The company works with general contractors from specification review through mobilization, installation, quality control, and warranty closeout. Systems commonly include TPO, EPDM, PVC, SBS modified bitumen, metal, and specialty assemblies. The service is designed to support schedule certainty, trade coordination, and manufacturer-compliant installation. - [Re-Roofing & Restoration](https://ravenroofing.com/services/reroofing) > Raven Roofing provides commercial reroofing and restoration when localized repairs are no longer enough to manage leaks, moisture, and lifecycle risk. The work starts with investigation and moisture assessment, then moves into system recommendation, phasing, execution, and warranty closeout. Projects are planned to keep buildings watertight and operational while replacement proceeds. Typical goals include improved waterproofing, upgraded insulation, and a fresh manufacturer-backed warranty package. - [Roof Inspections & Condition Reports](https://ravenroofing.com/services/inspections) > Raven Roofing performs commercial roof inspections that document membrane condition, flashings, penetrations, drainage, and interior moisture evidence. These inspections are used for due diligence, budgeting, insurance, warranty compliance, maintenance planning, and replacement timing. The process can include rooftop review, interior review, reporting, and advanced testing such as moisture scanning or thermal imaging where needed. The company recommends routine inspections at least twice per year, usually in spring and fall, plus after major weather events. - [Maintenance Programs](https://ravenroofing.com/services/maintenance-programs) > Raven Roofing offers preventive commercial roof maintenance programs built around scheduled inspections, drain clearing, debris removal, sealant review, minor repairs, and written reporting. Programs are designed to catch small defects before they become emergency leaks, saturated insulation, or major repair events. Service cadence is generally tied to seasonal conditions in Metro Vancouver, the Fraser Valley, and the Sea-to-Sky corridor. The maintenance program also supports manufacturer warranty records and long-term capital planning. - [Leak Investigation & Repair](https://ravenroofing.com/services/leak-repairs) > Raven Roofing investigates commercial roof leaks by tracing the real water entry point rather than only patching where water appears inside. The process combines interior mapping, rooftop inspection, flashing review, drainage assessment, documentation, and advanced detection methods when required. Emergency response focuses first on containing active water intrusion and protecting the building interior. Permanent repairs are then completed using methods compatible with the existing roof system. - [Targeted Repairs](https://ravenroofing.com/services/targeted-repairs) > Raven Roofing performs targeted repairs for localized failures such as membrane punctures, open seams, flashing defects, penetration leaks, and drainage problems. This service is intended for roofs where the broader assembly is still serviceable and full replacement is not yet justified. Repair methods are matched to the existing system, including heat-welded repairs on TPO and PVC, adhesive repairs on EPDM, and compatible SBS repair techniques. Properly selected targeted repairs can extend roof performance for years and delay larger capital replacement. - [Emergency 24/7 Service](https://ravenroofing.com/services/emergency-service) > Raven Roofing provides 24/7 emergency commercial roof service for active leaks, wind damage, punctures, blocked drainage, visible membrane failures, and snow- or storm-related risks. Emergency response begins with intake, dispatch, temporary stabilization, and documentation so interior damage can be limited as quickly as possible. The company serves Metro Vancouver, Fraser Valley, and Sea-to-Sky, subject to crew availability, weather, and safe travel conditions. Emergency work then transitions into targeted permanent repairs or broader restoration planning as required. - [Roof Alterations](https://ravenroofing.com/services/alterations) > Raven Roofing completes commercial roof alterations for new rooftop equipment, penetrations, drainage changes, tenant improvements, skylights, access details, and structural additions. Alteration work is technical because every new detail changes waterproofing continuity and often affects warranty conditions. The company coordinates directly with mechanical, electrical, plumbing, and general contracting teams so the roof is not left exposed while other trades complete their work. Proper alteration work preserves roof performance and, where possible, protects