For building owners and property managers

Commercial Roofing Services in Vancouver, BC

Paragon Roofing BC provides commercial roof repairs, maintenance and installation planning for Vancouver buildings. Tell us the roof type, signs of damage and how the building is used. Discuss the appropriate assessment and a proposed scope, including access, drainage, phasing, exclusions and the next step.

A leak above a shop, an ageing warehouse roof and a planned office building replacement call for different decisions. Our own roofing crew carries out the roofing work, with owner involvement and oversight. We connect the roof findings to a detailed written proposal so you can understand the recommended work and plan around your building.

Roof surfaces, glazing and wall transitions need to be considered together when defining the work.

The right starting point

Choose the work your building needs

The condition of the existing roof, the areas below it and the purpose of the project determine the useful next step. Choose the service that fits your situation, or tell us what you have noticed if you are unsure.

An existing problem

Roof repair and maintenance

Describe active leaks, repeat staining, damaged roof areas or drainage concerns. An assessment can help separate a local defect from a wider condition issue and establish the limits of the proposed repair.

For a repair request or an ongoing maintenance discussion, visit commercial roof repair and maintenance.

A planned investment

Roof replacement planning

Repeated repairs, changes to the building or a planned capital project may justify reviewing renewal options. Compare the existing assembly, proposed removal, drainage and access before treating a new roof covering as the whole project.

Replacement planning should identify what will be renewed, what may remain and which hidden conditions could change the scope.

A defined construction project

Commercial roof installation

For new construction or an agreed replacement, coordinate the roof system with the drawings, deck, rooftop equipment and responsibilities of other trades. The installation scope should also explain weather protection and the sequence of work.

Continue to commercial roof installation in Vancouver for this part of the project.

Tell us about the property

Use the form below to share the Vancouver address, your role, the roof concern and any timing or access constraints. If you know the roof material, approximate age or repair history, include those details. Say whether the issue is active and which occupied areas are affected.

Define the problem

What a commercial roof assessment should establish

An interior leak location is a starting point for investigation. It does not, by itself, establish the roof entry point or the amount of work needed. Bring together the leak history, accessible roof conditions and relevant records before choosing a repair or replacement.

The assessment scope should explain which areas can be inspected, what evidence will be recorded and whether additional investigation is proposed. A visual visit cannot confirm every concealed layer or deck condition.

Information that helps define the scope

  • The existing roof: known material, age, previous repairs and any available drawings or warranty records.
  • The affected areas: where and when water appears, changes after previous work and the spaces or equipment below.
  • Visible roof details: seams, flashings, wall junctions, roof edges, drains and equipment penetrations where accessible.
  • The next decision: a defined repair, further investigation, maintenance priorities or a renewal proposal, with the limits of each recorded.

Compare the actual options

Repair, recover or replace?

The useful comparison is what each option addresses, what remains in place and what uncertainty remains. Roof age alone does not settle that decision.

A defined repair

A repair may be appropriate when the defect is identifiable and the surrounding roof can support the proposed work. Ask which area is included, how it connects with the existing material and what will remain outside the repair.

A local repair should not be described as renewing the whole roof or resolving unrelated sources of water.

A possible recover

Installing a new covering over an existing assembly is a proposal to evaluate, not an automatic shortcut. Existing layers, moisture, attachment, drainage and the requirements of the proposed system need to be reviewed.

The written scope should explain why retaining the existing assembly is appropriate and what investigation supports that recommendation.

A replacement

Replacement may become the stronger option when deterioration is widespread, repeated repairs leave unresolved concerns or the project requires renewal of more of the assembly.

Define removal, disposal, any retained components and how concealed damage will be documented and priced if it is found during the work.

Materials within a complete assembly

Roof systems for flat and sloping areas

A commercial property may have more than one roof type. The roof deck is the supporting surface beneath the roofing layers. Flashings are the details that keep water out at walls, edges and openings. Compare the proposed system with the actual slope, deck, drainage, rooftop use and transitions. A product name alone does not describe how the finished roof will be built.

