Commercial roofing in Doral, FL
In Doral, 43.2 percent of homes sit in buildings with 10 or more units, so a large share of the roofs here belong to associations and property managers. Miami-Dade County is in the High-Velocity Hurricane Zone, and the City of Doral Building Department issues the roof permit.

Our workHVHZ rules
What the High-Velocity Hurricane Zone means for your roof
Miami-Dade and Broward are the only two counties in the High-Velocity Hurricane Zone. In the zone, every roofing job needs a permit, including repair and maintenance. The permit application must be completed and signed by a licensed contractor, and it comes with the owner notification form and the product approval pages.
Inspections are stricter than most owners expect. For membrane roofs, the inspector looks before the attachment to the deck is covered, then again at final. Miami-Dade's Product Control Section approves roofing products, so ask each bidder for the approval number on the system they propose.
Doral's Building Department also runs a Building Recertification Program. If your building falls under it, confirm with the department what applies before you plan roof work.
Flat roof basics
Low-slope roofs, ponding water and drainage
New low-slope roofs in the zone need at least one-fourth unit of slope in 12. Loose-laid ballasted systems are not permitted at all. Where roof edges extend above the roof and could trap water, the code requires secondary overflow drains or scuppers.
Doral's median home was built in 2006, and 39.5 percent of units date from 2010 or later. By our arithmetic, that is 26 years newer than the county median of 1980. That suggests many Doral roofs are far from worn out, so a bid that calls for tear-off deserves a written reason.
A reroof in the zone must not create additional ponding water. The contractor must tell you about any ponding risk before work starts and recommend a structural review if needed. The code defines good drainage as extra slope that clears the roof within 48 hours of precipitation.
Bid checklist
How to compare commercial roofing bids
- The Miami-Dade product approval number and its expiration date for each system.
- Whether the bid is a recover or a tear-off, and why, since two prior roof layers or a wet roof bars a recover.
- Who pulls the permit with the City of Doral Building Department.
- How the bid treats existing drains, scuppers and any ponding.
- A recorded Notice of Commencement before the first inspection.
The 25% rule also matters on a multi-roof property. If more than 25 percent of a roof section is repaired or replaced in 12 months, the whole section must be redone. A roof built or redone under the 2007 code or later gets an exception for the repaired part only.
Questions
Commercial roofing in Doral: questions
Who permits a commercial roof in Doral?
Roof permits in Doral come from the City of Doral Building Department. Because Doral is in Miami-Dade County, the High-Velocity Hurricane Zone rules apply, so even a repair needs a permit and an application signed by a licensed roofing contractor. Plans attach the product approval and detail drawings. Confirm current forms and fees with the department before you sign a bid.

What is the 25% roof rule for a commercial building?
No more than 25 percent of a roof section may be repaired, replaced or recovered in any 12-month period unless the whole section is replaced or recovered. The exception covers roofs built or redone under the 2007 Florida Building Code or later, where only the repaired part must meet current code. Doral's many large multi-unit buildings should plan repairs with this limit in mind.

Can a new roof go over my existing commercial roof in Doral?
Sometimes, but not always. A recover is barred where the old roof is water soaked or too deteriorated to serve as a base, where it already has two or more roof coverings, or where it has blisters that are not cut and secured. Doral's median build year of 2006 suggests many roofs here are young enough that a recover may be possible. In the zone, a new system also may not go over sheathing that is wet, deteriorated or not fastened to code.

Do roofing products here need Miami-Dade approval?
Yes. Miami-Dade's Product Control Section approves or denies roofing systems and certifies the labs that test them. A Notice of Acceptance carries an expiration date, and a copy must be available at the job site for the Building Official. Ask each bidder for the number and check the date.
