Your skylight installation details
Your estimate sits within the typical range.
Skylights range from a cheap tube that lights a hallway to a powered opening skylight that ventilates a room. Proper flashing and waterproofing at the roof is essential, a leaking skylight is a common and avoidable problem.
💰 Ways to save
- A tube skylight is far cheaper if you just need daylight in a dark spot.
- Shorter, straighter shafts cost less, position matters.
- Use an installer who flashes and waterproofs properly, leaks are the main skylight complaint.
