What it is, in plain terms

A liquid-applied membrane is applied over your existing roof. It seals the seams, covers minor wear, and reflects heat. That adds good years to a roof that still has them.

It costs less than a roof-over because it works with the roof you already have. That's also why it isn't for everyone: the roof underneath has to be sound. We check first, and if a coating won't hold, we say so.

Like every job we do, the exact spec is stated on your written quote, the permit is pulled, and the warranty is written in plain English.

Is your roof a candidate?

Good candidate for a coating

  • The roof deck and structure are sound: no soft spots, no sagging.
  • Seams and flashing are largely intact, with only minor wear.
  • No widespread rust-through on metal roofing.
  • Water drains within a day or two after rain, with no long-standing puddles.
  • You want more good years from the roof you have, at a lower cost than a roof-over.

Not the right fit: a roof-over makes more sense

  • Significant sagging, soft decking, or structural concerns.
  • Standing water that regularly sits for more than 48 hours.
  • Widespread rust-through, delamination, or seams failed in multiple places.
  • A roof already leaking in several spots rather than one.

If that's your roof, that's alright. We'll say so plainly and walk you through the TPO roof-over options instead.

The 10-year system

What's included

The membrane itself

A reflective liquid-applied membrane over your whole roof, with seams and penetrations sealed. The exact product and spec are stated on your written quote.

A 10-year written warranty

Workmanship and the coating itself, covered for 10 years, in plain English on your contract. Full terms on our warranty page.

The same honest process

Satellite measurement, written quote, permit pulled, a firm install date, and your 3-day right to cancel. Every job we do works the same way.

Job photos

Photos from our first coating installs are coming. We only show real jobs.

How the 10-year warranty works

  • 10 years from install, stated on the contract you sign, not in a separate booklet.
  • Workmanship and the coating are both covered: if our work or the membrane fails, we fix it.
  • To make a claim, call (813) 212-3218. A person answers, Mon–Fri 8–6.

The full plain-English terms are on our warranty page.

When we'll tell you no

Some roofs are past the point where a coating will hold. If yours is one of them, we won't sell you one. We'll say so in plain terms and quote the 45-mil and 60-mil TPO roof-over options instead: published prices, no pressure, and the same 3-day right to cancel on any contract.

Not sure if your roof qualifies?

Call and describe your roof. We'll tell you honestly whether a coating fits, and what we'd quote instead if it doesn't.
