Flat Roof Systems We Maintain

Commercial flat roofing encompasses a diverse range of sophisticated systems, each with unique material compositions, installation methodologies, and specific maintenance requirements. Our certified technicians are proficient in the comprehensive care of all major flat roof types, ensuring optimal performance and extended service life.

• TPO and EPDM Single-Ply Membranes: Thermoplastic Polyolefin (TPO) and Ethylene Propylene Diene Monomer (EPDM) are widely utilized single-ply roofing systems known for their durability and flexibility. TPO, a heat-welded membrane, offers superior puncture resistance and UV stability. EPDM, a synthetic rubber, is celebrated for its longevity and resistance to extreme temperatures. Both systems require meticulous, regular seam inspection to detect any signs of delamination, especially at flashing details and parapet walls. We vigilantly watch for membrane shrinkage, which can lead to stress on seams and fasteners, and proactively address fastener backing out or membrane uplift. Ponding water, a common issue, significantly accelerates the degradation of these membranes, leading to premature failure. Our maintenance protocols include comprehensive assessments of membrane integrity, sealant condition around penetrations, and proper adhesion.
• Modified Bitumen (Mod-Bit): An asphalt-based system enhanced with polymer modifiers (SBS for flexibility at low temperatures, APP for plasticity and UV resistance), Modified Bitumen offers exceptional resilience. These multi-ply systems, often installed via torch-application, self-adhesion, or hot-mopping, require regular coating applications to prevent the asphaltic layers from becoming brittle, cracking, or "alligatoring" under intense UV exposure and thermal cycling. Our inspections focus on identifying blisters, interply separation, and granule loss on mineral-surfaced membranes, which indicate surface erosion and diminished UV protection. Proactive coating with reflective elastomeric or asphaltic coatings is crucial for extending the lifespan of Mod-Bit roofs.
• Built-Up Roofing (BUR): The original flat roofing system, Built-Up Roofing (BUR) consists of multiple layers of bitumen (asphalt or coal tar) alternated with plies of reinforcing fabrics (felts), typically surfaced with gravel or a reflective coating. Gravel-covered BUR systems require diligent checking for bare spots in the gravel aggregate, which expose the underlying felts to damaging UV radiation. We also ensure that gravel is not accumulating in drains or scuppers, which can lead to ponding and block proper water evacuation. Our maintenance identifies mat deterioration, interply delamination, and blistering, which are common failure modes in aging BUR systems.
• Other Advanced Systems: Proof Construction also possesses extensive expertise in maintaining other sophisticated commercial flat roof systems, including PVC membranes (known for chemical resistance and weldability), and advanced liquid-applied roofing systems (such as PMMA or urethane coatings) that offer seamless, self-flashing solutions for complex roof geometries and restoration projects. Each system demands a tailored maintenance approach that our experts are equipped to provide.

Comprehensive Maintenance Schedule

A robust, regularly scheduled maintenance program is the cornerstone of flat roof longevity and compliance with manufacturer warranties. Our schedule is meticulously designed to preempt issues and mitigate risks.

• Monthly Visual Inspection from Ground: Our technicians conduct a thorough visual assessment from the ground level to identify immediate concerns such as obvious debris accumulation, displaced coping, or initial signs of ponding. This initial check is vital for early detection of potential problems without disturbing the roof surface.
• Check for Ponding Water: Any water that remains on the roof surface for more than 48 hours is considered ponding and is a severe threat to all flat roof systems. Ponding water accelerates membrane degradation, promotes biological growth, increases hydrostatic pressure on seams and flashings, and can void manufacturer warranties. We identify the causes, whether due to inadequate slope, structural settling, or clogged drainage, and recommend appropriate corrective actions such as drain cleaning, adding crickets, or tapered insulation.
• Clear Debris from Roof Surface: Organic debris (leaves, branches) and inorganic debris (trash, construction materials) can clog drainage systems, create puncture hazards, and promote vegetative growth that can compromise the membrane. Regular removal is essential.
• Check Drains and Gutters: Ensuring unimpeded flow through internal drains, scuppers, and external gutters is paramount to prevent water accumulation. We meticulously clear blockages and inspect drain baskets and strainers.
• Quarterly Full Walkover Inspection: Our certified roof inspectors conduct a comprehensive, on-membrane walkover inspection, meticulously examining every square foot of your flat roof.
• Check Flashing and Parapet Caps: The vast majority of commercial flat roof leaks originate at critical transition points such as flashing details around penetrations, parapet walls, and equipment curbs. We inspect base flashings, counter flashings, and coping caps for integrity, signs of dislodgement, or sealant failure.
• Inspect Sealants and Caulking: Exposed sealants and caulking around skylights, HVAC units, and other penetrations are prone to degradation from UV radiation and thermal cycling. We identify cracked, dried, or missing sealants and recommend prompt resealing to maintain watertight integrity.
• Document Condition for Warranty: Detailed documentation, including photographic evidence and written reports, is maintained for every inspection. This not only supports warranty compliance but also provides a historical record of your roof's condition and maintenance activities, invaluable for insurance claims or future repairs.
• Annually Professional Inspection with Detailed Report: Our annual professional inspection is a comprehensive deep dive into your roof's health, performed by our most experienced commercial roofing specialists. This includes a detailed report outlining all findings, recommended repairs, and photographic evidence.
• Thermal Imaging to Detect Moisture: Utilizing state-of-the-art infrared thermography, we can non-invasively detect trapped moisture within the roof assembly. This advanced technique pinpoints saturated insulation or subsurface leaks that are invisible to the naked eye, allowing for targeted, cost-effective repairs rather than extensive tear-offs.
• Preventative Maintenance Visit: This visit includes proactive measures such as minor patch repairs, sealant touch-ups, drain cleaning, and addressing any emerging issues identified during inspections before they escalate into major problems.
• Update Maintenance Records: All inspection reports, repair logs, and thermal imaging data are meticulously updated in your building's maintenance records, providing a transparent, auditable history of your roof’s care.

Common Problems & Tulsa's Unique Challenges

Commercial flat roofs in Tulsa face a unique set of challenges posed by Green Country's volatile climate, from scorching summers with intense UV radiation to freezing winters and severe storm activity.

• Ponding Water: Beyond poor initial design or structural settling, persistent ponding in Tulsa can be exacerbated by sudden, heavy downpours that overwhelm drainage systems. The freeze-thaw cycles common in Oklahoma can turn ponded water into ice, causing significant stress and damage to the membrane and underlying structure. Our solutions include optimizing drainage, installing tapered insulation systems, or adding crickets to direct water flow.
• Flashing Failures: Given Tulsa's high wind zones and frequent severe weather, flashing failures are a leading cause of leaks. Improperly secured or deteriorated flashing at roof edges, parapet walls, and around rooftop equipment (HVAC, vents, skylights) is highly susceptible to wind uplift and water intrusion. Proof Construction adheres strictly to IBC/IRC and Oklahoma-specific building codes for proper flashing installation and maintenance, ensuring maximum wind resistance.
• Membrane Damage: The intense UV radiation in Oklahoma accelerates the degradation of all roofing membranes. Furthermore, hail storms, a common occurrence in Tulsa (often categorized by NOAA as severe when diameters exceed 1 inch), can cause significant impact damage, leading to punctures, bruising, or granule loss on modified bitumen roofs. High winds can cause membrane uplift, tearing, or scour damage from airborne debris. Foot traffic from maintenance personnel or other trades can also cause mechanical damage. Prompt repair of even minor membrane damage is critical to prevent water intrusion and progressive deterioration.
