SKYLIGHT LEAK Repair
Is Your Skylight Leaking?
Every skylight leak traces back to the same three failure points: the sealant, the flashing, and the curb tie-in. Ignore any of them long enough and the membrane around the skylight goes with it.
At Videl Roofing, we diagnose the actual failure point and rebuild your skylight's seal, flashing, and membrane in a single trip.

SKYLIGHT Installation
New Skylight Installed in Under 48 Hours
Our skylight installation services never disrupt your day-to-day operations.
Cut and frame the opening
We measure from inside the building, mark the cut on the deck, and frame the curb to manufacturer spec. If the work runs past one day, the opening is properly sealed to prevent leaks.
Install the curb and tie into the membrane
The curb is fastened to the deck and integrated with the surrounding flat roof system. Flashing is installed in continuous plies, fully tied into the existing membrane.
Set the skylight and seal the perimeter
Finally, the skylight is set onto the curb, fastened, and sealed with high-grade sealant rated for Ontario freeze-thaw. We pressure-test the seal before leaving the site.
What Daylight Does for a Commercial Property
Skylights are one of the few upgrades that improve how a commercial building looks, feels, and operates all at once. Tenants notice the daylight. Owners notice the lighting bills. Buyers notice it on the walkthrough.
A new skylight runs $800 to $2,500 installed, and repairs on an existing unit run $200 to $700. Every job is quoted as a fixed price after a free roof assessment.

How much does it cost to install a skylight on a flat roof?
New skylight installation runs $800 to $2,500 per unit, depending on size, glazing type, and how much curb and flashing work the existing roof needs. Repairs on an existing skylight run $200 to $700. Every job is quoted as a fixed price after a free on-site assessment.
What are the best skylights for flat roofs?
Curb-mounted dome and pyramid skylights are the standard for flat commercial and industrial roofs. They sit above the membrane plane, shed water naturally, and integrate cleanly with BUR, modified bitumen, EPDM, and TPO systems. Flat glass units are also an option when the architectural look matters.
Can you put a skylight in an existing commercial roof?
Yes. Most of the skylight installations Videl does are retrofits on existing flat roofs, not new construction. The work is done from the roof down, with minimal disruption inside the building and no need to open the interior ceiling in most cases.
Do you need a permit to install a skylight on a commercial flat roof?
Yes. In Ontario, skylight installation on commercial and industrial buildings almost always requires a building permit because the work involves cutting and framing the roof assembly. The residential exemption that allows skylight installation without a permit only applies to small houses, not commercial properties. Videl handles permit coordination and works to local code on every install.
Will adding a skylight affect my roof warranty?
A skylight installed correctly by a qualified commercial roofer will not void your membrane warranty, as long as the membrane tie-in is done with compatible materials and follows the manufacturer's spec. Videl installs to manufacturer standards and documents the work for warranty purposes.
