Skylight Spec & Curb-Mount Estimator

Curb-mounts are essential for flat or low-slope roofs (under 3:12 pitch) to ensure proper water shedding and flashing integration. Trying to use a deck-mount skylight on a low-slope roof is a major code violation and a guaranteed callback for leaks at the sill.

Don't just quote the roof work. If the home has an attic, you must frame a 'light tunnel' and finish it with drywall, tape, and paint. This interior labor often costs 2–3x more than the roof-side install. If you aren't line-iteming this burden, your skylight profit will vanish before the paint is dry.