existing manufacturer requirements. ## Complete Service FAQs ### New Construction Commercial Roofing - What types of new commercial roofing projects does Raven Roofing handle? > Raven Roofing installs roof systems for multi-family, commercial, industrial, institutional, and light-industrial new builds. We work with TPO, EPDM, PVC, SBS modified bitumen, metal, and specialty assemblies specified for BC projects. - How does Raven Roofing work with general contractors on new builds? > We coordinate from pre-construction through closeout, aligning roof design, procurement, site logistics, daily communication, and warranty documentation with the GC's overall schedule so roofing work supports the broader construction sequence. - How do I send a tender or bid invitation to Raven Roofing? > Send tender packages and bid invitations to estimating@ravenroofing.com. You can also call 604-531-9619 to discuss project requirements, timelines, and any prequalification information needed for bidding. - What safety standards does Raven Roofing follow on construction sites? > Our crews follow site-specific safety plans and WorkSafeBC requirements on every project. We focus on fall protection, clean staging, documented coordination, and daily site practices that protect both our team and other trades. ### Re-Roofing & Restoration - How do I know if my commercial roof needs replacement instead of more repairs? > Replacement is more likely when leaks are recurring, moisture is widespread, insulation is saturated, or repair spending is approaching a meaningful share of replacement cost. A professional inspection with moisture testing confirms whether the roof still has serviceable life. - What is the RCABC RoofStar Guarantee? > The RCABC RoofStar Guarantee adds third-party quality assurance inspection during installation. It gives owners another level of oversight on workmanship and assembly compliance when the project is completed by an eligible RCABC contractor. - How long does a commercial reroofing project usually take? > Timelines depend on roof size, phasing, access, weather, and system type. Most projects are planned in stages so sections can be dried in, tenants can keep operating, and site logistics remain manageable throughout the replacement. - Can you reroof during BC's rainy season? > Yes, but weather planning is critical. Temporary waterproofing, phased tear-off, and strict end-of-day dry-in procedures help manage BC rain events so the building stays protected while replacement work proceeds. ### Roof Inspections & Condition Reports - What does a commercial roof inspection include in BC? > A commercial roof inspection typically includes membrane review, flashing and penetration checks, drainage assessment, photo documentation, and a written report with prioritized recommendations. Interior signs of moisture and warranty-related concerns are also reviewed when needed. - How often should a commercial roof be inspected? > NRCA guidance commonly points owners toward inspections at least twice per year, usually in spring and fall. Additional inspections are recommended after major storms, unusual rooftop traffic, or any event that may have damaged the membrane. - Who usually needs a commercial roof inspection? > Property managers, owners, strata councils, facility teams, consultants, and buyers all use roof inspections to understand condition, support budgets, evaluate leak complaints, and confirm whether maintenance or replacement planning is needed. - Do regular roof inspections help with warranty coverage? > Yes. Documented inspections and maintenance support warranty compliance because many manufacturers expect owners to address developing issues and keep records that show the roof was monitored and maintained properly. ### Maintenance Programs - What does a commercial roof maintenance program include? > Most programs include scheduled inspections, drain clearing, debris removal, sealant maintenance, minor repairs, and written reporting. The scope is adjusted to roof size, system type, access conditions, and how aggressively the owner wants to manage lifecycle risk. - Why are maintenance programs important for commercial buildings in BC? > BC roofs face long rain seasons, moisture exposure, and in some regions freeze-thaw cycling. Maintenance catches blocked drains, membrane damage, and failing sealants early so those issues do not grow into emergency leak events. - Do maintenance records help with manufacturer warranty coverage? > Yes. Many roof warranties depend on documented inspections and reasonable maintenance. A structured program creates records that help owners show the roof was monitored, serviced, and protected from preventable