, tell us what it is or share the information you have so suitable service can be confirmed.
What a building job covers
The line items a building owner should expect to see itemized instead of bundled.
Identify the existing system and assess visible failures, roof details and access for further investigation.
Determine whether hidden moisture investigation is needed, and define the affected area rather than assuming the whole roof is wet.
Welding, patching or re-adhering the joints where single-ply systems usually let go first.
HVAC curbs, vents, conduit and pipe boots, sealed and flashed properly instead of caulked.
Clearing and re-flashing drains, and identifying where water is standing longer than it should.
Coping, edge metal and terminations, which is where wind gets under a membrane.
Replacing saturated board instead of roofing over it, priced by the area found wet.
Staging, crane or hoist access, and the working hours the building can accommodate.
Anything the survey cannot settle before work starts, particularly wet insulation area, should carry a named unit rate in the estimate so it stays simple math later.
The work plan needs to fit the building, with disruptions identified before the job starts.
One
Inspect the existing roof and determine what further testing, measurements or access are needed to specify the work.
Two
An itemized estimate naming the system, the repair area, the unit rates and what is excluded. One number.
Three
Access, staging, noise and working hours agreed before the crew arrives, so the tenants are not a surprise.
Four
Agree the sequence, temporary protection and weather contingencies for the areas being worked on.
Five
Confirm the closeout inspection, maintenance instructions and records included in the contract.
Building-owner questions
What building owners here actually ask.
It may be possible to phase the work around operations. Noise, odors, lifting areas, interior protection and emergency access can still require restrictions. Tell the roofer what must remain usable so those needs shape the plan.
The membrane, insulation, deck and drainage need to be considered together. A local failure may suit repair; a sound compatible roof may qualify for coating after preparation. Extensive deterioration may make replacement more useful.
Standing water that persists for more than a day or two is worth attention. It is usually a drainage or a deflection issue rather than a membrane one, and it accelerates the aging of whatever it is sitting on. It should be identified in the survey.
It can damage the membrane, insulation or roof details, depending on the system and impact. A parking-lot view cannot establish the extent. Our storm guide separates reported weather from what an inspection can establish.
Coverage may come from the contractor, manufacturer or an eligible system program. Read what is offered for this assembly, including installation coverage, exclusions, maintenance and term. Manufacturer approval of a contractor should be verified where the program requires it.
