Flat roofs in Royal Palm Beach are the lanais, the garages and the additions on the canal-lot houses, and the low-slope sections on the attached villa rows where one unit meets the next. They were built after the tile roof went on, tied in by whoever built them, and they leak at the wall and the tie-in first.
Molsbee Roofing repairs and replaces them in TPO and modified bitumen from our shop in Lake Worth Beach. A Molsbee roofer walks the membrane, checks the drainage and the flashing where the tile drains onto it, and gives you a written price for a repair or a new roof.
We are a Florida Certified Roofing Contractor CCC1327429; the phone at 561-318-8624 is answered at all hours.

Before flat roof work in Royal Palm Beach
Where the tile drains onto the lanai roof
On a Royal Palm Beach canal-lot house the flat section is the lanai, the garage or the addition, and it sits below a tile roof that sheds straight onto it. That water runs to the wall, sits against the upstand and gets behind flashing set too low, and the stain shows inside a room away from the leak.
The repair rebuilds the junction: membrane carried up the wall to height, new flashing, the tile above relaid over it. On an attached villa row the low-slope section at the party wall is flashed so neither unit leaks into the other.
Standing water and the shade
A flat section with no fall holds water, and the membrane under a puddle is the first part of the roof to fail. In Royal Palm Beach the usual causes are a low spot in the deck, a scupper set above the roof surface, or an outlet packed with leaf litter; the village has been a Tree City USA since 1990 and the shade that comes with it drops leaves onto every low roof.
We start each inspection at the drainage, clear it, and where the roof needs it rebuild the low spot with tapered insulation board so the water has a way off.
TPO or modified bitumen, and the ProjectDox permit
TPO is a single-ply membrane with heat-welded seams; it suits a larger, open section and we are Carlisle-certified to install it. Modified bitumen suits a small lanai roof with walls to climb.
Either goes over a re-nailed deck, and it gets the self-adhered secondary water barrier we specify and is fastened for the 160 mph wind band the village sits in. The permit is filed on the village ProjectDox portal with a Contractor Data Sheet, the Roof Spec Sheet and the Re-Roof Nailing Affidavit; residential review runs 7 to 10 business days, and inspections are booked on the automated line.
Repair or replace on a 1990 roof
A split seam, a failed outlet or a wall flashing that has let go is a repair. A membrane coated over its own failures, or a deck that gives underfoot, is a replacement.
We check with the village how the quarter-roof rule applies before the scope is set. Roofr does not record which of our Royal Palm Beach roofs carried a flat section, so this page gives no flat-roof count, and the flat roof in our photograph is captioned by material only.
How it works in Royal Palm Beach

Permits in Royal Palm Beach
For work in Royal Palm Beach, confirm requirements with the building department responsible for the property and complete any required historic or HOA review before ordering materials or beginning work.
Royal Palm Beach's Building Department at 1050 Royal Palm Beach Boulevard takes the roofing permit on ProjectDox, where a Contractor Data Sheet replaces the paper application. The village publishes its review time: 7 to 10 business days for residential, 15 to 30 for commercial, and a permit stays valid for 180 days.
Roofs carry two village forms, the Re-Roof Nailing Affidavit and the Roof Spec Sheet. Inspections are booked on the automated line with a three-digit code, and the inspector's arrival window is given by phone between 7:30 and 8:30 in the morning.
The village is about 15 miles inland, in the 160 mph wind band and the wind-borne debris region. Our covering replacements include a self-adhered secondary water barrier.
- A canal grid from 1959
- The village was incorporated in 1959 on a canal grid dug for developer Arthur Desser's drainage project, 11.7 square miles between Southern Boulevard and Okeechobee Boulevard. Lot drainage and roof runoff are looked at together.
- Homes from 1990
- The typical Royal Palm Beach home dates to 1990, in neighbourhoods like Crestwood, La Mancha and Madison Green.
- Attached villas share a roof line
- In a villa row the neighbours' roofs set the timing and the tile match, so one unit at a time is normal. Tree City USA since 1990 also means shade and leaf litter sitting on the roof.

Flat roof repair and replacement questions in Royal Palm Beach
What should a flat roof repair cost in Royal Palm Beach?
The repair figure above is county-wide: every repair we signed across Palm Beach County last year, because our Royal Palm Beach repairs are too few for a village figure. Within that range, a scupper or a single wall flashing sits at the low end and a rebuilt tile 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, TPO or modified bitumen, after we have walked it.
My lanai roof leaks where the tile meets it. Why?
Because the lanai was roofed after the tile went on and the junction was never flashed to a proper height. Tile sheds everything it catches onto the membrane below; the water runs to the wall, sits against the upstand and works in behind the low flashing, and the stain shows up inside well away from the leak.
The fix is to carry the membrane up the wall, flash it properly and relay the tile above over the new work. Patching the middle of the section does nothing for a leak at the wall.
Does a flat roof repair need a village permit?
A small repair may not; a re-roof of the section does, and we check with the village on anything in between. The permit goes through ProjectDox with the Roof Spec Sheet and the Re-Roof Nailing Affidavit, the village publishes its residential review at 7 to 10 business days, and the permit stays valid for 180 days.
We file the day you sign and book each inspection on the village automated line, with the inspector's arrival window given by phone in the morning.
Should the flat section be done with the rest of the roof?
Often, yes, because the tile roof above the lanai is usually at the end of its underlayment as well, and a large repair can bring in the quarter-roof rule. We check with the village how much of the roof a repair permit may cover before you decide.
You get both prices on one sheet, the section alone and the whole roof, so the choice is made on numbers rather than on a hunch.
