Our Roof Skylight Repair Services

We address various roof skylight issues, focusing on functionality, durability, and energy efficiency. Our services ensure safe installation, effective leak repair, and timely replacement to protect your property from further damage.

Commercial buildings have unique skylight structures that demand specialized repair techniques. We inspect all components, including flashing, seals, and framing, to pinpoint leaks or structural weaknesses. Our repairs prevent water intrusion that could disrupt business operations or damage interior assets.



We use high-quality materials designed to withstand mechanical stress and environmental factors common in commercial settings. Our team ensures minimal disruption during service, allowing businesses to maintain normal activities while we work.

For residential properties, we prioritize the integration of skylight repairs with maintaining aesthetic appeal and home comfort. We identify issues like cracked glass, faulty seals, and insulation gaps that can increase energy costs.



Our approach includes sealing leaks and reinforcing skylight frames to prevent drafts or water damage. We also consider the roof’s overall condition to ensure the skylight remains a secure and functional feature in your home.

Leak Detection and Repair

Early detection of skylight leaks is crucial to avoid extensive water damage. We employ visual inspections and moisture detection tools to locate leaks accurately.



Once found, we repair or replace damaged flashing, seals, and surrounding roof materials. Our methods focus on restoring a watertight seal between the skylight and roof, protecting your structure from mold, rot, and insulation damage.

Skylight Replacement

When repair is insufficient, we offer skylight replacement using energy-efficient, durable models tailored to your roof type and design. Proper removal of the old unit prevents damage to the roof deck and framing.



Installation includes precise flashing and sealing to avoid future leaks or drafts. We ensure the new skylight improves natural lighting and thermal performance, contributing to lower energy bills and enhanced occupant comfort.

Specialized Roof Skylight Repairs

We focus on precise repairs that ensure the integrity and performance of skylights on both commercial and residential buildings. Each repair addresses specific issues critical to preventing leaks, storm damage, and structural concerns.

Flashing Repair Around Skylights

Flashing is vital in creating a watertight seal around skylights. Damaged or improperly installed flashing can lead to water intrusion, causing leaks and potential interior damage.



We inspect flashing thoroughly and replace or reseal it using durable materials designed for outdoor exposure. Our approach ensures the transition between roofing and skylight is secure, reducing the risk of future leaks.


Proper flashing repair also extends the life of the skylight installation and prevents costly repairs from water damage beneath the roof surface.

Storm Damage Restoration

Storms can cause cracks, broken glass, or damaged seals on skylights, compromising energy efficiency and safety. Our restoration services focus on prompt assessment and repair to minimize further exposure.



We handle glass replacement, frame repairs, and resealing to restore skylights to their original condition. We prioritize quick service to protect both commercial roofs and residential properties from ongoing weather damage.


Our team works with insurance companies when applicable to assist with claims and ensure proper documentation of all repairs.

Roof Structural Repair

Skylight issues sometimes stem from underlying roof structure problems. We evaluate the roof framing and decking to identify areas weakened by water, rot, or physical impact.



When structural repairs are needed, we reinforce or replace damaged components to support skylight stability and prevent sagging or collapse. This is especially important in commercial buildings with heavier roof loads.


Addressing the roof structure protects the skylight and enhances overall roof durability, ensuring both meet safety standards and perform well over time.

Roof Skylight Repair FAQs

  • How much does skylight repair cost in Mission Viejo?

    Skylight repairs typically range from $275-$750, depending on the issue complexity and skylight type. Simple resealing or flashing repairs start around $275-$350. Replacing damaged glass or acrylic panes costs $350-$525, while fixing operational mechanisms on VELUX or Fakro venting skylights runs $400-$650. Full curb rebuilding with new flashing kits costs $550-$750. Commercial skylight repairs for larger units or architectural glass systems start at $650.

  • What are the most common skylight leak problems?

    The most common issues include deteriorated flashing where the skylight meets the roof, failed sealant around glass perimeters, cracked glass or acrylic panels, and worn gaskets between frame components. We frequently encounter improper initial installation where step flashing wasn't properly integrated with roofing materials. In fixed-dome acrylic units from manufacturers like Wasco or CrystaLite, hairline cracks often develop from thermal expansion. Tubular skylights like Solatube and ODL Tubular frequently leak at the roof flange connection, while operable units typically develop problems with weatherstripping or perimeter sealants.

  • Can a leaking skylight be repaired or does it need replacement?

    Most leaking skylights can be repaired rather than replaced. Issues with flashing, sealants, gaskets, and operational mechanisms typically respond well to professional repair. When double-pane glass units develop condensation between panes or when frames have structural deterioration, replacement becomes necessary. For skylights over 15 years old with multiple leak points, replacement with modern units from VELUX or Fakro is often more cost-effective long-term. We provide honest assessments based on skylight condition—sometimes a $350 repair adds 7-10 years of service life, making repair the smarter investment.

  • How long does professional skylight repair take?

    Most residential skylight repairs take 2-4 hours to complete. Simple resealing services or flashing repairs typically require 2 hours, while operational mechanism repairs or glass replacement may take 3-4 hours. Complex repairs involving curb rebuilding or extensive flashing integration with surrounding roofing materials may require 4-6 hours. We complete most residential repairs in a single day, working efficiently to minimize disruption. Commercial projects involving multiple skylights may require scheduling over 1-2 days, depending on accessibility and scope.

  • What causes skylights to leak during rainstorms?

    Leaks during rainstorms typically stem from deteriorated flashing, cracked sealants, or improper integration between the skylight and roofing materials. Mission Viejo's occasional heavy downpours test skylights with wind-driven rain that pushes water under flashing or through microscopic cracks in caulking. Thermal expansion from our intense sun causes gradual separation between components, creating entry points for water. Improperly sloped curbs that don't shed water quickly enough allow pooling that eventually finds weak points.
