In the wake of the Champlain Towers South collapse in Surfside, Florida, the state legislature passed Senate Bill 4-D in 2022, establishing mandatory milestone structural inspections for condominium and cooperative buildings. These inspections represent the most significant change to Florida building safety requirements in decades, and the roof is one of the critical structural components that must pass.
If you serve on a condo board, manage a condominium property, or own a unit in a building that is approaching its inspection deadline, understanding the roof requirements is essential. Failing the roof component of a milestone inspection triggers mandatory remediation — and the costs, timelines, and consequences are not something any board wants to navigate unprepared.
What SB 4-D Requires
Senate Bill 4-D, codified in Florida Statutes Section 553.899, establishes mandatory milestone structural inspections for certain buildings. Here is exactly what the law requires.
Which buildings are covered. The law applies to condominium buildings and cooperative buildings that are three stories or taller. Single-family homes, duplexes, and low-rise buildings under three stories are not subject to milestone inspection requirements. The three-story threshold is measured from ground level to the highest occupied floor — parking levels below grade may or may not count depending on local interpretation.
When inspections are required. Buildings located within three miles of the coastline must complete their initial milestone inspection when the building reaches 25 years of age based on the certificate of occupancy date. Buildings located more than three miles from the coastline must complete their initial inspection at 30 years. After the initial inspection, subsequent inspections are required every 10 years.
Compliance deadlines. Buildings that had already reached 30 years of age (or 25 years for coastal buildings) when SB 4-D took effect were given until December 31, 2024, to complete their initial milestone inspection. Buildings approaching the threshold must complete the inspection by the applicable deadline based on their certificate of occupancy date.
Who performs the inspection. Milestone inspections must be performed by a licensed professional engineer or a licensed architect. The inspector must be licensed in the State of Florida and qualified to perform structural assessments. The condo association selects and hires the inspector, but the inspector's professional duty is to the public safety — not to the association.
The Two-Phase Inspection Process
Milestone inspections follow a two-phase structure designed to identify structural problems efficiently without unnecessary invasive testing.
Phase one: visual examination. The phase one inspection is a visual examination of the building's major structural components. The inspector walks through the building, examines accessible structural elements, and looks for visible signs of deterioration, distress, or failure. For the roof, the phase one inspection typically includes visual assessment of the roof covering condition — looking for missing, cracked, lifted, or deteriorated roofing material. The inspector examines visible structural elements such as roof trusses, rafters, decking, and support beams that are accessible from attic spaces or mechanical rooms. They check for signs of water intrusion including staining, mold, or rot in the roof deck and structural members. Drainage systems are evaluated, including gutters, scuppers, internal drains, and roof slope adequacy. The inspector assesses flashing condition at penetrations, edges, walls, and transitions. For flat commercial roofs, they check for ponding water — standing water that remains more than 48 hours after rainfall.
If the phase one inspection finds no evidence of substantial structural deterioration, the inspection is complete. The inspector issues a report confirming that the building passed phase one, and no further action is required until the next 10-year inspection.
Phase two: detailed investigation. If the phase one inspection reveals signs of substantial structural deterioration in any component — including the roof — a phase two inspection is required. Phase two involves more detailed and potentially invasive testing to determine the extent and severity of the deterioration.
For roof systems, phase two testing may include core samples of the roof assembly to evaluate moisture content and structural integrity of each layer. The inspector may perform infrared moisture surveys to map moisture intrusion patterns across the entire roof area. Structural load testing may be performed to determine whether the roof structure can still support required loads, including the weight of the roofing material, live loads from maintenance personnel, and wind uplift forces. The inspector may remove sections of the roof covering to examine the underlayment and deck condition directly.
The phase two report provides detailed findings, identifies the specific structural deficiencies, and may include recommendations for remediation.
The Roof Component: What Inspectors Evaluate
The roof is one of the most critical components in a milestone inspection because it serves as the building's primary barrier against Florida's extreme weather. Here is what inspectors focus on.
Structural integrity of the roof framing. The inspector evaluates the condition of roof trusses, rafters, joists, and other structural framing members. They look for signs of wood rot, termite damage, steel corrosion, cracking, deflection beyond acceptable limits, and any modifications or alterations that may have compromised structural capacity. In older concrete and steel buildings, the inspector checks for spalling concrete — where the surface layer of concrete breaks away, exposing reinforcing steel to corrosion.
