Flat Roofs Are a Different Specialty — And We Do Both
TPO & EPDM Flat Roofing
Flat and low-slope roofing is a fundamentally different craft than pitched-roof shingle or metal work. On a steep-slope roof, gravity does most of the work — water hits the shingles and runs off quickly. On a flat or low-slope roof, water moves slowly, collects in low spots, and sits on the membrane for hours after a rain event. The membrane must be absolutely watertight across every seam, every penetration, every edge, and every HVAC curb — because there is no gravity assist.
This is why flat roofing is a specialty. The materials are different (synthetic membranes instead of shingles), the installation techniques are different (hot-air welding, chemical adhesive, torch application), and the failure modes are different. A contractor who is excellent on pitched-roof residential work is not automatically qualified on flat-roof commercial work. Above All Roofing & Construction operates dedicated flat-roof crews trained on membrane systems.
Our flat-roof division serves commercial clients — retail centers, HOAs, warehouses, offices, churches, schools — across the Triangle and coast. We also handle the low-slope sections of residential and mixed-use buildings: rear additions, sunroom roofs, porch roofs, and other low-slope elements that need entirely different materials from the primary pitched roof above them.
TPO, EPDM & Modified Bitumen — The Right System for Every Application
Membrane Systems
Each membrane system has specific strengths and ideal applications. We walk you through all three during consultation and recommend the system that matches your building, budget, and ownership timeline.
TPO — Mechanically Attached
The most cost-effective TPO configuration. Membrane fastened to the deck with screws and plates at specified intervals. Appropriate for most standard commercial applications and the most common new commercial installation method in our market. 20–30 year manufacturer warranties.
TPO — Fully Adhered
Membrane bonded to the substrate with adhesive. Smoother finished appearance, better performance in high-wind zones. Preferred for coastal buildings and premium commercial specifications. White TPO reflects 70–80% of incident solar radiation — meaningful HVAC savings in NC's long summers.
EPDM — Fully Adhered
Synthetic rubber membrane bonded to the substrate with contact cement or low-VOC adhesive. The most common residential low-slope application method. Exceptional cold-weather flexibility, 30+ year proven service life — the longest real-world track record of any single-ply membrane.
EPDM — Mechanically Attached
EPDM membrane secured with screws and plates; seams taped with manufacturer-approved tape. Cost-effective EPDM installation for commercial and large-format applications. Available in black (standard) or white (premium, for reflectivity). 25–35 year service life with proper maintenance.
Modified Bitumen
The evolution of traditional built-up roofing. Installed in two- or three-ply systems using torch-applied heat, hot asphalt, cold adhesive, or self-adhered configurations. Particularly well-suited to high foot-traffic applications and where chemical resistance is critical. 15–20 year manufacturer warranties on certified systems.
Every Flat Roof Service We Provide
Our Services
From emergency dispatches to full replacements to restoration coatings — here is everything we handle for flat and low-slope roofs across the Triangle and coastal NC.
Full Tear-Off & Replacement
When the existing roof has reached end of life, full tear-off and replacement with modern TPO, EPDM, or modified bitumen — with upgraded insulation and code-compliant drain detail. Reroofing is the most cost-effective time to upgrade insulation, producing ongoing HVAC savings. We specify tapered insulation for proper drainage on new-slope flat roofs.
Targeted Repairs
Seam re-welding, patch repairs, flashing replacement, drain repair, HVAC curb re-detailing, membrane patching. Most targeted flat-roof repairs extend the service life of an existing roof by 5+ years at a fraction of replacement cost.
Restoration Coatings
For flat roofs that are structurally sound but nearing end of membrane service life, silicone or acrylic restoration coatings can extend the roof's life by 10+ years at a fraction of full replacement cost. We evaluate and recommend where appropriate.
Annual Maintenance Programs
Annual or semi-annual inspections including seam integrity check, drain clearing, membrane condition assessment, flashing review, HVAC curb inspection, and written condition report. Recommended for every commercial building with a flat roof.
Residential Low-Slope Sections
Many NC homes have low-slope sections over rear additions, sunrooms, porch roofs, or specific wings that require membrane roofing — not shingles. We handle these mixed-slope projects routinely, scoping flat-roof work as part of a comprehensive residential project.
Emergency Leak Response
When a flat roof fails unexpectedly — storm damage, HVAC work gone wrong, unknown pre-existing condition — our emergency team dispatches within 2–4 hours for active leak response, emergency tarping, temporary repair, and insurance documentation. On call 24/7.
