On a Greenacres block house the flat roof is the Florida room, the lanai that was roofed over, or the garage that was added later, and on the villas it is the low-slope section where one unit's roof meets the next. Those sections were built after the main roof and tied in by whoever built them, and they leak at the wall and the tie-in long before they leak in the middle.
Molsbee Roofing repairs and replaces them in TPO and modified bitumen from our Lake Worth Beach shop, a short drive east. A Molsbee roofer walks the membrane, checks the drainage and the tie-in, and gives you a written price for a repair or a new roof.

The Florida room and the lanai
A flat section added to a block house meets the main roof at a wall or a fascia, and that junction is where the water gets in: the shingle above drains onto the membrane, runs to the wall and finds flashing set too low. The repair rebuilds the tie-in, with the membrane run up the wall to a proper height and the shingle above relaid over new flashing.
On a villa the low-slope section at the party wall is the same problem shared with a neighbour, and we flash it so neither unit leaks into the other.
Ponding, and where the water goes
- A flat section with no fall holds water, and water still on the roof days after rain is a low spot, a blocked outlet or a scupper set too high. The membrane under standing water is the first thing to fail.
- Every inspection starts with where the water goes, and a repair clears the drainage and, where the roof needs it, rebuilds the low spot with tapered insulation board so the water has a way off.
TPO or modified bitumen, and the city's inspections
A TPO single-ply membrane, heat-welded at the seams, is the choice for a larger, cleaner section, and we are Carlisle-certified to install it. Modified bitumen suits a small Florida room with walls to climb.
Both go over a re-nailed deck with insulation board where it is needed. Where a permit is needed the City of Greenacres inspects the sheathing, the roof in progress and the final in person, with no affidavits, and on the county side of the mailing area the permit is ePZB with the county's own flat-roof form.
Repair, replace, and our Greenacres work
A single split seam, a failed outlet or one wall flashing is a repair. A membrane coated over its own failures more than once, or a deck that gives underfoot, is a replacement.
Our records do not say which of our Greenacres roofs carried flat sections, so there is no flat-roof count on this page.
What does a flat section repair cost in Greenacres?
The figure above is county-wide, our registered number for every repair we signed across Palm Beach County last year, because our Greenacres repairs are too few for a town figure. A scupper or one wall flashing is at the low end and a rebuilt tie-in with tapered board at the high end.
A full flat re-roof is priced by the square and the system, once walked.
My Florida room roof leaks where it meets the house. Why?
Because it was added after the main roof and never flashed properly at the wall. The shingle above drains onto the membrane, the water runs to the wall and gets behind low flashing.
We rebuild the tie-in with the membrane run up the wall and the shingle relaid over new flashing.
Does a flat roof repair need a permit in Greenacres?
We check with the city whether a small repair needs one. A re-roof of the section does, and the City of Greenacres inspects it in person, with the sheathing, the roof in progress and the final each requested a business day ahead.
On the county side of the mailing area the permit is the county's, and we file whichever applies.
Should I replace the whole roof at the same time as the flat section?
Often, because the main roof and the section are usually of an age, and we check with the city how much of the roof a repair permit may cover. We price the section by itself and the whole roof together so the decision is made on numbers.
