Flat Roofing for Skylight Installation and Repair

Commercial buildings with flat roofing systems present unique opportunities and challenges when it comes to skylight installation and repair. These installations require specialized knowledge of membrane compatibility, proper drainage, and weatherproofing techniques that differ significantly from traditional sloped roof applications. Understanding these complexities is crucial for achieving long-lasting, leak-free results that protect your investment.


Skylights transform commercial spaces by introducing abundant natural light, reducing energy costs, and creating more inviting work environments. However, flat roofing for skylight installation and repair demands expertise in multiple roofing systems including TPO, EPDM, and modified bitumen membranes. 


Professional installation involves careful consideration of load-bearing requirements, proper curb mounting, and drainage management around skylight perimeters. Chicago's harsh weather conditions, including heavy snow loads and temperature fluctuations, make expert installation even more critical for preventing ice dams, condensation issues, and premature failure.


Repair services address common problems such as seal deterioration, cracked glazing, and flashing failures that can lead to costly interior damage. Regular maintenance and prompt repairs extend skylight lifespan while maintaining energy efficiency and structural performance.

Frequently Asked Questions

  • How much does skylight installation cost on a flat roof in Chicago?

    Commercial flat roof skylight installation in Chicago typically ranges from $1,500 to $4,500 per skylight, depending on size, type, and complexity. Standard 2x4 foot skylights average $2,000-$3,000 installed, while larger custom units or those requiring structural modifications can exceed $5,000. Factors affecting cost include roofing material compatibility, flashing requirements, and Chicago's specific building codes.


  • Can you install skylights on TPO/EPDM/modified bitumen flat roofing?

    Yes, skylights can be professionally installed on all major flat roofing systems including TPO, EPDM, and modified bitumen. Each material requires specific flashing techniques and compatible sealants to ensure watertight installation. TPO systems use heat-welded flashing, EPDM requires specialized adhesives and tape systems, while modified bitumen installations involve torch-applied or cold-process flashing materials that bond directly to the membrane.

  • What's the best type of skylight for commercial flat roofs?

    Curb-mounted skylights are typically best for commercial flat roofs because they elevate the skylight above the roof surface, reducing leak potential and allowing proper drainage. Double-dome polycarbonate skylights offer excellent durability and impact resistance for Chicago weather conditions. For high-performance applications, consider insulated glass skylights with low-E coatings and structural glazing systems that provide superior energy efficiency and longevity.

  • Do I need permits for flat roof skylight installation in Chicago?

    Yes, Chicago requires building permits for skylight installations on commercial buildings. You'll need to submit plans showing structural calculations, energy compliance, and waterproofing details to the Chicago Department of Buildings. The permit process typically takes 2-4 weeks and costs $200-$600 depending on project scope. Some installations may also require electrical permits if integrated lighting or ventilation systems are included.

  • How long does commercial skylight installation take?

    Most single skylight installations on commercial flat roofs take 1-2 days to complete, including curb installation, flashing, and weatherproofing. Multiple skylight projects typically require 3-5 days depending on quantity and complexity. Weather conditions significantly impact timeline, as installations require dry conditions for proper membrane adhesion. Complex installations involving structural modifications or electrical work may extend the timeline to a full week.
