TPO, PVC, or ModBit — what's the difference?

TPO is a cost-effective reflective single-ply, PVC is more chemical- and heat-resistant (great for restaurants), and modified bitumen is a proven multi-ply system. We match the membrane to your building's use and budget.

Should I replace or coat my flat roof?

If the substrate is sound, a restoration coating can add 10–20 years for a fraction of a tear-off — and it's a maintenance expense, not a capital project. See our coatings page for the math.

Do you do commercial flat roofs?

Yes — warehouses, strip centers, churches, and multi-tenant buildings, including large-scale work. We coordinate around your tenants and operations.

How long does a flat-roof install take?

It depends on size and system, but we schedule tightly and stage materials to minimize disruption. Most restorations avoid downtime entirely.

What warranty comes with a flat roof?

Single-ply and coating systems carry manufacturer warranties (10/15/20-year on Sherwin-Williams coatings) plus our workmanship coverage.

The systems

The right membrane
for how you use the building.

There's no single "best" flat roof — there's the best one for your building in Florida. Here's how we choose.

TPO

Reflective, cost-effective single-ply. The workhorse for warehouses and retail.

PVC

Chemical- and grease-resistant. The go-to over restaurants and kitchens.

Modified Bitumen

Proven multi-ply toughness for foot traffic and complex details.

Restoration Coating

Add 10–20 years with no tear-off — a maintenance expense, not capex.

The #1 flat-roof killer

Standing water
is a countdown clock.

Ponding water accelerates membrane failure and voids many warranties. We correct drainage and slope where possible, then install or coat with a system built to shed water — not hold it.
