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.

Before flat roof work in Greenacres
The Florida room tie-in on a block house
Greenacres was built up in the 1980s, and the Florida room, the roofed-over lanai or the later garage on a block house meets the main roof at a wall or a fascia. That junction is where the water gets in: the shingle above drains onto the membrane, the run-off heads for the wall and finds flashing that stops short.
We rebuild the tie-in with the membrane run up the wall to height and the shingle above relaid over new step flashing. On a villa the low-slope section at the party wall is shared with a neighbour, and we flash it so both units stay dry.
Why the water will not leave
Standing water on a Greenacres flat section usually traces back to the deck rather than the membrane: an older addition can sag between its joists, the low point ends up away from the scupper, and a puddle sits there for days after every summer storm. A membrane under standing water fails first, so the inspection starts by finding where the water goes and why it stops.
The fix runs from clearing a blocked outlet, to resetting a scupper, to rebuilding the fall with tapered insulation board over a re-nailed deck.
TPO or modified bitumen, and the city's live inspections
TPO, a single-ply membrane heat-welded at the seams, suits a larger, open 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, fastened for the 160 mph band Greenacres sits in, over the self-adhered secondary water barrier we specify. The City of Greenacres accepts no roofing affidavits: sheathing, tin tag and in-progress are live inspections before the final, each requested by 3 pm the business day before, and the permit is filed on MGO Connect with the city's Roof Package form.
Repair or replace a flat section
A 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 Roofr records list the roof, not whether it carried a flat section, so there is no Greenacres flat-roof count on this page.
How it works in Greenacres

Permits in Greenacres
For work in Greenacres, confirm requirements with the building department responsible for the property and complete any required historic or HOA review before ordering materials or beginning work.
Greenacres runs its own Building Division at 5800 Melaleuca Lane, weekdays 8 to 4:30, and since 15 April 2026 the roofing permit is filed on MGO Connect only; emailed applications are no longer accepted. The city wants its own Roof Package form, the contractor enrolled on the portal and a certified notice of commencement on file before inspections start.
Greenacres accepts no affidavits on roofs. Sheathing, tin tag and in-progress are live inspections before the final, each requested by 3 pm the business day before, Monday to Friday. We hold the schedule for the inspector.
The city sits inland in the 160 mph wind band and the wind-borne debris region; the code sets secondary water barrier requirements on a re-roof, and we specify a self-adhered one.
- A city that grew in the 1980s
- Greenacres went from 1,731 residents in 1970 to 18,683 in 1990, and the typical house dates to 1987.
- Flood pockets since 2017
- The city was once entirely Zone X. Since 5 October 2017 it has carried AE and AH flood pockets, and the county's new flood maps took effect in December 2024, so we check the parcel before the proposal.
- Storm history in the record
- The 1926 and 1928 hurricanes virtually destroyed the town. Every roof from 10th Avenue North to Ferreri Community Park and Heather Estates Park is designed for 160 mph gusts today, and the fastening schedule is written into the proposal.

Flat roof repair and replacement questions in Greenacres
What does a flat section repair cost in Greenacres?
The repair figure above covers every repair we signed across Palm Beach County last year, not Greenacres alone, because our repairs inside the city are too few to support a city figure. Where a job lands in that range depends on the scope: resetting a scupper or one wall flashing at the low end, a rebuilt tie-in with tapered board at the high end.
A full re-roof of the section is priced by the square and by the system once we have walked it and probed the deck.
My Florida room roof leaks where it meets the house. Why?
Because the room was added after the main roof and its flashing at the wall stops short. The shingle above sheds onto the membrane, the run-off heads for the wall and slips behind the low flashing, and it shows as a stain along the ceiling edge of the room.
We rebuild the tie-in with the membrane run up the wall, new step flashing set at height, and the shingle above relaid over it. A patch in the field of the membrane will not touch a leak that starts at the wall.
Does a flat roof repair need a permit in Greenacres?
A re-roof of the section does; for a small repair we check with the city first. Inside the city limits the permit goes on MGO Connect with the Roof Package form, and Greenacres inspects the sheathing, the tin tag, the roof in progress and the final in person, with no affidavits, each inspection requested by 3 pm the business day before.
On the county side of the mailing area the permit is the county's, filed on ePZB with its own flat-roof form, and we file whichever applies.
Should I replace the whole roof at the same time as the flat section?
Often, because on a 1987 house the main roof and the section are of an age and reach the end of their underlayment together. If repairs, replacements or roof recovering cover more than a quarter of a roof system or section in any 12-month period, the code generally requires replacing or recovering the roof covering across that entire system or section to meet current code requirements.
If that system or section was built, repaired or replaced in compliance with the 2007 Florida Building Code or a later edition, only the portion being worked on must meet applicable current code requirements. Our inspection helps determine which applies to your roof.
We price the section and the whole roof on one sheet.
