START WITH THE DECISION

What do you need to understand?

Aerial photographs can help you review visible roof areas and plan closer checks. The useful output is a record tied to your property and your question.

01

A roof you cannot see clearly

Steep slopes, upper roofs and complex layouts can make a view from the ground incomplete. Aerial images may help identify areas that need attention.

02

A property record

Organized roof photographs can support a maintenance discussion, a property transaction or a council review. Tell us who will use the record.

03

A specific concern

Share the location of a leak, visible damage or a change after a storm. The inspection may need interior access or closer checks alongside aerial images.

Aerial imaging can reduce the need for some roof access. It does not remove every site hazard or establish the condition of concealed materials.

TELL US ABOUT THE PROPERTY

Plan the right inspection.

Include the address, building type, number of buildings and the issue you want assessed. Let us know about an active leak, a report deadline or an existing roof quotation.

MATCH THE METHOD TO THE QUESTION

What images show and what needs closer inspection.

Image quality, viewing angle, obstructions and site conditions affect what can be assessed. A clear report distinguishes observations from items that remain unconfirmed.

On a small screen, scroll the table sideways to read every column.

Question What aerial images may show What may need another method
Roof covering Visible missing, displaced or damaged pieces and the overall roof layout. Small defects, concealed layers and details obscured by shadows or vegetation.
Roof openings and junctions The visible arrangement around skylights, chimneys, vents and walls. Hidden flashing laps, seal adhesion and connections beneath the covering.
Deck condition Exposed areas, where the deck is already visible during work. The condition beneath an intact covering, often requiring access from below or an agreed opening.
Attic moisture and ventilation Exterior outlets and visible roof features. Interior moisture evidence, insulation, air leakage and the complete ventilation path.
Leak investigation Visible areas that merit a closer check. Confirmation of the entry point and water path through the assembly.
Thermal patterns Surface temperature differences when suitable equipment and conditions are used. Interpretation and appropriate checks to establish the cause of a pattern.

Discuss how any follow up inspection will be arranged and priced. A photograph of a roof opening does not show every connection beneath it.

AERIAL ROOF VIEWS

See how the roof fits together.

Overhead and angled views show roof planes, openings and nearby structures. They provide context for deciding where a closer inspection may be useful.

THERMAL ROOF IMAGING

Temperature patterns need interpretation.

A thermal image shows surface temperature differences. It does not directly show water inside a roof.

Patterns may help identify areas for investigation, but sunlight, materials, reflections, viewing distance and weather can affect the image. A hot or cold patch alone does not establish a defect or a leak path.

If a thermal survey is proposed, confirm the roof assembly, the question being investigated, the equipment and method, and how findings will be checked. Wet insulation surveys on suitable insulated membrane roofs have specific inspection conditions. One timing rule does not fit every roof or every thermal task.

Ask whether thermal imaging and interpretation are included in the quotation. Ordinary aerial photographs and thermal analysis are different deliverables.

BEFORE A FLIGHT

The property and airspace shape the plan.

The site review should consider nearby people, neighbouring property, trees, wires, access, weather and the intended flight area. A roof being visible from the air does not establish that a flight can proceed.

Confirm the operator and permissions

Transport Canada requirements depend on the aircraft and the operation. Ask which pilot certificate, aircraft registration, safety requirements and airspace permission apply to the proposed flight. Controlled airspace operations can require permission from air traffic control.

Allow for changing conditions

The pilot must assess the site and operate within the aircraft and flight limits. Wind, rain, visibility or other conditions may require a different appointment or inspection method.

Discuss property access, occupant notices and the areas to be photographed before the visit. The scope should address neighbouring property and privacy as well as the roof itself.

Confirm site feasibility before relying on a particular inspection date or promising aerial coverage to an insurer, buyer or strata council.

COMPARE THE QUOTATION

What affects the inspection cost?

The quotation should match the property, the inspection question and the files or report you need. A flight alone and an interpreted condition report are different scopes.

On a small screen, scroll the table sideways to read every column.

