Data Center & Mission Critical Roofing
Single-ply membrane roofing, redundant waterproofing, and mission-critical preventive maintenance for hyperscale data centers, colocation facilities, and edge nodes across GA, TN, SC, and TX.
What this service covers.
Data centers cannot tolerate a roof leak. Capital City Roofing engineers, installs, and maintains commercial single-ply systems built to the spec sheets hyperscale GCs, colocation operators, and edge developers actually buy from - 80-mil white TPO and PVC, redundant dual-membrane assemblies, tapered polyiso to FM Global standards, and walkway pads on every service path. Our commercial division supports new construction, recoats, and 24/7 mission-critical preventive maintenance across the Atlanta, Nashville, Charleston, and Austin data center markets.
Key Benefits

How we do the work.
80-mil White TPO & PVC
Reflective single-ply membranes (solar reflectance 0.79-0.87, thermal emittance ≥0.92) that meet Energy Star, CRRC, and ANSI/SPRI cool roof requirements while resisting foot-traffic puncture from CRAC, condenser, and chiller service.
Redundant Waterproofing
Dual-membrane assemblies with secondary waterproofing layers beneath the primary membrane. The standard mission-critical detail when a single leak over a server hall is non-negotiable.
FM Global & ANSI/SPRI Compliance
Wind uplift, fire, and hail-rated assemblies installed to FM Global, UL 580/1897, and ANSI/SPRI standards required by mission-critical insurers and most hyperscale GC prequal lists.
Mission-Critical Preventive Maintenance
Bi-annual inspections, IR thermography moisture mapping, drone surveys, drain clearing, sealant and flashing service, and annual condition reporting under structured PM contracts at $0.03-$0.10/sq ft.
Why Hyperscale Data Centers Specify 80-Mil White TPO
Walk a hyperscale roof and the same spec sheet appears almost every time: 80-mil white TPO or PVC, mechanically attached or fully adhered over tapered polyiso, with a secondary waterproofing layer beneath the primary membrane and ANSI/SPRI-compliant edge details. The reasons are practical, not aesthetic. The 80-mil membrane (vs. the 60-mil typical commercial spec) handles puncture risk from rooftop technicians performing weekly CRAC, condenser, chiller, and cooling-tower service - on a strip-center roof a 60-mil membrane is fine, on a data center under monthly service traffic in Texas summer heat a 60-mil membrane will not reach eight years. The white surface delivers solar reflectance of 0.79 to 0.87 and thermal emittance of 0.92, qualifying for ENERGY STAR, the Cool Roof Rating Council, and most state cool-roof tax credits while reducing cooling load on the largest single line item in any data center's operating budget. The redundant waterproofing is the detail that separates mission-critical roofs from generic commercial roofs - a single membrane breach over a $50M server hall is not an acceptable failure mode, so the assembly is built to fail twice before water reaches a deck. Capital City Roofing installs every layer of this system to manufacturer specification and FM Global wind/uplift requirements.
Mission-Critical Preventive Maintenance: What Data Center Owners Actually Buy
Mission-critical PM contracts are not commodity service plans. A data center targeting 99.67% to 99.995% uptime cannot wait for a leak to schedule a roofer - the contract is the prevention. A typical Capital City Roofing PM program for a colocation or hyperscale facility includes bi-annual scheduled visits (spring and fall) with full visual inspection of the membrane, flashings, seams, terminations, drains, and rooftop equipment penetrations; infrared thermography across the full roof surface to identify subsurface moisture before it telegraphs through the membrane; drone surveys for high-resolution condition documentation; drain and scupper clearing; sealant and flashing service at every penetration; and an annual digital condition report with photo documentation, defect mapping, capital-planning recommendations, and warranty-compliance attestation. Pricing typically runs $0.03 to $0.10 per square foot per year depending on roof complexity, mechanical density, and reporting cadence. On a 500,000-sq-ft facility that's $15K-$50K of annual contracted revenue per building - and the contract pays back through extended roof life (10-15 years vs. the unmaintained baseline) and reduced emergency mobilization. Every visit is documented to support owner asset management and manufacturer warranty audits.
