When to Replace a Flat Roof (Not Repair)
Let us be clear. A flat roof can be repaired. Small seam failures. Punctures. Flashing issues. But
when the membrane is old, widespread, or the insulation is wet, replacement is the better
option. Here are the signs.
Age. TPO and EPDM last 15 to 20 years. Modi ed bitumen lasts 15 to 20 years. Built-up
roofing (BUR) lasts 20 to 25 years. If your flat roof is over 18 years old, replace it. Repairs are
throwing money away. You will be calling us every year.
Wet insulation. Water that gets into the insulation does not dry out. It stays there, rotting the
decking and degrading the membrane from below. We use a moisture meter to detect wet
insulation. If more than 20% of the insulation is wet, replacement is required.
Multiple repairs. If you have had three or more repairs in the last ve years, the roof is failing.
Replace it. Each repair is a band-aid on a broken bone.
Ponding water. If water ponds for more than 48 hours after a rain, the membrane is
degrading. Ponding water also adds weight (8.3 lbs per gallon). Over time, it causes the
membrane to soften and fail.
Blistering or shrinking. TPO shrinks over time. It pulls away from flashings and edges.
Blisters indicate trapped moisture. Both are signs of end of life.
Interior leaks. If you have leaks inside the building, the membrane has failed. Patch it
temporarily, but plan for replacement.
Fort Campbell families, at roofs on base housing are replaced on a schedule. We work with
the housing office.
How We Replace a Flat Roof (Step by Step)
- Free inspection and measurement. We measure the square footage with a laser tool. We
check for wet insulation with a moisture meter. We take core samples if needed.
- Material selection. TPO (white, re ective). EPDM (black rubber). Modi ed bitumen
(asphalt). Built-up roofing (multiple plies). We help you choose based on budget and building
use.
- Permit pulling. Required for commercial and residential flat roof replacement in
Clarksville. We handle it.
- Scheduling. For commercial, we work nights or weekends to minimize disruption. For
residential, we work during the day.
- Tear-o . We strip the old membrane. We remove wet insulation. We inspect the decking.
- Decking repair. Rotted wood gets replaced. Cost is $75 to $150 per sheet. We show you
photos.
- Insulation replacement. We install new ISO board. Thickness depends on energy code
(R-25 to R-30 for commercial, R-20 to R-25 for residential). We stagger the sheets to avoid
gaps.
- Cover board (optional). A 1/4-inch cover board over the insulation provides a smooth
surface for the membrane. Recommended for TPO and EPDM.
- Membrane installation. TPO and EPDM are heat-welded or adhered. Modi ed bitumen is
torched or cold-adhered. BUR is multiple plies of felt and hot asphalt.
- Flashing. All edges, penetrations, and walls get new flashings. This is the most critical
step. We take our time.
- Cleanup. We remove all debris. We check for sharp edges.
- Warranty. Manufacturer warranty (15-20 years). Our workmanship warranty (5 years for
commercial, 10 for residential).
