Question 1

Does a satellite dish mount on my Calgary roof cause leaks?

Accepted Answer

Satellite dish mounts are one of the more common hidden sources of roof leaks in Calgary, and the reason is straightforward: every bolt or lag screw driven through the shingles and decking creates a penetration that needs a proper seal to stay watertight.

Why Calgary's Climate Makes This Worse

A mount installed with no flashing or sealant is a problem anywhere, but Calgary's roughly 128 freeze-thaw cycles a year turn a small gap into a bigger one fast. Water seeps under the shingle around the

Question 2

What is kickout flashing and why does Calgary siding need it?

Accepted Answer

Kickout flashing is a small L-shaped or angled piece of metal installed where a sloped roof meets a vertical wall, specifically at the lower end of a step-flashing run where the roof edge terminates into siding. Its job is to redirect water that runs down the roof slope away from the wall and into the eavestrough, rather than letting it travel behind the siding. Without it, every rainstorm sends a sheet of water straight into the gap between the bottom course of step flashing and the siding, whe

Question 3

Does a bigger skylight need a City of Calgary permit?

Accepted Answer

Yes, a larger skylight requires both a development permit and a building permit from the City of Calgary. That applies whether you are going bigger or smaller; any size change triggers the dual-permit requirement. Replacing a skylight with one of the exact same size does not need a permit.

Why the Size Change Matters

A skylight opening is a structural modification. Cutting a bigger hole in the roof deck means altering the rafters or trusses around it, which is structural work. That takes the

Question 4

Should skylights be replaced when my Calgary roof is replaced?

Accepted Answer

Skylights don't have to be replaced at the same time as your roof, but it's often the smartest moment to do it, and the decision hinges on the skylight's age, condition and how it's flashed into the new roofing.

Should You Replace the Skylight Now?

A roofing crew will remove and reinstall the flashing around every skylight on the roof regardless. That labour is already priced into the job. If the skylight itself is more than 15 to 20 years old, the seals between the panes are likely failing o