SBS modified bitumen
SBS modified bitumen is an asphalt roofing membrane modified with a rubber polymer for flexibility. A specified system uses compatible layers, commonly a base sheet beneath a cap sheet. The proposal should identify those layers and how they are attached, along with the waterproofing details at drains, walls and roof openings. Include how the selected installation method will be managed around occupants and rooftop equipment.
EPDM and other membrane options
EPDM is a synthetic rubber roofing membrane. TPO and PVC are thermoplastic membranes, with seams commonly joined using heat. Confirm the existing covering before choosing a repair material. For a new system, identify the membrane, attachment, seam method, flashings and compatible accessories in the proposal. These materials are different systems, so a repair method or product suitable for one may not suit another.
Metal roofing
For a suitable roof area, review the selected panel system, slope requirements, seams, edges and penetrations. Ask how the design addresses transitions to other roof materials. A metal finish does not, on its own, establish suitability for every roof slope or assembly.
Asphalt shingles on suitable sloping areas
Shingles may be part of a building with sloped roof sections. The scope should include the supporting roof condition and details at walls, valleys, vents and adjoining roof areas, as applicable. Keep these areas distinct from the specification for a flat roof membrane.
Standing seam metal roof with intersecting slopes and valleys
Metal roof slopes and valleys illustrate why the panel layout and transitions belong in the scope.
Asphalt shingles beside a wall with exposed underlayment and a roof vent
Roofing at a wall and vent involves details beyond the field of shingles.

Vancouver building logistics

Plan the work around the occupied property

For a shop or office, identify customer entrances and sensitive working areas. At a warehouse or industrial property, account for loading activity, stored goods and equipment access. Where a building has several occupants, agree who will communicate the work plan and any changes.

Record delivery access, material storage, disposal arrangements and the location of lifting equipment before comparing schedules. A proposal based on unrestricted access may not suit a property with a narrow lane or a busy loading area.

Street access and work boundaries

If roofing access, lifting equipment or material handling would occupy a Vancouver sidewalk, lane or street space, confirm the applicable street use permissions before booking that setup. This is a separate planning question from the roof work itself.

Agree how entrances, ventilation equipment, rooftop services and occupied areas will be managed. Work hours, any service interruptions and weather related changes should be discussed for the actual project. Evening or weekend work should be confirmed before it becomes part of the plan.

Compare proposals with confidence

What belongs in the scope and budget

Our detailed written proposals explain the roofing system and the work behind the price. Roof area is only one input. Review the specified materials, preparation, installation details and site arrangements with us so you understand what is included, what is excluded and what depends on further investigation.

Roof area and assembly
Identify each roof section, the existing deck beneath the covering, removal or retained layers, and the specified new materials. Where included, describe insulation and its attachment, the waterproofing layers, flashing at walls and openings, and drainage details. Ask which existing components will remain and why.
Access and operations
Account for height, access restrictions, lifting, staging, disposal, permitted work hours and the agreed approach to protecting occupied areas.
Other trades and approvals
State responsibility for equipment disconnection or reconnection, related building work and any applicable permits or inspections. Make exclusions visible.
Concealed conditions
Explain allowances, the process for documenting additional work and who must approve a change before it proceeds. Distinguish an allowance from a fixed included amount.
Completion records
Identify the photographs, scope records, maintenance information and written warranty documents that will be supplied, along with any remaining exclusions or follow up items.

From first enquiry to a useful record

Prepare for the work and the roof that follows

Agree the details that matter before the start date, then retain a clear record of what was completed. The work sequence and documentation should fit the agreed scope.

  1. Share the building information

    Provide the address, roof concern, access contact, operating hours and available roof history. Identify active problems and any planned work by other trades.

  2. Review findings and a defined proposal

    We explain the recommended roof system in the context of the findings and your building. Review our written specifications, preparation, inclusions, allowances and exclusions. Clarify any further investigation and how concealed damage will be recorded and approved if it is exposed during removal.

  3. Confirm access, communication and changes

    Agree delivery arrangements, the site contact, occupant notices, weather planning and the process for approving additional work. Confirm responsibilities before making commitments to tenants or other contractors.

  4. Keep the completion and maintenance record

    Retain the final scope, relevant photographs and written warranty terms. Record later leaks, repairs and rooftop equipment work so that future inspections start with the roof history. Discuss an appropriate inspection and maintenance plan for the installed system and property conditions.

Before you arrange the project

Commercial roofing questions

Does every commercial roofing project need the same permits?

No blanket assumption should be made from the word roofing. Confirm the requirements for the actual scope, including related structural or equipment work where applicable. Street access permissions may also need separate attention. The proposal should state who will confirm and manage the approvals that apply.

Can the business stay open during the work?

Discuss this against the proposed method, access, affected areas and operating needs of the building. Identify any restrictions or interruptions before agreeing the schedule. Continued operation and work outside normal hours should be confirmed for the project, rather than assumed.

What if the roof already has a warranty?

Provide the written documents before agreeing repairs or alterations. Review the applicable terms, exclusions, reporting requirements and responsibility for the proposed work. Do not assume that a new repair preserves every part of an existing warranty or creates coverage for unrelated roof areas.

How should rooftop equipment be included?

Identify equipment near the work area and any planned servicing or replacement. Confirm responsibility for its protection, access and any disconnection or reconnection. Roofing and equipment work should have clear boundaries so that required coordination is included in the plan.
