Built-up roofing has been protecting commercial buildings for more than a century, and it remains a dependable choice for many warehouses, schools, office buildings, and other commercial properties throughout Tampa Bay. Often referred to as “tar and gravel” roofing, BUR systems are built with multiple layers of waterproofing materials. This layered construction provides added durability and helps prevent a single weak point from compromising the entire roof.
Classic Roofing & Construction provides commercial built-up roofing installation, repair, restoration, and replacement services for properties across the Tampa Bay area. With more than 20 years of commercial roofing experience, our team helps property owners evaluate the condition of their existing roof and determine the most cost-effective path forward—whether that means routine maintenance, restoration, full replacement, or transitioning to a more modern roofing system.
Our in-house crews — not subcontractors — are trained specifically in multi-ply BUR installation and repair.
A 4.8-star average backed by hundreds of real reviews, not a handful from a brand-new company.
Spread the cost of your built-up roof installation, repair, or replacement with flexible monthly payment options.
A built-up roof is constructed from alternating layers of bitumen (asphalt) and reinforcing fabrics called roofing felts or plies. Each layer bonds to the last, building a thick, continuous waterproof membrane — typically three to five plies. The system is finished with a protective surfacing:
Because the waterproofing is built up in redundant layers rather than a single sheet, BUR systems are exceptionally resistant to punctures, foot traffic, and wear — one reason they remain common on buildings with frequent rooftop equipment access.
Several plies of waterproofing mean minor surface damage rarely becomes an active leak — valuable in a region with daily summer downpours.
The thick, layered assembly handles rooftop HVAC service traffic better than most single-ply membranes.
Aggregate surfacing shields the membrane from Florida’s intense sun and provides strong fire ratings.
With routine maintenance, BUR systems commonly deliver 20–30 years of service — a track record measured in decades, not projections.
BUR isn’t the right answer for every building, and we’ll tell you when it isn’t:
TPO roofing offers a reflective, energy-efficient single-ply membrane at a lower installed weight — often the better choice when cooling costs are the priority.
Modified bitumen is BUR’s modern descendant: similar asphalt-based durability in engineered rolled sheets, often faster to install and easier to repair.
EPDM roofing provides reliable single-ply performance where budget and simplicity lead the decision.
Structural capacity is also a key factor. Because BUR is a heavier assembly, we carefully evaluate your roof deck’s load capacity and current condition before recommending it.
For replacements, we evaluate the existing assembly, insulation, and deck before recommending a system. Our crews install BUR to manufacturer specifications and Florida’s wind uplift requirements, including proper edge metal, flashings, and drainage detailing — the failure points where most flat roofs actually leak.
Blisters, alligatoring, open laps, ponding damage, and flashing failures can often be addressed through commercial flat roof repair or restoration rather than full replacement. Options such as re-flashing, targeted ply repairs, and reflective coating systems can add years of service life at a fraction of the cost of a new roof.
Commercial roofs fail slowly, then suddenly. Scheduled inspections and maintenance catch membrane wear, clogged drains, and storm damage early, protecting both the roof and your warranty coverage.
We evaluate membrane condition, drainage performance, flashing and penetration details, insulation moisture, and remaining service life, then give you a straight answer: maintain, restore, or replace.
Your written proposal outlines the recommended scope, material options, timelines, permit requirements, and cost breakdown. Florida’s commercial wind uplift codes drive attachment and edge design, and we handle that engineering documentation.
Our crews manage staging, safety, weather monitoring, and daily communication to minimize disruption to your operations with seam, flashing, and drainage inspections throughout the project.
We complete a final inspection with you and deliver warranty documentation and a maintenance plan built for your building.
Standing water and UV exposure are the two forces that age flat roofs fastest in Florida. BUR’s aggregate surfacing answers the UV problem, but drainage design does the heavy lifting against ponding — which is why our assessments always start at the drains, scuppers, and slope, not just the membrane.
With routine maintenance, most BUR systems last 20–30 years. Drainage quality, surfacing condition, and maintenance frequency are the biggest factors in reaching the high end.
BUR pricing depends on the number of plies, surfacing type, insulation requirements, deck condition, and roof access. After an inspection, we provide a written proposal with system options and a full cost breakdown.
“Tar and gravel” is the traditional name for gravel-surfaced BUR. Modern systems use refined asphalt bitumen and engineered ply sheets, with surfacing options that include mineral cap sheets and reflective coatings in addition to aggregate.
Often, yes. If the membrane is fundamentally sound, targeted repairs and a restoration coating can add years of service life. Our assessment will tell you honestly whether restoration or replacement is the better investment.
It depends on the building. BUR excels under heavy foot traffic and where multi-layer redundancy matters; TPO wins on reflectivity and installed cost; modified bitumen offers a middle path. We install all three and will recommend what fits your building — not what fits our schedule.
Whether you need commercial flat roof repair, a built-up roof assessment, or a full replacement plan, Classic Roofing & Construction gives Tampa Bay property owners clear findings and honest options.
