Is it time for a bubble skylight replacement? Dome skylights play a vital role in enhancing the lighting in your home. They can brighten living spaces and provide fresh air. Bubble skylights, popular in the 1980s, are a common type found in many homes. These skylights are typically made of plastic or acrylic materials, allowing a clear view of the sky.
However, over time, these skylights may discolor, crack, or become inefficient. This article will guide you through the process of replacing an old bubble skylight. You’ll learn the benefits of a replacement skylight and understand the importance of coordinating skylight replacement with roof work.
What is a Bubble Skylight?
A bubble skylight, often made of plastic or acrylic, is designed to allow natural light into your home. Its dome shape helps shed water and prevents leaks. These skylights come in various sizes and shapes, including square and rectangular options.
Benefits of Plastic Bubble Skylights
Bubble skylights are lightweight and easy to install. They provide a wide view of the sky, adding a visually appealing element to your living spaces. Additionally, their design helps reduce heat escape and cooling costs.
Common Issues with Older Bubble Skylights
Over the years, plastic skylights can develop problems. The acrylic or plastic material may become discolored or cracked, affecting the skylight’s clarity and efficiency. Water leaks and drafts are common issues, leading to increased energy costs. Regular maintenance can prevent these problems, but eventually, a skylight replacement may be necessary.
Signs It’s Time to Replace Your Bubble Skylight
Visible Damage or Cracks
Dome skylights can suffer from visible damage over time. Cracks or breaks in the acrylic material can compromise the skylight’s integrity. If you see damage, it’s time to consider a skylight replacement to maintain your home’s safety and energy efficiency.

Water Leaks and Drafts
Water leaks are a clear sign that your plastic skylight is no longer effective. These leaks can lead to water damage in your home and increase energy costs. Drafts around the skylight are another indicator that it may need replacing.
Yellowing or Cloudiness
Older acrylic skylights often turn yellow or become cloudy. This discoloration reduces the amount of natural light entering your home and affects the skylight’s appearance. A new, clear replacement skylight will restore both function and aesthetics.
Increased Energy Bills
If your energy bills have risen, your old skylight might be the cause. Inefficient skylights can let heat escape in the winter and allow excessive heat in during the summer, leading to higher cooling costs. A new skylight will be more energy-efficient and help reduce these expenses.
Recognizing these signs early can save you from bigger issues and ensure your home remains comfortable and energy-efficient.