neglect. ### Leak Investigation & Repair - How do commercial roofers find the source of a roof leak? > Leak detection combines interior mapping, rooftop inspection, flashing review, drainage analysis, and sometimes moisture scanning or controlled testing. Water often travels laterally through the assembly, so the visible leak is not always the actual entry point. - Can a commercial roof leak be repaired without replacing the whole roof? > Often, yes. Failed flashings, punctures, open seams, and drainage issues can frequently be repaired locally if the surrounding roof system is still in serviceable condition. Inspection is what confirms whether repair is realistic. - How quickly can a commercial roof leak be repaired? > Emergency stabilization can usually be completed much faster than permanent repairs. The final repair schedule depends on weather, safety, material compatibility, and how much investigation is needed to confirm the actual leak source. ### Targeted Repairs - What is a targeted commercial roof repair? > A targeted repair fixes a localized roofing problem such as a failed flashing, puncture, seam opening, or drainage defect without replacing the entire roof. It works best when the overall membrane and insulation still have meaningful service life. - How do you know whether a roof needs targeted repair or full replacement? > The decision depends on how isolated the issue is, how much moisture is present, and how much service life remains in the broader assembly. Inspection determines whether local repairs are sound or whether failure is already widespread. - What types of commercial roof repairs does Raven Roofing perform? > We perform membrane patching, seam repairs, flashing replacement, drain and gutter work, penetration re-flashing, and other system-specific repairs on TPO, EPDM, PVC, SBS, metal, and related commercial roof assemblies. ### Emergency 24/7 Service - What should I do if my commercial roof is actively leaking? > Call 604-531-9619, move vulnerable contents away from the leak, collect active drips, and document the damage if safe to do so. Interior location details help the crew start the investigation faster once they arrive. - Why can the leak inside a building be far from the actual roof problem? > Low-slope roof assemblies let water travel laterally through insulation layers, deck flutes, and other components. That means the drip you see inside can be many feet away from the actual breach in the roof. - Does Raven Roofing charge extra for after-hours emergency service? > After-hours dispatch can involve emergency call-out rates. We discuss the situation and any applicable emergency pricing before a crew is sent so expectations are clear at the time of the call. - What areas does Raven Roofing cover for emergency roof service? > Emergency commercial roof service is available across Metro Vancouver, the Fraser Valley, and the Sea-to-Sky corridor, subject to crew availability, weather, and safe travel conditions at the time of dispatch. ### Roof Alterations - What is a commercial roof alteration? > A roof alteration is a planned modification to an existing roof system for new equipment, penetrations, drainage changes, skylights, access details, or tenant improvements. The work has to integrate with the current assembly without creating leak points. - Can roof alteration work affect an existing roof warranty? > Yes. Unapproved penetrations or detailing can jeopardize warranty coverage. Proper alteration work follows manufacturer requirements, uses compatible materials, and documents the modification so existing warranty obligations are not undermined. - How does Raven Roofing coordinate with other trades on roof alteration projects? > We coordinate directly with site leads, mechanical contractors, electricians, plumbers, and general contractors so roof work is sequenced with other trades instead of becoming a project bottleneck or creating exposed conditions on the roof. ## Roofing Systems Installed - TPO Single-Ply: /roof-systems/tpo > TPO is an energy-efficient thermoplastic membrane system with heat-welded seams, strong UV resistance, and reflective white surfaces that help reduce cooling loads. Raven Roofing has installed millions of square feet of TPO roofing across BC commercial buildings. The system performs well in coastal rain, interior temperature swings, and mountain UV exposure. It is commonly used on office, retail, industrial, and institutional low-slope roofs. - EPDM Rubber Roofing: /roof-systems/epdm > EPDM is a proven single-ply rubber membrane known for exceptional flexibility, weather resistance, and long-term durability. Raven Roofing uses EPDM where owners want predictable service