Factor Why it matters Information to provide
Building count and roof area More roof areas can require more planning, capture and review. Address, number of buildings and available roof plans.
Roof layout and surroundings Height, shape, trees, wires and nearby activity affect access and image coverage. Known access restrictions and photographs taken safely from the ground.
Visual or thermal work Thermal work requires a suitable method, equipment and interpretation. The leak, moisture or heat loss question you want investigated.
Deliverables A photo set, annotated findings and a written report involve different work. Who will read the results and the required file or report format.
Site and flight requirements Airspace review, permissions and coordination can affect planning. Property contacts, occupancy details and any site rules.
Further investigation Closer inspection or other testing may be needed to resolve a finding. Whether interior access or follow up work should be included.

Request written inclusions, exclusions, timing and any additional charges before booking. If another visit becomes necessary, agree on that work before it proceeds.

A USEFUL RECORD

Agree on what you will receive.

A useful record connects images to the roof areas they show. It should explain what was observed, what could not be assessed and which items need further investigation.

Ask for the capture date, roof area references and a clear distinction between a visible condition and an interpretation. Keep the original files and report with your maintenance records.

  • Which buildings and roof areas are included.
  • Whether the deliverable includes photographs, video, annotations or a written report.
  • Any thermal analysis and its limitations.
  • Areas obscured, inaccessible or outside the agreed scope.
  • Recommended closer checks and the reasons for them.
  • The delivery format, recipients and agreed timing.

CLOSER ROOF DETAILS

Follow the image with the right checks.

Wall junctions and exposed decking show why different views answer different questions. Photographs record visible conditions; they do not establish how concealed layers are performing.

HOMES, STRATA AND COMMERCIAL PROPERTY

Use the record for the decision ahead.

Homeowners and buyers

Bring earlier repair records and explain your concerns. An aerial photo set can support a roof discussion, but it does not establish remaining life, a guarantee or the condition of hidden materials. For a property sale, discuss the required scope for pre listing roof documentation.

Insurance and commercial records

Ask the intended recipient what documentation they require. Photographs can record visible conditions, but they do not determine insurance coverage or guarantee acceptance of a claim. For storm concerns, see roof damage after heavy rain and wind and hail roof damage.

For concealed roof layers and junctions, read about underlayment and flashing scope or skylight inspection and repair questions.

COMMON QUESTIONS

Before booking an aerial inspection.

What is a drone roof inspection and why use one?

It uses aerial images to review visible roof areas. It can help with a property record or a specific roof concern, subject to the site, flight conditions and agreed scope.

Is a drone inspection a substitute for a physical roof walk?

It can answer some visual questions, but concealed layers, seal adhesion and interior conditions may need other checks. The inspection scope should explain the limits and any closer assessment required.

How much does a drone inspection cost in BC?

The price depends on the property, site requirements, imaging method and deliverables. Request a written quotation that distinguishes the flight, interpretation, report and any follow up work.

What does thermal drone imaging actually show?

It shows surface temperature patterns. These may guide further investigation, but they do not by themselves prove trapped moisture, a leak source or insulation failure. Suitable conditions and interpretation matter.

Are drones legal for commercial roof inspection in BC?

Drone inspection is subject to the rules for the aircraft and operation. Confirm the applicable pilot qualification, registration, aircraft requirements and airspace permissions with the operator before the flight.

Can I use my own drone footage for an insurance claim?

Ask your insurer or adjuster which records they require. Existing footage may be useful, but it does not guarantee acceptance or establish the cause or extent of damage. Keep the original files and capture information.

Can drone inspections work in BC weather?

Suitability depends on conditions at the site and the limits of the aircraft and operation. The pilot may need to postpone the flight or recommend another inspection method.

Do you use drone imaging for strata roof assessments?

Discuss aerial imaging as part of the assessment scope for your strata property. Identify the buildings, access contacts and intended report recipient so the proposed coverage and deliverables are clear.

How long does a drone inspection take?

Time varies with the property, conditions and agreed work. Ask for separate expectations for the site visit, image review and report delivery. Further investigation can affect the schedule.

Can I see drone images of my roof before the inspection report?

Agree on file access and delivery timing when booking. The quotation should state whether images, video and annotations are included and when each item will be available.
