Professional Skylight Repair & Replacement You Can Trust
Skylights are the most failure-prone part of any Calgary roof. UV exposure destroys seals faster than anything else on the roof, freeze-thaw cycles crack flashings, and hail breaks or stresses glazing. The first sign of skylight failure is usually a water stain on the ceiling around the skylight or condensation between glazing panes — by then the seal has been failing for 6-24 months. We diagnose whether the leak is the skylight itself, the flashing kit around it, or a separate roof issue and provide a written scope for whichever repair or replacement is needed.
Common Causes in Calgary Homes
We see these patterns repeatedly across Calgary and area. Knowing the cause helps us respond faster and recommend the right solution.
Hail-Damaged Glazing
Large hail can crack tempered glass skylights and crater plastic dome skylights. We document and assess hail damage to all skylight components during the roof inspection.
Failed Flashing Kits
Skylight manufacturer flashing kits typically last 15-20 years before sealants fail. Often the actual leak source — the skylight itself is fine.
Failed Glazing Seals
Condensation between dual or triple glazing means the seal has failed. Older Velux units (pre-2005) commonly need re-glazing or full replacement.
Improper Original Installation
Skylights installed without proper flashing kits or counter-flashing fail within 5-10 years instead of 25-30. Replacement requires correcting the original install errors.

Skylight Repair FAQs
Common questions about skylight repair & replacement in Calgary, AB.
Should I repair or replace my old skylight?
Repair if the skylight is under 10 years old and the leak is at the flashing kit. Replace if the skylight is over 15-20 years old, has failed glazing seals, or has dome cracks from hail. Repair costs CA$300-CA$800; replacement runs CA$800-CA$2,500 depending on size and brand.
Was my skylight damaged in the same hail event as my roof?
Quite possibly. Large hail can crack tempered glass skylights and crater plastic dome skylights. We document skylight condition during the roof inspection and include it in the written damage report so you have a complete picture of everything affected.
What's the best brand for Calgary climate?
Velux is the gold standard — proper flashing kits, replaceable glazing, and 20+ year reliable performance in Calgary conditions. Sun-Tek and Solatube are also strong performers. Avoid cheap big-box dome skylights — they crack from UV within 8-12 years in Calgary's UV exposure.
