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.

Where the tile drains onto the flat
On a Royal Palm Beach house the flat section sits below a tile roof, and the tile drains onto it. The water runs to the wall, sits against the upstand and gets behind flashing that was set too low, and the stain shows up inside a room away.
The repair rebuilds that junction: membrane carried up the wall to a proper height, new flashing, the tile above relaid over it. On a villa row the low-slope section at the party wall is flashed so neither unit leaks into the other.
Ponding and drainage
- A flat section with no fall holds water, and water still there days after rain means a low spot, a blocked outlet or a scupper set too high. The membrane under it is the first thing to fail.
- We start with where the water goes, clear the drainage, and where the roof needs it rebuild the low spot with tapered insulation board so the section drains.
TPO or modified bitumen, and the village permit
A TPO single-ply membrane with heat-welded seams suits a larger, cleaner section, and we are Carlisle-certified to install it. Modified bitumen suits a small lanai roof with walls to climb.
Both go over a re-nailed deck with insulation board where needed. Where a permit is needed it goes through the village's ProjectDox system with a roof spec sheet, comes back inside the village's published review time, and the inspections are booked on the automated line.
Repair or replace, and our village work
One split seam, a failed outlet or a wall flashing that has let go is a repair. A membrane that has been coated over its own failures, or a deck that gives underfoot, wants replacing.
Our records do not say which of our Royal Palm Beach roofs carried flat sections, so there is no flat-roof count on this page, and the flat roof in our photograph is captioned by material only.
What should a flat roof repair cost in Royal Palm Beach?
The figure above is county-wide, our registered number for every repair we signed across Palm Beach County last year, because our village repairs are too few for a town figure. A scupper or one wall flashing is at the low end and a rebuilt tie-in at the high end.
A full flat re-roof is priced by the square and by the system, after the walk.
My lanai roof leaks where the tile meets it. Why?
Because the lanai was roofed after the tile and the junction was never flashed to a proper height. The tile sheds water onto the membrane, the water runs to the wall and works behind the low flashing.
We carry the membrane up the wall, flash it, and relay the tile over the new work.
Does a flat roof repair need a village permit?
We check with the village whether a small repair needs one. A re-roof of the section does, through ProjectDox with a roof spec sheet, and the village keeps to its published review time.
We file it the day you sign and book the inspections on the automated line.
Should the flat section be done with the rest of the roof?
Often, on an older house, because the tile roof above may be at its underlayment, and we check with the village how much of the roof a repair permit may cover. Both prices go on one sheet, the section alone and the whole roof, so the choice is made on numbers.
