Three ways we help you see more
From listing-ready real estate content to inspections that catch what the ground can't, every flight is built around one goal: showing your property clearly.
Expert pilots. Exceptional results.
At Zwellow, we are more than just drone operators. We are experienced flight reviewers and certified aviation professionals. Our team brings together decades of combined flight experience, with over 10,000 hours of cumulative flight time.
As certified flight reviewers, we understand aviation safety, precision, and technical excellence at the highest level. This expertise translates into every flight we conduct.
We live and breathe drones. This is not just a job for us, it is a passion. We are based right here in Calgary and have worked projects all across Alberta.
What our drones catch that you can't see
Every roof tells a story from above. Here are real issues we've identified during our drone inspections across Calgary.
High Risk
Overhanging Vegetation
Tree limbs touching the roof create friction, scratching shingles and inviting moisture and pests.
Branches damage shingles, clog gutters, and can fall during Calgary's high winds. Annual inspection prevents costly emergency calls.
Urgent
Solar Panel Defect
Micro-cracks, delamination, and hot spots drastically reduce output and pose a fire hazard.
A single cracked cell can drop efficiency by 30%. Regular inspection catches issues before warranty expires.
Critical
Clogged & Detached Gutter
Gutters filled with debris or pulled away from fascia cause overflow and ice dams in winter.
Overflow rots fascia, erodes foundations, and lifts shingles. Pre-winter inspection saves thousands.
Moderate
Rusted & Loose Flashing
Corroded or lifted flashing around chimneys, vents, and roof valleys breaks the seal that keeps water out.
Flashing failure is one of the most common causes of hidden leaks. Catching it early avoids interior water damage.
High Risk
Missing or Damaged Shingles
Cracked, curling, or missing shingles expose the roof deck directly to Calgary's wind, hail, and snow.
Exposed decking lets water in fast. Spotting damaged shingles early is far cheaper than a full leak repair.
Urgent
Spalling, Cracking & Water Stains
Surface spalling, cracked masonry, and water staining are visible signs that moisture is already getting in.
Staining usually means the damage underneath is worse than what's visible. Worth a closer look before it spreads.