Roof deck condition. The roof deck — the surface to which roofing material is attached — must be structurally sound. For wood decks, the inspector checks for rot, delamination, and fastener withdrawal. For concrete decks, they evaluate for cracking, spalling, and reinforcement corrosion. A deteriorated roof deck compromises the wind uplift resistance of the entire roof system, which is a critical safety concern in hurricane-prone Florida.
Remaining useful life. The inspector assesses the remaining useful life of the roof system. A roof that is technically functional today but approaching the end of its expected lifespan may be flagged as a concern in the inspection report, particularly if the building's reserve study does not include adequate funding for near-term replacement.
Wind resistance. Florida Building Code requires specific wind resistance ratings for roof systems based on the building's location and exposure category. The inspector evaluates whether the existing roof system meets current wind resistance requirements. Older buildings that were constructed under previous building codes may have roof systems that fall short of current wind rating requirements — this is particularly relevant for buildings in the High Velocity Hurricane Zone covering Miami-Dade and Broward counties.
Water intrusion. Any evidence of water intrusion through the roof system — staining on interior ceilings, mold growth in attic spaces, moisture in roof insulation — indicates a roof system failure that will be documented in the inspection report. Chronic water intrusion can cause progressive structural deterioration of the roof deck and framing.
Drainage adequacy. The inspector evaluates whether the roof drainage system — including internal drains, scuppers, gutters, and roof slope — adequately removes water from the roof surface. Ponding water on flat roofs adds weight that the structure may not be designed to support and accelerates deterioration of the roof membrane and deck.
What Happens If Your Roof Fails
If the milestone inspection identifies substantial structural deterioration in the roof system, the consequences follow a defined sequence.
Phase two investigation. If the phase one visual inspection reveals concerns, a phase two detailed investigation is ordered. This investigation involves testing and analysis that is more invasive and expensive than the visual inspection — typically $10,000 to $50,000 depending on the building size and scope of testing required.
Remediation plan required. Once the phase two report confirms structural deficiencies, the condo association must develop a remediation plan. This plan must be prepared by a licensed engineer, must address all identified deficiencies, and must include a timeline for completion. The plan is submitted to the local building official for review and approval.
Mandatory timeline. The local building official sets a timeline for completing the remediation. While SB 4-D does not specify exact remediation timelines — leaving them to local authority — building officials typically require remediation to begin within 180 days and be completed within a timeframe that reflects the severity of the deficiencies. Critical structural deficiencies may require emergency remediation on an accelerated timeline.
Funding requirements. The remediation must be funded by the condo association, which typically means either drawing from reserves or levying a special assessment on unit owners. Under the related reserve funding requirements that also changed in 2022, condo associations can no longer waive or reduce reserves for structural components including the roof. This means associations should already be building reserves for roof replacement — but many older associations have decades of deferred reserve funding that left them underprepared.
Unsafe building declaration. In extreme cases, if the inspection reveals structural deterioration that poses an immediate threat to life safety, the local building official can declare the building unsafe for occupancy. Residents may be ordered to evacuate until remediation is completed. This is the worst-case scenario and underscores why proactive roof maintenance and timely replacement are so critical.
How Boards Should Prepare
Condo boards that wait until the milestone inspection deadline to think about their roof are setting themselves up for expensive surprises. Proactive preparation is far less costly and stressful than reactive remediation under a regulatory timeline. Here is what smart boards are doing.
Get an independent roof assessment now. Hire a licensed roofing contractor to perform a comprehensive roof condition assessment separate from the milestone inspection. This assessment evaluates the remaining useful life of the roof, identifies any current deficiencies, and provides a replacement cost estimate. Having this information two to three years before the milestone inspection gives the board time to plan and budget.
Update the reserve study. Florida law now requires condo associations to include fully funded reserves for structural components, including the roof. Update your reserve study to reflect current roof replacement costs — not the costs from five or ten years ago. In South Florida, a commercial roof replacement for a multi-story condo building can cost $200,000 to $1,000,000 or more depending on the building's size, height, and access complexity.
Address known issues proactively. If you know the roof has problems — active leaks, deteriorated flashing, ponding water, visible membrane damage — address them now rather than waiting for the milestone inspection to document them. Proactive repairs demonstrate that the board is maintaining the building responsibly and may prevent minor issues from escalating into substantial structural deterioration findings during the inspection.
