Every roof tells a story from above. Here are real issues we've identified during our drone inspections across Calgary.
High Risk
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
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
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
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
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
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.
