Skylight Replacement and Cost

"Should I replace the skylight when replacing my roof?"

In Edmonton, skylights have a similar lifespan as your roof, 20 some years. It often makes sense to replace your skylight along with the roof replacement due to the following reasons:

  • Roofers need to remove the existing skylight (the lid) when replacing your roof. This step ensures that the new waterproofing underlayment and metal flashings are tied in around the skylight and not resulting in a roof leak.
  • Aged skylights are fragile, and the skylight glass may crack or even break. Sometimes it is not possible to remove the old skylight without damaging them.

If your skylight is less than 15 years, then it is possible just to work around the skylight and not touching them at all. 

If your skylight is about 20 years old, then the best solution is to replace it at the same time as your roof. At Safe Roofing, our qualified installers will guarantee that your skylights are installed professionally and 100% watertight.

The cost of a custom-made, curb-mounted skylight can be expensive. With a roof replacement, you should budge extra money as follows: 

Curb preparation and flashing work is C$500. (discounted price) New skylight plus installation costs around C$1,000 to C$2,000 depending on the skylight profile and size. 

Deck-mounted skylight such as Velux is a bit cheaper. They are a low-profile skylight with flat glass and a set of measurements. Flashing kit, skylight plus installation costs around C$1,000 to $2,000.