life, strong cold-weather performance, and broad installation flexibility. The system is common on industrial, institutional, and multi-family properties across BC. EPDM can be fully adhered, mechanically attached, or ballasted depending on the building and performance target. - PVC Single-Ply: /roof-systems/pvc > PVC is a thermoplastic single-ply membrane selected for chemical resistance, fire performance, and welded seam strength. It is especially relevant for restaurants, food processing plants, healthcare buildings, laboratories, airports, and facilities with rooftop chemical or grease exposure. PVC also provides high reflectivity and strong durability in BC's wet climate. System design can be mechanically attached or fully adhered depending on wind and substrate conditions. - SBS Modified Bitumen (2-Ply): /roof-systems/sbs-modified-bitumen > SBS modified bitumen is a multi-ply roofing system that uses polymer-modified asphalt for flexibility and redundant waterproofing. It performs well in BC because it stays pliable in cold weather, handles complex detailing, and offers a backup waterproofing layer if the cap sheet is damaged. SBS is widely used on commercial and multi-family low-slope roofs with penetrations, drains, and regular maintenance traffic. Depending on the project, it can be installed using torch-applied, cold-applied, or self-adhered methods. - Metal Roofing & Cladding: /roof-systems/metal-roofing > Raven Roofing installs standing seam metal roofing, architectural panels, and metal cladding systems for sloped commercial applications across BC. Metal systems are valued for long service life, weather performance, non-combustibility, and snow-shedding capability. Raven's in-house metal shop fabricates flashings, copings, fascia, trims, and custom panel components for closer coordination between sheet metal and roofing work. These systems are common on industrial, institutional, hospitality, and architecturally driven commercial buildings. - Green Roof Systems: /roof-systems/green-roofs > Green roof systems use a waterproofing membrane topped with vegetation, drainage layers, growing medium, and related components. Raven Roofing installs both extensive and intensive assemblies for commercial and institutional projects where stormwater control, energy performance, visible amenity space, or sustainability targets are important. In Metro Vancouver, green roofs can help retain and delay a meaningful share of annual rainfall. System design depends on structural capacity, waterproofing selection, and long-term maintenance planning. ## Service Areas - Metro Vancouver: /service-areas/metro-vancouver > Raven Roofing serves Metro Vancouver from its Surrey headquarters, providing maintenance, repairs, inspections, reroofing, and emergency response across 21 municipalities. The region's main roofing pressures are prolonged rain, blocked drains, ponding risk, and moisture-driven deterioration of flashings and membranes.

Local presence supports faster response times and better scheduling than contractors treating Metro Vancouver as a secondary market. - Fraser Valley: /service-areas/fraser-valley > Raven Roofing serves Abbotsford, Chilliwack, Mission, Hope, Kent, Agassiz, and Harrison Hot Springs with full commercial roofing service. Compared with Metro Vancouver, Fraser Valley roofs face heavier freeze-thaw stress, more frequent snow load concerns, and a mix of industrial, agricultural, and commercial building types. Raven emphasizes seasonal maintenance, detailed condition assessment, and targeted repairs that hold up through winter cycling. The company treats the Fraser Valley as a core market rather than an outlying service call. - Sea-to-Sky Corridor: /service-areas/sea-to-sky > Raven Roofing serves the Sea-to-Sky corridor with local crews based in Squamish, covering North Vancouver, West Vancouver, Lions Bay, Squamish, Whistler, Pemberton, and Lillooet. Roofing work in this region is shaped by alpine UV, heavy snow, freeze-thaw cycles, wind-driven rain, and limited winter access windows. Raven's local presence supports same-day emergency response, pre-winter maintenance, post-melt inspections, and roofing specifications built for mountain conditions. The company positions itself as the only RCABC-certified roofing contractor with local crews in the corridor. ## Blog From the Rooftop — commercial roofing insights for BC property managers, building owners, and contractors: /blog - Commercial Roof Flashing Failures: Causes, Warning Signs, and Repair Solutions: /blog/commercial-roof-flashing-failures > This article explains why flashing failures are one of the leading causes of commercial roof leaks, especially in BC's wet climate.
