## Price

$1,250-$2,700 roofing square (100 sq ft), installed. Valentine Roofing's WA-wide contractor-published range ($31,200-$68,000 for a full low-slope replacement), divided over a typical 25-square home.

## What's included

- Membrane system (TPO or EPDM) selected for the roof's specific drainage and use
- Full tear-off with deck inspection, rotten sheathing replaced and priced separately
- Drainage and flashing detailing at every roof edge and penetration, addressing ponding-water risk
- Insulation upgrade options where the existing system is under-insulated
- Written price before work starts
- Site cleanup and haul-away of the old membrane

## Process

01. **Free inspection** - We check membrane condition, drainage slope, and any ponding-water history before quoting the job.
02. **System selection** - TPO or EPDM chosen based on the roof's use, drainage design, and budget.
03. **Tear-off and install** - Deck repaired where needed, new membrane and drainage detailing installed to manufacturer spec.
04. **Final walkthrough** - Cleanup, and a walkthrough confirming drainage performs as designed before we leave.

## When it's needed

- Visible ponding water more than 48 hours after rain
- Membrane seams separating or bubbling
- Interior ceiling stains under a flat-roofed section
- A flat roof approaching or past its membrane's rated service life
- Water pooling near a roof drain or scupper

## FAQ

**TPO or EPDM — which is right for my flat roof?**

See our dedicated comparison guide — the right choice depends on your roof's specific drainage, budget, and whether it's residential or light-commercial use.

**How do you handle ponding water?**

We address drainage slope and detailing during installation rather than just patching over an existing ponding problem, since standing water is what actually shortens a flat roof's service life here.

**Do you replace flat roofs on additions and porches, not just whole-building?**

Yes — a flat or low-slope section on an addition is a common job here and priced the same way, by the square.
