Multi-Building Roofing Claims Guide

• →Multiple structures — apartment complexes, hotels, office parks, industrial campuses, schools, and churches each contain distinct buildings requiring separate documentation tracks, not one aggregated photo folder.
• →Large claim values — total insured values multiply across structures, triggering specialist adjusters, engineer review, statistical sampling protocols, and extended desk-review cycles.
• →Increased carrier scrutiny — carriers apply representative sampling, spot-repair arguments, and partial-replacement limits more aggressively when claim values exceed single-structure thresholds.
• →Sampling disputes — desk reviewers may approve scope on sampled buildings while denying identical damage on unsampled structures; building-level indexing defeats statistical shortcuts.
• →Consistency challenges — construction differences, roof system variety, and varying ages across buildings require standardized documentation formats applied uniformly despite field variation.
• →Extensive documentation requirements — carriers expect site maps, building inventories, per-structure photo indexes, and measurement reconciliation beyond single-home residential templates.
• →Project logistics — staging, crane setup, material delivery, debris removal, and tenant coordination vary by building and must be documented to support estimate line items.
• →Phased claim handling — partial approvals, building-by-building production, and progressive supplements require contemporaneous logs that tie each phase to indexed field evidence.

• →Building numbering — adopt property management's official numbering scheme; mismatched labels between contractor files and owner records delay carrier and production review.
• →Site maps — publish a labeled site plan showing every building, elevation orientation, parking structures, and detached amenities before detailed close-up documentation.
• →Roof identification — assign each roof plane a unique identifier tied to building ID and elevation; multi-level and cut-up geometry requires slope-level labels on the site map.
• →Building classifications — categorize structures by use (residential units, amenity, office, warehouse, parking) and construction type to support scope attribution and carrier review.
• →Construction differences — document varying roof pitches, heights, access points, and assembly types across buildings; carriers cannot apply single-structure assumptions to mixed portfolios.
• →Roofing system inventory — record assembly type, manufacturer, approximate age, and layer count per building before peril-specific documentation begins.
• →Drone overviews — capture aerial context for campus layouts, inaccessible slopes, shared drainage paths, and building-to-building relationships when permitted and safe.
• →GIS and site plans — attach property-provided GIS exports, as-built drawings, or survey plans when available; reconcile field findings to official site geometry.

See the HOA Roofing Claims Guide when the property is a community association with governing documents and board approval requirements.

• →Inspection sequencing — complete building inventory before field work; schedule inspections in logical campus zones to maintain consistent crew documentation standards.
• →Drone documentation — capture campus overviews, roof plane relationships, and inaccessible areas before ground and roof-level close-ups.
• →Ground photography — photograph every building elevation from ground level with overview shots showing building ID labels before ascending to roof level.
• →Roof photography — overview and close-up pairs for every elevation on every building; never mix Building 3 damage into Building 7 folders.
• →Test squares — perform hail test squares per building on storm losses; record square location, impact count, and functional damage findings indexed to building ID.
• →Moisture surveys — conduct infrared or nuclear moisture scans on low-slope assemblies per building when wet insulation is suspected; see Commercial Roofing Documentation Guide for membrane protocols.
• →Interior inspections — correlate ceiling stains, attic decking, and top-floor unit damage to roof zones above; interior maps support water intrusion documentation.
• →Safety planning — document fall protection, roof access hazards, and crew safety plans before mobilizing across structures with varying heights and pitches.
• →Access coordination — log property authorization, tenant notification, escort requirements, gate codes, and restricted areas before each inspection day.
• →Consistent documentation standards — apply the same naming convention, photo pairing rules, and elevation labeling across every structure regardless of roof type or damage severity.

See the Hail and Wind Damage Roof Documentation Guides for peril-specific field evidence standards on storm losses.

