TPO Flat-Roof Replacement & Tapered Insulation.
For flat and low-slope roofs, a 60 or 80 mil TPO membrane (a single tough waterproof sheet) over a layer of insulation built up at a slight slope is the modern standard: energy-efficient, durable, and — because of that built-in slope — designed to drain instead of letting water pool.
Overview
It's also how we replace aging modified-bitumen (an older asphalt-based flat roof, also called mod-bit) and tar-and-gravel roofs — same heat-welded, watertight system, sized to your building.

From a real inspection
When a flat roof is holding water you can’t see.
On a low-slope roof the damage hides under the membrane. This one looked okay on top, but a moisture scan told the real story.
What we found
- A moisture meter found water trapped under the membrane on every section of the roof, including around the skylights, an old swamp-cooler duct, and the other penetrations.
- There was a long crack letting more water in. Once moisture is sitting under the membrane like this, sealing the top won’t dry it out.
How we fix it
- We replace the membrane so the roof is watertight again and the trapped moisture is gone, not sealed in.
- Caught at this stage, before the decking rots, it’s a straightforward replacement instead of a tear-into-the-structure job.
Your configuration options
60 mil vs. 80 mil
Thickness for the durability and warranty level you want.
Mechanically fastened vs. fully adhered
Fastened is efficient and economical; fully adhered glues the membrane down for a smooth, seamless-looking surface with no fasteners showing.
What’s included
Every flat-roof replacement, start to finish.
01
Full tear-off to deck
Complete removal of the old roof down to a clean, solid base layer.
02
Deck inspection
We check the wood decking for damage before anything goes back on.
03
Sloped insulation
Insulation built up at a slight slope so water runs to the roof drains instead of pooling.
04
Heat-welded, tested TPO seams
Seams are hot-air welded and tested, fusing the roof into one continuous surface.
05
Sealed roof openings
Every spot where a pipe or vent comes through the roof is sealed with a snug TPO sleeve and clamped down tight.
06
Sealed, locked-down roof edges
Metal bars around the roof's edges lock the waterproof sheet down so water can't get underneath.
07
New TPO-wrapped roof drains
The roof's drain openings (scuppers) are re-wrapped in TPO so they tie seamlessly into the rest of the waterproof roof.
08
Cleanup & haul-off
Full debris removal and site cleanup when the job is done.
