A planned roof replacement is a useful time to review existing skylights. If an older unit is likely to need work soon, deciding before the reroof can avoid reopening new roofing later. That does not mean every skylight must be replaced simply because the shingles are changing.
For your Santa Rosa project, ask for a condition-based recommendation. The skylight’s age, visible condition, leak history, and connection to the new roof all belong in the conversation.
Make reuse or replacement an explicit decision
Check whether the estimate assumes the existing skylight stays in place. If so, ask how its flashing and surrounding roofing will be handled. If replacement is proposed, ask why and which unit is included.
VELUX identifies reroofing as an opportunity to coordinate skylight replacement because work around a skylight affects the adjoining roof materials. Its guidance also describes the product-specific steps involved in replacement. VELUX skylight replacement guidance.
Treat that as a reason to plan the work together, not as proof that one brand or product is required for every house.
Identify the existing unit before ordering
If you have an old invoice, model information, or an interior-accessible label, share it. The size of the opening, mounting arrangement, and roof configuration all affect the options. Do not measure from the roof yourself.
Ask what needs to be confirmed on site and when the product must be selected to fit the roofing schedule. A replacement described only as “new skylight” leaves open questions about its operation, glazing, appearance, and compatibility.
Separate the roof work from the room below
A skylight project can involve more than the unit and flashing. Ask whether interior drywall, paint, trim, or other finish work is included. If another contractor is needed, identify when that work should happen.
If you are changing from a fixed to an opening unit, discuss any additional requirements before accepting the scope. The estimate should describe the product and work being supplied, not leave the homeowner to infer features from a photo.
Keep the documents together
Save the product information, installation record, and applicable warranty documents with the roof paperwork. Different components can have different terms. Ask about the written coverage that applies to the actual products and installation rather than assuming a general marketing statement covers the entire project.
