Built-Up Roof Systems (BUR)

Roof System

Assessing Orlando's Aging BUR Stock

A BUR assessment starts with a roof walk to document visible conditions: blisters, ridging, open seams, failed flashings, drain conditions, and evidence of prior repairs. Then moisture cores — five to ten at representative locations, and more near any wet-evidence area. In Orlando's 54-inch annual rainfall environment, BUR systems on buildings without properly maintained drainage accumulate interply moisture for years before interior leaks develop. Core results determine whether the insulation is dry enough to recover or wet enough to tear off.

Gravel-surfaced BUR adds complexity to condition assessment because the gravel obscures membrane condition until you pull it back. We push gravel aside at sample points to assess the flood coat and underlying felts. Gravel ballast that has migrated to drains — common on older BUR buildings that have never had the drains cleaned — indicates a deferred maintenance history that often correlates with insulation saturation.

Downtown Orlando's mid-rise office buildings in the Lake Eola and Government District neighborhoods typically have roof access through mechanical penthouses. We document mechanical equipment conditions, curb flashing conditions, and penetration conditions on every BUR walk — because equipment curb flashings on 30-year-old BUR installations are among the most frequent active leak sources on this building type.

Transition from BUR to Single-Ply on Orlando Commercial Buildings

The most common scope on buildings with original BUR in the Orlando market is a transition to TPO or EPDM — full tear-off of the BUR system including insulation, new insulation stack designed to FBC Energy R-value requirements, and installation of the new single-ply system with FBC-compliant wind-uplift attachment.

The capital cost of the transition from BUR to single-ply is higher than a recover — demo and disposal of the old BUR system is a significant line item, and the insulation replacement adds material cost. The case for it versus recover is simple: a 20-year NDL warranty requires a new insulation stack on a sound deck. A recover over 40-year-old BUR with questionable insulation moisture history does not produce a warranted system. For buildings with active capital planning horizons of 15+ years, the transition is the right investment.

We sequence BUR-to-single-ply transitions to maintain continuous building dry-in during production — tear off in sections, install temporary dry-in at end of each day, move to the next section. In Orlando's June-October rainy season, this means daily afternoon storm monitoring and production planning. We do not leave a Downtown Orlando office building's interior exposed overnight during active rainy season.

Frequently asked questions

Is it worth repairing a 40-year-old BUR system in Orlando?

For isolated failure points on an otherwise sound system, repair extends life meaningfully. For a system with widespread interply moisture, multiple failed areas, and degraded felts throughout, repair is spending money to delay a replacement that is coming regardless. Moisture cores give us the data to make an honest recommendation — we pull them before advising on repair vs. replace.

Can you coat a BUR system to extend its life?

Yes, on a BUR system with dry insulation, sound felts, and intact flood coat. An elastomeric coating adds UV protection and can add 5-10 years of service life to a BUR system that is not yet at the end of its structural life. The coating does not work over wet insulation or failed felts — it seals moisture in rather than keeping it out. We assess the system before recommending any coating application.

What is the FBC requirement for replacing a BUR system in Orlando?

Replacement of a BUR system requires a building permit, a licensed Florida roofing contractor, and inspections at each phase. The replacement system must We manage the permit process and document FBC compliance at each phase.

Do you do BUR repairs on government buildings in Orlando?

Yes. Government-owned buildings in the City of Orlando and Orange County have the same FBC requirements as private commercial buildings. We are familiar with the procurement and documentation requirements for government building maintenance, including the scope-of-work documentation, insurance certificate requirements, and inspection coordination with government facilities staff.

Next Step

Orlando building on original BUR — what does it actually need?

Our project managers will pull moisture cores, document visible conditions, and produce a written assessment — repair scope, recover scope, or replacement scope — with capital cost band and FBC compliance documentation.