Commercial Reroof & Re-Cover
When the existing commercial roof is structurally sound but the membrane is nearing end of life, a re-cover installs a new membrane over the existing one — saving 30–50% versus a full tear-off. We evaluate each building individually and recommend the right approach.
Capital Planning Inspections
For property managers and HOA boards planning ahead, we provide formal written inspection reports with estimated remaining service life, phased replacement recommendations, and budget figures for your capital-planning file. No charge for the inspection.
Warranty Registration & Closeout
Manufacturer warranty registered within 60 days. You receive warranty documentation, AARC workmanship warranty, full photo documentation, and a written condition report for your capital-planning file — all delivered at project closeout.
TPO vs. EPDM — Which System Is Right for Your Building?
TPO vs. EPDM
For most new commercial construction and reroofing projects today, we lean toward TPO because of its hot-air welded seams, white reflectivity, and chemical resistance. But EPDM has a proven 40+ year case history that TPO does not yet match — and for low-traffic, low-complexity applications where proven longevity is the primary goal, EPDM remains an excellent choice.
We walk through both options during every consultation and will recommend the system that honestly fits your building, budget, and ownership timeline — not the one with the higher margin.
TPO: Seam strength is critical
Hot-air welded seams are chemically fused — no adhesive to fail over time.
TPO: Reflectivity matters
White TPO reflects 70–80% of solar radiation — meaningful HVAC savings in NC's long summers.
TPO: Chemical resistance needed
HVAC grease, oils, industrial exhaust — TPO holds up against the widest range of exposures.
EPDM: Proven long-term track record
40+ year real-world case histories exist — no equivalent yet for TPO's newer track record.
EPDM: Cold-weather flexibility
EPDM remains flexible at temperatures well below what TPO handles — important in NC's occasional freezes.
EPDM: Lower installed cost
Mechanically attached EPDM is typically the lowest-cost single-ply option in our market.
Modified bitumen: Heavy foot traffic
High-traffic applications, chemical resistance, or granulated-surface aesthetic — mod bit is the right call.
Transparent Flat Roof Pricing — Line-Item on Every Project
Flat Roofing Pricing in NC
Flat roofing is priced per square foot, not per roof-square. The right membrane system for your building depends on slope, deck type, wind zone, insulation goals, and ownership timeline. We provide every client with a written, line-item scope and pricing document — and in most cases comparative proposals across multiple systems so you can make the best decision for your building.
Pricing ranges: TPO mechanically attached $6.50–$9.50/sf · TPO fully adhered $8.00–$12.00/sf · EPDM fully adhered $5.50–$8.50/sf · Modified bitumen 2-ply $6.50–$9.50/sf · Restoration coating $2.50–$5.00/sf · Insulation upgrade adds $1.50–$3.50/sf · Re-cover saves 30–50% vs. tear-off

Flat Roofing FAQ
Frequently Asked Questions
How long does a flat roof last?
TPO: 20–30 years with maintenance. EPDM: 25–35 years with maintenance. Modified bitumen: 15–20 years. All of these can be extended 5–10 years with restoration coatings applied before end of service life — often the highest-ROI maintenance investment on a commercial building.
Do flat roofs always leak?
No — this is a persistent myth from the era of built-up roofing when leak rates were legitimately higher. Modern TPO and EPDM systems, properly installed with proper drainage, are highly watertight for their full service life. Problems arise from improper installation, deferred maintenance, or mechanical damage — not from the membrane being inherently leak-prone.
Can you handle the low-slope sections on my residential home?
Yes. Many NC homes have low-slope sections over rear additions, porches, or sunrooms that require membrane roofing rather than shingles. We handle these mixed-slope projects routinely, typically scoping the flat-roof work as part of a comprehensive residential project so that warranties align and one contractor is responsible for the entire roof system.
How quickly can you respond to an emergency flat roof leak?
Our commercial emergency team dispatches within 2–4 hours for active leak situations, 24/7. We provide emergency tarping, temporary repair, and full damage documentation for insurance claims while the permanent repair or replacement is being scoped and scheduled.
Do I need insulation upgrades when I reroof?
In most cases, yes — modern code requires R-values that were not required on older buildings, and reroofing is typically the most cost-effective time to upgrade. Tapered insulation also improves drainage on flat roofs, which extends membrane service life. We specify insulation upgrades on every reroof scope and include the cost as a clear line item.
Will a new TPO roof qualify for Energy Star or tax credits?
White TPO installations typically qualify for Energy Star Cool Roof designation and may qualify for federal or state energy-efficiency tax credits depending on your jurisdiction and tax situation. We provide spec documentation on request for every project.
