Retrofitting old skylights into new Velux skylights: Edmonton indoor pool project
Older skylights don’t always fail all at once. More often, they slowly become a problem—leaks, condensation, heat loss, and ongoing repairs that never quite solve the issue.
That was the case with this Edmonton home featuring an indoor pool and vaulted ceiling, where outdated skylights were no longer performing as they should.
At Weatherproof Roofing, we recently completed a full skylight retrofit that transformed the space—both structurally and visually.
The original problem: Large, aging skylights over an indoor pool
The home originally had:
7 large, older skylights
Installed years ago with dated materials and flashing
Located above an indoor pool, where heat, humidity, and condensation are constant challenges
A vaulted roof system that was not properly designed to manage moisture long-term
Over time, the homeowner experienced:
Condensation issues
Energy inefficiency
Increased risk of leaks
Concerns about long-term roof performance
This wasn’t a situation where patch repairs made sense. A proper solution required rethinking the entire skylight installation and roof system.
The solution: Skylight retrofit with 14 Velux skylights + hot roof conversion
Instead of pursuing skylight replacements one by one, we designed a full retrofit solution that addressed performance, durability, and comfort.
1. Replacing 7 old skylights with 14 new Velux skylight installations
Rather than reinstalling large, outdated skylight units, we:
Removed all 7 original skylights
Reconfigured the roof openings
Installed 14 properly sized Velux skylights
This approach delivered:
More even natural light distribution
Reduced condensation risk per unit
Better thermal performance
A cleaner, more modern appearance inside the space
The Velux skylight replacement was chosen for the brand’s:
High-performance glass
Energy efficiency
Engineered flashing systems
Proven reliability in Alberta’s climate
2. Rebuilding the vaulted roof as a hot roof system
Because this skylight assembly sits above an indoor pool, moisture control was critical.
We completely rebuilt the vaulted section of the roof into a hot roof system, which means:
Insulation is installed directly at the roof deck
No cold attic space where condensation can form
Improved air sealing
Better temperature control year-round
This is especially important in pool environments, where warm, humid air constantly rises toward the roof structure.
Why this approach matters (especially in Edmonton)
Indoor pools create one of the most demanding environments for a roof system:
High humidity
Constant temperature differences
Increased condensation risk
Freeze–thaw stress in winter
By combining:
Properly sized Velux skylights
Factory-designed flashing systems
A hot roof assembly
Professional installation and detailing
…the result is a roofing system built for long-term performance, not short-term fixes.
The result: A bright, comfortable, and leak-resistant space
After completion:
The homeowner now enjoys 14 evenly spaced Velux skylights
Natural light floods the pool area without harsh glare
Condensation issues are significantly reduced
The roof system is properly insulated and sealed
Peace of mind knowing the system is built correctly
Most importantly—the customer is extremely happy with both the performance and the finished look of the space.
Can old skylights be retrofitted instead of just replaced?
In many cases, yes—but it depends on:
Roof structure
Ceiling design
Moisture conditions
Long-term goals of the homeowner
This project is a great example of how retrofitting can be a better solution than simply swapping old skylights for new ones.
