WHERE THE FIRST THING WE BUILD IS TRUST
CPR Group Ltd repairs, replaces, and installs skylights across Calgary, fixing leaks, replacing failed units, and integrating new skylights into asphalt, metal, and flat roof assemblies. Leaks around skylights almost always come from the curb, flashing, or surrounding membrane, not the skylight unit itself.
Our HAAG Certified Inspectors trace the leak to its actual source before anyone touches the glass, so you're not paying for a replacement when a flashing repair would have solved it.
Since 2007, CPR Group Ltd has served Calgary and Southern Alberta with full-service roofing, property restoration, and exterior renovations.
We offer a comprehensive range of skylight services to meet the diverse needs of Calgary residents and businesses:
CPR Group diagnoses the leak source, curb flashing, step flashing, apron flashing, ice and water shield, or the skylight unit itself, then repairs the actual failure point. Most Calgary skylight leaks come from failed flashings or aged sealant, not the skylight unit.
When a skylight unit has cracked glass, seal failure, condensation between panes, or age-related deterioration, CPR Group replaces it with a new energy-efficient unit from Velux, Columbia, or another leading manufacturer, and re-integrates the flashing and surrounding roofing at the same time.
CPR Group installs new skylights on both residential homes and commercial buildings, handling the framing, curb construction, flashing details, and roof integration in one coordinated job. You get a single crew handling the full assembly, not a handoff between a carpenter and a roofer.
Our HAAG Certified Inspectors check skylight flashings, sealants, glazing, and curb condition, catching small failures before they cause interior water damage. Annual skylight inspections are inexpensive insurance for a high-failure-risk component.
CPR Group helps homeowners and designers pick the right skylight, fixed vs. venting, manual vs. motorized, low-profile vs. traditional curb-mount, based on the room, the roof slope, and Calgary's climate conditions.
Since 2007
CPR Group Ltd, Calgary's full-service roofing team since 2007, has installed and repaired skylights across the city on asphalt shingle roofs, standing seam metal, EPDM flat roofs, and SBS modified bitumen commercial assemblies. Skylights are a high-failure-risk component on any roof because they combine a penetration, a curb, multiple flashing types, and a product that expands and contracts differently from the surrounding roof.
CPR Group's HAAG Certified Inspectors understand how all of those elements interact in Calgary's temperature swings, and our crew details every flashing termination to the manufacturer's specification.
Every CPR Group skylight project is backed by $5 million in commercial general liability coverage through Federated Insurance, membership in the Alberta Allied Roofing Association (AARA) since 2021, active WCB-Alberta coverage since February 2013, and a BBB A+ accreditation held continuously since July 2015.
CPR Group serves Calgary, Airdrie, Okotoks, Chestermere, Strathmore, Red Deer, Lethbridge, Medicine Hat, Brooks, and High River.
Diagnosis
The metal flashing around the skylight curb is the single most common leak source. Over time, sealants dry out, fasteners lift, and corrosion opens small gaps where water tracks under the shingles. CPR Group rebuilds the flashing, not just the sealant.
Poor attic ventilation above the skylight causes ice to build up on the roof slope below. Water backs up under the shingles and drips through the curb flashing as if the skylight itself is leaking. The real fix is better ventilation and ice-and-water shield coverage.
In winter, warm interior air hits the cold underside of the skylight glazing and condenses. The water runs down the interior trim and looks exactly like a roof leak. CPR Group checks for this before recommending any repair, sometimes the solution is a bathroom fan, not a new skylight.
When a skylight unit is 15–25 years old, the seal between the glazing and the frame eventually fails, showing up as condensation between the panes or a white haze on the glass. At that point, unit replacement is the right call.

Properly installed modern skylights reduce daytime lighting loads and, when venting, can assist with passive cooling during summer months. Low-E glazed skylights also reduce solar heat gain compared with older single-pane units. CPR Group installs energy-efficient skylights from Velux, Columbia, and other leading manufacturers.
