Commercial Skylight Installation Process

At NSS Exteriors, we specialize in commercial skylight installations that transform buildings into brighter, more energy-efficient spaces for staff and visitors. Skylights are a vital addition to any commercial property because they enhance natural light, reduce the need for artificial lighting, and create more inviting environments for employees and customers. By strategically placing skylights, we help improve energy efficiency, lower utility costs, and promote occupant well-being with increased access to daylight. Whether you're upgrading an existing structure or planning a new project, our team delivers expert work quality and tailored solutions to meet your specific needs, elevating your commercial building. Below, We've provided valuable information about the commercial skylight installation process.

Essential Facts About Commercial Skylights

A commercial skylight is a professionally installed window structure integrated into the roof of a building to allow natural light to flood interior spaces. These skylights come in various types, including fixed skylights for constant lighting, ventilated skylights that provide light and airflow, and tubular skylights ideal for smaller areas. Installing skylights in commercial spaces offers numerous benefits. A few examples include needing less artificial lighting, lowering energy costs, and enhancing employee productivity and customer satisfaction by creating brighter, more inviting environments. Additionally, natural light improves mood and well-being, making skylights an excellent investment for modern commercial buildings.

Pre-Installation Planning

NSS Exteriors emphasizes the importance of thorough pre-installation planning when adding commercial skylights. The process begins with assessing the building structure to determine load capacity, roof type, and optimal placement, ensuring we can install the skylights safely and effectively. Next, choosing the right skylight is crucial. Factors like size, shape, energy efficiency, and purpose must align with the building’s needs. Finally, obtaining the necessary permits is essential to comply with local regulations and building codes, avoiding potential delays. Proper pre-installation planning streamlines the installation process and ensures long-term performance and benefits with the final results.

Tools & Materials Needed for Installation

Having all the appropriate tools, products, and materials is essential when you start a commercial skylight installation project. NSS Exteriors has years of experience completing installations throughout Chicago and will gladly enhance your indoor commercial spaces with beautiful skylights. 

Step-by-Step Installation Process

Installing a commercial skylight can be time-consuming and complex, which tends to be daunting for DIY property owners. If you own or manage a commercial building, you may not have the time, training, or insurance coverage to handle a skylight installation without a qualified professional like NSS Exteriors. Our team follows a trusted installation process to ensure site safety and stellar final results with long-lasting benefits. We’ve listed each general step of the commercial skylight installation process below to help you stay informed about how our team carries out your project:

  1. Prepare the Roof – We must prepare the relevant surfaces and ensure wiring, pipes, and other obstacles are out of the way before installing the new skylight.
  2. Cut the Opening – Our team cuts a carefully measured opening through the ceiling and building roof according to your new skylight’s precise measurements.
  3. Install the Skylight Frame – Using nails, screws, or another type of fastener, we securely attach the skylight frame to the opening.
  4. Sealing and Waterproofing – After the frame is in place, our professionals carefully seal and waterproof the perimeter using caulk, sealant, flashing, and other materials.
  5. Finishing Touches – The final step includes painting and other design touches to complete the integrated skylight look so it matches or complements your building interior’s aesthetic.

Common Challenges and Solutions

We strongly recommend seeking professional assistance when installing a commercial skylight if you have any potential safety issues, complications with structural components, or other problems that hinder the process or put people or property at risk. However, we also offer advice about common challenges and troubleshooting, including the following:

  1. Heat Gain or Loss – Opt for skylights with insulated glazing and low-emissivity (Low-E) coatings to regulate indoor temperatures effectively.
  2. Structural Integrity Issues – Conduct a structural assessment beforehand to confirm the roof can support the skylight. Reinforce areas as needed to maintain stability.
  3. Glare and Light Management – Install light diffusers or adjustable blinds to control excessive brightness and distribute light evenly.
  4. Compliance with Building Codes – Research and adhere to local codes early, obtaining all necessary permits to avoid delays or fines.

Post-Installation Care and Maintenance

Regular skylight maintenance is crucial to ensure optimal performance, safety, and longevity. Over time, debris, dirt, and weather elements can compromise the functionality of a skylight, leading to issues like leaks or diminished light transmission. Recommended maintenance practices include cleaning the glass surface with non-abrasive cleaners, inspecting seals for cracks, and checking flashing for proper adherence. It’s also essential to clear gutters or roof areas of debris to prevent water buildup around the skylight. Signs that repairs are necessary include visible water leaks, condensation between glass panes, drafts, or noticeable structural damage. Addressing these promptly prevents further complications.
