TPO, modified bitumen, and coated flat-roof systems for South Florida homes and businesses — built to handle standing water and our summer downpours.
Flat & Low-Slope Roofing
Flat and low-slope roofs — over Florida rooms, additions, carports, porches, and plenty of mid-century and commercial buildings — don’t shed water the way a steep roof does. Water sits, finds the smallest gap in a seam, and works its way in.
That’s why on a flat roof the membrane and the seams are everything. We install low-slope systems as one fully sealed surface, with drains, edges, and every penetration detailed for water that stands, not just water that runs off.
And not every leaking flat roof needs to come off. If the roof is still sound underneath, a silicone coating can seal it and add years for a fraction of a tear-off. We’ll tell you honestly which one your roof needs.
Warning signs
Flat roofs give warning signs before they fail completely. Catching them early is often the difference between a coating and a replacement.
Water that sits more than a day or two after rain stresses the membrane and finds every weak seam.
Blistering and cracking mean the membrane is aging or moisture is trapped underneath.
Open or lifting seams are the most common place flat roofs leak.
Stains under a flat section often show up far from where the water is actually getting in.
Plants, algae, or debris collecting on the roof hold water and wear the surface down.
Many low-slope systems are in their later years by this point — a good time for an assessment.
Systems we install
The right system depends on your roof’s slope, deck, drainage, and how it’s used. We match the system to the roof instead of forcing one product.
A white, heat-welded single-ply membrane. The seams are welded together, and the bright surface reflects the sun.
A durable, multi-layer asphalt-based system that handles foot traffic well and has a long track record on low-slope roofs.
A seamless, reflective coating over an existing roof that’s still sound — restoration instead of replacement.
| Silicone coating | Full replacement | |
|---|---|---|
| Best when | Roof is sound and dry underneath | Roof is saturated or failing |
| Tear-off | None | Full tear-off |
| Disruption | Minimal | More |
| Cost | A fraction of replacement | Higher |
| Added life | Roughly 10–15 years | 15–25 years |
A moisture check tells us whether your roof is a coating candidate. If it isn’t, we’ll say so.
What to expect
We check the membrane, seams, drains, and flashing, and find where water is getting in or sitting.
Repair, coating, or replacement — you get a clear written recommendation and quote.
We clean the roof, make repairs, and detail drains and edges so the new system bonds and drains right.
We install the system or coating as one sealed surface and walk the finished roof with you.
Why Hunter
There’s no slope to forgive a sloppy seam. We take the extra time at seams, drains, and edges because that’s where flat roofs win or lose.
Seams and penetrations are detailed to stay watertight where water ponds after a storm.
TPO, modified bitumen, or coating — we recommend what fits your roof and your budget.
If a coating will do the job, you won’t get talked into a tear-off.
Good questions

Because water doesn’t run off — it sits. Any weak seam, failed flashing, or low spot that ponds gives water time to work in. On a flat roof the membrane and the seams do all the work, so that’s where the quality has to be.
Mainly TPO and modified bitumen for low-slope roofs, plus silicone coatings to restore roofs that still have life in them. We match the system to your roof’s slope, deck, and use.
Often, yes — if the roof is still structurally sound and not saturated with water, a silicone coating can seal it and add years for a fraction of a replacement. If it’s too far gone, we’ll tell you straight.
Ponding is water that sits more than a day or two after rain, usually from low spots or poor drainage. Over time it stresses the membrane and finds seams. We address drainage as part of the job rather than ignoring it.
TPO is a white, heat-welded single-ply membrane that reflects the sun. Modified bitumen is a multi-layer asphalt-based system that handles foot traffic well. Both are proven on low-slope roofs; the right one depends on your roof.
Both. On homes that’s usually Florida rooms, additions, porches, and carports; on businesses it’s the main low-slope roof. The systems overlap; the details change with the building.
It depends on the system and the sun, but a properly installed low-slope membrane generally runs 15 to 25 years, and a silicone coating can add roughly 10 to 15 more when it’s applied before the roof fails.
Yes. Where a flat section meets a sloped roof is a common leak point, and we flash those transitions carefully as part of the job.
What homeowners say
Hunter Construction replaced the roof on our home. It’s great to work with a small business that makes you feel at home — I’ve found my roofing contractor in Palm Beach County.
Very professional. Wouldn’t go with anyone else — they’ll treat you right.
I’ve sold roofs for numerous companies all over, and I’ll always recommend Hunter Construction for commercial and residential work.
