What\'s included with flat roof systems

Low-slope roofs need a specialist. Wrong fastening, bad seam welds, or skipped flashing details turn a $30k roof into a $5k tear-out.

  • Heat-welded TPO + PVC seams (no glue failures)
  • Mechanically fastened or fully adhered systems
  • Drainage and ponding-water solutions
  • 20-year manufacturer warranties
  • Roof restoration coatings as alternative to replacement

Our flat roof systems process

  1. 1

    Membrane + insulation spec

    Membrane thickness (45/60/80 mil), insulation R-value, and fastening pattern engineered for your structure and climate.

  2. 2

    Tear-off or overlay

    Most flat roofs allow one overlay before code requires tear-off. We inspect for trapped moisture before deciding.

  3. 3

    Membrane install

    Field membrane laid, mechanically fastened or fully adhered, all seams heat-welded or seam-taped per system spec.

  4. 4

    Flashings + warranty

    Wall flashings, drain bowls, vent boots, and curb flashings detailed. Manufacturer inspector signs off for NDL warranty.

$14,200 architectural-shingle replacement after May 2025 hailstorm

"Storm took half my shingles on a Friday. LA Roof Pros tarped Saturday morning, filed the State Farm supplement Monday, and the new roof was on within two weeks. The supplement covered everything but my $1,000 deductible."

$11,800 GAF Timberline HDZ replacement

"Quote was $3,100 less than the big-name competitor for the same architectural shingles. Crew was clean, polite, and on time — driveway cleaner than they found it. Manufacturer warranty registered the same day."

$480 flashing leak repair (single-day fix)

"Two other companies couldn't find the leak. Their guy traced it to a chimney flashing failure ten feet from where the ceiling stain showed. Permanent fix the same afternoon. Zero upsell."

Frequently asked questions

TPO vs EPDM — which is better?

TPO has heat-weldable seams and reflective white surface (energy savings). EPDM is more flexible and historically lasts longer in cold climates. Both are excellent installed correctly.

How long does a flat roof last?

TPO/PVC: 20–30 years. EPDM: 25–35 years. Modified bitumen: 15–25 years. BUR: 15–25 years. Workmanship is the biggest variable.

My roof ponds water — is that a problem?

Ponding over 48 hours violates most warranties and accelerates membrane failure. We can install tapered insulation or add drains to fix it.

Should I coat or replace?

Coatings work for a sound substrate that's 10–15 years old. If the membrane has wet insulation underneath, coating just buys you 2–3 years.
