Skylight Repair and Replacement by Problem
Leaking skylight flashing
Broward's HVHZ code treats a skylight like any other roof penetration: it's flashed with curbs, collars or pitch pans under RAS 111 or the roof's product approval. The building code also sets the curb height. On roofs pitched under 45 degrees, a skylight sits at least 4 inches above the roof plane, though a house can skip the curb on a roof of 3:12 or steeper. Typical bills:
- Resealing: $75 to $250
- Flashing repair: $150 to $500
- Leak repair overall: $225 to $800
Flashing details for walls, pipes and valleys are on the roof flashing repair page.
Impact-rated replacement units
The HVHZ chapter of the code names skylights, along with walls, doors and glazing, among the parts of a house that must pass impact testing or be protected by a device that has. A replacement unit also needs its own Florida product approval or Miami-Dade NOA (roof replacement explains how to look one up). A swap costs $800 to $2,400 and takes 3 to 5 hours. Replacing only the glass ($150 to $600) or the dome ($350 to $900) is cheaper, but ask whether the new part keeps the unit's approval.
New skylight openings
Adding a skylight where none existed runs $1,600 to $4,200 and 1 to 3 days. The framing around the hole must carry its share of the roof's design loads, and in the HVHZ no penetration may sit in a roof valley. Fixed units resist leaks better than ones that open, according to HomeGuide.
Tubular skylights
A tubular skylight brings daylight down a reflective tube from a small roof dome. Installed, guides put it at $500 to $1,000, well under a full-size unit. The dome is still a hole in the roof, so it needs a flashing base that matches the roofing around it, and you should ask whether the dome carries an HVHZ approval like a full-size unit.