• →Wind damage — document creased tabs, broken seals, lifted edges, and directional patterns per building and elevation; see Wind Damage Roof Documentation Guide.
• →Hail damage — record impact patterns, test square results, soft metal collateral, and functional damage per building; see Hail Damage Roof Documentation Guide.
• →Mechanical damage — photograph HVAC maintenance damage, foot traffic wear, and equipment impact separate from storm-created conditions to support attribution.
• →Water intrusion — correlate interior ceiling maps to roof zones; document ponding, drain blockages, and membrane breaches on low-slope sections.
• →Flashings — capture wall, chimney, skylight, parapet, and penetration flashings per building with overview pairs showing location on the elevation.
• →Ridge components — photograph ridge caps, hips, and ridge ventilation per building with damage indexed to specific linear footage.
• →Valleys — document open and closed valley conditions, debris accumulation, and impact damage with building-specific measurement references.
• →Gutters and downspouts — photograph length, slope, separation, and impact damage; document shared drainage runs spanning multiple buildings on the site map.
• →Roof penetrations — pipe boots, vents, skylights, and exhaust fans photographed per building with overview and close-up pairs.
• →HVAC equipment — document roof-mounted units, curbs, refrigerant lines, and detach-reset requirements per building; equipment inventory varies across campuses.
• →Detached structures — garages, sheds, carports, mail kiosks, and storage buildings each receive building IDs and independent photo sets.
• →Accessory buildings — pool houses, clubhouses, maintenance buildings, and gate structures treated as distinct indexed structures, not merged into nearest building folders.
• →Standardized documentation — apply identical photo organization, naming convention, and elevation coverage rules to every structure regardless of damage severity or roof type.

• →Representative sampling disputes — when carriers sample a subset of buildings, document identical damage on unsampled structures with the same photo standards and test square methodology.
• →Spot repair arguments — photograph repairability test results, collateral damage potential, and manufacturer patch limits per building; see Roof Repairability Documentation Guide.
• →Partial replacement disputes — build per-building scope tables showing why partial repairs fail matching, repairability, or code compliance on specific structures.
• →Matching across buildings — document color, profile, and weathering differences between damaged and undamaged buildings; attach supplier discontinued notices — see Roof Matching Documentation Guide.
• →Uniform appearance — photograph elevation comparisons showing visible mismatch when only damaged buildings are replaced; uniform appearance arguments apply across campus sightlines.
• →Functional damage — record creased tabs, broken seals, granule loss exposing mat, and bruising that affects water-shedding performance per building and elevation.
• →Repairability — perform and photograph repairability tests per building; document brittleness, seal failure, and collateral damage risk — see Roof Repairability Documentation Guide.
• →Manufacturer guidance — attach spec sheets showing patch limits exceeded on specific buildings; manufacturer requirements often drive full-slope replacement on multi-building campuses.

• →Separate building estimates — create distinct estimate sections or files per building when carrier templates allow; scope comparison tables must map every line to building IDs.
• →Combined estimates — when carriers require single-file submission, include building-indexed scope tables and photo cross-reference sheets so desk reviewers can navigate multi-structure scope.
• →Mobilization — log separate mobilization dates per building or phase when production is sequenced; photograph setup and teardown at each deployment.
• →Crane costs — document building height, setback constraints, and crane setup locations per structure when hoisting is required on multi-story buildings.
• →Safety equipment — record parapet heights, steep-slope conditions, warning-line requirements, and tie-off limitations that vary across buildings on the same campus.
• →Material staging — photograph staging areas, delivery paths, and storage constraints per building zone; narrow campuses and occupied properties require documented logistics.
• →Waste factors — document cut-up geometry, multi-level sections, and layer counts per building that affect waste calculations beyond single-structure averages.
• →Access costs — record gated entry, escort requirements, parking restrictions, and narrow driveways that support access and logistics line items.
• →Temporary protection — document emergency tarping, dry-in, and temporary repairs per building with date-stamped photos before permanent scope is negotiated.
• →Scheduling impacts — log phased production schedules, tenant coordination delays, and weather interruptions per building with contemporaneous date stamps.