Budget for remediation contingency. Even if you believe the roof is in good condition, budget for the possibility that the milestone inspection identifies issues requiring remediation. Setting aside contingency funds now prevents the need for emergency special assessments if unexpected problems are found.
Compile maintenance documentation. Gather all records of roof maintenance, repairs, and inspections performed over the building's life. This documentation provides context for the milestone inspector and demonstrates a history of responsible maintenance. Inspectors view well-documented maintenance histories favorably because they indicate that the association has been monitoring the roof's condition over time.
Consider proactive replacement. If the roof is within five years of the end of its expected lifespan, proactive replacement before the milestone inspection may be the smartest financial move. Replacing the roof on your own timeline allows the board to competitively bid the project, select optimal materials, and schedule work during favorable conditions. Replacing under a mandatory remediation timeline often means compressed schedules, limited contractor options, and premium pricing.
Reserve Study Implications
The reserve funding changes that accompanied SB 4-D have significant implications for roof budgeting. Associations can no longer vote to waive or reduce reserves for structural components. This means every condo association must be setting aside funds for eventual roof replacement based on the roof's expected lifespan and current replacement cost.
For a building with a roof that costs $500,000 to replace and has a 25-year expected lifespan, the annual reserve contribution for the roof alone should be approximately $20,000 per year. Many older associations that historically waived reserves are now scrambling to build up reserve balances, often requiring significant increases in monthly assessments.
Boards that address roof replacement proactively — replacing the roof before it fails the milestone inspection — can plan the reserve buildup over a longer period, resulting in smaller annual increases. Boards that wait for a failure finding face compressed timelines that may require large special assessments.

Frequently Asked Questions
What is a milestone inspection under Florida's SB 4-D?
A milestone inspection is a structural inspection required by Florida Senate Bill 4-D, which was passed in 2022 following the Champlain Towers South collapse in Surfside. The law requires condominium buildings and cooperative buildings that are three stories or taller to undergo a phase one structural inspection when the building reaches 30 years of age, or 25 years if the building is within three miles of the coastline. The phase one inspection is a visual examination of the building's structural components, including the roof structure, load-bearing walls, floors, foundation, and other primary structural elements. If the phase one inspection reveals substantial structural deterioration, a phase two inspection is required, which involves more detailed and potentially invasive testing. The inspection must be performed by a licensed engineer or architect. After the initial milestone inspection, subsequent inspections are required every 10 years. The law applies to buildings with certificates of occupancy issued on or before July 1, 1992, for the initial compliance deadline.
What happens if a condo roof fails the milestone inspection?
If the roof component of a milestone inspection reveals substantial structural deterioration, the building enters a mandatory remediation process. The inspecting engineer or architect will document the specific deficiencies in their phase one report. If the issues are significant enough to warrant a phase two inspection, the engineer will conduct more detailed testing — which may include core samples, moisture surveys, and structural load analysis of the roof system. Once the phase two report is complete, the condo association must develop a remediation plan that addresses all identified structural deficiencies within a timeline specified by the local building official. Failure to complete required remediation can result in the building being declared unsafe for occupancy. For roof-specific failures, common remediation requirements include replacing the roof covering and underlayment, repairing or replacing deteriorated roof decking, reinforcing roof-to-wall connections, addressing ponding water issues on flat roofs, and upgrading the roof system to meet current Florida Building Code wind resistance requirements. The association board is responsible for funding and executing the remediation, typically through reserves or special assessments.
How should a condo board prepare their roof for a milestone inspection?
Condo boards should begin preparing for their milestone inspection at least two to three years before the deadline. Start with an independent roof condition assessment by a licensed roofing contractor — separate from the milestone inspection itself — to identify any issues that should be addressed proactively. Review the building's roof maintenance history and compile documentation of all repairs, replacements, and inspections performed on the roof. Ensure the roof access points are safe and accessible for the inspecting engineer. Budget for potential remediation by updating the reserve study to include roof replacement costs based on current pricing. If the roof is approaching the end of its expected lifespan, consider proactive replacement before the milestone inspection rather than waiting for a failure finding that triggers mandatory remediation under a compressed timeline. Address any known drainage issues, flashing failures, or visible deterioration before the inspection. Having a recent professional roof assessment report available for the milestone inspector demonstrates that the board has been proactively maintaining the building and can provide context for the inspector's evaluation.
