Roof Recover Systems in Jacksonville, FL

Service

Roof recover is a legitimate scope option when the existing insulation is dry, the deck is sound, and Florida Building Code does not require a full tear-off. In Jacksonville's commercial market, recover avoids landfill disposal, reduces production time, and costs 40-60% of full replacement — when the substrate actually qualifies.

Roof recover means installing a new roofing system over the existing roof without tearing it off. The new system goes over the existing membrane, relying on the existing insulation as part of the thermal assembly. It is faster, generates less debris, costs significantly less than full replacement, and delivers a manufacturer warranty on the new system — when the project is scoped correctly.

The recover path fails when it is selected for the wrong reasons. Buildings in Jacksonville's older commercial inventory — the Baymeadows office corridor, the Near Northside industrial strip, the Riverside Avenue commercial district — frequently have BUR and modified bitumen roofs with saturation levels that make recover a poor choice. A contractor who recommends recover without running moisture assessment is either cutting corners or not capable of diagnosing the substrate. We pull moisture cores or run nuclear scanning on every roof where recover is under consideration, and we present the results in writing before the scope is finalized.

When recover is the right call, the economics are strong. A 60,000 sq ft Southside office building with sound TPO at year 18 — dry insulation, good seams, functioning drains — can receive a new TPO 60-mil recover system with a 20-year NDL manufacturer warranty for roughly half what a full replacement would cost. The building owner gets a new warranty document, eliminates the active maintenance cost of an aging membrane, and avoids two to three weeks of production disruption for tear-off. That is a genuine value, not a shortcut.

Recover Eligibility: What Qualifies and What Does Not

Dry insulation: The single most important variable. We pull five to ten moisture cores in representative locations across the roof field, at drains, at any ponding area, and at any location with prior repair history. If more than 20-25% of cores read wet, recover is off the table — the new system seals the moisture in, creating a blistering and delamination failure within two to five years and voiding the manufacturer warranty. Saturated areas can sometimes be removed and replaced in isolation, allowing a partial recover if the remainder of the roof is dry.

Deck condition: The deck must be sound and capable of accepting the additional load and fastener pullout demands of the recover system. A corroded steel deck or a deflected wood deck is a replacement condition. We inspect the deck through core pull locations and any area with visible deck deflection.

Existing membrane thickness and condition: Two layers of roofing are typically the maximum permitted by Florida Building Code before a tear-off is required. If the existing roof is already a recover — two plies already present — replacement is the only permitted option. We verify ply count on every BUR and modified bitumen recover assessment.

Florida Building Code 25% rule: If more than 25% of the total roof area has been replaced or recovered within the prior 12 months, the entire roof must be brought to current FBC requirements. Phased recover plans over multiple years can stay below this threshold with proper documentation. We advise owners on phasing strategy when the scope is close to the threshold.

Recover Systems We Install in Jacksonville

TPO recover over existing BUR or modified bitumen: The most common recover path in the Jacksonville commercial market. New 60-mil TPO is mechanically attached over the existing system using fastener patterns designed against the building's wind-uplift zone. New polyiso cover board is typically added over the existing membrane to achieve current Florida Energy Code R-value minimums and provide a stable fastening substrate. 20-year NDL manufacturer warranty is standard.
