Re-Roof Over Difficult Decks with Fleece-Back TPO Roofing Membrane
Fleece-Back TPO Roofing Membrane Manufacturer for Re-Roofing
Our fleece-back TPO roofing membrane pairs a heat-weldable top ply with a bonded polyester fleece underside, so one sheet can be glued down, fastened, or laid over aging surfaces. Send your existing roof type, deck condition and planned attachment method, and we will advise a fleece weight and sheet thickness that match the job.
Cushioned Single-Ply Sheets for Demanding Roof Substrates
Bonded Polyester Fleece for Adhesive Grip
In a fleece-back TPO roofing membrane, adhesive soaks into the fleece fibers and locks mechanically, which spreads wind uplift across the whole roof surface.
Fleece weight decides how much adhesive the sheet absorbs, so it matters for material budgets.
Cushioned Underside over Rough Substrates
The fleece layer softens contact with old membranes, gravel remnants and textured boards, reducing puncture points from below.
Weldable Top Ply with Fleece-Free Seam Edge
A narrow strip without fleece along the selvedge lets hot air fuse sheet to sheet, giving a clean seam instead of a fiber-filled one.
Light-Toned Surface for Heat Control
The white face reflects sunlight, which keeps deck temperature lower and slows heat aging of the sheet.

Roof Projects Suited to Fleece-Backed Single-Ply Sheets
Re-Roofing over Existing Layers
Dry, sound old membranes can stay in place, which saves tear-off labor and disposal.
For a side-by-side look at where reinforced and unreinforced sheets each belong, see this unreinforced vs reinforced TPO roofing membrane guide.
Fully Adhered Commercial Roofs
Bonding the fleece-back TPO roofing membrane to insulation board gives a smooth, fastener-free surface on retail, office and school roofs.
Rooftop Equipment and Service Zones
Technicians servicing HVAC units walk on a surface backed by extra cushioning.
Roofs With Uneven or Textured Decks
The fibrous underside of this fleece-back TPO roofing membrane bridges minor surface irregularities that would telegraph through a bare sheet.
FAQ: Adhesive Bonding, Substrates and Roof Care
1. Does a heavier fleece use more adhesive?
Yes, thicker fleece absorbs more. Spread a test patch before ordering in volume so the coverage rate on your substrate is known.
2. Must the old roof always be removed first?
Not always. Wet insulation must come out, but a dry, sound surface can be covered. Run a moisture survey before deciding.
3. Does a fleece-back roof feel different underfoot?
It feels slightly softer because the fleece cushions the sheet. Add walkway pads along routes used every week.
4. What weather limits apply during adhesive application?
Avoid damp decks, dew and very cold surfaces, since adhesive open time shifts with temperature. A small peel test on site confirms the bond before the crew commits to full rolls.
