Send roof plans, membrane records, repair history, current leak locations, and access constraints. We will inspect seams, flashing, drains, and attachment before setting the scope.
Product labels and old proposal notes can be incomplete. Look for membrane markings, invoices, warranty papers, drawings, repair materials, and visible seam characteristics. Carlisle offers TPO, EPDM, PVC, and fleece-backed options; two single-ply roofs may still require different cleaners, primers, adhesives, flashing pieces, and repair procedures. Record what is verified and keep uncertain areas out of the scope until they are checked.
Sure-Weld is Carlisle's heat-weldable TPO family. Sure-Seal identifies EPDM products; that membrane is joined and detailed differently from a thermoplastic sheet. Sure-Flex PVC and fleece-backed membranes add further system choices. We do not select by name alone. Roof use, exhaust, traffic, substrate, moisture, attachment, and compatibility with existing layers affect the repair or replacement decision.
For a field TPO assembly, the TPO roof review focuses on welds, laps, and compatible details. If a property has PVC, the PVC assembly review checks the right membrane and flashing transition. A different section may need a separate specification rather than a blended repair assumption. If one roof section carries a GAF EverGuard or JM single-ply system, compare its welding and flashing accessories independently; GAF thermoplastic roof details and Johns Manville membrane systems use their own product documentation.
Heat-welded thermoplastics depend on a continuous bond through the seam. Dirt, moisture, temperature, speed, pressure, or a poorly formed T-joint can leave a weak point. We inspect accessible seam edges, corners, patches, and field-to-flashing transitions. A probe can locate a separable edge, but an isolated result does not establish how far the condition extends. Mark each finding and test representative areas before widening the scope.
EPDM splices use a different approach. The seam surface and adhesive or tape condition need careful review, especially where a lap approaches a curb, drain, or prior repair. A patch that is bonded to the wrong surface or exposed edge can fail even when the surrounding sheet appears serviceable. We check material compatibility and the old repair boundary before preparing the substrate.
At a roof penetration, service work may leave a cut, loose clamp, or disturbed boot. The penetration flashing service can correct a localized transition after the water path is identified. For active interior leakage, leak investigation begins with the roof evidence rather than assuming the ceiling stain marks the entry point.
A sound membrane cannot compensate for an attachment system that no longer transfers uplift to the deck. Review fastener rows, plates, adhesive coverage, board joints, perimeter conditions, and deck type. Repeated openings or loose edges may point to a local detail or a larger assembly question. Manufacturer details help define compatible components, but a replacement design must still match the actual building and applicable project criteria.
Thermal movement can concentrate at transitions where a roof section meets a wall, curb, expansion joint, or metal edge. Check edge restraint and termination bars along with membrane condition. A wrinkle may be movement, installation geometry, or loss of bond; do not trim it before identifying the cause. Carlisle system options include adhered and mechanically attached approaches, and the selected method changes both wind transfer and substrate preparation.
Moisture below the sheet can change whether a recover remains viable. Map suspected wet insulation, make a test cut only where it will resolve a scope question, and close the opening the same day. A recover also requires review of existing layers, weight, drainage, attachment, and code conditions. The repair choice follows those findings.
After Detroit-area snowfall, inspect Carlisle seams, drains, and perimeter edges for movement or trapped debris. Snow cover can hide seams and outlets, while meltwater that remains at a low point can refreeze. Record which areas were accessible and schedule a return when the assembly can be examined safely.
Drain performance depends on more than the membrane. Check the bowl, strainer, leader, sump, overflow route, slope, and nearby insulation for signs of obstruction or movement. If an outlet is clear but water remains, verify whether the low point has changed or a downstream restriction exists. Drain and scupper work can correct a defined component defect; a wider slope or insulation issue needs a broader plan.
The city-approved Lakeside City Center concept includes housing, office, retail, dining, parks, and civic space on a former mall property. A roof review should use current drawings, inspection findings, and the approved project schedule. We schedule each inspection to the owner's actual access and construction sequence.
A local seam defect on a dry, stable assembly may need a compatible patch. Broad seam separation, deteriorated sheet, repeated moisture findings, or unstable insulation can shift the work toward a larger replacement. Fleece-backed sheets, standard membrane, EPDM, and PVC should not be treated as interchangeable at a tie-in. The scope should identify material, preparation, flashing, perimeter, drain work, test locations, and how the roof will be closed each day.
Repair schedules around occupied operations should identify rooftop unit access, delivery paths, noise restrictions, and shutdown windows. If weather interrupts installation, the daily close-in plan needs to protect exposed edges and temporary tie-ins. For buildings that remain open, occupied-building reroof sequencing can separate work areas and coordinate protection with the facilities contact.
Share Carlisle records, roof plans, leak history, old repair details, equipment access limits, and the preferred work window. We will verify the material, inspect the seam and deck transition, then define a repair or replacement scope that matches the observed condition rather than the label on a folder.
No. TPO is heat-welded, while EPDM seams and patches use different surface preparation and products. Confirm the membrane before ordering material.
It identifies a membrane with a fleece backing. Confirm the installed configuration and attachment before specifying a repair or tie-in.
Yes. Inspect the drain bowl, clamping or flashing detail, sump, leader, and nearby membrane to identify the failed transition.
Check adhesion, wet insulation, layer count, drainage, attachment, and compatibility first. A coating or recover only fits a roof that meets its system requirements.
System submittals, invoices, repair logs, warranty documents, membrane markings, and roof plans can help confirm the product and assembly.
