DIY Skylight Installation Guide: Increase Natural Light and Value of Your Home

Installing a skylight is a great way to bring natural light into your home and improve its overall look. Not only will it add value to your property, but it will also create a more pleasant living environment. Skylights can also help reduce energy costs by bringing natural light into the home, thus reducing the need for electric lights during the day. However, there are also some potential downsides to installing a skylight, such as the cost of installation and the potential for leaks if not installed properly. In this guide, we will walk you through the steps of installing a skylight, from planning and preparation to final installation, with the help of detailed illustrations and diagrams, and added information on different types of skylights, tips on sealing and troubleshooting leaks, and a list of recommended tools and materials.

Step 1: Planning and Preparation

• Determine the best location for your skylight. Consider factors such as the direction of the sun and the location of other windows and doors in the room. The ideal location for a skylight would be a room that does not receive much natural light and is in need of additional light.
• Measure the area where the skylight will be installed to determine the size and type of skylight you will need. The size of the skylight should be proportionate to the size of the room and the amount of natural light you want to bring in.
• Check local building codes to ensure that your skylight installation meets all necessary requirements. Building codes vary by state and municipality, so it is important to check with your local building department for specific requirements in your area.
• Gather all necessary tools and materials, including a skylight, flashing kit, roofing cement, and sealant. Make sure to get a skylight that is rated for the climate in your area.
• Consider the different types of skylights available such as fixed skylights, venting skylights, and tubular skylights to decide the best option for your home.

Step 2: Removing the Old Roofing Material

• Remove the shingles or other roofing material from the area where the skylight will be installed. It is important to remove enough of the roofing material to ensure a secure installation of the skylight.
• Cut a hole in the roof decking to match the size of the skylight. It is important to use the proper tools and techniques to cut the hole to ensure a secure fit for the skylight.
• Install the flashing kit around the hole to prevent leaks. The flashing is an important component of the installation and helps to protect the interior of your home from water leaks.
• Make sure to properly seal the skylight and flashing to prevent leaks by using recommended sealants and the proper technique for application.

Step 3: Installing the Skylight

• Place the skylight into the hole in the roof decking. Make sure the skylight is level and properly aligned before securing it in place.
• Secure the skylight in place with roofing cement and sealant. It is important to use a high-quality sealant to ensure a tight seal between the skylight and the roof decking.
• Install the flashing around the skylight to further prevent leaks. The flashing is usually made of metal and is designed to channel water away from the skylight and into the gutters.
• In case of leaks, information on how to repair them would be helpful for troubleshooting.

Step 4: Finishing the Interior

• Install a drywall or other finish material around the skylight to complete the interior of the room. It is important to choose a finish material that is compatible with the skylight and the existing decor of the room.
• Paint or otherwise finish the skylight to match the existing decor of the room.

Step 5: Testing and Maintenance

• Check for leaks by running water over the skylight and flashing. This can be done by using a hose to simulate rain, and checking for any signs of water leakage.
• Regularly maintain the skylight by cleaning it and checking for any signs of damage. It is important to keep the skylight clean to ensure that it is functioning properly and to prevent leaks.

Step 6: Insulation

• Add insulation around the skylight to prevent heat loss and increase energy efficiency. Insulating the skylight will help keep the room at a comfortable temperature and can also help reduce energy costs. It is important to use insulation that is compatible with the skylight and the roofing material. For more details on proper insulation of skylights you can check out this PDF by the U.S. EPA (Thermal Enclosure System Rater Checklist Guidebook).

Step 7: Ventilation

• Consider installing a venting skylight to allow fresh air and prevent moisture buildup. A venting skylight can be opened to allow fresh air into the room and can also be closed to prevent moisture from entering the room. This is especially important in bathrooms and kitchens where moisture levels can be high.

Step 8: Electric Wiring

• If you want to add a light, fan in the skylight or are planning on using an electric powered Vented Skylights, make sure to run electric wires to the skylight location. This can be done by running the wires through the attic or walls. Consult an electrician if you are not comfortable with electrical wiring.

Step 9: Covering

• Consider adding a skylight cover to block the sun during the summer or to prevent snow or debris from entering the skylight. Skylight covers can be made of a variety of materials such as fabric, plastic or metal. They can be manual or motorized and can be installed on the inside or outside of the skylight.

Step 10: Safety

• Make sure the skylight is properly secured and is not a tripping hazard. This includes making sure the skylight is level and properly aligned, and that it is properly secured to the roof decking.

Step 11: Professional Inspection

• Before finalizing the project, it is advisable to get a professional inspection to ensure the skylight has been installed correctly and meets all safety standards. A professional inspector can also check for any potential issues and make recommendations for any necessary repairs.

Step 12: Cleaning

• Clean the skylight and surrounding areas to ensure a polished and professional look. This includes removing any debris or dust from the skylight and the surrounding areas, and cleaning the skylight with a mild soap and water.

Installing a skylight can greatly improve the look and feel of your home, as well as its value. The addition of detailed illustrations and diagrams, information on different types of skylights available, tips on how to properly seal the skylight and flashing, information on how to repair leaks, and a list of recommended tools and materials makes the guide more comprehensive and easier for anyone to follow. Remember to always check with local building codes and get professional inspection before finalizing the project. It's also important to keep in mind that working on the roof can be dangerous, and if you're not comfortable with working at heights or with the tools and materials involved, it's best to hire a professional.
