A commercial skylight project should be planned as part of the roof assembly, not as a separate product purchase. For a Southfield, MI facility, the useful questions are whether the proposed location works with the roof and structure, how the curb or opening will be detailed, how the roofing membrane will transition at the skylight, and whether the selected glazing and installation approach fit the building.
Core Values Construction confirms Skylight Install and Replacement within its commercial service scope. Facility managers can call (517) 260-3957 to discuss the roof, the existing opening if one is present, and the conditions that should be evaluated before installation or replacement.
Start With Roof and Location Suitability
Not every roof area is equally suitable for a skylight. Drainage, roof slope, structural framing, existing rooftop equipment, access paths, roof traffic, and the layout of the occupied space below can all affect the location. A planned opening should be evaluated with the roof and building design before a unit is ordered.
If the project is part of a larger roof or building project, Core Values Construction’s new construction roofing guidance for Southfield provides useful context for coordinating roof openings, penetrations, insulation, and other trades early.
Set Daylighting Goals Before Selecting Size and Placement
Skylight size and placement affect how daylight reaches the occupied space, but there is no universal size that works for every building. Interior ceiling height, room layout, orientation, glazing characteristics, nearby obstructions, and the intended use of the space can all influence the result.
A skylight may reduce electric-lighting use during some operating periods, but energy savings should not be assumed from the skylight alone. Lighting controls, glazing, HVAC loads, building use, and usable daylight all affect the outcome. If daylight performance is a major goal, ask how it will be evaluated before final selection.
Inspect the Existing Curb During Replacement
When an existing skylight is being replaced, the condition of the curb, surrounding roof materials, flashing, and nearby deck should be checked before the new unit is installed. A damaged or unsuitable curb can change the replacement scope, but not every existing curb automatically needs to be rebuilt.
The contractor should explain whether the curb can remain, whether repairs are needed, and whether the new skylight fits the existing opening. If dimensions or details change, the proposal should identify any framing, curb, flashing, or roofing work required to accommodate the new unit.
Coordinate the Skylight With the Roofing Membrane
The transition between a skylight curb and the roof is a critical waterproofing detail. The correct approach depends on the roofing system, curb design, flashing requirements, attachment method, and manufacturer or project specifications. Sealant alone should not be treated as a substitute for a complete roof-to-curb detail.
For membrane roofing, coordinate skylight work with the roofing contractor rather than treating the opening as an isolated trade. Core Values Construction’s EPDM roof installation page for Southfield provides related context for planning membrane details and attachment requirements.
Confirm Glazing and Code Requirements for the Project
Commercial skylight projects may be affected by energy, structural, safety, glazing, curb, and opening requirements. The exact requirements depend on the building, jurisdiction, project type, and code in effect, so a generic glazing package should not be assumed to satisfy every Southfield project.
Ask who is responsible for confirming applicable requirements and whether design or engineering input is needed. Glazing can affect heat transfer, solar gain, visible light, condensation risk, and comfort, so the specification should reflect the project conditions.
Use an Inspection to Define Existing Conditions
If the skylight is being added to an existing roof, or an older unit is being replaced, an inspection can help document the surrounding membrane, curb, flashing, drainage, and visible roof condition before work begins. That can separate skylight work from broader roof problems that should be addressed at the same time.
Core Values Construction’s commercial roof inspection page for Southfield provides related context for documenting roof conditions before the skylight scope is finalized.
Plan Installation Around the Occupied Building
Installation can affect both the roof and the interior area below it. The contractor should explain how the work area will be protected, how the opening will be managed during construction, how interior dust or debris will be controlled, and what happens if weather interrupts the planned sequence.
Ask which parts of the work are included in the skylight scope and which belong to other trades. Electrical work, interior finishes, structural modifications, roof repairs, access equipment, or ceiling work may need separate coordination depending on the building and project.

Frequently Asked Questions
How do I know whether a commercial roof can accept a new skylight?
The proposed location should be evaluated for roof layout, drainage, framing, rooftop equipment, access, and the conditions below the opening. Structural questions may require input from the appropriate design professional.
Does an old skylight curb always need to be replaced?
No. The curb should be inspected for condition, dimensions, attachment, and compatibility with the replacement unit before the scope is set.
What causes leaks around commercial skylights?
Leaks can involve the unit, curb, flashing, membrane transition, sealant, drainage, or nearby roof damage. The source should be identified before deciding what needs repair or replacement.
Will a commercial skylight reduce energy costs?
It may reduce electric-lighting use during some periods, but total energy impact depends on glazing, daylight controls, HVAC loads, building use, orientation, and other conditions.
