What does this skylights and roof glazing rough-in checklist cover?

13 items across 5 sections, covering fall protection at openings, units on site, curb and opening, flashing and membrane tie-in, and more. Each item spells out what the person walking the job is actually looking for, not just a box to tick.

Who should run this inspection?

The skylight installer setting curbs and frames with the roofing foreman, or the GC's superintendent walking each opening before the roof closes over the tie-in.

When in the schedule should this walk happen?

As curbs and frames are set on the framed openings and the flashing is woven into the roof, before the membrane or shingles cover the transition and before the unit is glazed.

Why do these items ask for a photo?

9 of the 13 items call for photo evidence, 12 photos in all. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.

What most often fails a skylights and roof glazing rough-in inspection?

Curb set low so the membrane base flashing turns up short of the height the manufacturer calls for, and standing water finds the top of the flashing in the first hard rain. Flashing lapped against the drainage instead of shingle-fashion with the water, so the upslope side counts on sealant alone and leaks once the sealant ages. Curb set out of square or racked to the deck, so the unit will not seat evenly and the perimeter gasket is pinched on one side and open on the other.

Can I use this checklist in RTI?

Work is commonly verified against the applicable building code, NRCA roofing guidance, manufacturer's published instructions. Confirm the edition your authority having jurisdiction has adopted.

The checklist

Every item, and the photo evidence it needs

The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.

Fall protection at openings

Openings guarded or covered before anyone walks the curbs
Every skylight opening in the roof area has the guardrail, secured cover or screen the site's fall protection plan calls for; if one is open, stop and report it to the super.
Fall protection plan and cover markings checked for this roof
Site fall protection plan reviewed with the super for this roof area; covers fastened against displacement, marked as covers and rated for the load the plan states.
No photo

Units on site

Frame and unit labels match the approved submittal
Manufacturer's label or carton on each frame and unit read for model, size and glazing type and compared with the approved submittal and the opening's schedule mark.
Units stored crated, secured and away from roof edges
Crated units stored as the carton marks direct (flat or on edge), covered, tied down against wind and kept clear of roof edges and open curbs.

Curb and opening

Curb square, level and to the required height
Curb built plumb and square to the opening, top level, upstand at or above the height the manufacturer and roof assembly call for so base flashing turns up full.
Opening framed and blocked to carry the unit
Header and trimmers sized for the opening, curb fastened to solid framing not just decking, no soft spots under the anchor line.
Curb outside size measured against the unit's frame
Curb outside dimensions taped at both directions and compared with the range the manufacturer lists for this unit, so the frame seats without forcing or open gaps.

Flashing and membrane tie-in

Flashing lapped shingle-fashion and tied to the roof
Base, step and counterflashing woven with the drainage so upslope water sheds over each lap, membrane turned up the curb and terminated, no reliance on sealant as the primary seal.
Upslope diverter or cricket where the run demands it
On wide curbs or low slope, a cricket or diverter behind the unit splitting water around the curb instead of ponding against the upslope flashing.
No photo
Curb and flashing details for each unit type on hand
Manufacturer's curb and flashing drawing and the current roofing details at the roof for each unit type, with the curb height and counterflashing lap they call for noted before flashing starts.
No photo
Counterflashing parts match the manufacturer's detail
Counterflashing or kit parts on site checked by label against the manufacturer's detail for this unit and roof covering, no field-bent substitutes the roofing details do not show.

Concealment signoff

Tie-in photographed before the roof covers it
Each opening's flashing and membrane termination documented open, curb height and laps visible, before shingles or cover board close the transition for good.
Skylight schedule checked off opening by opening
Every opening on the skylight schedule found on the roof with its mark, curb built and flashed; missing, moved or extra openings reported to the super.
No photo

What usually sends this back

The failures are almost always the evidence, not the work

Curb set low so the membrane base flashing turns up short of the height the manufacturer calls for, and standing water finds the top of the flashing in the first hard rain.
Flashing lapped against the drainage instead of shingle-fashion with the water, so the upslope side counts on sealant alone and leaks once the sealant ages.
Curb set out of square or racked to the deck, so the unit will not seat evenly and the perimeter gasket is pinched on one side and open on the other.