The Atlanta, Nashville, Charleston, and Austin Data Center Markets
Capital City Roofing's commercial footprint maps directly onto four of the fastest-growing data center clusters in the U.S. The Atlanta metro is now the sixth-largest market in the country by commissioned power and the fastest-growing by inventory: Switch's $2.5B 'The Keep' Tier IV Gold campus and Google's 1M+ sq ft expansion in Douglas County, the QTS 'Project Excalibur' 7M sq ft / 16-building campus and Microsoft's AI Superfactory in Fayette County, and the Prologis Project Sail $17B / 4.9M sq ft / 9-building campus approved in Coweta County in April 2026 are all inside drive distance of our Alpharetta headquarters. The Nashville corridor is anchored by Meta's Gallatin campus on its way to 1.5M sq ft and 12 data halls. The Charleston Lowcountry is anchored by Google's $1.8B Goose Creek campus and the new $3.3B Dorchester County expansion (Pine Hill in Ridgeville and Winding Woods in St. George). The Austin metro is on track to be one of the largest data center markets in the world by 2030, with Project Comal (360MW Taylor), EdgeConneX Cedar Creek (240MW), Colovore Hutto, and Blueprint Georgetown and Taylor all inside our Texas service area. We are positioned to support new construction, recoats, repairs, and PM contracts in every one of these submarkets.

For facility managers and operators evaluating a recurring service program, inside a mission-critical roof preventive maintenance program covers visit cadence, IR thermography, drone surveys, $0.03-$0.10/sf pricing, response-time SLAs, and how a structured PM contract pays back through extended roof life and emergency-call reduction.
Frequently Asked Questions
What roof system do you recommend for a hyperscale data center?
The current default for new hyperscale construction is 80-mil white TPO or PVC over tapered polyiso, with a secondary waterproofing layer beneath the primary membrane. The 80-mil thickness handles weekly tech foot traffic and dropped-tool puncture risk; the white surface meets cool roof and ENERGY STAR requirements that reduce cooling load; the redundant assembly is what mission-critical owners and their insurers buy. We adjust the spec for chemical exposure (PVC for restaurants in mixed-use facilities, modified bitumen for heavy equipment loads, etc.), but the white-TPO-with-redundancy baseline is what you'll see in 90%+ of recent data center bid sheets.
Do you do mission-critical preventive maintenance contracts?
Yes. Our PM program is built for facilities that target 99.99% uptime - bi-annual visual inspection, infrared thermography for moisture detection, drone survey, drain clearing, sealant and flashing service, and an annual condition report with capital-planning recommendations. Pricing is structured at $0.03-$0.10 per square foot per year depending on roof complexity, traffic, and reporting requirements. Most contracts run 3-5 years and include defined response-time SLAs for active leaks.
Can you work on a data center that is live and occupied?
Yes - this is most of the work. We coordinate with facility management on badged-worker access, escorted roof entry, debris-control protocols, and phased scheduling that keeps live data halls online. Our crews carry zero-debris kits, magnetic sweeps, and tool tethers as standard. We document every visit with before/after photos and digital condition logs that integrate with most owner asset management systems.
Are you on hyperscale GC prequalification lists?
We are a GAF Certified Commercial Contractor and active with the manufacturer programs - GAF, Carlisle, Firestone, Johns Manville, GenFlex - that hyperscale specs reference. We are pursuing FM Global Approval and continue adding GC prequalifications. For confirmed status with a specific GC (Holder, Brasfield & Gorrie, DPR, Skanska, Clayco, Turner, JE Dunn, McShane, Whiting-Turner, Mortenson, etc.) please contact our commercial division - prequal status is updated quarterly.
