Let There Be Light: 5 Key Considerations Before Your Skylight Installation

    There is something magical about natural light flooding a room from above. It can make a small bathroom feel like a spa or a dark, narrow hallway feel open and airy. A skylight is more than a window; it's an architectural feature that can truly transform a space and your connection to the outdoors. At DISCOUNTED ROOFING LLC, we love installing them, but we also believe in doing it right. A successful skylight project is all about preparation, and it starts with asking the right questions before the work begins.

    First, consider placement, because it is everything. This decision affects not just where the light lands, but what kind of light you get. A north-facing skylight is a fantastic choice for artists or home offices, as it provides cool, consistent, and indirect light all day. Conversely, a south-facing skylight will give you bright, direct, and warm light, but you must consider the heat gain. In the summer, this can make a room uncomfortably warm, so you'd want to opt for a model with built-in blinds or special glazing. East-facing skylights give you bright morning light, while west-facing ones capture the warm afternoon sun.

    Next, you need to decide between a fixed or a vented model. Do you just want light, or do you want fresh air, too? A fixed skylight is essentially a sealed window for your roof. It's a simpler, often more affordable option. A vented skylight, on the other hand, can be opened (either manually with a crank or via a remote control). This is an ideal choice for bathrooms and kitchens, as it allows you to vent hot, moist air, which helps control humidity and odors. Releasing that hot air, which naturally rises, can also help cool your home in the warmer months.

    The third consideration is the glass itself, and modern technology has given us amazing options. You will want to look for high-performance glazing. This includes features like Low-E coatings, which are microscopically thin metallic layers that reflect infrared light. This keeps your home warmer in the winter by reflecting heat back in, and cooler in the summer by reflecting solar heat out. This coating also blocks a significant portion of UV rays, which is what causes your furniture, rugs, and artwork to fade over time. This small upgrade in glass makes a massive difference in energy efficiency and comfort.

    Of course, the number one concern for every homeowner is the potential for leaks. This is where the installation itself becomes the most important factor. A leak is almost never a failure of the skylight itself, but a failure of the installation. The key to a leak-proof skylight is the "flashing," which is the custom-fit metal shielding woven into your roofing shingles and around the skylight's frame. This system is designed to channel water down and away from the opening. For a SKYLIGHT INSTALLATION Philadelphia homeowners know our weather can be tough, which is why this is one job that is absolutely not a DIY project. It requires a professional roofer who understands how to integrate the unit flawlessly into the roof's water-shedding system.

    Finally, think about how the light will get from the roof to your ceiling. If you have an open, vaulted ceiling, the skylight is installed directly. But if you have an attic, the installer will need to build a "light shaft." This shaft can be flared, with the sides angled out, which helps to spread the light over a wider area of the room. A straight shaft will provide a more concentrated, spotlight-like effect. The inside of this shaft can be painted white to maximize reflection, adding to the brightness.

    A skylight is a wonderful, value-adding addition to any home, but it's a project where planning and professional expertise are essential. By considering these five points, you move from just 'wanting a skylight' to designing an installation that is energy-efficient, leak-free, and perfectly suited to your space. The result is all the joy of natural light with none of the worry.
