The right starting point

Connect the roof plan to the room below.

Replacing an existing skylight and adding a new opening involve different work. Roof slope, framing, shaft depth and room layout affect the options. We consider how the skylight will look from inside as well as how it connects to the roof, so both sides of the project are included in the discussion.

Explore your skylight project

Skylight replacement

Review aging units, glazing and flashing to determine an appropriate replacement scope.

New skylight openings

Discuss location, framing, the interior light shaft and the roof work needed to introduce a new skylight.

Fixed & venting options

Compare daylight-only units with operable options, considering room use and accessibility.

Flashing & interior finishing

Coordinate roofing, flashing, drywall and trim around the opening for a complete installation.

Plan with confidence

Details to discuss before work begins

Locate the source of a leak

Water near a skylight can involve the unit, flashing or surrounding roof. Condensation is another issue to distinguish during review.

Think about comfort & control

Discuss glass, shading and operation based on how sunlight enters the room and how you plan to use the space.

Coordinate roof replacement

Review an existing skylight when the roof is being replaced so the connected work can be planned together.

What shapes the estimate?

The number and size of skylights, roof access, fixed or venting features, flashing, structural changes and interior shaft work shape the estimate. A new opening usually requires a different scope from a same-size replacement.

Start with your project address, photos, priorities and preferred timing. We review the proposed scope and selections with you before moving forward.

Skylights: helpful answers

Can a leaking skylight be repaired?

Sometimes the issue is a flashing or roof detail; other situations involve an aging or damaged unit. We review the source of the problem before recommending repair or replacement.

Can I add a skylight where there is no existing opening?

A new opening can be discussed after reviewing the roof structure and room below. Framing, utilities, the light shaft and applicable approvals affect the plan.

Will the interior need work?

A replacement may need limited interior finishing, while a new opening can require shaft construction, insulation, drywall and paint. The estimate should make that distinction clear.
