Commercial roofing in Palmetto, FL
In Palmetto, 23.5 percent of homes are in buildings with five or more units. That makes multi-unit roofs, association buildings and older commercial structures a large share of the work here. Property managers should know which permit office reviews those roofs and what the owner must supply before a job starts.

Our workPermits and paperwork
Who permits commercial roofing in Palmetto
Palmetto has its own Building Department, so roof permits go to the City of Palmetto, not to the county. Confirm the current permit requirements and forms with that office before work is scheduled.
Before the first inspection, the permitting office needs a recorded Notice of Commencement when the direct contract is above a set amount. Without one, the owner may end up paying twice for the same improvements.
A permit does not last forever. It becomes invalid if work does not start within 6 months of issue, or if work stops for 6 months. Schedule the crew with those clocks in mind.
Roof systems and drainage
Low-slope systems, drainage, and how the 25 percent rule applies
Many commercial roofs here are low-slope. New low-slope roofs must have a minimum design slope of one-fourth unit in 12, about 2 percent, for built-up, modified bitumen, single-ply and liquid-applied systems. Ask any bidder how the new design meets that slope on your building.
Florida drainage rules require positive drainage, meaning the roof must drain within 48 hours of rain. Palmetto's Manatee County setting gets heavy rain, with about 60 percent of the normal annual rainfall at Sarasota-Bradenton airport falling June through September. That is roughly 29 inches in a four-month season.
Recovering over an old roof is not always allowed. A full tear-off to the deck is required if the existing roof is water soaked, has two or more prior coverings, or has unrepaired blisters. Ask the bidder which of these applies to your building.
Comparing bids
Comparing bids for a multi-unit or association roof
- Confirm the bidder holds a roofing contractor certification or registration. A general contractor without one may not advertise as a roofing contractor.
- Ask how the bid handles deck attachment, wood sheathing and fascia repairs, since those fall within roofing scope.
- Ask how the proposal addresses ponding water and whether a structural review is recommended.
- Ask whether the owner will receive a written notice of ponding risks before work starts.
Palmetto is on the north bank of the Manatee River, across from Bradenton. Flood-prone low-lying areas along the west coast flooded during Hurricane Hermine in 2016, when more than 10 inches of rain fell at sites in Manatee County. Ask bidders how the design handles heavy rain.
Questions
Commercial roofing in Palmetto: questions
What is the 25% roof rule in Florida?
Within any 12-month span, the 25 percent rule caps the share of your roof that can be repaired, replaced, or recovered. If more than 25 percent is worked on, the entire roof covering must be replaced or recovered. If the existing roof was built or repaired under the 2007 Florida Building Code or a later version, exceptions to this limit may apply. Confirm how the rule applies to your building with the Palmetto Building Department before you sign a contract.

What is the new law in Florida about roofs?
Florida's Ninth Edition of the Building Code goes into effect on December 31, 2026. Any permit applications or plans filed on or after that date will need to comply with the new edition. Palmetto projects should confirm which edition applies with the City of Palmetto Building Department.

How do I compare roofing bids for a multi-unit building in Palmetto?
Check that the bidder holds a roofing contractor certification or registration. Ask how the bid handles deck attachment and wood sheathing, and how the design deals with ponding water. With 23.5 percent of Palmetto homes in buildings of five or more units, many associations face these questions. Get written answers before you choose a bidder.
