Sika Sarnafil Commercial Roofing
A PVC repair scope depends on the membrane installed at the roof. We inspect the area, identify the product from field markings and available records, and match the repair detail to the existing assembly before choosing cleaning, welding or flashing materials. The University of Georgia Athens campus contains a mix of academic, residential and support uses; a roof on an occupied Athens campus has its own access needs. A business near Beechwood-Alps commercial area has a different operating route. We plan to the actual building.
Identify the Sarnafil membrane
Sika Sarnafil commercial roofing includes PVC membrane systems. We verify the installed product, reinforcement and attachment from field details and records rather than assuming every PVC roof has the same construction. Membrane thickness, seam method, flashing and accessories depend on the specification. If the system cannot be confirmed, the report identifies which submittal or test is needed before a repair material is ordered.
Thermoplastic seams are joined with heat, which means surface condition, preparation and welding settings matter. We inspect the seam for contamination, surface wear, open laps and prior repairs, then check the connection using the procedure appropriate to the system. A PVC assembly has different repair chemistry from TPO, even if both use welded seams. Approved project documents control the product and field detail.
Prepare the membrane before a weld
We clean and prepare the repair area according to the system requirements, removing loose material and checking whether the membrane remains suitable for a new connection. If the surface is wet, brittle or contaminated, a weld may not bond as intended. The scope identifies preparation, test welds where required, patch dimensions and edge treatment. A repair that crosses a seam, curb or change of plane needs compatible flashing details rather than a flat patch alone.
At drains, parapets, penetrations and rooftop equipment, we inspect the transition, termination and underlying support. A roof inspection documents conditions before the repair boundary is set. The building contact confirms whether equipment can be shut down, and we record service clearance before working around a unit.
For a PVC membrane detail, the surface must be clean and prepared for the approved weld or repair accessory. We identify contamination, prior coatings, aged material and any patch that could affect the new connection. A representative test weld helps confirm tool settings under the actual field conditions, and the completed seam is probed after cooling. Corners, drains and curbs are inspected as separate details because they require formed flashing pieces and careful terminations. The owner’s roof map should show where repair work ends and untouched material begins.
Check deck, insulation and water entry
A PVC membrane can look intact at the field while moisture or separation sits beneath it. We compare interior reports with roof slopes, seams, penetrations and drains. When concealed layers may affect the repair, we mark a test area and state how the result changes the boundary. A drain review can guide investigation, while a sample confirms what is below. Wet insulation or a failing deck requires attention before the finished membrane closes the area.
Athens’ warm-season thunderstorms and humid summer weather make prompt dry-in planning useful after an opening is found. We map how much roof can be exposed, stage compatible material and set the end-of-shift tie-in. For a property along the Lexington Road corridor, deliveries and business traffic may shape the access window. Campus facilities near UGA have their own routes and hours, confirmed with the site contact.
Follow the PVC detail through the perimeter
Installation includes substrate preparation, specified insulation or cover board, membrane placement, seams and edge terminations. We check weld continuity and complete flashing at walls, curbs, drains and penetrations with details compatible with the system. If a roof transition differs from the drawing, we document the condition and obtain direction before changing the assembly. The crew identifies each phase, protects the tie-in overnight and photographs the completed area before moving on.
The approved specification determines attachment, accessory selection and the exact membrane configuration. We keep materials from other manufacturers out of the system unless an approved detail allows them. A cover board scope or equipment curb plan can coordinate substrate and rooftop details. Those scopes are coordinated before membrane work so another trade does not leave an open curb or unsupported transition in a finished section.
After a field weld, the repair lead checks continuity across the full patch edge and inspects any nearby change in plane. We record the test procedure and conditions during installation so the closeout has context if a later visit examines the same detail. When access or weather prevents a complete check, the record identifies that limit and schedules the needed follow-up rather than marking the work area without qualification.
Compare repair with broader restoration
For an isolated puncture, open lap or damaged flashing, we inspect the surrounding membrane and prepare a compatible repair. If repeated splits, widespread surface damage or wet insulation are found, we map the larger area and compare localized patching with restoration or replacement. An urgent response identifies the specific defect; a coating review is considered only when the assembly is dry, bonded and suitable for the selected coating.
If the existing layer is not suitable to remain, a replacement scope defines removal, substrate work and the new detail set. We explain cost and schedule drivers, including access, equipment lifts, drainage and occupied-space controls. A Carlisle SynTec or Johns Manville assembly is a different product system and cannot be patched as though it were the identified Sarnafil roof. We keep each building’s product record precise.
Record the membrane and repair map
Turnover includes roof zones completed, photos of field seams and transitions, drains and open items that need follow-up. We record system details available from approved submittals and tie repairs to the roof map. If a test was not completed or an area remained inaccessible, that limitation is listed. Facilities can then use the closeout when scheduling service or reviewing future equipment work.
For occupied properties in Athens, the work route, material staging and daily cleanup are included in the closeout record if they affected operations. We inspect safely and separate temporary protection from permanent repair. Contact Commercial Roofing Athens to review a Sika Sarnafil roof, verify its installed detail and plan a repair or project sequence.
Adjacent PVC seams can be stressed by equipment vibration or repeated foot traffic. Check the membrane along those access routes after mechanical servicing, and add a walkway pad where the selected system calls for traffic protection.

Frequently Asked Questions
Can you repair a Sika Sarnafil PVC roof?
We can inspect the installed product and prepare a compatible repair detail. The field scope defines surface preparation, welding, flashing and any test needed below the membrane.
Is any hot-air weld acceptable for PVC?
No. Surface preparation, settings and technique must match the membrane and conditions. We verify the applicable system detail and check the completed seam.
What if the PVC is dirty or weathered?
We evaluate whether the surface can be cleaned and welded, or whether the affected material must be removed. A test area can answer that before the full repair begins.
Can a PVC roof be coated?
A coating is considered only after the assembly and surface are confirmed suitable. Moisture, loose membrane or failing transitions need correction before a new coating is applied.
What is included in the installation record?
We provide mapped work areas, photos, available submittal references, inspected transitions and remaining items for the property file.
