Flat roofs in West Palm Beach show up in two places: behind the parapet walls of some 1920s Mission style houses, and over the porches, carports, Florida rooms, and additions that owners have built onto homes ever since. APEX Roofing of Delray Beach replaces and installs flat roofs in West Palm Beach from our office in Delray Beach, using modified bitumen applied straight to the deck. Prices start at $6.50 to $7.50 per square foot of roof, and we look at how the roof drains before we write the quote.
Our residential flat roof is modified bitumen bonded to the deck. TPO stays on large commercial roofs.
We check drains, scuppers, and low spots before pricing, because ponding water shortens a flat roof's life more than anything.
Installed price with the tear off, permit, and haul away included.
Wet decking under a flat roof is priced on its own line in your estimate, so nothing is added later.
A flat roof usually gives warning before it fails. Most of these signs point to a roof near the end of its life, and the last one often does not.
On most West Palm Beach homes the flat roof covers a porch, carport, Florida room, or addition instead of the whole house, so the size of that section shapes the total more than any other factor.
Shingle, tile, and metal jobs include all rotted decking. Flat roofs work differently: wet decking under a flat roof is priced separately and shown in your estimate before you sign, so the final bill matches what you agreed to.
We price per square foot of roof, and a carport or Florida room costs a fraction of a whole flat roofed house.
A roof that meets a parapet wall, or a porch roof that ties into the main roof, needs that joint rebuilt and flashed so water cannot slip behind it.
We check drains, scuppers, and low spots before quoting, and anything needed to stop water from sitting is listed as its own line.
Air conditioning units and vents sitting on the roof must be raised or worked around, then flashed again.

Starting prices, not a quote. Financing can split the cost into monthly payments. When state funding is open, homesteaded homes built before 2008 may qualify for up to $10,000 in hurricane hardening through My Safe Florida Home.
Drainage, edges, and the joints with the rest of the house decide how long a flat roof lasts, and close to the Lake Worth Lagoon all three work harder.
The Florida Building Code calls for positive drainage, which means the roof should be dry within 48 hours after rain. Spots that hold water longer than that break the surface down early.
On older parapet houses the flashing has to turn up the inside of the wall and under the coping, and on porches and additions it has to tuck under the main roof. Those two joints are where most flat roof leaks here begin.
Along the Lake Worth Lagoon and the brackish canals, salt air eats at edge metal, flashing, and scupper linings faster. We note how far the house is from the water and pick those parts to match.
The steps match any roof replacement, with extra time on drainage and on the joints at walls and the main roof.
We look at the surface, check the deck from below, test drains and scuppers, and look at every wall joint and edge.
You get the roof system, any drainage work, and the price on paper, with wet decking on its own line.
We file on the City of West Palm Beach Civic Access portal, or with Palm Beach County for homes outside city limits, and start once the permit is issued.
The old roof comes off, wet decking is replaced, and the deck is inspected before the new roof goes on.
The modified bitumen goes down, every wall, joint, and drain is flashed, and the final inspection closes the permit.
Real reviews from homeowners across Broward and Palm Beach counties.
We serve homeowners throughout West Palm Beach, including Flamingo Park, Old Northwood, Grandview Heights, Prospect Park, the South End, and the neighborhoods west of I-95.
Often it can. When the leak sits in one place, like the joint with the main roof or a split seam, and the rest of the surface is sound, a repair is the better buy. Our free inspection tells you which way to go, and our roof repair page explains the process.
A coating can add years to a membrane that is still sound and dry underneath. It cannot fix wet decking, failed seams, or water that ponds on the roof, and it seals in whatever moisture is already there. An inspection shows whether the roof underneath is worth coating or due for replacement.
For homes we use modified bitumen bonded to the deck. It takes foot traffic well, repairs cleanly, and is the usual residential flat roof. TPO and EPDM belong mostly on commercial buildings with big open roofs.
Modified bitumen usually gives about 15 to 25 years here. Good drainage, scuppers cleared after storm season, and edge metal suited to salt air are what move it toward the longer end.
When both are old, usually yes. Most leaks start at the joint where the flat roof meets the main roof, and replacing both at once means that joint is rebuilt one time instead of opened twice. See our tile roofing page for the main roof.
