- Skylight replacement
- Leaking skylight repair
- Skylight flashing replacement
- Flat-roof skylight replacement

New Skylight Installation
Installing a new skylight is an excellent way to introduce natural light into kitchens, bathrooms, hallways, stairwells, bedrooms and finished attic spaces. Before installation, our team evaluates the roof structure, roofing material, slope, drainage and intended skylight location.
Proper placement and installation are essential. The skylight must be securely mounted and carefully integrated with the roofing system to prevent water intrusion. Our installation process includes the required flashing, underlayment and waterproofing materials necessary to create a durable, weather-resistant seal.
We install skylights on:
- Asphalt shingle roofs
- Modified bitumen roofs
- Torch-down rubber roofs
- EPDM roofing systems
- TPO roofing systems
- Low-slope and flat roofs
- Porches, additions and garages
Skylight Replacement
Skylights do not last forever. As they age, seals can deteriorate, flashing can loosen and the skylight frame or glazing can become damaged. Replacing an aging skylight before it begins leaking can help prevent expensive roofing and interior repairs.
A new skylight may also provide better insulation, improved UV protection, reduced condensation and increased energy efficiency compared with an older model.
When replacing a skylight, Roof Works inspects the surrounding roofing material, roof deck, curb and flashing. If we find moisture damage or deteriorated wood, we explain the problem and provide clear repair options before completing the installation.
Signs Your Skylight Needs Replacement
Contact Roof Works if you notice:
- Water stains around the skylight
- Active dripping during rain
- Condensation between the glass panes
- Cracked, cloudy or discolored glass
- Damaged or corroded skylight flashing
- Peeling paint or bubbling drywall
- Drafts around the skylight
- Visible mold or moisture
- A damaged skylight frame
- Recurring leaks despite previous repairs
- A skylight that is more than 15–20 years old
A professional inspection can determine whether the leak is coming from the skylight, its flashing or another section of the roof.
Skylight Leak Detection and Repair
A leak near a skylight does not always mean the entire skylight must be replaced. Water can enter through damaged flashing, deteriorated roofing materials, failed sealants or improper drainage around the skylight.
Our team examines the complete area to identify the actual source of the leak. When a reliable repair is possible, we explain the available options. If the skylight or surrounding components have reached the end of their useful life, replacement may be the more dependable and economical solution.
Flat-Roof Skylights in Philadelphia
Many Philadelphia row homes, rear additions and commercial buildings have skylights installed on flat or low-slope roofs. These installations require special attention to curb height, flashing, membrane attachment and drainage.
Water can collect around an improperly installed skylight curb, increasing the risk of leaks and roof-deck deterioration. Roof Works installs and replaces flat-roof skylights using waterproofing methods designed for EPDM, TPO, modified bitumen and torch-down roofing systems.
Skylight Flashing Replacement
Flashing creates a waterproof transition between the skylight and surrounding roofing system. Damaged, loose or incorrectly installed flashing is one of the most common causes of skylight leaks.
Depending on the roof and skylight, flashing replacement may include:
- Removing deteriorated roofing materials
- Inspecting the roof deck and skylight curb
- Installing waterproof underlayment
- Replacing step flashing or membrane flashing
- Sealing the surrounding roofing system
- Testing and inspecting the completed work
Roofing cement or surface caulk alone is rarely a dependable long-term correction for failed skylight flashing.
Benefits of Installing a New Skylight
A professionally installed skylight can provide:
- More natural light
- Improved interior appearance
- Better ventilation
- Reduced daytime lighting use
- Increased energy efficiency
- Greater comfort
- Improved property value
- A cleaner, more modern appearance
The precise benefits depend on the skylight style, glazing, placement and room where it is installed.

Frequently Asked Questions
How much does skylight installation cost in Philadelphia?
The cost depends on the skylight type, size, roof material, roof accessibility and whether structural or interior finishing work is required. Roof Works provides a free inspection and detailed estimate based on the property and proposed installation.
Can a leaking skylight be repaired?
Some skylight leaks can be corrected by repairing the flashing or surrounding roofing material. If the skylight frame, glass, seals or curb are deteriorated, replacement may provide a more reliable long-term solution.
Should I replace my skylight when replacing my roof?
If the skylight is old or showing signs of deterioration, replacing it during a roof replacement is often practical. This allows the new skylight and flashing to be properly integrated with the new roofing system.
How long do skylights last?
Many skylights last approximately 15–25 years, depending on the product, installation quality, roof conditions and exposure to weather. Older skylights should be inspected when the surrounding roof is repaired or replaced.
Do you install skylights on Philadelphia flat roofs?
Yes. Roof Works installs and replaces skylights on modified bitumen, torch-down, EPDM, TPO and other flat-roof systems commonly found on Philadelphia row homes and commercial buildings.
Why is there condensation around my skylight?
Condensation may result from indoor humidity, insufficient ventilation, poor insulation or a failed insulated-glass seal. An inspection can help determine whether the issue involves the skylight or indoor moisture conditions.
