Flat roofreplacement cost
Outside cost guides put a flat roof replacement at about $4 to $14 per square foot installed, or roughly $4,000 to $22,000 for a house-sized roof.12 Those are published figures, not Lifetime's price. We price each roof in writing after a free inspection.
What outside guidessay it costs
Six published guides give flat roof prices, and they agree more than they differ. Most land between $4 and $14 per square foot, installed, once you pick a membrane.
Outside ranges, not Lifetime's prices
None of the six is a government or consumer-body survey, so no neutral source exists for this number. HomeAdvisor, Fixr, RoofVista, and RoofCostCalculatorTexas are lead-generation sites. This Old House is a publisher, and The Roofing Brief is run by a contractor.

What movesthe price
Roof size and membrane move a flat roof price the most. The guides name the same handful of other items that push a total up or down.
- Size of the roof, since every guide prices by the square foot.1
- The membrane. TPO, EPDM, PVC, modified bitumen, and built-up sit at different prices; our flat roof material guide covers the choice.4
- Tear-off or recover. HomeAdvisor lists removal at $1,000 to $1,500 extra, and Fixr says $1,000 to $5,000 if the estimate leaves it out.12
- Insulation upgrades and drainage improvements, which This Old House says a contractor may add.3
- Permits, which HomeAdvisor puts at $250 to $600 on top of the per-foot price.1
Short version. A low per-foot price can hide removal, insulation, or drainage work that gets added later.
What a written quoteshould show
A flat roof quote you can compare names the membrane, the square footage, and whether the old roof comes off. Without those lines, two totals aren't the same job.
Look for removal, insulation, drainage work, and permits listed as their own lines or marked as not included. If water pools on your roof now, ask how the quote fixes it; our ponding water guide explains what to ask.
