Industrial & commercial products
Crestview Industrial supplies and sources commercial roofing materials for roofing contractors, general contractors and facility procurement teams. Our current manufacturer range includes Johns Manville, Elevate, GenFlex and Polyglass USA for membrane and accessory requirements. Coordinate the membrane, insulation, attachment and transition details as one roof-material package.
01 / The material line card
Organize the takeoff by roof area and assembly. Membrane chemistry, insulation, cover boards, attachment and edge details must follow the specified system. Brand access does not make components interchangeable or establish a warranty-qualified installation.
Match thermoplastic polyolefin membrane to the specified attachment and roof area.
Manufacturer/system, membrane thickness, roll size, roof area, attachment method, substrate and detail quantities.
Johns Manville, Elevate and GenFlex are representative TPO platforms. Exact membrane and accessories are confirmed as a compatible package.
Keep EPDM field sheet and seam materials aligned with the specified system.
System, thickness, sheet dimensions, area, attachment, seam materials and penetration details.
Johns Manville, Elevate and GenFlex provide representative EPDM families; confirm the selected configuration.
Identify the specified PVC formulation and assembly before comparing products.
Named manufacturer/model, thickness, backing, area, attachment, substrate and exposure requirements.
PVC family references are supported by Johns Manville and Elevate catalogs. Exact model availability and assembly compatibility require quotation review.
Separate base and cap layers and retain the specified application method.
Specified system, number of plies, surface/finish, application method, roof area, roll quantities and flashings.
Johns Manville and Polyglass USA provide representative SBS/APP families. Application methods are product-specific; the design and installation requirements govern.
Build the insulation takeoff from thicknesses, layers and the roof’s drainage layout.
Board dimensions, thickness, thermal requirement, layers, taper plan, slope, area and specified facer.
Johns Manville, Elevate, GenFlex and Hunter Panels support representative roof-insulation families. Confirm exact products and the complete assembly.
Specify the board independently from the insulation beneath it.
Named board, material, thickness, dimensions, area, substrate and assembly requirements.
Do not substitute cover-board materials solely on thickness. Confirm the specified product and compatibility.
Count the materials that bond or mechanically secure each layer.
Substrate/deck, selected assembly, coverage rates, container sizes, fastener type/length, spacing design and quantities.
Coverage and attachment patterns come from the applicable manufacturer and project documents; no uplift or warranty rating is implied by this list.
Measure perimeter and penetration details separately from the field membrane.
Detail drawings, membrane chemistry, dimensions, linear footage, penetrations, substrate and specified accessory models.
Use the matching system detail. Confirm sealant, flashing and substrate compatibility before order release.
Coordinate roof and wall transitions without treating every barrier as the same material.
Named system, substrate, exposure, vapor-permeance requirement, transition details, area and compatible sealants.
Exact wall-air-barrier and below-grade waterproofing access requires separate confirmation. Include these details for coordinated scope review; a roofing listing does not establish a complete wall or below-grade product range.
Separate the walking-surface layout from the membrane and insulation assembly.
Named product, layout, sizes, quantity, support heights, loading, slope and membrane protection details.
RoofBlok is a current source-supported brand; exact current paver/block models require catalog confirmation. SI Pedestal Corp. provides adjustable and stackable support references. The project design determines loading and compatibility.

Commercial roofers, general contractors and facility teams use roof plans, assembly details and specification sections to define material packages. Separate replacement, recover and new-construction areas, and identify occupied-building or phased-delivery constraints.
Separate roof zones and assemblies. Include membrane, taper, edge and penetration schedules with accessory quantities and approved alternates.
Identify existing substrates, removal/recover limits and proposed attachment. Include design-team requirements and occupied-building delivery constraints.
Provide specified systems, submittal requirements, warranty language and phasing. Organize each building or roof area as a separate takeoff.
05 / Procurement & coordination
