Best Flat & Low-Slope Roofing Contractors in Jacksonville

Flat and low-slope roofing in Jacksonville relies on membrane systems — TPO, EPDM, modified bitumen, and built-up roofing — common on commercial buildings and many modern homes. The 5 contractors below were selected from our full Jacksonville top 10 as the strongest for flat & low-slope work, ranked by experience, manufacturer certifications, BBB standing, and verified reputation.

Jacksonville is Florida's largest city by land area, and its commercial and residential spread across Duval, Clay, and St. Johns Counties creates a diverse flat-roof market. The city's position on the Atlantic coast means it sits in the hurricane impact zone but, unlike South Florida, also experiences significant winter cold fronts that produce freeze events — typically brief but capable of stressing membrane flashings and pipe penetrations that contract rapidly. This broader temperature range, compared to Miami or Tampa, means Jacksonville flat-roof systems must perform across a wider thermal span while still meeting Florida Building Code wind uplift requirements.

The northeast Florida flat-roof market is dominated by TPO for new commercial work and modified bitumen for residential and smaller commercial applications. EPDM, while common in colder northern markets, sees some use in Jacksonville's commercial sector but less than in Southeastern US peers. Florida Product Approval requirements apply to all replacement roofing materials, and the permitting process with the City of Jacksonville's Building Inspection Division is a standard requirement for any re-roofing work — a step that ensures inspections occur at the completion of work.

How do I choose a flat & low-slope roofer in Jacksonville?

Confirm licensing and insurance for Florida, ask for flat & low-slope project references in Jacksonville, get multiple written quotes, and check each contractor's BBB standing. Every company listed here has been independently researched.

Does Jacksonville require a licensed contractor for flat roof replacement?

Yes. Florida law requires that roofing work be performed by a licensed roofing contractor holding a current Florida Certified Roofing Contractor (CRC) license or a registered contractor licensed in the applicable county. The City of Jacksonville Building Inspection Division requires proof of contractor licensing at the time of permit application. Working with an unlicensed contractor on roofing work voids manufacturer warranties, creates liability exposure, and can trigger insurance coverage disputes on future claims.

How does Jacksonville's hurricane exposure affect flat roof system selection?

All re-roofing in Duval County must use Florida Product Approval-listed materials and meet Florida Building Code wind uplift requirements for the applicable wind speed design zone. Jacksonville's coastal zones have higher wind speed requirements than inland areas, and the roof-to-wall connection detail is evaluated as part of the permit inspection. For commercial buildings, the attachment method — whether fully adhered, mechanically fastened, or ballasted — must meet the calculated wind uplift pressure for the specific building height and exposure category.

What is the difference between an interior drain and a scupper on a Jacksonville flat roof?

Interior drains penetrate the roof deck at low points and connect to an internal drainage system that carries water to the building's storm sewer connection. Scuppers are openings cut through the parapet wall that allow water to drain off the roof edge into downspouts or open discharge points. Florida Building Code requires both primary drainage and overflow protection — either a secondary drain set higher than the primary or overflow scuppers — to handle extreme rainfall events without overloading the roof structure. Both systems require periodic cleaning to prevent blockage.
