Commercial Flat Roof Replacement in North Richland Hills, TX
Commercial flat roof replacement: full tear-off and rebuild for low-slope roofs past repairing, measured and priced in writing.
Flat roof replacement
Know what is failing beneath the surface.
A commercial flat roof replacement becomes useful when the existing assembly can no longer support a dependable repair or recover. Deteriorated membrane, extensive wet insulation, deck problems and drainage can all change the decision.
Wet insulation needs to be addressed before a new roof goes over it. The area affected matters: localized removal and repair may be possible, while widespread damage can require a larger rebuild.
A recover is a separate option where the existing roof, code and selected system permit it. The estimate should make clear what stays and why it can stay.
Agree how hidden deck and insulation work will be priced and approved when its full extent cannot be determined before opening the roof.
Flat-roof work in full
What goes into a commercial flat roof replacement in North Richland Hills
The stages of a tear-off, each of which should appear on the estimate.
- Moisture survey
Mapping where the insulation is wet, which sets the work and most of the price.
- Tear-off and disposal
Removing the failed system down to the deck, containerized and hauled off.
- Deck inspection and repair
Corroded steel or rotted wood found once the roof is open, priced per unit.
- Insulation and cover board
New board to the specified R-value, with a cover board where the system calls for one.
- Membrane installation
TPO, EPDM, PVC or modified bitumen, mechanically fastened or fully adhered as specified.
- Drainage correction
Tapered insulation, drains and scuppers, so the new roof sheds water instead of holding it.
- Perimeter and edge metal
New coping, edge metal and terminations, which is where wind uplift begins.
- Penetrations reset
HVAC curbs, conduit, vents and pipe boots re-flashed into the new system.
Deck condition is only fully knowable once the old roof is off. A named per-unit rate keeps that discovery from becoming a negotiation once the crew is on site.
How a replacement runs.
The roof scope and building access need to be planned together.
Two
Specify the system
Membrane, insulation R-value, attachment method and drainage strategy, chosen for the building, not the catalog.
Three
Itemized estimate and schedule
Itemized price, unit rates for deck and insulation, and a working schedule that fits your operations.
Four
Tear off in sections
Plan the opening sequence, temporary protection and weather contingencies around the actual roof area.
Five
Final walk and documentation
Confirm the final checks, required inspections and closeout documents included in the project.
Flat-roof questions
Before replacing a commercial flat roof
Work, price and disruption.
How do I know it needs replacing instead of repairing?
The extent of membrane deterioration, moisture and deck problems matters. Ask what the investigation shows, whether local removal and repair can leave a sound roof, and what a coating or recover would require. Specialized testing may be a separately agreed part of that investigation.
Can you roof over the existing system?
Sometimes. A recover, usually in TPO, is faster and cheaper, and it is only honest where the existing board is dry and the assembly permits it. Recovering over saturated insulation seals the water in and shortens the life of the new roof considerably.
Does the business have to close?
Some projects can be phased around occupancy, but interior protection, noise, odors and lifting access may require restrictions. Explain the operating needs before the work is priced, so the plan can address them.
What happens if the deck is damaged underneath?
The damaged area needs assessment and suitable repair before supporting the new assembly. Agree unit rates and an approval procedure in advance. Structural damage may also need design input and a revised permit scope.
How long does a replacement take?
The schedule depends on the roof area, the system and the weather, and any roofer giving you a duration before surveying the roof is guessing. What you can insist on is a schedule in writing once the work is settled.
